This paper aims to control roll, pitch and vertical displacement of the suspended mass in a passenger vehicle during on-road drive by means of controlling the active suspension system. One of the goals of this control is to isolate the suspended mass in the vehicle from any road perturbation to ensure a big amount of comfort to the passengers (less roll, less pitch and less vibrations). Two strategies...
The aim of the presented work is to estimate the vertical forces of heavy vehicle and identify the unknown dynamic parameters using sliding mode observers approach. The vertical forces are then considered as perturbation to be identified. The observation needs a good knowledge of some dynamic parameters such as damping coefficient, spring stiffness…etc. In this paper, some of these parameters, namely...
In this paper, the deployment of a fault diagnosis strategy in the Smart Distance Keeping (SDK) system with a decentralized architecture is presented. The SDK system is an advanced version of the Adaptive Cruise Control (ACC) system, implemented in a Renault-Volvo Trucks vehicle. The main goal of this work is to analyze measurements, issued from the SDK elements, in order to detect, to localize and...
This paper presents a detailed description of an advanced Adaptive Cruise Control (ACC) system implemented on a Renault-Volvo trucks vehicle. One of the main differences between this new system, which is called the Smart Distance Keeping (SDK), and the classical ACC is the choice of the safe distance. This later is the distance between the vehicle (with the ACC or the SDK system) and the front obstacle...
In this paper, tires longitudinal forces, vehicle side slip angle and velocity are identified and estimated using sliding modes (SM) observers. Longitudinal forces are estimated using high order SM observers, while for the estimation of the vehicle side slip angle and vehicle velocity, a SM observer based on the hierarchical super twisting algorithm. Validations with the simulator VE-DYNA pointed...
In this paper, sliding mode (SM) observers are proposed to replace expensive sensors used for the measurement of tires forces, vehicle side slip angle and vehicle velocity. These estimations are done for two important purposes: The first is for the estimation of the forces and parameters needed for vehicle control, while the second is for the diagnosis preview based on the safety region for each parameter...
In the presented paper, the tire pressure and its influence on the vehicle centre of gravity are estimated and analysed. For that reason, a relation relating the tire pressure to the vertical force and the tire vertical deflection is proposed and validated by real measures. Basing on this proposed model, the tire pressure estimation is realized by estimating the vertical force and the tire vertical...
