Embodiment Construction

[0010] The present invention relates to a starter control system, wherein the ignition switch command control module automatically triggers the starter relay according to a predetermined logic, but if the ignition switch continues to issue a start command, the activation of the starter relay can be extended beyond the time allocated by the predetermined logic. In this way, the benefits of automatic starter control can be realized without having to take all control out of the driver's hands.

[0011] figure 1 A non-limiting example of a starter control system 10 according to the invention is shown. The starter control system 10 includes a starter motor 12 , a power source 14 , a starter relay 16 , a control module 18 , and an ignition switch 20 .

[0012] The starter motor 12 initiates movement of the pistons within the internal combustion engine before combustion alone can reliably move the pistons. Starter motors may be configured for use with many different types and / or si...

Abstract

A starter control system is disclosed. In one example, the starter control system allows both automatic and manual control over an engine starting sequence. The starter control system can enhance starter control system flexibility.

Description

technical field [0001] The present invention relates to a starter control system. Background technique [0002] Before combustion alone could reliably reciprocate the piston, electric starter motors could be used to initiate piston movement within an internal combustion engine. Some starter motors are controlled by a starter motor relay that has a low side that is controlled through a powertrain control module and a high side that is energized directly through the ignition switch circuit. Once the engine starts, the PTCM deactivates the low side of the starter relay, which turns off the starter motor. [0003] The inventors herein have recognized several problems with this approach. Specifically, the cranking duration is limited by how long the driver holds the ignition switch in the start position. If the ignition switch is released prematurely, this can result in excess fuel in the cylinders, prolonged engine cranking, and / or potentially rough engine starting. [0004]...
