摘要： A motor vehicle includes at least one camera capturing images of an environment outside of the motor vehicle. A proximity sensor detects an object disposed adjacent to the motor vehicle. An electronic processor receives the images captured by the at least one camera, and receives a proximity signal from the proximity sensor. The proximity signal is indicative of whether an object is disposed adjacent to the motor vehicle. The electronic processor determines, based upon the images captured by the at least one camera and the proximity signal, whether the motor vehicle is disposed within an enclosure. The electronic processor receives an engine start request signal that has been wirelessly transmitted by a user. In response to receiving the engine start request signal, the electronic processor causes the engine start system to start an engine of the motor vehicle when the motor vehicle is not disposed within an enclosure.

摘要： An engine assembly is provided that includes an engine having a crankshaft that is caused to rotate response to a firing of the engine, a backplate affixed to the engine and comprising one or more air flow passages formed therethrough, and an engine cooling fan operatively coupled to the crankshaft so as to be rotated by the crankshaft, the engine cooling fan coupled to the crankshaft on a side of the backplate opposite the engine. The engine assembly also includes a fan cover mounted over the engine cooling fan and secured to the backplate, the fan cover including an opening through which an air flow is provided to the engine cooling. The backplate and the fan cover collectively form an air guide that directs a flow of cooling air generated by the engine cooling fan through the one or more air flow passages of the backplate and to the engine.

摘要： The invention relates to a method for rotational positioning of a heat engine rotor (3) that is in a stopped position (θA) to a target position (θ0), comprising the following steps: a device for detecting the angular position of the rotor (3) determines an angular difference (Δθ) from the target position (θ0), a speed set-point (Ωc(θ)) as a function of the angular position (θ) of the rotor (3) is established from the angular difference (Δθ), with a rising slope less than a predetermined value (a) followed until a high speed value is reached less than a predetermined value (Ω0), and a falling slope less than a predetermined value (b), the rotor (3) is set in motion following the speed set-point (Ωc(θ)).

摘要： An engine automatic stop/restart device includes a ring gear which is linked to a crank shaft of the engine, a starter motor which is energized so as to be rotated, a pinion gear which transmits a rotation of the starter motor to the ring gear, and a pinion gear movement unit which is energized so as to move the pinion gear in a direction of the ring gear, whereby the pinion gear is engaged to the ring gear, in a state where the engine automatic stop/restart device automatically stops the engine when an engine automatic stop condition is established, and restarts the engine when an engine restart condition is established, and includes an inertially-rotating-restart-decision unit which permits or prohibits a restart of the engine, which is inertially rotating after the engine is automatically stopped, in accordance with a detection result of an oil temperature of the engine.

摘要： A method for controlling a starter-generator during a startup phase of a motor intended to be driven in rotation in a predetermined nominal direction by the starter-generator, the starter-generator comprises a stator comprising at least one polyphase stator winding and a rotor comprising at least one rotor winding coupled magnetically to the stator winding. The method comprises a step of starting up the motor, during which the polyphase stator winding and the rotor winding are supplied with electric power to start up the motor, the startup step preceded, when the motor is initially rotating in the direction opposite to the nominal direction, by a braking step, during which a current is drawn from at least one polyphase stator winding and the rotor winding is supplied with electric power.

摘要： A circuit configuration is described, for starting an internal combustion engine, using at least one starter, which includes a starter motor, an engaging relay, a switching relay and a control relay, the control relay being able to be controlled by an ignition switch, the engaging relay being able to be controlled by the control relay and a current path of the starter motor being able to be switched using the switching relay. In order for the starter, for starting an internal combustion engine, to operate more accurately, and thus to achieve a longer service life, the switching relay is able to be controlled as a function of the occurrence of a specified event, at least in the switching-off process. This has the advantage that the switching relay is able to interrupt a current path from the starter motor earlier in time, especially a main current path, so that energizing in the reverse direction is avoided. Consequently, the switching relay is able to release the current path of the starter motor specified in such a way that in the switching-off process, during the disengaging of a starter pinion, pinion bounce is clearly reduced, or even eliminated. In the switching-off process of the starter, a motion of the starter pinion back in the direction towards the ring gear, after the disengagement, is avoided.

摘要： A method for starting an internal combustion engine has the steps of: oscillating a crankshaft of the engine using the electrical actuator; then injecting fuel in a combustion chamber and igniting the fuel in this combustion chamber to cause the crankshaft to turn in a reverse direction; then injecting fuel in another combustion chamber and igniting the fuel in the other combustion chamber to cause the crankshaft to turn in a forward direction; and then injecting fuel in the other combustion chamber and igniting fuel in the other combustion chamber to cause the crankshaft to turn in the forward direction.
