Design of vehicle cruise control using road inclinations

Abstract

The paper proposes the design of velocity based on road inclinations, speed limits, a preceding vehicle on the lane and traveling time. A new control method in which the longitudinal control incorporates the brake and traction forces is also proposed to achieve the required velocity. By choosing the velocity which is appropriate according to the road and traffic information, the number of unnecessary accelerations and brakings and their durations can be significantly reduced. In the design method the modelling and robust control of the Linear Parameter Varying (LPV) theory are exploited. The operation of the longitudinal controlled system and the influences of different designed parameters are analysed through vehicle simulations. Finally, the efficiency of the controlled system is demonstrated on a real transportation route.
