The invention provides a hill starting control method and device, a vehicle control unit and a vehicle, and relates to the technical field of vehicles. The method comprises the steps that state information of a vehicle is acquired, and according to the state information of the vehicle, an anti-sliding function is determined to be enabled; when it is determined that the anti-sliding function is enabled, the current slope state of the vehicle is obtained; and the output torque of the motor is adjusted to be 0 according to the gradient state and the parameter corresponding to the gradient state. According to the control method for hill starting, when the enabling of the anti-sliding function is determined, the slope size recognition function is added, different adjustments can be carried out according to the slope size, the smoothness of the whole vehicle is improved, the problems that the vehicle shakes back and forth and the driving comfort of the vehicle is reduced due to the fact that the output torque of the motor is adjusted by fixed parameters are solved. According to the scheme, when the anti-sliding function is determined to be enabled, the sudden brake judgment condition is added, and unexpected entering of the anti-sliding function is completely eradicated.
本发明提供了一种坡道起步的控制方法、装置、整车控制器和车辆,涉及汽车技术领域。该方法包括:获取车辆的状态信息,并根据所述车辆的状态信息,确定防溜车功能使能;确定防溜车功能使能时,获取当前车辆所处的坡度状态;根据所述坡度状态,以及所述坡度状态对应的参数,将电机的输出转矩调节为0。本发明的坡道起步的控制方法在确定防溜车功能使能时,增加了坡度大小识别功能,可以根据所述坡度大小进行不同的调节,提高了整车平顺性,避免了因固定参数调节电机的输出转矩导致车辆来回晃动,降低车辆驾驶舒适性的问题,且本方案在确定防溜车功能使能时还加人了判定急刹的情况,杜绝了非预期进入防溜坡功能。
