| 摘要 | A method for controlling restart of an engine in a hybrid electric powertrain, includes engaging a gear of a transmission, releasing a brake pedal, maintaining fluid pressure at an adaptively determined magnitude in a wheel brake, initiating a restart the engine, and reducing fluid pressure in the wheel brake when the engine restarts. | ||

| 主权项 | 1. A method for controlling an engine restart in a hybrid electric powertrain, comprising: (a) engaging a gear of a transmission driveably connected to the engine; (b) maintaining fluid pressure in a wheel brake after a brake pedal is released; (c) initiating the engine restart and starting a timer; (d) reducing fluid pressure in the wheel brake if the timer expires or a peak in engine speed following said restart is detected; wherein step (d) further comprises: monitoring engine speed to determine that a peak in engine speed has occurred; and reducing fluid pressure in the wheel brake after the peak in engine speed occurs. | ||
