ENGINE START / STOPPING CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an engine start/stop control system capable of surely preventing engine stop during vehicle travel. SOLUTION: Driver circuit parts 26, 27 are provided in an electricity passage between an electric power source control part 15 and IG1 relay 22 and IG2 relay 23. FET 29 operates based on operation signal from the electric power source control part 15 or output signal from a latch circuit part 41 to operate the relays 22, 23. The latch circuit part 41 keeps an operation state of the FET 29 to keep operation states of the relays 22, 23 unless a start/stop switch is pressed under vehicle non-travel condition once the relays 22, 23 operate.
