Power control device for vehicle
First Claim
1. A vehicle power control device for controlling driving power and electric generation power of a motor generator mounted in a vehicle by using a power converter containing a power element and a power element driving signal generating means for generating a signal to drive the power element, comprising:
- a monitoring control device for monitoring the status of the power converter and outputting an abnormality-occurrence electric generation switching signal when abnormality occurs under the control of the electric generation power of the motor generator,wherein a first electric generation control function is executed corresponding to the output of the power element driving signal generating means under a state where there is no output of the abnormality-occurrence electric generation switching signal, and the output of the power element driving signal generating means is stopped when there is an output of the abnormality-occurrence electric generation switching signal, thereby executing a second electric generation control function based on a diode rectifying mode of the power element.

Abstract
In a power control device for a vehicle, a monitoring control device 2 disposed separately from a power converter 1 judges normality/abnormality of the power converter 1, and sets an abnormality-occurrence electric generation switching signal 4 to ON/OFF, whereby a first electric generation control function corresponding to an output of power element driving signal generating means is forcedly stopped, and also a second electric generation control function based on a diode rectifying mode of a power element is started.
