  • Patent number: 7180201
    Abstract: A starting apparatus for an engine has a plurality of cylinders and an output shaft. The apparatus includes a power supply, an inverter having a switching element, a motor generator, an ECU, A crank angle sensor. The motor generator is coupled to the output shaft and connected to the power supply through the inverter. The ECU energizes the motor generator by controlling the inverter when the engine is started. The ECU causes ignition to occur in a specific cylinder that contains air-fuel mixture and is in an expansion stroke in an engine stopping state. The crank angle sensor indirectly detects a rotational speed of the motor generator. After the ignition caused, the ECU prohibits the motor generator from being energized until the rotational speed detected reaches or exceeds a predetermined value. As a result, the apparatus curbs an excessive increase in the temperature of a switching element.

  • Patent number: 6369532
    Abstract: A control system for an electric motor having an integral flywheel rotor. The motor includes a stator mounted co-axially with the engine crankshaft and a rotor surrounding the stator. A sensor is positioned near the rotor for sensing its rotational speed. The sensor is coupled to a controller. The controller is operable to deliver an output signal to the stator to start the internal combustion engine. While the engine is starting, the processor steps the starter motor from a low speed to a high speed. Once the engine has started and is rotating at a speed greater than a trigger speed, the processor delivers another output signal such that the motor is commutated at a speed that is less than the speed of the rotor to generate a speed slip. By commutating the motor in this manner, it acts as a generator. The speed slip is regulated when the motor is generating electric power so that the motor produces a constant output voltage.

  • Patent number: 5820172
    Abstract: An operating strategy for a hybrid electric vehicle (HEV) manages the flow of energy to both supply the motive demand power of the HEV and maintain the charge of the energy storage system (ESS). A controller operates the main power unit (HPU) and ESS and, using an optimal fuel cost strategy, scans all possible combinations of power from the HPU and ESS that satisfy the motive demand power. The combination with the lowest fuel cost is selected and the ESS is charged, when possible, using marginal charging; but, if the state of charge of the ESS falls below a certain level, fast charging is invoked. A minimum power threshold strategy can be used rather than the fuel cost strategy. The minimum power threshold strategy determines the optimal compromise of HPU operation and ESS operation to maximize fuel economy by using a motive power threshold below which the HPU is not operated except to recharge the ESS.

  • Patent number: 5818115
    Abstract: A starter dynamo having a pinion engageable with a ring gear and an armature for rotating the pinion is supplied at engine starting with an electric storage power from an electric double layered capacitor used exclusively for the starter dynamo. With this storage power, the armature rotates and, with this armature rotation, the pinion rotates. An engine ring gear is driven through the pinion to start the engine. After the engine starting, the ring gear rotation is transmitted to the armature through the pinion and the starter dynamo charges the electric double-layered capacitor. Thus, an electric storage power required for the next engine starting is charged in a short period of time.

  • Patent number: 4626696
    Abstract: A propulsion system for use in automotive vehicles wherein the flywheel is connectable with the crankshaft of the internal combustion engine by a first clutch and with the input shaft of the change-speed transmission by a second clutch. When the engine would be idling (such as during stoppage of the vehicle at an intersection) or running unnecessarily for another reason (such as during coasting of the vehicle), the two clutches are disengaged and the flywheel rotates by inertia to restart the engine, when necessary, in response to engagement of the first clutch. If the RPM of the flywheel reaches a preselected lower threshold value, a starter-generator unit automatically accelerates the flywheel so that its RPM rises above the threshold value and is thus sufficient to ensure that the engine is restarted on engagement of the first clutch.
