Abstract: A power control unit is provided with a converter; a filter capacitor that is connected onto one side of converter; a smoothing capacitor that is connected onto the other side of converter; an MG-ECU that is operated to control converter with power supplied from filter capacitor; and a casing that houses these constituent elements therein. In order to electrically discharge filter capacitor and smoothing capacitor, an MG-ECU controls converter in such a manner as to alternately repeat ON/OFF of an npn-type transistor for a lower arm of an IPM and ON/OFF of an npn-type transistor for an upper arm of IPM, and further, to set a time of ON of npn-type transistor for the upper arm longer than that of ON of npn-type transistor for the lower arm.

Abstract: A power control unit (PCU) case accommodates an electric circuit of a PCU, which includes a first capacitor and is operated by electricity supply from a storage battery. In the electric circuit, a first bus bar is connected to a part in the vicinity of the anode of the first capacitor, and a second bus bar is connected to a part in the vicinity of the cathode of the first capacitor. A discharge mechanism is formed by connecting in series a switch activated by an explosive actuator and a discharging resistor. The discharge mechanism is integrally fixed to the PCU case. When a collision of the vehicle is detected, the discharge mechanism short-circuits the first bus bar and the second bus bar with each other through the activation of the switch. Accordingly, the discharge mechanism is connected in parallel with the first capacitor, so that the discharging resistor discharges the first capacitor.

Abstract: A vehicle uses electric power from a mounted power storage device to drive a motor generator by a PCU to generate traction driving force. The vehicle can execute, as a function to discharge residual electric charge from a capacitor in PCU, MG discharging in which current is applied to the motor generator while preventing generation of torque for discharging, and PCU discharging through the conduction loss of switching elements in the PCU for discharging. In an event of detecting collision of the vehicle, an HV-ECU executes PCU discharging by priority, and executes MG discharging when the voltage of the capacitor is high.

Abstract: A vehicle converts DC power from a power storage device into AC power by an inverter to run by driving a three-phase motor generator. A switching unit is provided at a path electrically connecting the motor generator and the inverter. The switching unit includes a relay corresponding to each phase. Each relay is configured to connect a coil of a corresponding phase in the motor generator to a corresponding driving arm in the inverter, or to a connection node of capacitors connected in series between direct current side terminals of the inverter. When short-circuit failure is detected at a switching element of any one of the phases in the inverter, an ECU switches the relay of the corresponding phase in the switching unit to the side of the connection node.

Abstract: An ECU activates a shutdown permission signal and provides it to an AND gate when a shutdown signal is inactive. Thus, when an abnormality sensing device does not sense an abnormality, the ECU always keeps the shutdown permission signal active. The AND gate performs logical AND between a signal provided from the abnormality sensing device and the shutdown permission signal to provide the shutdown signal to inverters. When a limp-home run permission signal becomes active while the shutdown signal is active, the ECU inactivates the shutdown permission signal.
