چکیده
Abstract When EV failure happens, it needs to take some fault-tolerant method to ensure people’s safety. When the current sensor and speed sensor are out of work, the software fault-tolerant control algorithm switching strategy can be used. This paper has done theoretical analysis of the rotor field-oriented vector control algorithm into the open loop constant V/F control algorithm, and the phase angle compensation method is used to reduce the shock of current and torque, and simulation is done in MATLAB/Simulink.

Design of Fault Tolerant Control System for Electric Vehicles with Steer-by-Wire and In-Wheel Motors
In this paper we propose a fault tolerant control method which is capable of mitigating steering and drive-train system failures. By utilizing the steering system and the drive-train system complementarily, the proposed method will not need an additional redundancy for the fault tolerant purpose. For the steering system failure which should be detected and managed rapidly, the proposed method u...
متن کاملFailsafe Control Methods for EVs with the Failsafe Structure Driven by Front and Rear Wheels Independently
This paper describes failsafe control methods for electric vehicles (EVs) with the failsafe structure in which front and rear wheels are driven independently. Based on failure-diagnosis results, the failsafe control is done by dividing fault states into two types, i.e. a slight failure such as a current or a speed sensor failure and a serious failure such as an inverter or a motor failure. For ...
