<p>PURPOSE: A power control technique is provided to realize the power supply according to the status of a vehicle when a starting device of the vehicle is turned off. CONSTITUTION: In turning off a first and a second ignition switches(S110), A first CPU(Central Processing Unit) checks an error of an electronic control brake system(S120). In checking the errors through the first CPU or a second CPU(Y of S120), the first and the second CPUs turn off a first and a second main relays respectively(S300). In turning off a passenger detection switch(Y of S400) when the first and the second CPUs decides the electronic control brake system is normal(N of S120), the first and the second main relays are turned on for a certain time as a self maintaining process at a normality. The continuous time to turn on the first and the second main relays is changed according to a voltage of a battery for a vehicle.</p> |
