Abstract
A method for operating a speed control system of a vehicle is provided. The method comprises detecting an occurrence of a slip event, of a step encounter event, or of both events at a leading wheel of the vehicle. The method also comprises predicting that the occurrence of the detected event(s) will occur at a following wheel of the vehicle. The method yet further comprises automatically controlling vehicle speed, vehicle acceleration, or both vehicle speed and acceleration in response to the detection, the prediction, or both the detection and prediction. A speed control system comprising an electronic control unit (ECU) configured to perform the above-described methodology is also provided.
Claims17
A method of operating a speed control system of a vehicle having an electronic control unit (ECU), comprising:
- detecting by the ECU an occurrence of at least one of a slip event and a step encounter event at a leading wheel of the vehicle;
- predicting by the ECU that an occurrence of said at least one of a slip event and a step encounter event will occur at a following wheel of the vehicle, wherein the prediction is based upon a combination of two or more of a speed of the vehicle, an angle of the leading wheel, an angle of a steering wheel of the vehicle, or a wheelbase distance between the leading wheel and the following wheel;
- and
- automatically controlling by the ECU at least one of vehicle speed and vehicle acceleration in response to said predicting.
A speed control system for a vehicle, comprising:
- an electronic control unit (ECU), the ECU configured to:
- detect an occurrence of at least one of a slip event and a step encounter event at a leading wheel of the vehicle;
- predict that an occurrence of said at least one of a slip event and a step encounter event will occur at a following wheel of the vehicle, wherein the ECU is configured to make the prediction based upon a combination of two or more of a speed of the vehicle, an angle of the leading wheel, an angle of a steering wheel of the vehicle, or a wheelbase distance between the leading wheel and the following wheel;
- and
- output a signal to automatically control at least one of vehicle speed and vehicle acceleration in response to said predicting.
A vehicle comprising a speed control system, the speed control system comprising:
- an electronic control unit (ECU), the ECU configured to:
- detect an occurrence of at least one of a slip event and a step encounter event at a leading wheel of the vehicle;
- predict that an occurrence of said at least one of a slip event and a step encounter event will occur at a following wheel of the vehicle, wherein the ECU is configured to make the prediction based upon a combination of two or more of a speed of the vehicle, an angle of the leading wheel, an angle of a steering wheel of the vehicle, or a wheelbase distance between the leading wheel and the following wheel;
- and
- output a signal to automatically control at least one of vehicle speed and vehicle acceleration in response to said predicting.
