Circuitry for starting relay

Starter

The present invention provides as tarter capable of keeping a state where a pinion and a ring gear maintain meshing with each other when an engine stops without providing a plunger stopper using a solenoid or the like.

The helical spline engagement part is a part where a helical spline on the outer periphery of an output shaft of a starter motor and a helical spline on the inner periphery of the torque transmission member mesh with each. Consequently, the above state continues without a plunger stopper using a solenoid or the like.

Vehicle engine starting apparatus

A vehicle engine starting apparatus capable of automatically restarting an engine by quickly responding to a subsequent engine restart request can be realized even if engagement of a pinion gear with a ring gear is failed in the process of a stop of the engine.

Method and apparatus to evaluate a starter for an internal combustion engine

An internal combustion engine including a starter is shown. A method for monitoring the starter includes determining electrical energy consumed by pinion and motor solenoids operative to activate and rotate a pinion gear of an electrically-powered motor meshingly engageable to a starter ring gear portion of a flywheel of the engine during an engine starting event. Current ringing in the pinion and motor solenoids is monitored during the engine starting even, and a fault is identified in the pinion and motor solenoids based upon the current ringing and the electrical energy consumption of the starter during the engine starting event.

System for cranking internal combustion engine by engagement of pinion with ring gear

In a system, an engine restating module is capable of executing an engine restart task to crank an automatically stopped engine if an engine restart condition is met. The engine restart task includes energization of a mechanism to thereby shift a pinion to be engaged with a ring gear, and energization of a motor to rotate the pinion. A deenergizing module is capable of deenergizing the motor if an interrupting request that interrupts restart of the automatically stopped engine is generated during execution of the engine restart task. A maintaining module is capable of maintaining energization of the mechanism to engage the pinion with the ring gear even if the interrupting request that interrupts restart of the automatically stopped engine is generated during execution of the engine restart task.

Method and device for operating a starter of a vehicle

In a method for operating a starter of a vehicle, a position of a starter pinion is detected, and an advance of the starter pinion is regulated as a function of the detected position. For example, the advance during the meshing of the starter pinion with a starter ring gear of a drive motor of the vehicle is regulated.
