SYSTEM AND METHOD FOR IDLE ENGINE STOP
摘要:
An automatic transmission is disclosed providing eight forward ratios and one reverse ratio wherein the first forward ratio is selected by engaging exactly one friction brake using an electro-mechanical actuator. An operating method is disclosed for a vehicle having a transmission with this characteristic. The disclosed operating method permits the engine to be shut off to save fuel while the vehicle is stationary and then to start moving before an engine driven pump creates hydraulic pressure to engage the clutches.
