<p><P>PROBLEM TO BE SOLVED: To provide an error detecting device of a current sensor having first and second batteries connected in parallel so as to supply power to an electric load for a vehicle, a generator driven by an engine and supplying the power to the electric load and both of the batteries, and first and second current sensors detecting charging and discharging currents of the first and second batteries, and capable of precisely and easily detecting an error of a current sensor. <P>SOLUTION: This device has a relay for shutting off the supply of the power to an electric load when an ignition switch is turned off. A control unit determines errors of the current sensor based on detection values Ib1, Ib2 of first and second current sensors when the supply of the power to the electric load is shut off by the relay. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
