Abstract
The disclosure generally relates to steer-by-wire steering systems and, more particularly, to methods and apparatus for a steer-by-wire (SBW) steering system. An example a vehicle comprising a hand wheel actuator, a road wheel actuator, and a steering controller to instantiate or execute machine readable instructions to determine a speed of a steering input to the hand wheel actuator, determine an acceleration of the steering input, and in response to the acceleration being a deceleration larger than a first threshold and the speed being below a second threshold, apply a gradient torque limit to the road wheel actuator.
Claims20
A vehicle comprising a hand wheel actuator;
- a road wheel actuator;
- and a steering controller to instantiate or execute machine readable instructions to:
- determine a speed of a steering input to the hand wheel actuator;
- determine an acceleration of the steering input;
- and in response to the acceleration being a deceleration larger than a first threshold and the speed being below a second threshold, apply a gradient torque limit to the road wheel actuator.
A non-transitory computer readable storage medium comprising instructions to cause programmable circuitry to at least:
- determine a speed of a steering input to a hand wheel actuator of a vehicle;
- determine an acceleration of the steering input;
- and in response to the acceleration being a deceleration larger than a first threshold and the speed being below a second threshold, apply a gradient torque limit to a road wheel actuator of the vehicle.
A method comprising:
- determining a speed of a steering input to a hand wheel actuator of a vehicle;
- determining an acceleration of the steering input;
- and in response to the acceleration being a deceleration larger than a first threshold and the speed being below a second threshold, applying a gradient torque limit to a road wheel actuator of the vehicle.
