Abstract:
A camera for taking a state behind a vehicle is installed in a position laterally shifted from the rear center of the vehicle. An image processing unit generates a rear image from a camera image by shifting merely a rectangular area of the camera image so that a vertical center line thereof can substantially accord with the center line along the lengthwise direction of the vehicle. Furthermore, processing for correcting lens distortion may be performed. As a result, when the vehicle is moved straight backward, an object present on the center line of the vehicle moves vertically in substantially the center of the screen, so that a user can be prevented from having an odd feeling to see the image.

Abstract:
Provided is a radar device carried on a mobile unit for detecting an obstacle around the mobile unit. The radar device includes a transmission unit (201), a receiving unit (202), a speed acquisition unit (204), a reference signal acquisition unit (205) and a signal processing unit (203). The transmission unit (201) transmits a radar beam modulated from a transmission signal with a predetermined frequency. The receiving unit (202) receives a reception signal, which is demodulated with a predetermined frequency from a radar beam transmitted from the transmission unit (201) and reflected by the obstacle. The speed acquisition unit (204) acquires the speed of the mobile unit. The reference signal acquisition unit (205) acquires the reception signal as a reference signal, in case the speed acquired by the speed acquisition unit (204) is at a predetermined value or higher. The signal processing unit (203) detects the obstacle by using the reception signal and the reference signal.

PROBLEM TO BE SOLVED: To perform guidance of alignment between a power receiving part and a power feeding part with a simple structure, and also to reduce a burden on a driver in performing alignment between the power receiving part and the power feeding part.SOLUTION: A sensor 104 is provided around a power feeding part 140. A feeding side control part 103 starts the entire or a part of an area of the sensor 104, and detects that the started area has been trampled by the wheel of a vehicle 150. A power feeding side communication part 101 acquires steering angle information of the wheel, and notifies the result of such detection that the started area has been trampled by the wheel. The power feeding side control part 103 starts the area corresponding to a steering angle indicated by the steering angle information acquired by the power feeding side communication part 101.

PROBLEM TO BE SOLVED: To provide a safe drive assisting device capable of accurately informing a user of the distance from a user's own vehicle to an object. SOLUTION: The drive assisting device is provided with a main control part 2. The main control part 2 is connected to at least one object detection sensor 1 mounted to the vehicle 50, detecting the object at a periphery of the vehicle and obtaining position information between the object and the object detection sensor 1 including a distance L and a direction θ to the object at the periphery of the vehicle. The main control part 2 calculates a correction distance La, i.e., a distance of the object and the vehicle 50 using the position information obtained by the object detection sensor 1, and displays the calculated correction distance La on a display 3.

Abstract:
PROBLEM TO BE SOLVED: To provide an on-board charger capable of reducing the size thereof by charging the on-vehicle battery by using a three-phase bridge circuit of a drive inverter.SOLUTION: An onboard charger 100 is mounted on a vehicle which runs in a manner that, after converting a DC power stored in an on-vehicle battery 170 into an AC power with a three-phase bridge circuit 108 on a drive inverter 150, the converted AC power is supplied to a drive motor 180. A primary coil 104 receives AC power supply from an external power source 160. A secondary coil 105 is electrically connected to the three-phase bridge circuit 108 and is electromagnetically coupled with the primary coil 104 to transform the voltage of the AC power supplied the primary coil 104 to thereby charge the on-vehicle battery 170 via the three-phase bridge circuit 108.
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply control device, power supply control method, and power interchange system that slow the deterioration speed of a storage battery and lengthen the life of the storage battery.SOLUTION: A power supply control device comprises: a power switching unit which switches the flow of power among a regular power supply for supplying power, a storage battery capable of charging and discharging, and a load; and a control unit which performs switch control of the power switching unit. The control unit adopts a configuration to shift the storage battery to a dormant state in which the storage battery is not charged or discharged until a set dormant time period passes (S34, S36, S37) when the storage battery is switched from a charging state to a discharging state or when the storage battery is switched from the discharging state to the charging state, and to control the power switch unit such that power supply can be done from the regular power supply to the load at the time of dormant state (S45).

PROBLEM TO BE SOLVED: To achieve both the reduction of a mental burden accompanying driving and the prevention of the reduction of charging efficiency, by guiding the alignment of a charger with a power supply device in consideration of the remaining amount of power of a storage battery.SOLUTION: A vehicle display device 100 is mounted on a vehicle using the storage battery 103 that is charged from the power supply device on the ground in a non-contact manner as a power source. The charger 102 charges the storage battery 103 by approaching the power supply device. A camera 108 photographs an image in a moving direction of the vehicle. A display unit 111 also displays a guide line for guiding a power receiving unit 101 to a position at which the power receiving unit approaches the power supply device, when displaying the image photographed by the camera 108. A control unit 105 makes the line width of the guide line to be displayed on the display unit 111 narrower as the remaining amount of power of the storage battery 103 is smaller.
