PROBLEM TO BE SOLVED: To provide means that inhibits combustion energy from being wasted in a case where deceleration-time fuel cut is prohibited.SOLUTION: A traveling control unit of a vehicle includes fuel cut execution means 54 that executes cut of fuel feed to an engine when a vehicle meets a predetermined deceleration condition, fuel cut prohibition means 56 that prohibits fuel feed cut when the temperature of an exhaust system catalyst exceeds a predetermined value, and deceleration means 38 that decelerates the vehicle. The traveling control unit 10 of a vehicle further includes fault presence determination means 34 that determines presence or absence of a traveling fault of the vehicle on the basis of sense information concerning a situation occurring ahead of a vehicle in a traveling direction. Even when execution of fuel feed cut is prohibited by the fuel cut prohibition means 56, if the fault presence determination means 34 determines absence of the traveling fault of the vehicle 1, the deceleration means 38 is not allowed to perform deceleration.SELECTED DRAWING: Figure 2 |
