Problems solved by technology

However, even after the high-voltage battery is disconnected, electric power (charge) remains in capacitors, etc. included in the power control unit including the inverter and the converter. Therefore, when the discharge of the remaining electric power in the capacitor is delayed, the Leakage occurs

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same reference numerals are assigned to the same or corresponding parts in the drawings, and description thereof will not be repeated.

[0028] figure 1 It is an overall block diagram of the vehicle 1 of this embodiment. Vehicle 1 includes engine 10 , first MG (Motor Generator: motor generator) 20 , second MG 30 , power distribution device 40 , speed reducer 50 , power control unit (Power Control Unit, hereinafter referred to as “PCU”) 60 , battery 70 , drive wheel 80 , and an electronic control unit (Electronic Control Unit, hereinafter referred to as “ECU”) 200 .

[0029] The engine 10 is an internal combustion engine that generates a driving force for rotating a crankshaft by combustion energy generated when a mixture of air and fuel is combusted. The first MG20 and the second MG30 are motor generators driven by AC.

Abstract

The vehicle is equipped with: engine; EHC (Electric Heating Catalyst); 1st MG (Motor Generator) that generates counter electromotive force when the vehicle collides; battery; Transformed converters and inverters; and an ECU (200). The PCU is connected to the battery via the SMR (System Main Relay). The EHC is connected between the converter and the inverter via the EHC relay. The ECU ( 200 ) determines whether a vehicle collision has occurred ( 210 ), and in the event of a vehicle collision, turns off the SMR to disconnect the battery from the PCU ( 220 ), and closes the EHC relay to connect the EHC to the PCU. The first MG is electrically connected, thereby consuming counter electromotive force generated by the first MG upon vehicle collision through the EHC ( 230 ).

Description

technical field [0001] The present invention relates to a technique of consuming electric power generated by a vehicle at the time of a vehicle collision in advance. Background technique [0002] A vehicle that runs by driving a running motor with electric power from a high-voltage battery is generally equipped with a control system that disconnects the high-voltage battery from other devices by turning off a system main relay when the vehicle collides. However, even after the high-voltage battery is disconnected, electric power (charge) remains in capacitors, etc. included in the power control unit including the inverter and the converter. Therefore, when the discharge of the remaining electric power in the capacitor is delayed, the A leakage has occurred. [0003] In view of such a problem, Japanese Unexamined Patent Application Publication No. 2010-93934 (Patent Document 1) discloses a method for consuming electric power remaining in a capacitor of an inverter by an air-...
