Problems solved by technology

However, it is foreseeable that if the cable wires are thickened, the weight will increase, or the wiring bundle will be made stronger or the volume will increase, which will inevitably require a design change, or reduce the workability of the vehicle assembly.
On the other hand, if the target adjustment voltage is set uniformly high considering the voltage drop caused by the resistance of the harness, there is a possibility that the battery will be overcharged.

Abstract

The invention provides a power generation control device of an idling stop vehicle, which can constantly supply proper charging voltages without changing a current wire harness whether the charging residue of a battery is large or small. In a moment (t1), lag angular coordinate (theta x) power generation among gain control is started. In a moment (t2) when the lag angular coordinate (theta x) exceeds a switching threshold value (theta ref) and lasts for a designated voltage boost judging period (delta), voltage boost control starts in a moment (t3). The voltage boost control is performed in a way to simply gradually increase a target adjusting voltage (Vt) through an increase rate (delta V). Later in a moment (t6), decrease control on the lag angular coordinate (theta x) is started. In a moment (t8) when the lag angular coordinate (theta x) is lower than the switching threshold value (theta ref) and lasts for a voltage decrease judging period (delta), voltage decrease control is started in a moment (t10). The voltage decrease control is performed in a way to simply gradually decrease a target adjusting voltage (Vt) through a decrease rate (delta V).

Description

technical field [0001] The present invention relates to a power generation control device for an idling stop vehicle, and more particularly, to a power generation control device for an idling stop vehicle capable of solving the problem of insufficient charging caused by the reduction of the generated power due to the resistance of the wiring harness of the charging system, thereby reducing the charging voltage. Background technique [0002] As a vehicle power generator, a three-phase synchronous generator driven by an engine is known. The AC power generated by the three-phase synchronous motor is rectified by a three-phase full-wave rectifier, voltage-regulated, and charged to the battery. Patent Document 1 discloses a power generation control in which, in a system in which power generated by a generator driven by an engine is supplied to a battery and an electrical load, a drive circuit performs an advanced or retarded energization angle with respect to a stator coil.
