University of Vigo

Description of the technology

To maximize the benefits of the implementation of new technologies in brake systems such as electromechanical brake actuators and a brake-by-wire system, it is necessary to count with slip controllers, since they will act as independent brake forces in each of the wheels. The application of reset controllers will lead to an improvement of the robustness and performance of the system. This improvement implies the reduction of the braking distance and a better tire and road friction maximum estimation.

Specifications

The wheel slip controller can be used for several high level control modules, such as antilock braking systems (ABS), anti-slip systems, traction control (TC), vehicle stability control (VSC), electronic stability protocol (ESP) and advanced driver assistance systems (ADAS), among others.

Main advantages of its use

  • The proposed wheel slip reset controller is a versatile controller with a simple design, that Improves performance and robustness simultaneously: - It decreases the braking distance while maintaining as far as possible the driving characteristics of the vehicle. - It prevents locks and unstable slips. - It is robust against changes in the road conditions and technological limitations such as model uncertainties, actuator saturation and bus time delay. - It improves the estimation of the maximum friction between tire and road

Applications

  • Industrial partners involved in technological advances in automotive, road and aeronautics vehicles.
