Abstract:
1. An automotive internal combustion engine control system comprising: a transmission mechanism that transmits output of a starting motor to an internal combustion engine to start the internal combustion engine, transmits output of the internal combustion engine to an auxiliary machinery while the internal combustion engine is in operation, and transmits output of the starting motor to the auxiliary machinery while the internal combustion engine is stopped for a predetermined condition, wherein: the starting motor is operable as a generator, a controller controls the transmission mechanism to transmit rotation of a drive shaft included in the starting motor to a crankshaft included in the internal combustion engine at a high first gear ratio in starting the internal combustion engine, and to transmit rotation of the crankshaft of the internal combustion engine to the drive shaft of the starting motor at a low second gear ratio while the internal combustion engine is in operation, and the starting motor serves as a generator when the rotation of the crankshaft of the internal combustion engine is transmitted to the drive shaft of the starting motor at the second gear ratio, wherein the transmission mechanism includes a brake that is put on by a signal given thereto by the controller to transmit the rotation of the drive shaft of the starting motor to the crankshaft of the internal combustion engine at the high first gear ratio in starting the internal combustion engine, and is put off when traveling speed of an associated vehicle increases beyond a predetermined traveling speed after the internal combustion engine has been started.
