Problems solved by technology

[0004] In the state where the generator and the capacitor are simply connected, there may be a problem that when starting an internal combustion engine such as an engine by driving an external drive device such as a kick starter of a two-wheeled vehicle, the When the voltage is low, all the power generated by the generator due to driving the external drive device is used to charge the capacitor, and the internal combustion engine cannot be started until the capacitor is fully charged.
However, in this case, there may be a large charging current rushing to the capacitor when connecting the generator to the capacitor
In addition, if a large charging current flows rapidly to the capacitor in this way, the voltage of the control unit such as the ECU will drop, and the internal combustion engine may stop.

Abstract

A control circuit for internal combustion engine (100) controls an internal combustion engine (60). The control circuit for internal combustion engine (100) comprises: a voltage detection circuit (20) for detecting the voltage of a capacitor (C) which charges itself with the power generated by a generator (41) that generates power using a driving force generated by the internal combustion engine (60) and a driving force generated by driving an external drive device (65), and supplies a cell motor (46) with the power stored therein; and a control unit (50) for charging only the capacitor (C) by controlling the power supplied from the generator (41) to the capacitor (C) on the basis of the voltage of the capacitor (C) detected by the voltage detection circuit (20). The internal combustion engine (100) further comprises a constant current circuit (10) that connects to the generator (41) and the capacitor (C) to generate a constant current from the current generated by the generator (41), and thus charges only the capacitor (C) with the constant current.

Description

technical field [0001] The invention relates to an internal combustion engine control circuit and an internal combustion engine control method for controlling the internal combustion engine. Background technique [0002] Conventionally, it is known that a capacitor (capacitor) is used in addition to a battery (for example, refer to Japanese Patent Laid-Open No. 2010-083178, Japanese Patent Laid-Open No. 2011-047380 No., Japanese Patent Laid-Open No. 2010-259147 and Japanese Patent Laid-Open No. 2009-180125). It is also known that an internal combustion engine such as an engine is started by driving an external drive device such as a kick starter of a two-wheeled vehicle when the starter motor cannot be started due to low battery voltage. [0003] In addition, as a system using a storage battery, there are image 3 system described in . Such as image 3 As shown, the internal combustion engine control circuit 200 connected to the battery B includes: a load control circuit 1...
