%X A high-performance longitudinal acceleration control is a crucial technology for the advanced vehicle dynamics and the active safety-system. However, its practical realization is still with difficulties because of the strong nonlinearity and uncertainty in the vehicle acceleration system. For this reason, a new acceleration control approach based on the active disturbance-rejection control(ADRC) is proposed. First, a dynamic model of the vehicle longitudinal locomotion is built and the engine-brake cooperation strategy for the acceleration control is designed. Next, a two-subsystem affine dynamic model is developed for the engine-vehicle acceleration model and the brake-vehicle acceleration model. Two correspondent controllers based on the linear discrete ADRC algorithm are designed. Finally, simulations are carried out to validate the new approach. The results show that the rapid response and high-precision performances can be achieved simultaneously in the vehicle longitudinal acceleration control.
