HYBRID AUTOMOBILE
Document Type and Number:
Japanese Patent JP2018094995
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To extend a distance which can be traveled for evacuation.SOLUTION: When an abnormality occurs in a first conversion section of a first control device, a second control device converts a first signal from a first current sensor into a first phase current by using a second conversion section and transmits it to the first control device. By comparison between a first voltage command of each phase based on the first phase current from the second control device and a first carrier wave voltage, the first control device generates a first PWM signal to control a first inverter. In addition, the first control device fixes the cycle of the first carrier wave voltage at a prescribed cycle and allows the first voltage command of each phase to be kept at a value of 0 until a reference start timing is set by the second control device. When the first voltage command of each phase has a value of 0, and the absolute value of the first phase current obtained by the second conversion section is larger than a threshold value, the second control device sets a timing shifted from the timing by 1/4 of the prescribed cycle as the reference start timing and converts the first signal into the first phase current by using the second conversion section at a cycle of 1/2 of the prescribed cycle from the reference start timing.SELECTED DRAWING: Figure 2
