Abstract
A power generation controlling device for vehicle includes a communication controlling circuit, a power generation voltage and excitation current controlling circuit, and a communication frame processing circuit. The communication controlling circuit communicates with an ECU using a communication frame. The power generation voltage and excitation current controlling circuit controls power generation based on power generation control information in the received communication frame. The communication frame processing circuit decodes contents of power generation control information (i.e., signal switching data) included in the communication frame based on a signal switching bit in the same communication frame. Two types of contents or more that are switched based on the signal switching bit are assigned to the power generation control information in the communication frame. The power generation voltage and excitation current controlling circuit controls power generation based on the power generation control information of which the contents are specified by the switching information.
