In this paper, a braking force distribution strategy based on braking strength is proposed, which could improve the braking stability and at the same time maximize the energy recovery as well. Firstly, to determine the distribution area of the front and rear axle braking forces. we analyse the vehicle braking dynamics model and the relevant laws and regulations under the premise of ensuring the stability of the vehicle, Secondly, the optimal braking force distribution curve is determined base on the braking strength according to the characteristics of the motor and other constraints, which makes the energy recovery efficiency. Finally, the proposed algorithm is applied to the MATLAB"s electric vehicle simulation software, and the simulation is carried out under the four typical urban road cycle conditions, And the experimental results are compared with the original algorithm which is in the electric vehicle simulation software, The results show that the control strategy proposed in this paper can make the automobile recycle more energy in the braking process under the premise of ensuring the vehicle braking stability.
