System and Method for Preventing Clutch Burst
| Content Provider | The Lens |
|---|---|
| Abstract | A control system for a vehicle having a manual transmission system includes an anti-lock braking system configured to apply brakes of the vehicle, a clutch pedal configured to control engagement/disengagement of a clutch disc with a pressure plate of the manual transmission system, and a controller configured to perform a clutch burst prevention technique when the clutch pedal is depressed such that the clutch disc is disengaged from the pressure plate, the clutch burst prevention technique comprising: obtaining a set of operating parameters of the vehicle, determining a vehicle speed threshold based on the set of operating parameters, the vehicle speed threshold being a speed of the vehicle at which clutch burst begins to occur, and when the vehicle speed is within a first threshold amount from the vehicle speed threshold, decreasing the vehicle speed by commanding the anti-lock braking system to apply the vehicle brakes. |

| Claim | A control system for a vehicle having a manual transmission system, the control system comprising: an anti-lock braking system configured to apply brakes of the vehicle; a clutch pedal configured to control engagement/disengagement of a clutch disc with a pressure plate of the manual transmission system; and a controller configured to perform a clutch burst prevention technique when the clutch pedal is depressed such that the clutch disc is disengaged from the pressure plate, the clutch burst prevention technique including: obtaining a set of operating parameters of the vehicle, determining a vehicle speed threshold based on the set of operating parameters, the vehicle speed threshold being a speed of the vehicle at which clutch burst begins to occur, and when the vehicle speed is within a first threshold amount from the vehicle speed threshold, decreasing the vehicle speed by commanding the anti-lock braking system to apply the vehicle brakes. The control system of claim 1 , wherein the controller is configured to command the anti-lock braking system to apply the vehicle brakes until the vehicle speed decreases to another vehicle speed threshold equal to a difference between the vehicle speed threshold and a second threshold amount. The control system of claim 1 , wherein the set of operating parameters comprises a gear ratio of a transfer case connected between the manual transmission system and front and rear axles of the vehicle. The control system of claim 3 , wherein the controller is configured to perform the clutch burst prevention technique in response to the gear ratio of the transfer case being transitioned to a low range gear ratio. The control system of claim 4 , wherein the vehicle speed threshold is approximately 15 miles per hour. The control system of claim 3 , wherein the set of operating parameters further comprises a selected gear ratio of the manual transmission system. The control system of claim 6 , wherein the set of operating parameters further comprises a ratio between the front and rear vehicle axles and a size of wheels of the vehicle. A method of controlling a vehicle powertrain having a manual transmission system, the method comprising: controlling a clutch disc based on a position of a clutch pedal of the vehicle, wherein the clutch pedal controls engagement/disengagement of the clutch disc with a pressure plate of the manual transmission system; and performing, by a controller of the vehicle, a clutch burst prevention technique when the clutch pedal is depressed such that the clutch disc is disengaged from the pressure plate, the clutch burst prevention technique including: obtaining, by the controller, a set of operating parameters of the vehicle, determining, by the controller, a vehicle speed threshold based on the set of operating parameters, the vehicle speed threshold being a speed of the vehicle at which clutch burst begins to occur, and when the vehicle speed is within a first threshold amount from the vehicle speed threshold, decreasing, by the controller, the vehicle speed by commanding an anti-lock braking system of the vehicle to apply brakes of the vehicle. The method of claim 8 , wherein the commanding of the anti-lock braking system to apply the vehicle brakes is performed until the vehicle speed decreases to another vehicle speed threshold equal to a difference between the vehicle speed threshold and a second threshold amount. The method of claim 8 , wherein the set of operating parameters comprises a gear ratio of a transfer case connected between the manual transmission system and front and rear axles of the vehicle. The method of claim 10 , wherein the clutch burst prevention technique is performed in response to the gear ratio of the transfer case being transitioned to a low range gear ratio. The method of claim 11 , wherein the vehicle speed threshold is approximately 15 miles per hour. The method of claim 10 , wherein the set of operating parameters further comprises a selected gear ratio of the manual transmission system. The method of claim 13 , wherein the set of operating parameters further comprises a ratio between the front and rear vehicle axles and a size of wheels of the vehicle. |
