Vehicle Active Safety

Vehicle stop and go frequently can cause driver fatigue, even traffic accidents. In order to mitigate driver fatigue and the risk of rear-end collision accidents, a set of hierarchical vehicle stop and go cruise control system(S&G) was established. A vehicle dynamics model was created with Carsim, the determination of safety distance was based on headway method. Then upper controller and lower controller were designed separately based on optimal control and fuzzy PID control principle. Finally, a simulation loop was built in Simulink. Through a co-simulation conducted under typical S&G driving condition, got speed change curves,acceleration change curves and relative distance change curves of host vehicle while following the target vehicle. The results show that the S&G system designed can make host vehicle well follow the speed change of leading vehicle while keeping an appropriate safety distance, stop and go automatically, reduce driver fatigue and improve vehicle active safety.

While adaptive cruise control (ACC) systems have been broadly few studies have investigated the user experience characteristics of recent production systems. The present study was designed for the express purpose of testing one such system. Nineteen participants drove a 2014 BMW X-5 M, equipped with adaptive cruise control, in two scenarios designed to be representative of the usage scenarios described by the vehicle manufacturer. During testing, user interactions with the system were recorded while opinions regarding the usability and operation of the system were elicited through a series of interviews and questionnaires. While participants responded favorably to the system conceptually, participants expressed considerable dissatisfaction with the ACC’s braking behavior and with specific aspects of the system’s user interface. These findings add to a growing body of research that suggests that mode confusion or insufficient awareness of system status may be a significant impediment to the use of ACC systems generally.

Implementation and vehicle tests of a vehicle longitudinal control algorithm for stop-and-go cruise control have been performed. The vehicle longitudinal control scheme consists of a set-speed control algorithm, a speed control algorithm, and a distance control algorithm. A desired acceleration for the vehicle for the control of vehicle-to-vehicle relative speed and clearance has been designed using linear quadratic optimal control theory. Performance of the control algorithm has been investigated via vehicle tests. Vehicle tests have been conducted using two test vehicles. A 2000 cm3 passenger car equipped with a radar distance sensor, throttle/brake actuators and a controller has been used as a subject vehicle in the vehicle tests. A millimetre wave radar sensor has been used for distance measurement. A step motor and an electronic vacuum booster have been used for throttle/brake actuators. It has been shown that the implemented vehicle longitudinal control system can provide satisfactory performance in vehicle set-speed control and vehicle clearance control at lower speeds.
