Claims

[Scope of Claim for Utility Model Registration] An engine rotational speed sensor, a reduction degree detection means for determining the degree of reduction in the engine rotational speed based on a change in the engine rotational speed detected by the sensor, and an engine rotational speed detected by the reduction degree detection means. a determining means for determining whether the degree of decrease in the engine rotation speed is greater than a reference value; and when the determination means determines that the degree of decrease in the engine rotation speed is greater than the reference value. 1. A control device for an on-vehicle generator, comprising: generator control means for stopping power generation of the on-vehicle generator.
