the idle reduction control unit 30 is implemented in the hybrid ecu 18 as illustrated in fig4 in step s 10 the idle reduction control unit 30 determines whether the vehicle is under the idle reduction at present and when the vehicle is under the idle reduction the process proceeds to step s 11 on the other hand in step s 10 when the vehicle is not under the idle reduction the process repeats step s 10 note that u2018 the vehicle is under the idle reduction u2019 denotes that the hybrid vehicle 1 is under the stoppage by the processing illustrated in the flowchart of fig3 in step s 11 the idle reduction control unit 30 determines whether a current shift position is in the d range when the current shift position is in the d range the process proceeds to step s 12 and when the current shift position is not in the d range the process proceeds to step s 13 in step s 12 the idle reduction control unit 30 determines whether the brake is operated and when the brake is not operated the process proceeds to step s 15 on the other hand in step s 12 when the brake is operated the process returns to step s 10 in step s 13 the idle reduction control unit 30 determines whether a current shift position is in a neutral range hereinafter referred to as an n neutral range and when the current shift.
