Research on adaptive cruise control algorithm considering road conditions

Abstract

As one of the most important ADAS systems, traditional adaptive cruise control is only suitable for relatively simple working conditions such as expressways, and it is difficult to deal with complex traffic environment and road working conditions. For the problem that the traditional cruise control strategy cannot effectively use the terrain to reduce vehicle fuel consumption under slope conditions and when the vehicle enters a small radius curve such as a ramp, the excessively high turning speed will cause the vehicle to skid. This paper proposes an adaptive cruise control system architecture with adaptability to multiple operating conditions. Simulation and real-vehicle test results show that the adaptive control system architecture and optimisation algorithm proposed in this paper have good applicability to road conditions, and improve the economy of the system under ramp conditions and safety under curve conditions.
