Abstract
A method for estimating steering assistance provided by a power steering system of a vehicle may include correlating an internal torque applied by an adaptive steering system of the vehicle with an external torque applied to a steering assembly of the vehicle. The method may also include estimating the steering assistance based on the correlation.
Claims25
A method for estimating steering assistance provided by a power steering system of a vehicle, comprising:
- with a controller of the vehicle:
- correlating an internal torque applied to a steering assembly of the vehicle by an adaptive steering system of the vehicle with an external torque applied to the steering assembly by an external source;
- and
- estimating the steering assistance provided by the power steering system based on the correlation.
A method of compensating for a change in steering assistance provided by a power steering system of a vehicle, comprising:
- determining, with a controller of the vehicle, an external torque applied to a steering assembly of the vehicle by an external source;
- measuring, with a sensor communicatively coupled to the controller, an internal torque applied to the steering assembly by an adaptive steering system of the vehicle;
- and
- correlating the external torque with the internal torque with the controller;
- estimating a change in the steering assistance provided by the power steering system based on the correlation;
- and
- adjusting the adaptive steering system based on the change.
A system for estimating steering assistance provided by a power steering system of a vehicle, comprising:
- a sensor configured to measure an internal torque applied to a steering assembly of the vehicle by an adaptive steering system of the vehicle;
- and
- an adaptive steering controller communicatively coupled to the sensor,
- wherein the adaptive steering controller is configured to correlate the internal torque with an external torque that is applied to the steering assembly by an external source and estimate the steering assistance provided by the power steering system based on the correlation.
