The invention discloses a braking method and system based on accelerator pedal opening. The method comprises the following steps: obtaining state information of a vehicle when the vehicle is in a preset working condition, wherein the state information includes gear information of the vehicle and opening information of an accelerator pedal; when the vehicle is in a preset gear, determining whetherthe vehicle meets a first preset condition according to the opening degree information of the accelerator pedal; when the vehicle meets the first preset condition, calculating a first deceleration according to the opening degree information of the accelerator pedal; calculating a first torque according to the first deceleration, wherein the first torque is a torque required for vehicle braking; and making the motor brake the vehicle based on the first torque. A vehicle deceleration process is completed through the accelerator pedal, a problem that the accelerator pedal and a brake pedal need to be frequently switched under a urban working condition is solved, driving fatigue is avoided, driving comfort is improved, energy consumption is reduced, and mechanical brake losses are decreased.

    本发明公开了一种基于油门踏板开度的制动方法及系统,所述方法包括以下步骤:当车辆处于预设工况时,获取车辆的状态信息,其中,状态信息包括车辆的档位信息、油门踏板的开度信息;当车辆处于预设档位时,根据油门踏板的开度信息,判断车辆是否满足第一预设条件;当车辆满足第一预设条件时,根据油门踏板的开度信息,计算第一减速度;根据第一减速度,计算第一扭矩,其中,第一扭矩为车辆制动所需的扭矩;基于第一扭矩控制电机以对车辆进行制动;本发明通过用油门踏板完成车辆减速过程,解决了在城市工况下需要频繁切换油门踏板和制动踏板的问题,避免了驾驶疲劳,提高了驾驶舒适性,降低能耗并减少机械制动损耗。
