<P>PROBLEM TO BE SOLVED: To improve fuel consumption while preventing occupants of a vehicle from having incongruity ontraveling state. <P>SOLUTION: When the vehicle speed of an internal combustion engine does not reach a predetermined vehicle speed #V0 and varies with lowering tendency after restart, a value, which is obtained by adding longer one of a predetermined time B in which counting of an idle stop prohibiting timer is performed after the restart and a vehicle speed zero reaching time D in which the vehicle speed reaches zero to a predetermined time C which is the elapsed time from when the vehicle speed reaches zero, is set as re-idle stop permission delay time α, and execution of another idle stop is permitted after the elapse of the re-idle stop permission delay time α. Longer one of a predetermined time A in which counting of a fuel injection start delay timer is performed after the restart and the idle stop permission delay time α is set as fuel injection start delay time β, and timing for starting fuel injection to the internal combustion engine is delayed for the period of the fuel injection start delay time β. <P>COPYRIGHT: (C)2007,JPO&INPIT |
