<p><P>PROBLEM TO BE SOLVED: To provide a charge controlling ECU capable of performing power generation control with high accuracy even if communication via a LIN (Local Interconnect Network) communication line is in an abnormal state. <P>SOLUTION: The charge control ECU comprises a data holding unit 23 for storing information on the state of a battery, and a sensor value acquisition unit 25 for acquiring the battery voltage via a communication passage (a power supply line 70) different from a LIN communication line 50. In an abnormal state in which information cannot be acquired normally via the LIN communication line 50, a power generation amount determination unit 16 performs the power generation control of an alternator based on the information on the state of the battery stored in the data holding unit 23 and the battery voltage acquired by the sensor value acquisition unit 25. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
