摘要： A vehicle has a frame, a front suspension assembly, a pair of skis, an endless drive track, and an internal combustion engine. The engine has: a motor-generator having a rotor and a stator, the motor-generator being operable in motor mode and in generator mode; a recoil starter operable to rotate a crankshaft of the engine via the rotor in a same direction as does the motor-generator in generator mode; at least one sensor adapted for sensing at least one engine parameter; and an engine control unit (ECU) receiving a signal from the at least one sensor, the ECU controlling a rotation of the crankshaft by one of the motor-generator and the recoil starter based on the signal.

摘要： In response to a restarting request generated during a stopping period, in which fuel injection is stopped to automatically stop engine operation, either starter starting or combustion starting is selected. In the starter starting, the engine is restarted using a starter motor. In the combustion starting, the engine is restarted through fuel injection and ignition without using the starter motor. If the rotational resistance acting on the crankshaft is determined to be of such a magnitude that the combustion starting is impossible, the starter starting is carried out in response to the restarting request generated during the stopping period.

摘要： The rotation speed and the crank position of an engine in an engine stopping process are detected; then, in the case where when the detected crank position is at an intermediate point between the top death center of any one of the cylinders and the top death center of the cylinder following said one of the cylinders, it is determined that the engine rotation speed is within a predetermined range, drive of the starter is prohibited for a predetermined time period.

摘要： A system for a vehicle, includes a rockback detection module and a starter disabling module. The rockback detection module receives a crankshaft position signal from a bi-directional crankshaft sensor and selectively indicates that a crankshaft of an engine is rotating in a first direction based on the crankshaft position signal. The engine rotates in a second direction that is opposite to the first direction when the engine is running. The starter disabling module disables current to a starter motor when the crankshaft is rotating in the first direction.

摘要： Provided is an engine starting device, including: starter control means for causing, when the restart condition is established during a period in which a meshing inhibition condition for a ring gear and a pinion gear is established, the pinion gear and the ring gear to mesh with each other after the meshing inhibition condition is released, thereby restarting the engine. The starter control means determines the meshing permission condition and the meshing inhibition condition based on at least an engine rotation speed, and determines the release of the meshing inhibition condition before the engine completely stops based on at least one of the engine rotation speed and an elapsed time after the establishment of the meshing inhibition condition.
