This paper describes the design and evaluation of an integrated control strategy for longitudinal safety and lateral stability. The objective of the integrated control strategy is to optimally coordinate independent brake inputs for longitudinal collisionsafety and lateral stability in various driving situations such as lane change with braking and circular turning with braking, etc. The proposed integrated vehicle safety system is applied to the vehicle equipped with Smart Cruise Control (SCC)/Collision Avoidance (CA) and Vehicle Stability Control (VSC). The proposed control system consists of a supervisor, control algorithms, and a coordinator. The proposed system has three control modes which are normal driving, integrated safety I, and integrated safety II. According to the corresponding control mode, the longitudinal and lateral control algorithms calculate the desired motion of the subject vehicle. Based on the desired longitudinal force and the desired yaw moment, the coordinator determines the throttle angle and the brake pressures by using optimal distribution. Closed-loop simulations with the driver-vehiclecontroller system are conducted to investigate the performance of the proposed integrated vehicle safety system. Finally, the proposed control system was also implemented in a sport utility vehicle and tested in several driving situations.
