The invention discloses a hill starting control method and system and a vehicle, and relates to the technical field of vehicles. According to the method, when the vehicle is parked on the ramp, the automatic parking function of the vehicle is triggered to be activated, the basic torque is determined based on the obtained road gradient, the first torque request value is generated based on the basic torque and sent to the motor controller, and then after it is determined that the opening degree of an accelerator pedal of the vehicle is changed, the motor controller is started. Adjusting a driving mode of the vehicle to include determining a target torque including a base torque, a first adjustment torque determined based on a brake pedal opening and an accelerator pedal opening of the vehicle, and an assist torque determined by the creep control module, generating a second torque request value based on the target torque, and the second torque request value is sent to the motor controller in the hill starting auxiliary mode. Therefore, the problems of poor stability and poor driving comfort easily caused by the fact that the vehicle completes hill starting through the preset fixed torque or a simple accelerometer are solved.
本申请公开了一种坡道起步控制方法、系统及车辆,涉及车辆技术领域。该方法通过在车辆在坡道驻车时,触发车辆的自动驻车功能激活,并基于获取的道路坡度确定基础扭矩,以基于基础扭矩生成第一扭矩请求值向电机控制器发送,而后在确定车辆的油门踏板开度发生变化后,将车辆的驾驶模式调整为包括确定包括基础扭矩、基于车辆的制动踏板开度和油门踏板开度确定的第一调整扭矩,以及由蠕行控制模块确定的辅助扭矩的目标扭矩,基于目标扭矩生成第二扭矩请求值,将第二扭矩请求值向电机控制器发送的坡道起步辅助模式。从而解决了车辆通过预设固定扭矩或简单加速度计来完成坡道起步,容易造成的平稳性差、驾驶舒适性不佳的问题。
