Abstract
An electronic control system may be used to control the steering angle of a vehicle wheel. The electronic control system may be used to determine that a measured speed that a steering angle of a wheel is changing exceeds a threshold speed. The electronic control system may be used to determine that a measured range of motion of the steering angle exceeds a threshold amount. The electronic control system may use an encoder to measure the position of a steering angle of a vehicle wheel.
Claims25
An electronic control system for a vehicle comprising:
- a sensor that provides information relating to a steering angle of a front vehicle wheel;
- wherein the electronic control system uses the information provided by the sensor to determine whether a measured speed at which the steering angle of the front vehicle wheel is changing exceeds a steering relationship deadband;
- and
- wherein the electronic control system is configured to turn a rear wheel in relation to the front wheel based on a steering relationship deadband determination.
An electronic control system for a vehicle comprising:
- a sensor that provides information relating to a steering angle of a vehicle wheel;
- wherein the electronic control system uses the information provided by the sensor to determine whether a measured range of motion of the steering angle exceeds a threshold amount and wherein the threshold amount is based on normal vehicle operations;
- and
- wherein normal vehicle operations are a vehicle operating condition that conforms to a predetermined vehicle operating condition.
An electronic control system for a vehicle comprising:
- an encoder that provides information relating to a steering angle of a first vehicle drive wheel;
- an actuator capable of adjusting a steering angle of a second vehicle drive wheel;
- wherein the electronic control system uses the actuator to adjust the steering angle of the second vehicle drive wheel based on the information provided by the encoder;
- and
- wherein a learning module is configured to calculate a threshold value required to operate a cylinder.
An electronic control system for a vehicle comprising:
- a sensor that provides information relating to a steering angle of a vehicle wheel;
- wherein the electronic control system uses the information provided by the sensor to determine whether a measured speed at which the steering angle is changing exceeds a steering relationship deadband;
- wherein the electronic control system is configured to turn a rear wheel in relation to a front wheel based on a steering relationship deadband determination;
- wherein a learning logic is configured to adjust a threshold value required to operate a cylinder based on at least one of a hydraulic fluid temperature and a vehicle weight;
- and
- wherein the learning logic adjusts the threshold value based on at least one of a first difference between a first hydraulic fluid temperature and a second hydraulic fluid temperature and a second difference between a first vehicle weight and a second vehicle weight.
