The invention discloses a vehicle control method, a vehicle-mounted controller, a vehicle control system and an automobile. The method comprises the steps of determining a current working condition of a vehicle based on first vehicle data; when the current working condition of the vehicle is the slope working condition, based on the second vehicle data, the engine target rotating speed and the engine required torque are determined; determining a generator demand torque based on the engine target speed and the generator actual speed; and controlling the engine to work based on the engine demand torque and controlling the generator to work based on the generator demand torque. According to the method, the engine is controlled to work based on the engine demand torque, the generator is controlled to work based on the generator demand torque, the vehicle can be accurately and reasonably controlled under the slope road working condition, power and torque fluctuation is avoided, the vehicle operation stability is improved, oil consumption is reduced, and the purpose of effectively improving the NVH performance of the vehicle is achieved.

    本发明公开了一种车辆控制方法、车载控制器、车辆控制系统和汽车。该方法包括:基于第一车辆数据,确定车辆当前工况;在车辆当前工况为坡路工况时,基于第二车辆数据,确定发动机目标转速和发动机需求扭矩;基于发动机目标转速和发电机实际转速,确定发电机需求扭矩;基于发动机需求扭矩控制发动机工作,基于发电机需求扭矩控制发电机工作。该方法基于发动机需求扭矩控制发动机工作,并基于发电机需求扭矩控制发电机工作,能够在坡路工况下,较为精确合理地对车辆进行控制,避免功率和扭矩波动,提高车辆运行的稳定性,降低油耗,实现有效提高车辆的NVH性能的目的。
