<P>PROBLEM TO BE SOLVED: To effectively prevent a malfunction caused by the temporary lowering of a voltage of a battery, when restarting an engine upon satisfying conditions of the restart of the engine. <P>SOLUTION: An electrical component control device of a vehicle includes: the battery 1 mounted to the vehicle; an automatic stop controller 5 which performs the automatic stop control and restart control of the engine; and an on-board electrical component 6 which is brought into an operation state by power fed from the battery 1. In the device, an input/output characteristic is set so that an output of the electrical component becomes large as an input signal to the electrical component 6 becomes large, and also there are provided a booster 7 which boosts the voltage of the battery 1 and supplies it to the electrical component 6 when restarting the engine 2 by the automatic stop controller 5, and an input/output characteristic controller which changes the input/output characteristic so as to reduce an output change rate of the electrical component 6 in a region in which the input signal to the electrical component 6 is large when the booster 7 is operated compared with a region in which the input signal is small. <P>COPYRIGHT: (C)2012,JPO&INPIT |
