Description

Vehicle-end unmanned remote fault resetting method

The technical field is as follows:

the invention relates to an unmanned remote fault resetting method for a vehicle end, and belongs to the technical field of intelligent networked vehicles.

Background art:

SAE divides the automatic driving technology into 6 grades from No Automation (No Automation) to Full Automation (Full Automation), and the intellectualization and the unmanned development are the development direction throughout the whole technical route. According to the current development situation, complex road conditions and occasional system failures which cannot be decided are two main problems requiring personnel intervention.

Remote driving is used as supplement of unmanned driving, and artificial take-over can be carried out when an unmanned driving system has complicated road conditions which cannot be responded; when a system fault of the vehicle occurs, a safety worker is often required to press a reset button on the vehicle to remove the system fault. In this way, when the vehicle driving range is large, much inconvenience is brought to the operation.

Aiming at solving the problems, the invention aims to realize the unmanned fault resetting method of the vehicle end, so that when the vehicle has system fault, the remote resetting can be realized, the resetting mode is simplified, and the operation cost is reduced.

The invention content is as follows:

the present invention provides a remote fault resetting method for vehicle end without human, which is to transfer the original reset function realized at the vehicle end to a remote cockpit when the vehicle has a system fault, so as to realize the vehicle end without human.

The technical scheme adopted by the invention is as follows: the utility model provides a car end unmanned remote fault reset method, realizes based on remote driving platform, remote driving platform includes car end equipment, high in the clouds equipment and cabin end equipment, and car end equipment includes whole car the control unit and car end gateway, and high in the clouds equipment includes remote data server and cloud ware, and cabin end equipment includes cabin end gateway, panel board, well accuse platform and vehicle system fault reset, and the step is as follows:

the method comprises the following steps: when the unmanned vehicle has a vehicle system fault, the vehicle end whole vehicle control unit informs a vehicle end gateway of a vehicle end state message, and the vehicle end gateway reads the state information from the gateway CAN, packages the state information and sends the state information to the remote data server;

step two: the cabin end VCU informs the cabin end gateway of the cabin end control message, and the cabin end gateway forwards the cabin end control message to the remote data server;

step three: the remote data server of the cloud equipment forwards data, after a central control platform of the cockpit successfully takes over a corresponding vehicle by pressing a button, the cloud platform forwards the received cockpit data to the vehicle which takes over the corresponding vehicle successfully to realize control, otherwise, the state data uploaded to the remote data server by the vehicle end can be forwarded to the cockpit and fed back to an operator.

Further, after the cabin gateway receives the vehicle system fault forwarded by the remote data server, the fault zone bit is displayed on a control interface of the cockpit, the fault zone bit exists in a virtual and interactive reset button mode, and when the button is bright, reset is clicked.

Furthermore, after the reset button of the cockpit is clicked, the cockpit gateway forwards the reset command to the gateway of the vehicle end through the remote data server, and the vehicle end gateway device responds to the reset command to reset the fault of the vehicle system.

The invention has the following beneficial effects: the unmanned remote fault resetting method for the vehicle end reuses the existing control link of remote driving, so that the vehicle can realize system fault resetting through the cockpit, operation and maintenance personnel do not need to operate on the vehicle, and the cost of vehicle operation and management is greatly reduced.

Description of the drawings:

FIG. 1 is a diagram of a remote driving platform model.

Fig. 2 is a flowchart of a remote fault resetting method for vehicle-side unmanned.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

The remote driving platform comprises vehicle-end equipment, cloud-end equipment and cabin-end equipment, wherein the vehicle-end equipment comprises a whole vehicle control unit (namely vcu) and a vehicle-end gateway (namely IMX of a vehicle end), the cloud-end equipment comprises a remote data server (namely DataServer) and a cloud server, the cabin-end equipment comprises the cabin-end gateway, an instrument panel, a central control platform and a vehicle system fault reset, and the vehicle system fault reset is a function button of the central control platform.

The invention discloses a remote fault resetting method without humanization at a vehicle end, which comprises the following steps:

the method comprises the following steps: when the unmanned vehicle has a vehicle system fault, the vehicle end vcu informs the vehicle end gateway of the vehicle end status message, and the vehicle end gateway reads the status information from the gateway can, packages the status information and sends the status information to the remote data server;

step three: the cloud device is used for receiving and sending the data of the cockpit, and sending the data of the cockpit to the remote data server, and sending the data of the cockpit to the instrument panel.

The connection state fault of the remote driving system is special, namely the fault occurs under the condition of poor network, and the fault bit disappears when the network state is recovered. If the CAN message of the vehicle state is directly analyzed at the cabin end gateway, the connection state fault of the remote driving system CAN be missed. Therefore, when a system fault occurs, the mode that the system fault mark is set and stored at the gateway of the vehicle end, and then the fault position is forwarded to the cabin end through the remote data server is reasonable.

After the cabin end gateway receives the vehicle system fault forwarded by the remote data server, the fault zone bit is displayed to a control interface of the cockpit and exists in a virtual and interactive reset button mode. When the button is on, the button can be clicked to reset; and the fault reset button displays a corresponding state according to the fault zone bit of the vehicle system forwarded by the remote data server, and is irrelevant to the operation times of manually clicking the control interface.

After a reset button of the cockpit is clicked, a reset command is forwarded to a gateway of the vehicle end through a remote data server by the cockpit gateway, and the vehicle end gateway equipment responds to the reset command to reset the fault of the vehicle system, so that an unmanned fault reset mechanism of the vehicle end is realized.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
