A product purchase system includes a first communication terminal carried by an advertising user, a second communication terminal provided to be movable with a vehicle, and a server. The first communication terminal sends advertisement product information indicating a product worn or held by the advertising user to the server. The second communication terminal sends a product search request including second position information and second time information to the server. The second position information indicates a position of the vehicle when a specific action performed by an occupant in the vehicle is detected while the vehicle is moving. The second time information indicates a clock time when the specific action is detected. The server extracts candidate product information from the advertisement product information, based on the second position information and the second time information. The server then sends the extracted candidate product information to the second communication terminal.

Product purchase system, server, first communication terminal and second communication terminal

The invention includes first and second motors, first and second differential mechanisms, and first to eighth decoupling mechanisms. The first and second motors transmit power to left and right wheels. First differential mechanisms distribute the power from the first and second motors. The first and second mechanisms are interposed between the first differential mechanism and the left front wheel and between the differential mechanism and the left rear wheel. The third and fourth decoupling mechanisms are interposed between the first motor and the first decoupling mechanism and between the first motor and the second decoupling mechanism. The fifth and sixth decoupling mechanisms are interposed between the second differential mechanism and the right front wheel and the right rear wheel, respectively. The seventh and eighth decoupling mechanisms are interposed between the second motor and the fifth decoupling mechanism and between the second motor and the sixth decoupling mechanism.

Drive apparatus for electric-motor four-wheel drive vehicle

A drive apparatus for an electric-motor four-wheel drive vehicle includes first and second motors, first and second differential mechanisms, and a propeller shaft. The vehicle includes a first wheel pair including first left and right wheels and a second wheel pair including second left and right wheels and positioned on opposite side to the first wheel pair in a front-rear direction. The first and second motors are configured to output first output torque and second output torque, respectively. The first differential mechanism is configured to distribute the first output torque to a first torque-transmitting member coupled to the first left wheel and a third torque-transmitting member coupled to the propeller shaft. The second differential mechanism is configured to distribute the second output torque to the third torque-transmitting member and a second torque-transmitting member coupled to the first right wheel.

Drive apparatus for four-wheel drive vehicle

A driving device of an electric-motor four-wheel drive vehicle includes a propeller shaft, a first differential mechanism, a second differential mechanism, a first decoupling mechanism, a second decoupling mechanism, a first motor, and a second motor. The propeller shaft transmits power between front wheels and rear wheels. The first differential mechanism is disposed in a drive shaft of the front wheels. The second differential mechanism is disposed in a drive shaft of the rear wheels. The first decoupling mechanism decouples the first differential mechanism from the propeller shaft. The second decoupling mechanism decouples the second differential mechanism from the propeller shaft. The first motor is coupled to the propeller shaft via a part closer to the front wheels than the first decoupling mechanism or a part closer to the rear wheels than the second decoupling mechanism. The second motor is coupled between the first and second decoupling mechanisms.

Driving device of electric-motor four-wheel drive vehicle

A drive device includes a first clutch mechanism that couples or decouples power transmission systems for front and rear wheels, a first electric motor disposed on a front or rear wheel side and coupled to the first clutch mechanism, a second electric motor disposed on the other of the front and rear wheel sides and coupled to the first clutch mechanism, a second clutch mechanism that couples or decouples the first electric motor and front drive shafts, a planetary gear mechanism that distributes output of the first electric motor to the first and second clutch mechanisms, and a third clutch mechanism that limits a difference between a first rotational element that transmits the output of the first electric motor to the first clutch mechanism and a second rotational element that transmits the output of the first electric motor to the second clutch mechanism.
