METHOD AND APPARATUS FOR MONITORING UNINTENDED VEHICLE MOTION |
| 摘要 |
A powertrain system is configured to transfer propulsion torque to a driveline of a vehicle. A method for controlling the powertrain system includes determining a magnitude of unintended vehicle motion based upon a difference between a change in actual vehicle acceleration and a change in an operator-intended vehicle acceleration. Propulsion torque to the driveline is limited when a fault associated with unintended vehicle motion is detected and the magnitude of unintended vehicle motion is less than a predetermined first threshold. |
