The intelligent trend of vehicles became irresistible,and the application of adaptive cruise control systems to different vehicles,especially to electric vehicles,became a trend.The application of adaptive cruise control systems played a significant role in environmental protection,road traffic efficiency and safety.In this paper,we proposed a hierarchical controller for the adaptive cruise system of the electric bus.Based on millimeter-wave radar,target tracking and recognition algorithms for straight and curved conditions hadbeen performed.In the upper controller,a proportional differential control algorithm hadbeen adopted based on the vehicle spacing with variable time-headway and its stability hadbeen proved.In the lower level controller,the look-up table for acceleration and braking hadbeen designed based on test data and a switching rule for acceleration and braking hadbeen formulated.The results of off-line simulation and hardware-in-the-loop simulation showed that the adaptive cruise controller designed with mature control strategy can achieve faster and more accurate control response,real-time performance,and was suitable for applicationon real vehicles.
