Problems solved by technology

When the driver's restart request occurs during the engine reverse rotation period, if the starter pinion gear is connected to the reverse rotation ring gear immediately in response to the restart request, the gear may be worn or an excessive load may be applied to the starter.

Embodiment Construction

[0031] Below, use Figure 1 to Figure 14 The configuration and operation of an engine starting device according to an embodiment of the present invention will be described.

[0032] First, use figure 1 The structure of the engine starting device of this embodiment is demonstrated.

[0033] figure 1 It is a configuration diagram of an engine starting device according to an embodiment of the present invention. exist figure 1 An example of the overall system configuration and circuit connection of an engine starting device according to an embodiment of the present invention is schematically shown in .

[0034] The starter 101 is roughly composed of a magnetic switch 102 , a pinion 103 , and a motor body 105 . The electric motor 105 is a so-called DC motor, and generates rotational force by applying a DC voltage. When necessary, the magnetic switch 102 pulls the lever 102A in the arrow A1 direction to move the pinion 103 on the motor rotation shaft in the arrow A2 direction,...

Abstract

An engine starter and starting method with which a starter drive prohibited interval can be reduced and the restart time can be brought earlier to the maximum possible limit, while the wear on the starter and the load thereupon are kept down within an allowable range, are provided. A starter (101) includes a magnetic switch (102), a pinion gear (103), and a motor body (105). A control device (109) prohibits, in a reverse rotation region directly before an engine stops completely when being stopped automatically, starting of shifting of the pinion gear during an interval of equal to or less than a predetermined negative rotation that is taken as a starter drive prohibited interval; and starts, in a region other than the starter drive prohibited interval, shifting of the pinion gear immediately in response to an engine restart request, thus connecting the pinion gear with the ring gear and starting the engine, and controls restarting of the engine on the basis of the engine rotational speed detected by an engine rotation sensor (110).

Description

technical field [0001] The invention relates to an engine starting device and a starting method for starting an engine, in particular to an engine starting device and a starting method suitable for use in an automobile adopting an idle stop system. Background technique [0002] Some automobiles in recent years are equipped with an idling stop system that temporarily stops the engine automatically when a predetermined condition is met during operation for the purpose of energy saving and environmental protection. The idling stop system automatically stops the engine when the driver stops the vehicle, for example, waiting for a signal, and then automatically restarts the engine when the engine needs to be turned on by the driver's operation or the like. The following method is mostly used when restarting the engine: using a so-called pinion gear push starter motor, pushing the pinion gear during starting so that the pinion gear meshes with a ring gear directly connected to the...
