Sliding Mode Control for Longitudinal Control of a Platoon of Adaptive Cruise Control Vehicles

Abstract

Automotive vehicle following systems are essential for the design of automated highway system. Vehicles equipped with adaptive cruise control system can operate on automated highway system during the vehicle following mode. This paper presents the sliding model control algorithm for the longitudinal control of a platoon of adaptive cruise control vehicles in the presence of noise signal and investigates the performance of platoon under the influence of sudden acceleration. This model has been applied on 3 vehicles moving in a platoon. The platoon has been analysed to retain the uniform velocity and safe spacing among the vehicles. Two different vehicle longitudinal models have been analysed and the simulation results obtained from them have been compared. Sliding mode control method is found suitable for the automotive vehicle following. Model simulations, in comparison with the literature, are also presented
