摘要:
A method for driving a hybrid vehicle with a propulsion system including a combustion engine, an electric machine with a rotor and a stator and a planetary gear with three components including a sun gear, a ring gear and a planet wheel carrier, where an output shaft of the combustion engine is connected to a first component, an input shaft of a gearbox is connected to a second component and the rotor of the electric machine is connected to a third component. The vehicle is driven forward by the electric machine. The reverse gear engaged in the gearbox drives the third component of the planetary gear to rotate with a negative rotational speed while a brake brakes the first component. Thereafter, move the component brake to an open position, so that the output shaft of the combustion engine rotates with a positive rotational speed so that the combustion engine may be started.

A method for driving a hybrid vehicle in connection with start of a combustion engine (2) in a propulsion system (1) of the vehicle, which propulsion system comprises a planetary gear with three components in the form of a sun gear (10), a ring gear (11) and a planet wheel carrier (12). The output shaft (2a) of a combustion engine (2) is connected to a first of said components, an input shaft (3a) of a gearbox (3) being connected to a second of said components and the rotor (9b) of an electric machine (9) is connected to a third of said components. The method starts when the vehicle is being driven forward by the electric machine, which with a reverse gear engaged in the gearbox drives the third component of the planetary gear to rotate with a negative rotational speed while a component brake (28) brakes said first component. The method comprises the step to transfer the component brake to an open position, so that the output shaft of the combustion engine planetary gear is brought to rotate with a positive rotational speed, whereby the combustion engine may be started.

At a time of stopping an internal combustion engine, inertia energy of the engine is kept constant, for example, by controlling a number of engine revolution constant, while controlling combustion of the engine. By utilizing the controlled inertia energy, the engine is stopped at a predetermined crank angle position. Since the engine is stopped at the predetermined crank angle position by utilizing the controlled inertia energy, a large amount of energy for controlling the stop position of the energy is not needed, and the energy needed for the stop control can be reduced. Since the inertia energy utilized for the stop control is always controlled in a predetermined state, the engine can be stopped at a proper position reliably each time.

The present invention includes a target-engine-speed acquisition means for acquiring a target engine speed necessary to reduce engine speed, thereby stopping the engine at a target stop position; a crank-angle acquisition means for acquiring a crank angle indicative of the position of a crankshaft; and a target-engine-speed correction means for correcting the target engine speed according to the acquired crank angle. Since the target engine speed is corrected according to the crank angle, the engine can be stopped at the target stop position even if the friction in the engine, the electric motor, etc. varies, even if the temperature or viscosity of the lubricating and cooling oils varies, or even if the vehicle is accelerated or decelerated during the reduction of the engine speed.

L'invention propose un démarreur de véhicule automobile, du type comportant un contacteur (10) muni d'un contact mobile (44) susceptible d'être déplacé en translation entre une position de repos dans laquelle le contact (44) est en appui contre un élément conducteur fixe (16) et vers laquelle il est sollicité par des moyens de rappel élastique (54), et une position active, dans laquelle le contact mobile établit le raccordement électrique entre une borne d'entrée (28) du courant, et une borne d'alimentation (30) du moteur du démarreur, du type dans lequel il est prévu des moyens qui, lorsque le contact mobile (44) est en position de repos, permettent d'établir un contact électrique entre la borne d'alimentation (30) et la masse électrique du véhicule, le contact mobile (44) et la borne d'alimentation (30) étant reliés électriquement par des moyens de rappel élastique (54) en matériau conducteur.
摘要:
In a hybrid vehicle including an internal combustion engine (1), an electric motor (4), a generator (3), a battery (9), and a catalytic converter (11) disposed in an exhaust system of the engine, a determination is made as to whether a condition for stopping the engine is established, based on an operating state of the vehicle. Then, the fuel supply to the engine is cut off when the condition for stopping the engine is established, and a load (for example, a load of the generator) is applied to the engine so as to restrict rotation of the engine.
