The main purpose of this paper concerns a fault tolerant control applied on an electric vehicle known as RobuCar which is a 4times4 electric vehicle, with four electromechanical wheel systems. Fault tolerant control (FTC) is attended to continue the system operation in the presence of several faults in order to remain the security of the system. Active fault tolerant control (AFTC) approach needs fault detection and isolation (FDI) algorithm to detect and identify the fault with minimum false alarm, missed alarm and time delay ... Only healthy components are used to reconfigure the control law of the system. RobuCar is particularly adapted to receive a fault tolerant module since it is composed of redundant components.
