A vehicle having an integrated function of assisting an engine and compressing a refrigerant includes a motor unit and a compression unit coupled within a housing, and a first clutch unit coupled to a rotation shaft of the motor unit or a rotation shaft of the compression unit and that connects or releases a driving force of an engine and a driving force of the motor unit.

A hybrid vehicle includes a control unit. The control unit limits an output of an electrically powered compressor included in an air conditioner when a shutter has a closed failure in which the shutter cannot be set to an opened state.

An electric work vehicle includes a mounted body enabling execution of a specific work. The electric work vehicle further includes a main frame, a cab in a front portion of the main frame, an electrical component unit on the main frame in a position lower than a lower surface of the cab, and a power take off (PTO) unit having a work machine drive unit for driving a work machine to execute the specific work by the mounted body, and a mounted motor for supplying rotational power, by electric power of the battery, to the work machine drive unit. In the PTO unit, the mounted motor is in a position lower than the lower surface of the cab and in a lowermost layer region of a space where the electrical component unit is disposed, and the work machine drive unit is disposed in a position rearward from the mounted motor.

A hybrid vehicle and an air-conditioning system thereof. A heating part of the air-conditioning system may be provided with an electric heating device (120, 220) and a water heating device (130, 230), the electric heating device (120, 220) is turned on and the water heating device (130, 230) is turned off when the temperature of engine cooling water is lower than a preset temperature threshold, and the electric heating device (120, 220) is turned off and the water heating device (130, 230) is turned on when the temperature is higher than the preset temperature threshold. A refrigerating part of the air-conditioning system may comprise a mechanical compressor and selected auxiliary power units (20) as a portion of a plurality of auxiliary power units, and when cold air flow needs to be supplied, an air-conditioning controller (110, 210) sends an enabling instruction to a power controller (61) to control the selected auxiliary power units (20) to enter a forced working mode. The air-conditioning system of the present invention can rapidly supply heat while reducing electricity consumption of a whole vehicle, and can also achieve good refrigerating effects in low cost and reduce energy consumption. The air-conditioning system according to the present invention is especially suitable for a series hybrid vehicle with a plurality of auxiliary power units.

A solar-thermal powered recreational vehicle featuring a solar-thermal air conditioning system integrated with a solar clean energy system to provide a recreational vehicle having improved energy efficiency. In an embodiment employing the principles of the present invention, the solar-thermal powered recreational vehicle can comprise a clean energy system for providing electrical power to the recreational vehicle, whereby the clean energy system features one or more solar photovoltaic panels, a batter bank, and a generator operatively coupled to a hybrid inverter. The solar-thermal air conditioning system is powered by the clean energy system, with the solar-thermal air conditioning system featuring a solar-thermal collector panel functioning to superheat compressed refrigerant prior to the compressed refrigerant being transmitted to the condenser. Because the compressor is the most energy-intensive component in the traditional direct expansion AC system, the use of free solar energy by the present invention to reduce the work load on the compressor significantly reduces the overall energy requirements of the recreational vehicle, thereby providing a recreational vehicle capable of operating on solar and battery power alone for significant periods of time.

A rear occupant alert device according to an embodiment comprises a first object detection unit; a second object detection unit; and a control unit configured to control operations of the first and second object detection units, wherein the first object detection unit includes a passive infrared sensor (PIR) sensor, wherein the second object detection unit includes a radar module, and the control unit is configured to control a movement of an object inside a vehicle through the first object detection unit, and to control a movement of an object through the second object detection unit when the movement of the object is not detected through the first object detection unit.

A thermal management system for a vehicle includes a high-temperature side pump that draws and discharges a heat medium, a compressor that draws and discharges a refrigerant in a refrigeration cycle, a high-pressure side heat exchanger that exchanges heat between a high-pressure side refrigerant in the refrigeration cycle and the heat medium circulated by the high-temperature side pump, a heat medium-outside air heat exchanger that exchanges heat between the heat medium circulated by the high-temperature side pump and outside air, and a pump control unit that controls an operation of the high-temperature side pump such that the operation of the high-temperature side pump is continued even after the compressor is stopped. Thus, the cycle efficiency exhibited when restarting the compressor can be improved.
