<p><P>PROBLEM TO BE SOLVED: To excellently perform power limit in order to prevent a power source voltage from lowering when a large power consumption type vehicle state control device such as an electric power steering device or an active stabilizer is operated. <P>SOLUTION: In this power source supply system in a vehicle, a power source controller 10 monitors the operating state of the electric power steering device 30, and in the case that a high probability of a change to a state that requires large power is estimated, the power source controller 10 increases computing speed related to the limitation of power consumption, communicating speed between the electric power steering device 30 and the communicating speed of a vehicle control device as an object to be limited in the power consumption thereof (for example, a defogger device 40) to stand by in an improved responsiveness state. By this, even if large power is suddenly consumed, the limitation of power consumption is performed without a delay, and the lowering of the power source voltage is prevented. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
