    摘要: The present invention relates to a start-stop “mild hybrid” vehicle with a starting system which utilizes traditional engine and transmission architecture. The present invention separates the pinion actuator solenoid from the starter motor power switching circuit. A power relay is provided to switch the starter motor. The pinion gear in the present invention is pre-shuttled to, and held in mesh with, the flywheel ring gear during engine stop conditions. A “prime current” is then applied to the power relay just below that which is required to energize the power relay. Upon request for an engine start, the current will increase to energize the relay and allow the starter motor to spin. A significant amount of time lag is thusly removed from the starting system permitting an expedient restart and launch. The pinion actuator solenoid in this invention may also have two coils which may be selectively energized.

    摘要: A method for variable operation of a vehicle transmission using rough road sensing includes defining a first set of parameters to calibrate the vehicle transmission for a smooth road condition and a second set of parameters to calibrate the vehicle transmission for a rough road condition. The method includes sensing a road condition, generating a road condition signal corresponding to the road condition, and measuring a magnitude of the road condition signal. The method includes switching from the first set of parameters to the second set of parameters to operate the vehicle transmission when the magnitude of the road condition signal exceeds a first predetermined threshold. The method includes switching from the second set of parameters to the first set of parameters to operate the vehicle transmission when the magnitude of the road condition signal is less than a second predetermined threshold that is different than the first predetermined threshold.
