Regenerative Braking Control Method Based on Predictive Optimization for Four-Wheel Drive Pure Electric Vehicle

Regenerative braking is the key to achieve efficient use of energy and extend driving range in pure electric vehicles. This study proposes a new predictive control method integrating adaptive cubic exponential prediction dynamic programming address problem recovery during regular process four-wheel The considers characteristics an electro-hydraulic combined system. adopted predict vehicle velocity intensity. employed optimize motor torques wheel cylinder pressures under condition regulations, road constraints, constraints. To verify effectiveness method, ideal multi-stage force distribution methods are for comparison. results confirm that, gradual conditions, efficiency achieved via proposed improved by 1.55% 6.40% considering methods, respectively.
