Abstract:
1. A system installed in a vehicle having an internal combustion engine, a transmission, and a clutch with a driver-operable clutch member, according to a driver's operation of the driver-operable clutch member, the clutch being engaged in a first state to allow a transfer of power from the internal combustion engine to the transmission and disengaged in a second state to shut off the transfer of the power, the transmission having one gear position selected from a plurality of gear positions for converting, according to the selected one of the plurality of gear positions, the power to be outputted from the transmission, the plurality of gear positions including a neutral position, the system being configured to restart, according to at least one engine restart condition is met, the internal combustion engine that has been automatically controlled for stop thereof, the system comprising: a restart-condition determiner configured to determine whether the one gear position of the transmission is any gear position in the plurality of gear positions other than the neutral position and an operated variable of the driver's clutch operable member is increased from a first threshold value and thereafter to become lower than the first threshold value and lower than a second threshold value, the second threshold value being higher than a preset value corresponding to a clutch-meet point, the clutch-meet point representing a start of the transfer of the power from the internal combustion engine to the transmitter; and a restart controller configured to determine that the at least one engine restart condition is met to thereby carry out the restart of the internal combustion engine when it is determined that the one gear position of the transmission is any gear position in the plurality of gear positions other than the neutral position and the operated variable of the driver's clutch operable member is increased from the first threshold value and thereafter to become lower than the first threshold value and lower than the second threshold value.
