The invention relates to a hybrid commercial vehicle braking mode intelligent management method. The intelligent management method comprises the following steps: continuously monitoring and acquiringa brake pedal opening signal; judging whether the vehicle is in a deceleration braking state or not according to the brake pedal opening signal; if the vehicle is in the deceleration braking state, calculating a required braking torque of the whole vehicle; calculating the maximum braking torque which can be provided by a hybrid motor at the current moment; collecting a vehicle speed at the current moment; calculating a rotating speed of the hybrid motor according to the vehicle speed at the current moment; comparing the rotating speed of the hybrid motor with the minimum starting rotating speed of the hybrid motor, and judging a braking mode adopted at the current moment according to a comparison result; and comparing the required braking torque and the maximum braking torque, and determining the braking mode adopted at the current moment according to a comparison result. In the invention, the hybrid motor is incorporated into the braking system so that the braking energy recovery andmanagement of the hybrid commercial vehicle based on EBS are realized.

    本发明涉及混动商用车制动方式智能管理方法,包含步骤:持续监测并采集制动踏板开度信号;根据制动踏板开度信号判断车辆是否处于减速制动状态;如果车辆处于减速制动状态,则计算整车的需求制动扭矩;计算混动电机在当前时刻可以提供的最大制动扭矩;采集当前时刻的车速;然后通过当前时刻的车速计算混动电机转速;比较混动电机转速与混动电机最小启动转速的大小,并根据比较结果判定当前时刻采用的制动方式;比较需求制动扭矩和最大制动扭矩的大小,并根据比较结果判定当前时刻采用的制动方式。本发明通过将混动电机纳入制动系统,从而实现基于EBS的混动商用车制动能量回收及管理。
