Abstract
When a predetermined stop condition is satisfied, an engine is stopped. When a predetermined start condition is satisfied, a motor in a starter is driven and the engine is started. When a voltage of a battery for supplying electric power to the motor becomes lower than a threshold value while the motor is driven, stoppage of the engine is thereafter restricted. The threshold value increases as an engine rotation speed at the time when the motor is driven increases.

A control device for an engine which is stopped when a predetermined stop condition is satisfied and cranked by a motor when a predetermined start condition is satisfied after it is stopped, comprising:
- a control unit that restricts stop of said engine after a voltage of a battery supplying electric power to said motor becomes lower than a threshold value while said motor is driven and said engine is cranked, wherein
- said threshold value increases as a rotation speed of said engine at a time when said motor is driven increases.
A control device for an engine which is stopped when a predetermined stop condition is satisfied and cranked by a motor when a predetermined start condition is satisfied after it is stopped, comprising:
- a control unit that restricts stop of said engine in accordance with a voltage of a battery supplying electric power to said motor while said motor is driven and said engine is cranked, wherein
- the voltage of said battery at a time when stop of said engine is restricted increases as a rotation speed of said engine at a time when said motor is driven increases.
