Fig. 1 is a schematic diagram showing signal interaction among a tire pressure sensor, a tire pressure monitoring module, a vehicle body electronic stabilization module, a vehicle-mounted wireless terminal and a controller according to an embodiment of the present invention. The tire pressure sensor is used for detecting the tire temperature, the tire pressure and the ID information of the tire pressure sensor of the vehicle, the collected information is transmitted to the tire pressure monitoring module, the vehicle body electronic stabilizing module is used for receiving the speed of the vehicle, the tire pressure monitoring module sends the collected information to the vehicle-mounted wireless terminal, the vehicle-mounted wireless terminal sends the collected speed to the controller, and the controller calculates and analyzes the received information to realize fault diagnosis of the tire pressure.
Based on the information interaction between the above devices, a tire failure diagnosis method for a vehicle according to an embodiment of the present invention is illustrated below.
The following describes a tire failure diagnosis method of a vehicle according to an embodiment of the present invention with reference to fig. 1 and 2, and as shown in fig. 2, the tire failure diagnosis method of a vehicle according to an embodiment of the present invention includes at least steps S1 to S3.
Step S1, a tire pressure sensor ID of a vehicle and a vehicle speed of the vehicle are acquired.
The tire pressure sensor ID is provided in a corresponding vehicle tire, for example, and is a sensor for detecting information such as tire pressure and tire temperature. After the tire pressure and the tire temperature data of the vehicle are monitored through the tire pressure sensor, the data are uploaded to the tire pressure monitoring module, the ID of the tire pressure sensor is different, and the tire pressure and the tire temperature data of the corresponding detected tire of the vehicle are different. It is understood that the tire pressure sensor ID may be a front left tire pressure sensor ID, a front right tire pressure sensor ID, a rear left tire pressure sensor ID, and a rear right tire pressure sensor ID.
The vehicle speed of the vehicle, for example, the vehicle speed of the vehicle is received by the vehicle body electronic stability module during running, the tire pressure sensor ID of the vehicle and the vehicle speed of the vehicle are obtained to transmit the data to the controller, and the controller performs subsequent control according to the received tire pressure sensor ID and the vehicle speed.
And S2, determining the actual receiving quantity and the target receiving quantity of the tire pressure data corresponding to the tire pressure sensor ID in a preset time period when the vehicle speed is greater than a preset vehicle speed threshold value. It is understood that in order to prolong the service life of the tire pressure sensor, the tire pressure sensor is generally woken up and transmits tire pressure data to the vehicle when the vehicle speed is greater than or equal to a preset vehicle speed threshold, for example, 25km/h or more; in order to increase the accuracy of the tire pressure receiving rate analysis result, the preset time period can be selected to be 30 minutes at least, so that the tire pressure data is required to be analyzed when the vehicle speed is more than or equal to 25km/h and the duration is more than or equal to 30 minutes.
The tire pressure sensor IDs are identity attributes of the tire pressure sensors, and the tire pressure sensors corresponding to different tire pressure sensors are different in ID. The actual reception number of the tire pressure data corresponding to the tire pressure sensor ID is the actual reception number of the tire pressure data, for example, 50, 60, or 70 tire pressure data, in a preset period of time in which the vehicle speed is greater than a preset vehicle speed threshold, for example, 30 minutes. The target reception number is a target reception number of tire pressure data, for example, 90 tire pressure data, which should be received when the tire pressure sensor is free from a failure in a preset period of time, for example, 30 minutes.
In an embodiment, after the tire pressure sensor IDs and the vehicle speed are determined, when the vehicle speed satisfies a requirement, for example, the vehicle speed is greater than 25Km/h, and the actual reception number and the target reception number of the tire pressure data corresponding to each tire pressure sensor ID, for example, the actual reception number and the target reception number of the tire pressure data corresponding to the front left tire sensor ID, are determined within a preset period of time. By determining the actual reception number and the target reception number of the tire pressure data, the tire pressure failure type can be identified based on the actual reception number and the target reception number.
And S3, determining the tire pressure fault type according to the actual receiving quantity and the target receiving quantity.
The actual receiving number and the target receiving number of the tire pressure data corresponding to the tire pressure sensor ID are different, and the tire pressure fault type may be different, and it can be understood that the tire pressure fault type can be determined according to the analysis result by analyzing the actual receiving number and the target receiving number, so that the fault maintenance efficiency is improved, and the maintenance requirement of a user on the fault is met.
In the embodiment, after the actual receiving quantity and the target receiving quantity are determined, the tire pressure fault type is determined according to the relation between the actual receiving quantity and the target receiving quantity, so that maintenance personnel are prevented from carrying out field maintenance, manpower and material resources are wasted, and the convenience of fault maintenance is improved.
According to the tire fault diagnosis method of the vehicle, the tire pressure sensor ID is identified to determine the actual receiving quantity and the target receiving quantity of the tire pressure data corresponding to the tire pressure sensor ID, and the fault cause of the tire pressure lamp when the tire pressure lamp is lighted is primarily judged and analyzed according to the relation between the actual receiving quantity and the target receiving quantity, so that the tire pressure fault type is determined, a user is conveniently guided to maintain and process according to the fault type, and the fault maintenance efficiency is improved while the maintenance requirement of the user is met.
In some embodiments, determining the tire pressure fault type based on the actual number of receptions and the target number of receptions includes: determining a receiving rate of tire pressure data corresponding to the tire pressure sensor ID according to the actual receiving number and the target receiving number; and determining the tire pressure fault type according to the receiving rate. It can be understood that the receiving rate of the tire pressure data is determined according to the actual receiving number and the target receiving number, and the failure reason of the tire pressure failure lamp is analyzed according to the difference of the receiving rate so as to determine the corresponding tire pressure failure type, so that the user can be guided to process and maintain according to the failure type.
In an embodiment, the reception rate of the tire pressure data corresponding to the tire pressure sensor ID, that is, the tire pressure reception rate, represents the success rate of receiving the tire pressure data within a preset period of time.
For example, after the actual receiving number and the target receiving number are determined, the receiving rate of the tire pressure data corresponding to the tire pressure sensor ID is determined according to the actual receiving number and the target receiving number, for example, the receiving rate= (actual receiving number/target receiving number) ×100%, so that the closer the actual receiving number is to the target receiving number, the higher the receiving rate of the corresponding tire pressure data is, the different the receiving rate is, and the corresponding failure type is also different. By determining the reception rate, it is convenient to determine the tire pressure failure type from the reception rate.
Taking three tire pressure data received within 30 minutes per minute as an example, the target receiving number of the tire pressure data should be 30×3=90; however, the number of tire pressure data actually received may be only one or several. Therefore, the actual reception number and the target reception number need to be determined to calculate the reception rate.
In some embodiments, determining the tire pressure fault type from the reception rate includes: if the number of times that the receiving rate is lower than a first preset receiving rate threshold exceeds the preset number of times, determining that the tire pressure fault is a first type fault; and if the receiving rate is a second preset receiving rate threshold value, determining that the tire pressure fault is a second type fault, wherein the second preset receiving rate threshold value is smaller than the first preset receiving rate threshold value. Through comparing the relation between the receiving rate and the preset receiving rate threshold value, the fault type of the tire pressure can be accurately and rapidly determined.
In an embodiment, when determining the tire pressure fault type, the determination is performed according to the receiving rate, and the tire pressure sensor ID is taken as the left front tire pressure sensor ID to be illustrated, if the receiving rate of the left front tire pressure sensor is lower than a first preset receiving rate threshold, for example, the receiving rate is far lower than 80%, at this time, the left front tire pressure data can be primarily considered to receive electromagnetic interference, if the number of times of the receiving rate is lower than 80% exceeds a preset number of times, for example, 5 times, the tire pressure fault is determined to be a first type fault, that is, the tire pressure sensor is subjected to electromagnetic interference to cause a fault, after determining the fault type, a maintenance personnel can remotely instruct a user to check whether the vehicle uses an electronic device of a non-rule level, if the electronic device is removed or removed from the vehicle, the fault is released, and the tire pressure fault lamp is no longer on, the fault type is determined to be electromagnetic interference, and the user is informed that the same electronic device is not to be used later. It can be appreciated that in order to improve the accuracy of the fault diagnosis, the reception rate may be calculated a plurality of times when the reception rate is determined, and when the reception rate of one tire pressure sensor is greater than 80%, the tire pressure sensor is considered to satisfy the tire pressure system requirement; when the receiving rate of the four tire pressure sensors is greater than 80%, the requirement of the whole vehicle on the tire pressure is considered to be met.
If the receiving rate is a second preset receiving threshold, for example, the receiving rate is 0%, the left front tire pressure data is considered not to be received, if the receiving rates of the other tire pressure sensors are all normal, the second type of faults are considered to occur, namely, the left front tire pressure sensor is damaged, and at the moment, a maintenance personnel can remotely guide a user to replace the left front tire pressure sensor. By identifying the tire pressure sensor ID, the cause of the tire pressure failure lamp being lighted is preliminarily determined according to the reception rate, that is, the failure type is determined, and thus, the cost of failure maintenance is greatly reduced.
In some embodiments, before acquiring the tire pressure sensor ID of the vehicle and the vehicle speed of the vehicle, the method includes: and establishing a matrix list of tire pressure sensor IDs corresponding to the preset positions. Through establishing the matrix list that tire pressure sensor ID corresponds with the preset position, be convenient for directly carry out data call when confirming tire pressure sensor ID for tire pressure sensor ID's confirm more convenient.
In an embodiment, the tire pressure sensor ID corresponds to a preset position, the tire pressure sensor IDs corresponding to different preset positions are different, and the corresponding tire pressure sensor ID is conveniently determined according to the preset position by setting the correspondence between the preset position and the tire pressure sensor ID.
In some embodiments, determining the actual received quantity of tire pressure data corresponding to the tire pressure sensor ID includes: determining a preset position and a tire pressure signal value at the preset position, wherein the tire pressure signal value is used for indicating whether tire pressure data are received or not; determining an ID of the tire pressure sensor according to the preset position; and in a preset time period when the vehicle speed is greater than a preset vehicle speed threshold value, if the value is a preset tire pressure signal value, determining that the tire pressure data is received, and accumulating the received tire pressure data to determine the actual receiving quantity of the tire pressure data in the preset time. The received tire pressure data is accumulated in a preset time period when the vehicle speed is greater than the preset vehicle speed threshold value, so that the actual receiving quantity of the tire pressure data is more reliable, and the accuracy of the receiving rate calculation is improved.
In an embodiment, when the actual receiving number and the target receiving number are determined, a preset position and a tire pressure signal value corresponding to the preset position are determined, a tire pressure sensor ID corresponding to the position is determined according to the preset position, after the tire pressure sensor ID is determined, tire pressure data with a vehicle speed greater than or equal to a preset vehicle speed threshold, for example, a vehicle speed greater than or equal to 25Km/h and a time exceeding 30 minutes is screened, and the received tire pressure data is analyzed to determine the actual receiving number and the target receiving number.
Specifically, the tire pressure signal value corresponding to the preset position is analyzed to determine whether the tire pressure signal value is the preset tire pressure signal value, if the tire pressure signal value is the preset tire pressure signal value, for example, 0X0, the tire pressure data is considered to be received, if the tire pressure signal value is not the preset tire pressure signal value, for example, 0X2, the tire pressure data is considered not to be received, and whether the tire pressure data is received is determined by analyzing the tire pressure signal value in the preset position, so that the determination of the actual receiving quantity of the tire pressure data is realized.
In some embodiments, determining the tire pressure sensor ID from the preset location includes: and determining tire pressure sensor IDs corresponding to the preset positions in the matrix list. And the tire pressure sensor ID corresponding to the preset position is determined in the matrix list, so that the tire pressure sensor ID determination process is simpler and more convenient.
In an embodiment, when determining the tire pressure transmitter ID, a preset position is determined, and the ID of the tire pressure sensor is determined in the matrix list according to the preset position, it is understood that different preset positions correspond to different tire pressure sensor IDs in the matrix list.
In some embodiments, the fault diagnosis method of the vehicle tire pressure further includes: the reception rate of the tire pressure data corresponding to the tire pressure sensor ID is displayed.
In an embodiment, after the receiving rate of the tire pressure data is determined, the receiving rate is sent to the display module, so that a maintenance person can clearly know the receiving rate of the tire pressure data corresponding to the tire pressure sensor ID, and therefore a user is guided to conduct fault analysis according to the receiving rate, and fault analysis efficiency is improved.
In some embodiments, the fault diagnosis method of the vehicle tire pressure further includes: image information corresponding to the reception rate of the tire pressure data is displayed.
In the embodiment, the specific receiving rate can be replaced by the image information corresponding to the receiving rate, so that maintenance personnel can more intuitively know whether the current receiving rate is normal or not, and the method is more convenient and quick.
In other embodiments, when determining the tire pressure fault type, the vehicle speed and the tire pressure sensor ID are transmitted to the vehicle-mounted wireless terminal, the vehicle-mounted wireless terminal can transmit the data to the cloud platform, and a maintainer screens the data in a preset time period when the vehicle speed is greater than a preset vehicle speed threshold value by downloading the data of the cloud platform so as to determine the receiving rate, and the tire pressure fault type is determined according to the receiving rate, so that the fault maintenance efficiency is improved while the maintenance requirement of a user is met.
