Abstract
A hands-off state detection method of a vehicle includes determining a difference between a pinion angle and a column angle of a motor-driven power steering (MDPS) system of the vehicle, and determining a hands-off state of a steering wheel of the vehicle based on the difference between the pinion angle and the column angle.
Claims12
A hands-off state detection method of a vehicle comprising:
- determining a difference between a pinion angle and a column angle of a motor-driven power steering (MDPS) system of the vehicle;
- determining whether a state of a steering wheel of the vehicle is a hands-off state based on the difference between the pinion angle and the column angle, the hands-off state indicating that hands of a driver of the vehicle are spaced apart from the steering wheel;
- and
- controlling the vehicle based on the determining of the hands-off state.
1 more element
A vehicle comprising:
- a torque angle sensor provided to detect a difference between a pinion angle and a column angle of a motor-driven power steering (MDPS) system of the vehicle;
- and
- an electronic controller configured to:
- determine the difference between the pinion angle and the column angle of the motor-driven power steering (MDPS) system, and
- determine whether a state of a steering wheel of the vehicle is a hands-off state based on the difference between the pinion angle and the column angle, the hands-off state indicating that hands of a driver of the vehicle are spaced apart from the steering wheel.
