1. A control apparatus for a vehicle installing thereon an engine, comprising:
- at least an electric component installed in the vehicle;
a detector configured to detect a condition of the vehicle; and
a control unit which receives input of a signal from the detector, and outputs a drive signal to the electric component, wherein said control unit determines whether or not conditions require the output of a drive signal to said electric component, and selects, based on result of said determination, either one of a low-power consumption mode that cannot output said drive signal, and a usual-power consumption mode that can output said drive signal to thereby allow said control unit per se to operate on the basis of the selected mode.

Abstract
In an engine of a vehicle provided with a normally-closed solenoid valve in a fresh air induction port of a canister, in the case where a refueling cap is open when the engine is stopped, a control module operates in a usual-power consumption mode, and forces closing of the solenoid valve. In the case where the refueling cap is closed, the control mode shifts to a low-power consumption mode, and maintains the solenoid valve in the closed condition.

16. A method of switching a mode of a control unit which controls an output of a drive signal to an electric component installed in a vehicle, comprising the steps of:
-
determining whether or not conditions require the output of a drive signal to said electric component, and based on said determination result, selecting either one of a low-power consumption mode that cannot output said drive signal, and a usual-power consumption mode that can output said drive signal. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
