The embodiment of the invention provides a constant-speed cruise torque control method, a controller, a constant-speed cruise system and a vehicle. The method comprises the steps of obtaining a firstmotor rotating speed and a first motor torque corresponding to a current first constant-speed cruise state when the vehicle is in a constant-speed cruise working condition; if the signal that an accelerator pedal is treaded is detected, acquiring the accelerator opening degree of the accelerator pedal and a preset first corresponding relationship between the accelerator opening degree and the motor rotating speed and the motor torque; according to the accelerator opening degree, the motor rotating speed and the first corresponding relationship, obtaining the compensation torque; and summing the first motor torque and the compensation torque to obtain a target motor torque, and sending the target motor torque to a motor controller. In the embodiment of the invention, the target motor torqueis the sum of the first motor torque and the compensation torque obtained according to the accelerator opening degree, so that when the vehicle is in the constant-speed cruise working condition, theaccelerated driving of the vehicle can be realized only by stepping on the accelerator pedal, and the user experience is facilitated to be improved.

    本发明的实施例提供了一种定速巡航的扭矩控制方法、控制器、定速巡航系统及车辆,其中,方法包括:当车辆处于定速巡航工况时,获取当前第一定速巡航状态对应的第一电机转速和第一电机扭矩;若检测到油门踏板被踩踏的信号,则获取油门踏板的油门开度以及预设的油门开度和电机转速与电机扭矩的第一对应关系;根据油门开度、电机转速以及第一对应关系,得到补偿扭矩;将第一电机扭矩和补偿扭矩求和,得到目标电机扭矩,并发送至电机控制器。在本发明的实施例中,目标电机扭矩是第一电机扭矩与根据油门开度得到的补偿扭矩之和,使得在车辆处于定速巡航工况时,只需要踩踏油门踏板即可实现车辆的加速行驶,有利于提升了用户体验。
