Claim:
1. An automatic stopping device for an internal combustion engine of a vehicle comprising a battery that is charged by an operation of the internal combustion engine and an electrical load that is operated by power stored in the battery, comprising a programmable controller programmed to: stop, during a vehicle stoppage, the internal combustion engine automatically when a first automatic stopping condition is established; and stop, during vehicle travel, the internal combustion engine automatically when a second automatic stopping condition is established; wherein the first automatic stopping condition is established when a battery voltage or a battery state of charge of the battery equals or exceeds a first threshold, and the second automatic stopping condition is established when the battery voltage or the battery state of charge of the battery equals or exceeds a second threshold that is set to be greater than the first threshold, and wherein the controller is further programmed to prevent automatic stoppage of the internal combustion engine, during vehicle travel, when the battery voltage or the battery state of charge of the battery is lower than the second threshold.
