A control system for operating an air vehicle for urban air mobility (UAM) is arranged such that when a steering operation for a steering wheel and a stroke operation for an accelerator pedal and a brake pedal are performed for operating the air vehicle for UAM, haptic feedback providing notification of any operational limitations is provided to a driver, so that operation stability and convenience of the driver are secured and stable steering, acceleration, and deceleration of the air vehicle are performed.

Control system for operating air vehicle for urban air mobility

A motor driven power steering system includes: a power source for generating a steering assistance force assisting the steering of a vehicle; a transfer gear positioned between a power source and a column for transferring the steering assistance force generated by the power source to the column; a parameter estimation unit for estimating a friction parameter of a dynamic friction model based on the actual friction torque actually generated in the transfer gear; and a state estimation unit for calculating a state variable of the dynamic friction model based on a contact surface moving speed of the transfer gear and for estimating expected friction torque according to the dynamic friction model by using the calculated state variable and the friction parameter of the dynamic friction model estimated by the parameter estimation unit.

A system and method for detecting a hands-off state of a steering wheel may include acquiring, by a controller, a steering torque, a steering angle and a steering angular speed while driving of a vehicle, determining, by the controller, a variance value of the steering angular speed through cumulation for a designated time, determining, by the controller, a difference value between a steering angular speed estimated through a steering system model determined on an assumption that the steering wheel is in the hands-off state and a measured steering angular speed through cumulation for a designated time, when the variance value of the steering angular speed is less than a first threshold value, and divisionally determining, by the controller, whether or not the steering wheel is in the hands-off state or in the hands-on state according to the difference value between the measured and estimated steering angular speeds.
