【Abstract】 An assist regenerative braking system based on neural network was proposed to combine driving safety and braking energy recovery.An experiments-based fuzzy neural network of the vehicle braking was established to ensure driving safety.The look-up table of the regenerative and friction braking force was achieved through calculation.The fuzzy neural network and the look-up table were inserted in the braking system with a proportion valve to accomplish the assist regenerative braking system.The simulation results in Simulink have shown that the braking system can assist braking effectively,avoid rearend collision and can adequately recycle braking energy.更多还原
