Development of an LQ regulator for longitudinal vehcile control of an automated vehicle

Nowadays in road transport lower fuel consumption, higher traffic safety and reduced environmental impact are in the focus of the developments. To reach these future objectives it is necessary to increase the level of automation of road vehicles. Driving a road vehicle by a software is a complex controlling task. This paper presents a basic longitudinal motion controller, which uses a Linear-Quadratic (LQ) regulator. This controller is widespread in the controlling of MIMO systems, because it provides an interactive control, optimized for certain elements of the state vector. The aim of this work is to create an operative longitudinal vehicle control based on an LQ regulator and use it in a demonstration vehicle.
