Title:
HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2017127126
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hybrid vehicle for performing non-arc opening of a switch when performing operation stop processing during inverter-less travel due to a communication abnormality between control units.SOLUTION: When a communication abnormality occurs between an HV-ECU 310 and an MG-ECU 320, inverter-less travel is executed for traveling using braking-torque generated in a motor generator 10 rotated by an engine with inverters 221, 222 turned into the gate shutdown state. The MG-ECU 320 stands by for opening of a system main relay SMR 160 until the current of a main battery 150 becomes zero after generating an engine stop command when receiving an operation stop command from a driver during the inverter-less travel. The MG-ECU 320 stops a DCDC converter 620 when detecting stop of motor generators 10, 20 and engine on the basis of the rotation frequency of the motor generators 10, 20 during the inverter-less travel.SELECTED DRAWING: Figure 2
