Abstract
The present invention provides a steering system for an in-wheel motor vehicle capable of controlling driving torques and speeds of in-wheel motors mounted in left and right wheels to be different from each other at the time of curve driving of the vehicle to generate a steering angle of the wheel for the curve driving, and performing a steering angle control of sensing the generated steering angle and fixing the steering angle to a desired steering angle.
Claims19
A steering system for an in-wheel motor vehicle, the steering system comprising:
- a steering wheel steering angle sensor configured to sense a steering angle of a steering wheel;
- a controller configured to control driving speeds of in-wheel motors mounted at left and right wheels to be different from each other according to the steering angle of the steering wheel sensed by the steering wheel steering angle sensor;
- and
- a steering control module configured to sense a steering angle of left and right wheels generated due to a difference between speeds of the left and right wheels resulting from the difference between the driving speeds of the in-wheel motors and to adjust the steering angle of the left and right wheels to a steering angle corresponding to the steering angle of the steering wheel by a steering angle adjustment signal of the controller.
A vehicle comprising:
- a vehicle body;
- a steering wheel within the vehicle body;
- a steering wheel steering angle sensor configured to sense a steering angle of the steering wheel;
- left and right wheels attached to the vehicle body;
- a first in-wheel motor mounted at the left wheel;
- a second in-wheel motor mounted at the right wheel;
- a controller configured to control driving speeds of the first and second in-wheel motors to be different from each other according to the steering angle of the steering wheel sensed by the steering wheel steering angle sensor;
- and
- a steering control module configured to sense a steering angle of the left and right wheels generated due to a difference between speeds of the left and right wheels resulting from the difference between the driving speeds of the first and second in-wheel motors and to adjust the steering angle of the left and right wheels to a steering angle corresponding to the steering angle of the steering wheel by a steering angle adjustment signal of the controller.
A method of operating an in-wheel motor vehicle, the method comprising:
- sensing a steering angle of a steering wheel;
- controlling driving speeds of in-wheel motors mounted at left and right wheels of the vehicle to be different from each other according to the sensed steering angle of the steering wheel;
- sensing a steering angle of the left and right wheels generated due to a difference between speeds of the left and right wheels resulting from the difference between the driving speeds of the in-wheel motors;
- and
- adjusting the steering angle of the left and right wheels to a steering angle corresponding to the steering angle of the steering wheel.
