- the hybrid vehicle described in the present embodiment may be an electric vehicle having a cruising distance extending function.
- ECU 170 Electronic Control Unit 170
- Engine 100, first motor generator 110, second motor generator 120, and battery 150 are controlled by an ECU (Electronic Control Unit) 170.
- ECU 170 may be divided into a plurality of ECUs.
- This vehicle travels by driving force from at least one of engine 100 and second motor generator 120. That is, either one or both of engine 100 and second motor generator 120 is automatically selected as a drive source according to the operating state.
- the hybrid vehicle travels using only the second motor generator 120 as a drive source. . In this case, engine 100 is stopped.
- engine 100 is driven.
- the hybrid vehicle runs using only engine 100 or both engine 100 and second motor generator 120 as drive sources.
- the engine 100 is started to charge the battery 150 until the remaining capacity increases to a predetermined value.
- the engine 100 may be used only for power generation without being used as a driving source for traveling. That is, the hybrid vehicle may be a series hybrid vehicle.
- Engine 100 is an internal combustion engine. As the fuel / air mixture burns in the combustion chamber, the crankshaft as the output shaft rotates. The exhaust gas discharged from the engine 100 is purified by the catalyst 102 and then discharged outside the vehicle. The catalyst 102 exhibits a purification action when the temperature is increased to a predetermined activation temperature.
- the catalyst 102 is, for example, a three-way catalyst.
- the air / fuel ratio of the engine 100 is detected by an air / fuel ratio sensor 104.
- An O 2 sensor (not shown) may be used instead of or in addition to the air-fuel ratio sensor 104.
- the engine 100 is further provided with heaters 106 and 108.
- the heater 106 heats the cooling water of the engine 100.
- the heater 108 heats the catalyst 102.

- Engine 100, first motor generator 110, and second motor generator 120 are connected via power split mechanism 130.
- the power generated by the engine 100 is divided into two paths by the power split mechanism 130.
- One is a path for driving the front wheels 160 via the speed reducer 140.
- the other is a path for driving the first motor generator 110 to generate power.
- the first motor generator 110 is a three-phase AC rotating electric machine including a U-phase coil, a V-phase coil, and a W-phase coil.
- First motor generator 110 generates power using the power of engine 100 divided by power split mechanism 130.

For example, during normal traveling, the electric power generated by first motor generator 110 becomes electric power for driving second motor generator 120 as it is.
- the SOC of battery 150 is lower than a predetermined value, the electric power generated by first motor generator 110 is converted from AC to DC by an inverter described later. Thereafter, the voltage is adjusted by a converter described later and stored in the battery 150.
- the first motor generator 110 When the first motor generator 110 is acting as a generator, the first motor generator 110 generates a negative torque.
- the negative torque means a torque that becomes a load on engine 100.
- first motor generator 110 When first motor generator 110 is supplied with electric power and acts as a motor, first motor generator 110 generates positive torque.
- the positive torque means a torque that does not become a load on the engine 100, that is, a torque that assists the rotation of the engine 100. The same applies to the second motor generator 120.
- the second motor generator 120 is a three-phase AC rotating electric machine including a U-phase coil, a V-phase coil, and a W-phase coil. Second motor generator 120 is driven by at least one of the electric power stored in battery 150 and the electric power generated by first motor generator 110.

- the second motor generator 120 assists the engine 100 or causes the vehicle to travel by the driving force from the second motor generator 120.
- the rear wheels may be driven instead of or in addition to the front wheels 160.
- the second motor generator 120 is driven by the front wheels 160 via the speed reducer 140, and the second motor generator 120 operates as a generator. Accordingly, second motor generator 120 operates as a regenerative brake that converts braking energy into electric power.
