In this paper we explore the dynamics of a single-track car model. We develop a model of a rigid car inspired to the well known bicycle model. The bicycle model is a planar rigid model that approximates the vehicle as a rigid body with two wheels. However, the bicycle model does not allow to describe the effect of load transfer, since it does not model the suspensions. Using an explicit formulation...
This paper presents a 9-degree of freedom (DOF) vehicle model combined with a closed loop driver model for the purpose of developing vehicle lateral control. The driver model was developed to control the steering angle and uses the lookup table path as a reference for the control input. The proposed outer-loop controller structure for the driver model is a combination of proportional gain control...
Anti-lock and also Anti-slip braking system controller designed for stability enhancement of vehicle during braking and turning circumstances is presented. Using available signals, a novel structure is proposed for vehicle stability improvement encountering critical braking conditions such as braking on slippery or μ-split road surfaces. In conventional vehicles, undesired lane changes may occur due...
In this paper, a new active suspension control scheme is proposed in which the tire deflections are not required. The controller has good property that we can specify a location where the ride comfort becomes best. To achieve this end, a combined ideal vehicle is designed. In the ideal vehicle, the location where ride comfort becomes best can be moved by setting only one design parameter. Next, to...
For a fully automation ground vehicle, the accurate longitudinal speed becomes more and more important due to the increasing demands on tracking of position, velocity and acceleration. Based on low-cost wheel speed encoders, this paper proposes a novel longitudinal speed estimator for vehicles on cornering maneuver. In the estimator, a gain-varying Kalman estimator is designed to output lateral states...
Direct yaw moment control generated by differential friction forces on an axle has been proved to be effective in improving vehicle lateral yaw stability and in enhancing handling performance. It consists of two levels of control tasks: calculating a yaw moment command at vehicle level and regulating the tire slip to deliver the moment at wheel level. Advanced powertrain with electrical in-wheel-motor...
According to traffic accident data, the majority of severe road accidents occur at night. It is, therefore, of great importance to use available technology to contribute to road safety by improving the visual conditions provided by vehicle headlights. This paper presents the hardware in the loop simulation of an adaptive headlight system for motor vehicles. The adaptive headlight system is an active...
