2results about How to "With steering function" patented technology

The application discloses a kind of steer-by-wire device fault-tolerant reconstruction methods, steer-by-wire device includes steering road feel executor, steer-by-wire executor and corresponding fault-tolerant reconstruction controller, corresponding fault-tolerant reconstruction controller includes steering monitoring unit, fault diagnosis unit and fault-tolerant reconstruction unit, steering monitoring unit is used to monitor the working parameter of steering execution motor in steer-by-wire device, fault diagnosis unit is used to determine the fault state of steer-by-wire device according to working parameter and identifies fault type, fault-tolerant reconstruction unit is used to when the fault of steer-by-wire device occurs, the working state of steering execution motor is switched to fault maintenance mode, to maintain the steering function of steer-by-wire device. According to working parameter, identify the fault type, when failure occurs, single three-phase motor limp control, position sensor reconstruction control and current sensor reconstruction control are carried out to steering execution motor, to ensure that steer-by-wire device still has certain steering control function under certain fault.
