Research on Predictive Cruise Control of Electric Vehicle Based on Time-Varying Model Prediction

Abstract

For the problem of ecological cruise control integrating the terrain information of the road ahead, in order to input the actual slope changed with time over the prediction horizon, a linear time-varying model predictive controller is designed in this paper based on the traditional theory of model predictive control. The analysis of vehicle driving on flat road and hilly road is simulated by MATLAB/Simulink, results show that it has a good effect on energy saving at the cost of shorter distance. In addition, the energy consumption under different control targets and the influence of weight coefficients on vehicle economy under the same target are also analyzed and compared.
