Charging control unit of electric power generation control device for motor vehicle
First Claim
1. An electric power generation control device, having electric power generation means driven by an internal combustion engine mounted on a motor vehicle, for generating electric power and determining a power generation voltage for supplying the electric power to an electrical load and electricity storage means of the vehicle, comprising:
- electricity storage amount detection means for detecting an amount of electricity stored in the electricity storage means, by integrating an input or output current to or from the electricity storage means;
voltage lowering means for lowering the power generation voltage when a predetermined electricity storage amount is detected by the electricity storage amount detection means;
time measuring means for measuring time elapsed after termination of charging and discharging of the electricity storage means; and
lowering prohibition means for prohibiting the power generation voltage, generated by the power generation means, from being lowered by the voltage lowering means if the time elapsed after termination of the charging and discharging, measured by the time measuring means, is longer than or equal to a predetermined time.
