The invention is suitable for the technical field of automatic driving, and particularly relates to an automatic driving automobile speed limiting method and system. Environment parameter information is obtained, and a whole vehicle speed limit value is determined according to the environment parameter information; according to the vehicle running speed and the accelerator amount, a motor target torque value is calculated through a preset vehicle speed limiting algorithm; and controlling the motor according to the target torque value of the motor. According to the automatic driving automobile speed limiting method, the problem that frequent parameter adjustment is needed is avoided, speed adjusting control can be completed by confirming all basic parameters of the automobile at the beginning of design, frequent parameter adjustment is not needed, and development time and manpower cost are saved.

    本发明适用于自动驾驶技术领域,尤其涉及自动驾驶汽车限速方法及系统,所述方法包括:获取车辆行驶速度以及油门量;获取环境参数信息,根据环境参数信息确定整车限速值;根据车辆行驶速度以及油门量,通过预设的汽车限速算法计算电机目标扭矩值;按照电机目标扭矩值,对电机进行控制。本发明提供的一种自动驾驶汽车限速方法,规避了需要频繁调参的问题,在设计初通过对车辆各基本参数的确认即可完成调速控制,无需频繁调参,节省了开发时间和人力上的成本。
