Road type detection based on impulsive observer with synchronous and asynchronous measurements

An impulsive observer with synchronous and asynchronous measurements is investigated in this work. To prove the efficiency of this observer a simplified quarter vehicle model is used. This observer is designed to estimate the wheel slip ratio parameter λ by two measurements in the case of ABS brake systems. These measurements are the wheel rotation speed and the vehicle speed. Simulation results highlight the efficiency of the proposed impulsive observer.
