A drive apparatus for a vehicle, which supplies more electric power to a motor which supplements the drive power of an engine and collects energy from an exhaust to be able to improve fuel consumption and reduce the total amount of the exhaust, is realized by comprising an engine coupled to a drive
A drive apparatus for a vehicle, which supplies more electric power to a motor which supplements the drive power of an engine and collects energy from an exhaust to be able to improve fuel consumption and reduce the total amount of the exhaust, is realized by comprising an engine coupled to a drive wheel to generate drive power for the vehicle, a generator motor coupled to an output shaft of the engine and the drive wheel, a battery, a power control unit, and a power generation unit which generates electric power using an exhaust of the engine, and selects a charge mode when the vehicle is braked and when an engine output is equal to or greater than an output needed to drive the vehicle, wherein the electric power generated by the generator is stored in the battery, and energy is collected from the exhaust using the power generation unit.

1. A drive apparatus for a vehicle, comprising: an engine to be coupled to a drive wheel of the vehicle to generate drive power for the vehicle;a generator motor to be coupled to an output shaft of the engine and the drive wheel;a battery;a power control unit which selects one of: (i) a charge mode
1. A drive apparatus for a vehicle, comprising: an engine to be coupled to a drive wheel of the vehicle to generate drive power for the vehicle;a generator motor to be coupled to an output shaft of the engine and the drive wheel;a battery;a power control unit which selects one of: (i) a charge mode in which the generator motor is operated as a generator to charge the battery with electric power generated by the generator motor, and (ii) an assist mode in which electric power is supplied to the generator motor from the battery, and the generator motor is operated as an electric motor to supplement an output of the engine; anda power generation unit which is electrically connected to the battery and the power control unit, and which has a fuel cell which is disposed in an exhaust gas passage of the engine to generate electric power using only combusted exhaust gas of the engine as fuel;wherein the power generation unit comprises a heat generating device which comprises a junction portion where one end portion of a P type thermoelectric transducing member and one end portion of an N type thermoelectric transducing member are connected, and generates electric power with a Seebeck effect;wherein the junction portion is associated with the fuel cell in the exhaust gas passage; andwherein another end portion of the P type thermoelectric transducing member and another end portion of the N type thermoelectric transducing member are located outside the exhaust gas passage. 2. The drive apparatus for a vehicle according to claim 1, wherein: the power control unit selects the charge mode when the vehicle is braked and when the engine generates an output equal to or greater than an output needed to drive the vehicle, andthe power control unit selects the assist mode when the output of the engine is less than the output needed to drive the vehicle. 3. The drive apparatus for a vehicle according to claim 1, wherein the fuel cell comprises a single cell type solid oxide fuel cell. 4. The drive apparatus for a vehicle according to claim 1, wherein: the vehicle comprises a four-wheel drive vehicle, andone of a couple of front drive wheels or a couple of rear drive wheels are driven by the engine, and the other couple of drive wheels are driven by the generator motor. 5. The drive apparatus for a vehicle according to claim 2, wherein: the vehicle comprises a four-wheel drive vehicle, andone of a couple of front drive wheels or a couple of rear drive wheels are driven by the engine, and the other couple of drive wheels are driven by the generator motor. 6. The drive apparatus for a vehicle according to claim 1, wherein: the vehicle comprises a three-wheeled vehicle having a steered wheel which sets a moving direction of the vehicle, and a couple of drive wheels, andone of the couple of drive wheels is driven by the engine, and the other one of the drive wheels is driven by the generator motor. 7. The drive apparatus for a vehicle according to claim 2, wherein: the vehicle comprises a three-wheeled vehicle having a steered wheel which sets a moving direction of the vehicle, and a couple of drive wheels, andone of the couple of drive wheels is driven by the engine, and the other one of the drive wheels is driven by the generator motor. 8. The drive apparatus for a vehicle according to claim 1, wherein the vehicle comprises a two-wheeler having a steered wheel which sets a moving direction of the vehicle, and a drive wheel. 9. The drive apparatus according to claim 2, wherein the vehicle comprises a two-wheeler having a steered wheel which sets a moving direction of the vehicle, and a drive wheel.
