Abstract
Embodiments discussed herein enable detection of traction steer using measured and expected values of steering system data, such as, for example and without limitation, motor current, motor torque, motor position, motor velocity, steering wheel angle, and steering column torque. In some embodiments, the measured steering system data is compared to expected signal values, based on vehicle operating conditions, to determine if the vehicle is experiencing a traction steer event. In some embodiments, using known relationships between two or more steering system signals, a traction steer event is identified if an unexpected relationship is determined.
Claims17
A method for detection of a traction steer event, comprising:
- receiving steering system data from one or more vehicle sensors;
- determining a current operating condition of a vehicle;
- and
- comparing the steering system data received from the one or more vehicle sensors to an expected value of the steering system data to determine if a traction steer event has occurred.
A method for detection of a traction steer event, comprising:
- receiving first steering system data from one or more vehicle sensors;
- receiving second steering system data from one or more vehicle sensors;
- determining a relationship between the first and second steering system data;
- and
- comparing the relationship between the first and second steering system data to an expected relationship between the first and second steering system data to determine if a traction steer event has occurred.
A system for detecting and compensating for a traction steer event, comprising:
- means for receiving steering system data from one or more vehicle sensors;
- means for determining a current operating condition of a vehicle;
- and
- means for comparing the steering system data received from the one or more vehicle sensors to an expected value of the steering system data to determine if a traction steer event has occurred.
