The invention provides an energy recycling method and an energy recycling device for a hybrid power supply electric automobile. The method comprises the following steps that the front and rear wheel braking force distribution strategy is carried out according to an I curve, an f curve and an ECE braking rule, and the front and rear wheel braking forces of the automobile are obtained according to the distribution strategy; the speed and braking strength of an automobile and the SOC of a super capacitor are obtained and input into a fuzzy controller, a membership function value of the fuzzy controller is optimized through a hybrid PSO algorithm, a new fuzzy controller is obtained, and the new fuzzy controller is substituted into the new fuzzy controller to obtain a regenerative braking forceproportion K; and the regenerative braking force of the motor is obtained according to the front and rear wheel braking forces and the K. According to the energy recycling method and the energy recycling device, the ECE braking rule is combined with the ideal braking distribution I curve and the f curve, and the membership function value of the fuzzy controller is optimized by adopting the hybridPSO algorithm so that the energy recycled by the motor can be greatly improved, the driving mileage is prolonged, the control is simple, and the implementation is easy.

    本发明提供一种复合电源电动汽车的能量回收方法、能量回收装置,其中,所述方法包括以下步骤:根据I曲线和f曲线和ECE制动法规进行前后轮制动力分配策略,并根据分配策获取汽车的前、后轮制动力;获取汽车的车速、制动强度和超级电容的SOC,并输入至模糊控制器中,采用混合PSO算法对模糊控制器隶属度函数值进行优化,得到新的模糊控制器,并将其代入新的模糊控制器以获取再生制动力比例K;根据前、后轮制动力和K获取电机再生制动力。本发明将ECE制动法规与理想制动分配I曲线以及f曲线相结合,并采用混合PSO算法对所述模糊控制器隶属度函数值进行优化,从而可以大大提高电机回收的能量,延长行驶里程,且控制简单、易于实施。
