摘要： An engine starting system that regulates a position of a pinion gear of a starter motor between an engaged position and a disengaged position includes a solenoid pinion armature (SPA) that is coupled to the pinion gear and that is movable between a first position and a second position to move the pinion gear between the disengaged position and the engaged position. A damper dampens a velocity of the SPA during movement of the SPA to the second position to inhibit noise generation.

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 control system includes an auto-stop module, an auto-start module, and a starter module. The auto-stop module stops an engine when a brake pedal position is greater than a threshold position and a transmission is in a drive gear. The auto-start module starts the engine when the brake pedal position is less than a minimum position and the engine stop is initiated. When the engine start is initiated and an engine speed is greater than zero, the starter module engages a pinion gear of a starter with a ring gear of an engine by reciprocally actuating the pinion gear N times between a retracted position and an extended position, wherein N is an integer greater than two.

摘要： An electronic control unit for regulating the air/fuel ratio of an internal combustion engine is disclosed. The electronic control unit has an open loop calibration for regulating air/fuel ratio that is corrected with a closed loop signal developed by an integral controller. The integral controller bases the closed loop correction signal on a signal from an exhaust gas composition sensor located in the engine exhaust manifold. Various conditions of the system are sensed by a closed loop sensor condition detector to provide information on whether the sensor is up to operating temperature and is operative. If the exhaust gas sensor is functioning and the operating system parameters indicate the system operation should move to closed loop control, the loop is closed by the condition detector. Included in the condition detector circuit is a timer whose cycle is RPM dependent. The timer will time out if the sensor has not indicated an operational capability in one timing cycle or a set number of RPM counts and will generate a signal indicating a sensor failure. After closing the loop, the detector circuit will check for a sensor transition on a periodic basis related to the authority of the integral controller and provide a signal to open the closed loop if the transition does not occur. A rich burst generator is provided to perturbate the loop periodically to produce a rich transition of the sensor if it is operable. A latching failure indicator circuit is additionally included in the system to energize a visual indicator and alert an operator if the failure condition occurs.
