Methods and systems for controlling steering response and steering torque feedback based on steering position
First Claim
1. A method of controlling nominal vehicle steering characteristics in a vehicle steering system, comprising:
- determining an actual position of an adjustable steering wheel and/or steering column of the vehicle;
comparing the actual position to a reference position of the steering wheel and/or steering column; and
based at least in part on the comparison, adjusting at least one of a steering ratio and a steering torque feedback in the vehicle steering system.

Abstract
Arrangements (e.g., method; vehicle; non-transitory, tangible, machine-readable media embodying a program) for controlling nominal vehicle steering characteristics in a vehicle steering system are disclosed. A method of controlling nominal vehicle steering characteristics includes determining an actual position of an adjustable steering component of the vehicle, comparing the actual position to a reference position of the component, and based at least in part on the comparison, adjusting at least one of the steering ratio and a steering torque feedback in the vehicle steering system. In one embodiment, based at least in part on the comparison, a percentage of change in a steering ratio for a range of steering wheel angles is calculated and, based on the percentage of change, at least one of the steering ratio and a steering torque feedback in the vehicle steering system is adjusted to a nominal value associated with the nominal vehicle steering characteristics.
