    摘要: An engine control system comprises a camshaft, a cam phaser module, a pressure sensor, and an engine control module. The camshaft is operably coupled to a crankshaft of an engine. Rotation of the camshaft operates a fuel pump in driving communication with a cam of the camshaft. The cam phaser module provides hydraulic pressure to change a rotational position of the cam about the camshaft. The pressure sensor determines a cam phaser pressure signal based on a pressure of fluid in the cam phaser module. The engine control module diagnoses a condition of the fuel pump based on the cam phaser pressure signal.

    摘要: A method of valve lift failure detection may include determining first and second intake air pressures in an engine having intake valve lifters that selectively operate intake valves in first and second lift modes. The first intake air pressure may correspond to an intake stroke of a first piston of the engine when the engine is commanded to operate in the first lift mode and the second intake air pressure may correspond to an intake stroke of a second piston of the engine when the engine is commanded to operate in the first lift mode. The method may further include determining a difference between the first and second intake air pressures and diagnosing an intake valve lifter failure when the difference exceeds a predetermined limit.

    摘要: An electronic enhanced mobility control interface of a mobility enhancement system implemented in a motor vehicle having a conventional electronic throttle control system. The electronic enhanced mobility throttle interface includes an auxiliary electronic throttle sensor in duplication of the conventional throttle pedal electronic throttle sensor, wherein the driver's selection of either the auxiliary or throttle pedal position throttle sensor is interfaced transparently to an engine electronic controller, as for example an engine control module (ECM/PCM) for processing to the electronic throttle control (ETC) subsystem. The electronic mobility enhancement throttle interface further includes an auxiliary throttle control by which the driver executes throttle commands to the auxiliary electronic throttle sensor, a data switch for connecting one or the other of the throttle pedal position and auxiliary electronic throttle sensors processing electronics to the ECM/PCM.
