To optimize fuel economy and improve vehicle longitudinal control performance, this paper proposed a speed & gear planning strategy considering traffic light information and velocity tracking control. First, to guarantee that the vehicle can pass through traffic lights without stop if possible and retain the highest terminal speed, this article discusses a Propelling or Coasting (PoC) serialization scheme. The speed & gear planning are realized by adjusting acceleration while propelling, with the upper and lower speeds set according to vehicle status and traffic light information; Second, to improve the accuracy and anti-perturbation performance of longitudinal control, a compound control method using improved Global Fast Terminal Sliding Mode Control (GFT-SMC) is developed, which enables the reduction of control output while maintaining high tracking performance and smooth control ability. Finally, both the hardware-in-loop (HIL) and real-vehicle experimental results show that the proposed control method effectively improves fuel economy with better speed tracking performance and strong perturbation robustness.
