Abstract
A method of densensitizing includes determining a relative roll angle, determining when the vehicle is in a transitional maneuver, and when the vehicle is in a transitional maneuver, setting a roll signal for control to the relative roll angle, reducing control effort and controlling a safety system (38) correspondingly.
Claims18
A method of controlling a vehicle comprising:
- determining a relative roll angle;
- determining when the vehicle is in a transitional maneuver;
- and
- when the vehicle is in a transitional maneuver, setting a roll signal for control to the relative roll angle.
1 more element
A method of controlling a vehicle comprising:
- determining a relative roll angle;
- determining a wheel lift status;
- and
- when the relative roll angle is above a non-transition threshold and the wheel lift status is grounded, adjusting the reference bank angle to the maximum of either the reference bank angle or the relative roll angle plus the wheel departure angle.
1 more element
A method of operating a vehicle comprising:
- determining roll condition;
- holding a peak brake pressure to counteract rollover;
- determining a first wheel departure angle;
- determining a second wheel departure angle after the first wheel departure angle;
- and
- when the change of the first wheel departure angle and the second wheel departure angle is less than a threshold, releasing the peak brake pressure.
3 more elements
A method of operating a vehicle comprising:
- determining a drive torque;
- determining a wheel departure angle;
- and
- when the drive torque is below a first threshold and the wheel departure angle is less than a second threshold, initiating active wheel lift detection.
