ELECTRIC POWER GENERATION CONTROL DEVICE FOR MOTOR VEHICLE
First Claim
1. An electric power generation control device 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/output current to/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/discharqing of the electricity storage means; and
lowering prohibition means for prohibiting the power generation voltage from being lowered by the voltage lowering means if the time elapsed after termination of the charging/discharging, measured by the time measuring means, is longer than or equal to a predetermined time.
