Abstract
A control system for controlling a steering system is provided. The control system includes a first module that determines a position control value based on a handwheel position. A second module generates a torque command based on the position control value to simulate an end of travel stop in the steering system.
Claims16
A control system for controlling a steering system, the control system comprising:
- a first module that determines a position control value based on a handwheel position;
- and
- a second module that receives the position control value from the first module, and generates a torque command based on the position control value and a gain value to simulate an end of travel stop in the steering system, the gain value determined based on a comparison between the handwheel position and a range of position values representing an end of travel region.
A method of controlling a steering system, the method comprising:
- determining a position control value based on a handwheel position;
- determining a gain value;
- generating a torque command based on the position control value and the gain value to simulate an end of travel stop in the steering system;
- and
- determining a damping value, wherein the torque command is based on the damping value.
A method of controlling a steering system, the method comprising:
- determining a position control value based on a handwheel position;
- and
- generating a torque command based on the position control value to simulate an end of travel stop in the steering system, wherein the determining the position control value is based on a transmission range.
A control system for controlling a steering system, the control system comprising:
- a first module that determines a position control value based on a handwheel position;
- a second module that receives the position control value from the first module, and generates a torque command based on the position control value to simulate an end of travel stop in the steering system;
- and
- a third module that determines a damping value and the second module generates the torque command based on the damping value.
A method of controlling a steering system, the method comprising:
- determining a position control value based on a handwheel position;
- and
- generating a torque command based on the position control value to simulate an end of travel stop in the steering system, wherein the determining the position control value is based on a position error between the handwheel position and a range.
An electric power steering system for a vehicle, comprising:
- a handwheel position sensor;
- and
- a control module that receives a handwheel position from the handwheel position sensor and determines a position control value based on the handwheel position, and that generates a torque command to the electric power steering system based on the position control value to simulate an end of travel stop in the electric power steering system, wherein the control module determines a damping value and generates the torque command based on the damping value.
