The invention provides a vehicle control method and an ECU. The vehicle control method comprises the steps of calculating an engine target idling speed corresponding to a current elevation when detecting that a vehicle non-power part starting instruction is received; judging whether the current elevation is not higher than a first preset elevation threshold or not, wherein a vehicle may stall under an environment that the current elevation is higher than the first elevation threshold; when determining that the current elevation is not higher than the first elevation threshold, controlling a vehicle non-power part to be started; and controlling an engine to rotate according to the engine target idling speed. Through adoption of the scheme, the driving comfort can be taken into considerationwhile the vehicle is prevented from stalling in high-elevation regions.
