Starter for engines and its starting circuit

Control method and control unit for internal combustion engine starter

A method for controlling a starter device is described, having a starter motor, a meshing device and a starter pinion for meshing into a ring gear of an internal combustion engine in a motor vehicle, the meshing device for meshing the starter pinion being activated by the controller, in particular for a starting/stopping operating strategy. In order to improve vehicle comfort, in that the internal combustion engine may be restarted significantly more quickly, at least one meshing value of the meshing device for meshing the starter pinion is detected by a detecting device, stored in the controller as a reference value, and evaluated.

Control unit for an internal combustion engine starter

Ein Verbrennungsmotoranlassersteuergerät für ein Fahrzeug, das mit einem Leerlaufstoppsteuergerät (41) ausgerüstet ist, weist eine Benutzerstartschaltung (T1, T1p, T1m), eine Automatikstartschaltung (T2, T2p, T2m), einen Schaltkreis (41, T3) und eine Fehlererfassungsschaltung (41) auf. Die Benutzerstartschaltung versorgt einen Anlasser (15, 83) mit Energie, wenn ein Fahrer einen Verbrennungsmotor (13) startet. Die Automatikstartschaltung versorgt den Anlasser mit Energie, wenn das Leerlaufstoppsteuergerät den Verbrennungsmotor automatisch neu startet. Der Schaltkreis schaltet eine Energieversorgungsschaltung zur Energieversorgung des Anlassers von der Benutzerstartschaltung zur Automatikstartschaltung, nachdem die Benutzerstartschaltung begonnen hat, den Anlasser mit Energie zu versorgen, indem er bewirkt, dass die Automatikstartschaltung den Anlasser mit Energie versorgt, und indem er die Benutzerstartschaltung in einen erzwungenen Zustand versetzt, in dem die Benutzerstartschaltung gezwungen wird, die Energieversorgung des Anlassers zu stoppen. Die Fehlererfassungsschaltung bestimmt, ob die Automatikstartschaltung den Anlasser mit Energie versorgt, wenn die Energieversorgungsschaltung zur Automatikstartschaltung geschaltet wird. An internal combustion engine starter control apparatus for a vehicle equipped with an idling stop controller (41) has a user start circuit (T1, T1p, T1m), an automatic start circuit (T2, T2p, T2m), a circuit (41, T3), and an error detection circuit (41). on. The user start circuit powers a starter (15, 83) when a driver starts an engine (13). The automatic start circuit provides power to the starter when the idling stop control automatically restarts the engine. The circuit switches a power supply circuit for energizing the starter from the user start circuit to the automatic start circuit after the user start circuit has started to energize the starter by causing the automatic start circuit to energize the starter and setting the user ...

Circuit enabling start function without relay

An engine starter interlock circuit includes an interface circuit configured to present a predefined load to a transmission controller for diagnostics and receives first and second transmission start enable signals. A first logic circuit is configured to output a control signal when the first and second transmission start enable signals indicate that the transmission is in a state where starting of the engine is permitted. A second logic circuit generates a start command signals when both the control signal and one or more vehicle start enable signals indicate that starting of the engine is permitted. A latch is configured to maintain the control signal in an asserted state while the start command signal is being generated (i.e., in the asserted state). The interlock circuit includes a switch responsive to the start command signal configured to energize an electric engine starter assembly for cranking the engine.

Controller for engine starter

An engine starter controller for a vehicle equipped with an idle-stop controller includes a user-start circuit, an auto-start circuit, a switch, and a failure detector. The user-start circuit energizes a starter when a driver starts an engine. The auto-start circuit energizes the starter when the idle-stop controller automatically restarts the engine. The switch circuit switches an energization circuit for energizing the starter from the user-start circuit to the auto-start circuit after the user-start circuit starts to energize the starter by causing the auto-start circuit to energize the starter and by putting the user-start circuit into a forced state where the user-start circuit is forced to stop energizing the starter. The failure detector determines whether the auto-start circuit energizes the starter when the energization circuit is switched to the auto-start circuit.

Starting system for a combustion engine and method for operating said starting system

The invention relates to a starting system for a combustion engine and a method for operating said starting system. The starting system consists of a starter pinion which can be engaged with a motor shaft of the combustion engine via a ring gear of the motor, an electronically switchable electromotor which transmits torque to the starter pinion during starting of the combustion engine and an electronically switchable actuator whose operation can at least engage the pinion in the ring gear of the motor (pinion-engaging phase) or can decouple said components (free-wheel phase). The starting system also consists of a sensory mechanism by means of which progression of the start-up is detected and a control unit which controls the electromotor and the actuator during starting on the basis of the signals provided by the sensory mechanism.
