The embodiment of the invention provides a hill starting control method and system, a controller and a vehicle, relates to the technical field of vehicle control, and can control the depth of an accelerator pedal without depending on a driver, avoid vehicle sliding and realize reliable hill starting at any gradient. The hill starting control method comprises the steps that when an automatic parking function is activated, basic torque needed for keeping a vehicle static on a current ramp is determined; receiving a driver request torque curve from a vehicle control unit; in response to the fact that the torque requested by the driver at the moment T1 is larger than the set torque and smaller than the basic torque, the automatic parking function is controlled to be released, a first ESC torque request is sent to a vehicle control unit, and the first ESC torque request indicates that the vehicle is controlled to be static according to the basic torque; and in response to the fact that the driver request torque at the T2 moment exceeds the basic torque, a second ESC torque request is sent to the vehicle control unit, and the second ESC torque request is used for indicating to control vehicle starting according to the driver request torque.
本申请实施例提供了一种坡道起步的控制方法、系统、控制器及车辆,涉及车辆控制技术领域,能够无需依赖于驾驶员来控制加速踏板的深浅,避免出现溜车,实现在任意坡度下可靠地坡道起步。其中,坡道起步的控制方法包括:当自动驻车功能激活时,确定在当前坡道维持车辆静止所需的基础扭矩;接收来自整车控制器的驾驶员请求扭矩曲线;响应于T1时刻的驾驶员请求扭矩大于设定扭矩,且小于基础扭矩,控制自动驻车功能释放,且向整车控制器发送第一ESC扭矩请求,第一ESC扭矩请求指示根据基础扭矩来控制车辆处于静止;响应于T2时刻的驾驶员请求扭矩超过基础扭矩,向整车控制器发送第二ESC扭矩请求,第二ESC扭矩请求用于指示根据驾驶员请求扭矩来控制车辆起步。
