Steering-wheel control
First Claim
1. A controller comprising a processor and a memory in a vehicle including a steering wheel, a steering-wheel actuator coupled to the steering wheel, and a road wheel, the controller programmed to:
- determine a steering-wheel angle based on a road-wheel angle of the road wheel from a sensor of the vehicle, an operation mode of the vehicle stored in the memory, and a steering-compensation type of the vehicle stored in the memory, wherein the operation mode includes a nonautonomous mode having a default steering ratio and at least one autonomous mode;
instruct the steering-wheel actuator to rotate the steering wheel according to the steering-wheel angle,determine that the operation mode is the nonautonomous mode; and
upon determining that the operation mode is the nonautonomous mode, instruct the steering-wheel actuator to rotate the steering wheel to a default steering-wheel angle that is the default steering ratio multiplied by the road-wheel angle.

Abstract
A vehicle includes a steering wheel and at least one road wheel. The steering wheel is rotatably connected to a steering-wheel actuator, and the at least one road wheel is movably connected to a steering system. A controller is in communication with the steering system and the steering-wheel actuator. The controller is programmed to determine a steering-wheel angle based on a road-wheel angle, an operation mode, and a steering-compensation type; and to instruct the steering-wheel actuator to rotate the steering wheel according to the steering-wheel angle.

10. A method of steering a vehicle comprising:
-
determining, by a controller of the vehicle, a steering-wheel angle based on a road-wheel angle of a road wheel of the vehicle from a sensor of the vehicle, an operation mode of the vehicle stored by the controller, and a steering-compensation type of the vehicle stored by the controller, wherein the operation mode includes a nonautonomous mode having a default steering ratio and at least one autonomous mode; instructing, by the controller, a steering-wheel actuator coupled to a steering wheel of the vehicle to rotate the steering wheel according to the steering-wheel angle, determining, by the controller, that the operation mode is the nonautonomous mode, and upon determining that the operation mode is the nonautonomous mode, instructing, by the controller, the steering-wheel actuator to rotate the steering wheel to a default steering-wheel angle that is the default steering ratio multiplied by the road-wheel angle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
