随着人们生活水平的日益提高，越来越多的人喜欢自驾游或越野体验。市场上四驱车型的销量也水涨船高。尤其是随着智能物联的发展，便利的人机交互显示，也成为用户选择汽车的一个重要考虑因素。As people's living standards continue to improve, more and more people like to travel by car or experience off-road. The sales of four-wheel drive models in the market are also rising. Especially with the development of smart Internet of Things, convenient human-computer interaction display has also become an important consideration for users to choose cars.
矢量四驱汽车动力系统一般由矢量四驱系统主要功能是实现车辆前轴和左右后轮的扭矩分配。汽车在行驶时,由于油门开度、车轮滑移率、方向盘转角、横向加速度等信号实时变化，矢量四驱扭矩分配比例也是实时变化的。The power system of vector four-wheel drive vehicles is generally composed of a vector four-wheel drive system whose main function is to realize the torque distribution between the front axle and the left and right rear wheels of the vehicle. When the car is driving, due to the real-time changes of signals such as throttle opening, wheel slip rate, steering wheel angle, lateral acceleration, etc., the vector four-wheel drive torque distribution ratio also changes in real time.
但是，目前HMI界面(人机界面)扭矩输出显示仅体现桥间扭矩，无法精确显示两后轮的扭矩差异，具有局限性；更重要的是，桥间扭矩的显示需主机读取整车不同控制器的信号，经过复杂的计算得出，增加网络负载及影响控制器的算力，且计算存在失真。However, the current HMI (human-machine interface) torque output display only reflects the inter-axle torque and cannot accurately display the torque difference between the two rear wheels, which has limitations. More importantly, the display of inter-axle torque requires the host to read the signals of different controllers of the vehicle and obtain them through complex calculations, which increases the network load and affects the computing power of the controller, and the calculation is distorted.

The torque signal of each wheel of the vector four-wheel drive torque manager on the CAN bus is directly obtained through the host or large screen. The energy flow of the left rear wheel, the right rear wheel, the left front wheel and the right front wheel are obtained by the ratio method. The ratio of the torque between each wheel can be displayed intuitively and displayed through the energy bar. The signal is optimized, and the left rear wheel torque, the right rear wheel torque and the single-sided front wheel torque directly output by the four-wheel drive torque manager are used. It has the advantages of simple calculation and few signals involved; moreover, the working status of the vector four-wheel drive is directly and clearly fed back to the user, so that customers can feel the torque changes between the axles and wheels of the vector four-wheel drive more clearly, and let customers intuitively feel the intervention of the four-wheel drive and experience the controllability, safety and escape ability brought by the vector four-wheel drive configuration.
本实施例提供的一种矢量四驱能量流动态显示控制方法，如图1所示，包括如下步骤：A vector four-wheel drive energy flow dynamic display control method provided in this embodiment, as shown in FIG1 , includes the following steps:
步骤1、仪表或主机大屏实时从CAN总线上获取矢量四驱扭矩管理器各个轮的扭矩信号(包括左后轮扭矩EstimatedCouplingTorqLef、右后轮扭矩EstimatedCouplingTorqRight和单侧前轮扭矩EstimatedTorqFrntAxle)。Step 1: The instrument panel or the main engine screen obtains the torque signals of each wheel of the vector four-wheel drive torque manager (including the left rear wheel torque EstimatedCouplingTorqLef, the right rear wheel torque EstimatedCouplingTorqRight and the single-side front wheel torque EstimatedTorqFrntAxle) from the CAN bus in real time.
其中，所有信号(包括左后轮扭矩EstimatedCouplingTorqLef、右后轮扭矩EstimatedCouplingTorqRight和单侧前轮扭矩EstimatedTorqFrntAxle)均由扭矩管理器输出。Among them, all signals (including the left rear wheel torque EstimatedCouplingTorqLef, the right rear wheel torque EstimatedCouplingTorqRight and the unilateral front wheel torque EstimatedTorqFrntAxle) are output by the torque manager.
其中，EstimatedCouplingTorqLef左后轮扭矩、EstimatedCouplingTorqRight右后轮扭矩由离合器的速差、温度、位置查询Map图得出。Among them, EstimatedCouplingTorqLef left rear wheel torque and EstimatedCouplingTorqRight right rear wheel torque are obtained by querying the map of the speed difference, temperature and position of the clutch.
步骤2、判断整车电源状态，若整车电源状态处于ACC(车内部分电器供电状态)、ON(车内所有电器供电状态)、Crank(发动机点火状态)，则左后轮百分比(左后轮能量流)和右后轮百分比(右后轮能量流)均为0％，左前轮百分比(左前轮能量流)和右前轮百分比(右前轮能量流)均为0％；若整车电源状态处于Running(发动机运行状态)，执行步骤3。Step 2, determine the power status of the whole vehicle. If the power status of the whole vehicle is in ACC (power supply status of some electrical appliances in the vehicle), ON (power supply status of all electrical appliances in the vehicle), Crank (engine ignition status), the left rear wheel percentage (left rear wheel energy flow) and the right rear wheel percentage (right rear wheel energy flow) are both 0%, and the left front wheel percentage (left front wheel energy flow) and the right front wheel percentage (right front wheel energy flow) are both 0%; if the power status of the whole vehicle is in Running (engine running status), execute step 3.
即，前置条件:整车电源状态处于ACC、ON、Crank；触发条件:NA(无)；执行驱动输出:左后/右后轮百分比均为0％,左前/右前轮百分比均为0％。That is, precondition: the vehicle power state is in ACC, ON, Crank; trigger condition: NA (none); execution drive output: the left rear/right rear wheel percentages are both 0%, and the left front/right front wheel percentages are both 0%.
步骤3、判断档位，若档位处于P档(驻车挡)或N档(空挡)，则左后轮百分比(左后轮能量流)和右后轮百分比(右后轮能量流)均为0％，左前轮百分比(左前轮能量流)和右前轮百分比(右前轮能量流)均为0％；若档位处于R档(倒车挡)或D档(前进挡)，执行步骤4。Step 3, determine the gear position. If the gear position is in P gear (parking gear) or N gear (neutral gear), the left rear wheel percentage (left rear wheel energy flow) and the right rear wheel percentage (right rear wheel energy flow) are both 0%, and the left front wheel percentage (left front wheel energy flow) and the right front wheel percentage (right front wheel energy flow) are both 0%; if the gear position is in R gear (reverse gear) or D gear (forward gear), execute step 4.
即，前置条件:整车电源状态处于Running，P挡或N挡；触发条件:NA；执行驱动输出:a.左后/右后轮百分比均为0％,左前/右前轮百分比均为0％。That is, precondition: the vehicle power state is in Running, P gear or N gear; trigger condition: NA; execution drive output: a. The left rear/right rear wheel percentages are both 0%, and the left front/right front wheel percentages are both 0%.
步骤4、判断变速箱输出扭矩(DCTTqOut)是否大于设定值0，若是，则执行步骤5；否则，左后轮百分比(左后轮能量流)和右后轮百分比(右后轮能量流)均为0％，左前轮百分比(左前轮能量流)和右前轮百分比(右前轮能量流)均为0％。Step 4, determine whether the transmission output torque (DCTTqOut) is greater than the set value 0. If so, execute step 5; otherwise, the left rear wheel percentage (left rear wheel energy flow) and the right rear wheel percentage (right rear wheel energy flow) are both 0%, and the left front wheel percentage (left front wheel energy flow) and the right front wheel percentage (right front wheel energy flow) are both 0%.
即，前置条件:整车电源状态处于Running，R档或D挡；触发条件:DCTTqOut<＝0；执行驱动输出:左后/右后轮百分比均为0％,左前/右前轮百分比均为0％。That is, the precondition: the vehicle power state is in Running, R gear or D gear; the trigger condition: DCTTqOut<=0; the drive output is executed: the left rear/right rear wheel percentages are both 0%, and the left front/right front wheel percentages are both 0%.
步骤5、基于左后轮扭矩EstimatedCouplingTorqLef、右后轮扭矩EstimatedCouplingTorqRight，计算后桥扭矩占比，判断后桥扭矩占比是否大于阈值(50％)，若是，则执行步骤6；否则，执行定义2：左后轮百分比为EstimatedCouplingTorqLef/DCTTqOut，右后轮百分比为EstimatedCouplingTorqRight/DCTTqOut，左前/右前轮(即，单侧前轮)百分比均为EstimatedTorqFrntAxle＝(DCTTqOut-EstimatedCouplingTorqLef-EstimatedCouplingTorqRight)*50％/DCTTqOut。即，用总扭矩减去左右后轮扭矩得到前桥扭矩，然后乘50％得到单侧前轮扭矩，再除以总扭矩，得到单侧前轮扭矩。Step 5: Based on the left rear wheel torque EstimatedCouplingTorqLef and the right rear wheel torque EstimatedCouplingTorqRight, calculate the rear axle torque ratio, and determine whether the rear axle torque ratio is greater than the threshold value (50%). If so, execute step 6; otherwise, execute definition 2: the percentage of the left rear wheel is EstimatedCouplingTorqLef/DCTTqOut, the percentage of the right rear wheel is EstimatedCouplingTorqRight/DCTTqOut, and the percentage of the left front wheel/right front wheel (i.e., unilateral front wheel) is EstimatedTorqFrntAxle＝(DCTTqOut-EstimatedCouplingTorqLef-EstimatedCouplingTorqRight)*50％/DCTTqOut. That is, the front axle torque is obtained by subtracting the left and right rear wheel torques from the total torque, and then multiplying by 50% to obtain the unilateral front wheel torque, and then divided by the total torque to obtain the unilateral front wheel torque.
其中，后桥扭矩占比＝(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)/DCTTqOut。Among them, the rear axle torque proportion = (EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)/DCTTqOut.
即，前置条件:整车电源状态处于Running，R档或D挡；触发条件:DCTTqOut>0，0<＝(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)/DCTTqOut<＝50％；执行驱动输出:That is, precondition: the vehicle power state is in Running, R gear or D gear; trigger condition: DCTTqOut>0, 0<=(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)/DCTTqOut<=50%; execute drive output:
左后轮百分比为EstimatedCouplingTorqLef/DCTTqOut；The percentage of the left rear wheel is EstimatedCouplingTorqLef/DCTTqOut;
右后轮百分比为EstimatedCouplingTorqRight/DCTTqOut；The percentage of the right rear wheel is EstimatedCouplingTorqRight/DCTTqOut;
左前/右前轮(即，单侧前轮)百分比均为EstimatedTorqFrntAxle＝(DCTTqOut-EstimatedCouplingTorqLef-EstimatedCouplingTorqRight)*50％/DCTTqOut。The percentages of the left front wheel/right front wheel (ie, one-sided front wheel) are both EstimatedTorqFrntAxle=(DCTTqOut-EstimatedCouplingTorqLef-EstimatedCouplingTorqRight)*50%/DCTTqOut.
其中，DCTTqOut为变速箱输出扭矩。Among them, DCTTqOut is the gearbox output torque.
步骤6(定义3)、左前/右前轮(即，单侧前轮)百分比均为EstimatedTorqFrntAxle＝25％；左后轮百分比为EstimatedCouplingTorqLef/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50％；右后轮百分比为EstimatedCouplingTorqRight/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50％。Step 6 (Definition 3), the percentage of the left front/right front wheel (i.e., single-sided front wheel) is EstimatedTorqFrntAxle=25%; the percentage of the left rear wheel is EstimatedCouplingTorqLef/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50%; the percentage of the right rear wheel is EstimatedCouplingTorqRight/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50%.
即，前置条件:整车电源状态处于Running，R档或D挡；触发条件:DCTTqOut>0，(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)/DCTTqOut>50％；执行驱动输出:That is, precondition: the vehicle power state is in Running, R gear or D gear; trigger condition: DCTTqOut>0, (EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)/DCTTqOut>50%; execute drive output:
左前/右前轮(即，单侧前轮)百分比均为EstimatedTorqFrntAxle＝25％；The percentage of the left front wheel/right front wheel (ie, the front wheel on one side) is EstimatedTorqFrntAxle=25%;
左后轮百分比为EstimatedCouplingTorqLef/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50％；The percentage of the left rear wheel is EstimatedCouplingTorqLef/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50%;
右后轮百分比为EstimatedCouplingTorqRight/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50％。The right rear wheel percentage is EstimatedCouplingTorqRight/(EstimatedCouplingTorqLef+EstimatedCouplingTorqRight)*50%.
步骤7、将计算得到的左前轮百分比、右前轮百分比、左后轮百分比和右后轮百分比，以进度条的方式显示于仪表或主机大屏。Step 7: Display the calculated left front wheel percentage, right front wheel percentage, left rear wheel percentage and right rear wheel percentage on the instrument panel or main unit screen in the form of a progress bar.
本实施例提供的一种矢量四驱能量流动态显示控制方法，仪表或主机大屏从CAN总线上获取矢量四驱扭矩管理器实时轮间扭矩，根据EstimatedTorqFrntAxle单侧前轮扭矩，显示左/右前轮的能量流；根据EstimatedCouplingTorqLef左后轮扭矩、EstimatedCouplingTorqRight右后轮扭矩，显示左/右后轮的能量流。所述信号均由扭矩管理器计算输出，其中EstimatedCouplingTorqLef左后轮扭矩、EstimatedCouplingTorqRight右后轮扭矩由离合器的速差、温度、位置查询Map图得出。This embodiment provides a method for dynamically displaying and controlling the energy flow of a vector four-wheel drive. The instrument or the main engine screen obtains the real-time wheel-to-wheel torque of the vector four-wheel drive torque manager from the CAN bus, and displays the energy flow of the left/right front wheel according to the EstimatedTorqFrntAxle unilateral front wheel torque; and displays the energy flow of the left/right rear wheel according to the EstimatedCouplingTorqLef left rear wheel torque and the EstimatedCouplingTorqRight right rear wheel torque. The signals are all calculated and output by the torque manager, wherein the EstimatedCouplingTorqLef left rear wheel torque and the EstimatedCouplingTorqRight right rear wheel torque are obtained by querying the Map diagram of the speed difference, temperature, and position of the clutch.
例如，总扭矩2000Nm，左后轮扭矩600Nm，右后轮扭矩400Nm，但不代表本发明扭矩管理器轮间扭矩信号只能为该值，该扭矩根据整车需求发送不同数值的信号，动态显示。For example, the total torque is 2000Nm, the left rear wheel torque is 600Nm, and the right rear wheel torque is 400Nm, but this does not mean that the inter-wheel torque signal of the torque manager of the present invention can only be this value. The torque sends signals of different values according to the needs of the whole vehicle and is dynamically displayed.
计算公式如下：The calculation formula is as follows:
单侧前轮扭矩比例：(2000Nm-600Nm-400Nm)/2000Nm＝25％；Unilateral front wheel torque ratio: (2000Nm-600Nm-400Nm)/2000Nm=25%;
左后轮扭矩比例：600Nm/2000Nm＝30％；Left rear wheel torque ratio: 600Nm/2000Nm=30%;
右后轮扭矩比例：400Nm/2000Nm＝20％。Right rear wheel torque ratio: 400Nm/2000Nm=20%.
如图2所示，仪表或主机大屏接收四驱扭矩管理器实时轮间信号扭矩值，通过简单计算后，体现为进度条长短无极调节显示四轮扭矩比例，不体现具体百分比，解决计算后取值有可能总和超过100％的观感问题。As shown in Figure 2, the instrument or host large screen receives the real-time wheel-to-wheel signal torque value of the four-wheel drive torque manager. After simple calculation, it is reflected as a progress bar with infinitely adjustable length to display the four-wheel torque ratio. The specific percentage is not reflected, which solves the visual problem that the total value after calculation may exceed 100%.
