  • Patent number: 10536028
    Abstract: In an example, a method for signaling a generator includes coupling a transmitter to a generator, a receiver to a transfer switch, a first conductor between a first output of the transmitter and a second input of the receiver, and a second conductor between a second output of the receiver and a first input of the transmitter. The method also includes providing an input power signal to the transmitter, and transmitting an electrical-loop signal around a closed loop circuit. After transmitting the electrical-loop signal, the method includes determining a resistance of the closed loop circuit. If the determined resistance is zero or infinite, then the method includes activating an alarm system. If the determined resistance is at a first reference-resistance value, then the method includes maintaining a deactivation of the generator. If the determined resistance is at a second reference-resistance value, then the method includes activating the generator.

  • Patent number: 9382891
    Abstract: An engine control apparatus includes an engine control unit that is configured to control a ring gear, a starting device and a pinion gear. The engine control unit is further configured to perform a control to engage the ring gear and pinion gear with each other in an idling stop state, and to control a pinion gear driver. The pinion gear driver actuates the pinion gear to disengage from the ring gear. In particular, the pinion gear driver actuates the pinion gear to disengage from the ring gear while the ring gear is not rotated and while a starter motor of the starting device is rotated or while injectors of an engine are caused to inject fuel into cylinders of the engine to ignite an air-fuel mixture therein, so as to release engagement of the pinion and ring gears.

  • 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: 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.
