The invention belongs to the technical field of automobile electric control, and particularly relates to a commercial vehicle constant-speed driving method and a vehicle. The method comprises the steps that a vehicle controller starts a vehicle constant-speed driving function module based on a received activation instruction; a controller of the vehicle constant-speed running function module judges whether the vehicle speed reaches a preset target vehicle speed or not, if not, the controller sends an adjusting instruction to an engine to adjust the rotating speed of the engine to a target rotating speed corresponding to the target vehicle speed, and the vehicle runs at a constant speed; and the vehicle controller closes the vehicle constant-speed driving function module based on the received quit instruction. According to the method, whether the vehicle speed reaches the preset target vehicle speed or not is judged through a controller of a vehicle constant-speed driving function module, if not, an adjusting instruction can be sent to an engine to adjust the rotating speed of the engine to the target rotating speed corresponding to the target vehicle speed, and the vehicle runs at the constant speed. The vehicle can run at a low speed of about 5km/h, and various requirements of different users in different scenes can be met.
本发明属于汽车电控技术领域,尤其是涉及一种商用车定速行驶方法及车辆,方法包括:整车控制器基于接收的激活指令启动车辆定速行驶功能模块;车辆定速行驶功能模块的控制器判断车速是否达到预设的目标车速,若否,控制器向发动机发出调节指令调节发动机转速至与目标车速对应的目标转速,使车辆定速行驶;整车控制器基于接收的退出指令关闭车辆定速行驶功能模块。本发明的方法通过车辆定速行驶功能模块的控制器判断车速是否达到预设的目标车速,若未达到,可向发动机发出调节指令调节发动机转速至与目标车速对应的目标转速,使车辆定速行驶。使车辆实现低至5km/h左右的低速定速行驶,可以满足不同用户、不同场景下的多种需求。
