Brake assisted control of an engine restart event |
摘要 |
A method for restarting an engine of a vehicle includes engaging a gear of a transmission that driveably connects the engine and wheels of the vehicle; maintaining a current brake pressure greater than a reference brake pressure; initiating an automatic engine restart; using a timer to count down during a period of predetermined length; using a pump to produce a desired magnitude of brake pressure sufficient to suppress a wheel torque surge produced by restarting the engine and to hold the vehicle stationary; and releasing the brake pressure if either the timer expires or a peak in engine speed occurs.
