Abstract
In some examples, a vehicle includes a steering system having a user-operated steering control configured to steer the vehicle. The vehicle includes a controller independent of the steering system and configured to receive an indication that the steering system employs dynamic steering angle ratio adjustment of the steering control, and modify an operation of the controller based on the indication.
Claims18
A vehicle comprising:
- a steering system comprising a user-operated steering control configured to steer the vehicle;
- and
- a controller independent of the steering system and configured to:
- receive an indication that the steering system employs dynamic steering angle ratio adjustment of the steering control, and
- modify an operation of the controller based on the indication,
- wherein the steering system is configured to apply dynamic steering angle ratio adjustment of the steering control by adjusting, based on input information, a relationship between a displacement of the steering control and a corresponding pivoting of vehicle wheels of the vehicle, and wherein the input information comprises one or more selected from among:
- a speed of the vehicle, an acceleration of the vehicle, a location of the vehicle, a torque of an engine of the vehicle, a driver preference, a level of experience of a driver, or an operating condition.
4 more elements
A non-transitory machine-readable storage medium comprising instructions that upon execution cause a system to:
- receive an indication that a steering system of a vehicle employs dynamic steering angle ratio adjustment of a steering control of the steering system;
- and
- modify a non-steering operation for the vehicle based on the indication,
- wherein the steering system is configured to apply dynamic steering angle ratio adjustment of the steering control by adjusting, based on input information, a relationship between a displacement of the steering control and a corresponding pivoting of vehicle wheels of the vehicle, and wherein the input information comprises one or more selected from among:
- a speed of the vehicle, an acceleration of the vehicle, a location of the vehicle, a torque of an engine of the vehicle, a driver preference, a level of experience of a driver, or an operating condition.
2 more elements
A method of a system comprising a hardware processor, comprising:
- receiving, at the system, an indication that a steering system of a vehicle employs dynamic steering angle ratio adjustment of a steering control of the steering system;
- and
- modifying, by the system based on the indication, an output produced by software that is independent of the steering system,
- wherein the indication comprises an indicator set to a first state, and wherein the software produces the output based on a displacement of the steering control and a steering angle ratio in response to the indicator being set to the first state, and wherein the software produces an output based on a displacement of the steering control uncompensated by a steering angle ratio in response to the indicator being set to a second state different from the first state.
