The invention relates to a braking energy recovery control method, a computer storage medium and a new energy commercial vehicle, and the method comprises the following steps: calculating the real-time load mass of the vehicle, calculating the dynamic load of a front axle and a rear axle, obtaining the relation between the dynamic torque of the front axle and the rear axle and the opening degree of a pedal, and obtaining the braking torque Tf and Tr1 of the front axle and the rear axle under different pressures; the relation between the sliding resistance a and the sliding resistance V is obtained, the maximum rear wheel braking torque Tr is calculated, the braking torque Tr1 of a rear axle and the maximum rear wheel braking torque Tr are obtained, and the braking torque of maximum energy recovery is obtained. The method has the advantages that on the premise of guaranteeing braking stability, the maximum rear wheel braking torque Tr is calculated through the relation between the braking strength and the rear wheel utilization rate, the braking torque Tr1 of a rear axle and the maximum rear wheel braking torque Tr are obtained, and the braking torque Tre of maximum energy recovery is obtained; the energy recovery efficiency of the new energy commercial vehicle can be effectively improved, and the braking stability in the energy recovery process is guaranteed.

    本发明涉及一种制动能量回收控制方法、计算机存储介质及新能源商用车,包括以下步骤:计算出车辆实时载荷质量,计算出前轴和后轴动的态载荷,得出前桥和后桥制的动扭矩与踏板开度的关系,得到不同压力的前桥和后桥的制动扭矩Tf与Tr1,得出滑行阻力a与V的关系,计算出最大的后轮制动扭矩Tr,得到后桥的制动扭矩Tr1以及最大的后轮制动扭矩Tr,得出最大能量回收的制动扭矩。其优点在于:保障制动稳定的前提下,通过制动强度与后轮利用率的关系计算出最大的后轮制动扭矩Tr,得到后桥的制动扭矩Tr1以及最大的后轮制动扭矩Tr,得出最大能量回收的制动扭矩Tre;可有效提升新能源商用车的能量回收效率并保证能量回收过程中制动的稳定性。
