【Abstract】 Based on the analysis of relation of regenerative braking efficiency and motor,battery as well as CVT efficiency,an optimal working line of motor,battery and CVT was obtained and an optimal control strategy of regenerative braking was proposed in which the efficiencies of the motor,battery and CVT are taken into account.The regenerative braking model of HEV was established and the simulation was carried out.The results showed that compared to the current control strategy for regenerative braking of HEV;the proposed control strategy can not only ensured the prerequisite of braking safety,but also further improved the recovery of braking energy.更多还原
