  • Patent number: 9621102
    Abstract: A duty ratio calculation section (5a) of this device calculates target duty ratios of respective phases on the basis of a motor current value. When the target duty ratio of an arbitrary phase (U-phase) has become an uncontrolled duty ratio (for example, 5% or lower or 95% or higher), a duty ratio correction section (5b) obtains corrected duty ratios by either adding or subtracting a differential duty ratio, that is, the difference between the target duty ratio of the arbitrary phase (U-phase) and a controllable duty ratio (for example, 0% or 100%), to or from the target duty ratios of the other phases (V-phase, W-phase). A PWM output section (5c) applies a PWM signal, which is based on the controllable duty ratio and the corrected duty ratios, to the power device (3).

  • Patent number: 9379593
    Abstract: A vehicle drive device that has a stator and a rotor disposed on the inside of the vehicle wheel and drives the wheel, wherein the whole stator can be intensively cooled without causing an increase in production costs. The vehicle drive device comprises: the stator that has a stator core (20) and a hollow stator coil (30), is arranged on the inside of the rotating vehicle wheel (10), and electrically generates magnetic force; the rotor that has permanent magnets (11) connected to the wheel (10), and applies rotational force to the wheel (10) using the magnetic force of the stator; a cooling medium that flows through the hollow section of the stator coil (20); and a first radiator unit (50) that releases heat from the cooling medium.

  • Publication number: 20150083445
    Abstract: The present invention reliably extinguishes fires in devices that have exceeded the guaranteed temperature without the use of a sensor. An in-vehicle fire extinguisher (100) extinguishes fires using an air conditioner for heating or cooling the interior of a vehicle compartment. A coolant discharged from a compressor (101) is pumped into the compressor (101) through a circulation path (106) via a condenser (102), an expansion valve (103) and an evaporator (105). A fire extinguishing unit (104) is provided to the circulation path (106) between the expansion valve (103) and the compressor (101). When a device mounted in a vehicle exceeds the guaranteed temperature, the fire extinguishing unit (104) melts so that coolant pumped from the circulation path (106) is discharged to the exterior and extinguishes the device fire.

  • Patent number: 8341409
    Abstract: A content server apparatus (10) includes: a unique information holding unit (103) which holds unique information of an on-vehicle player apparatus (20), a content obtaining unit (101) which obtains a content from outside, an encrypting unit (104) which encrypts the obtained content, prior to a transmission request from the on-vehicle player apparatus (20), onto an encrypted content using the unique information, a storing unit (105) which stores the encrypted content, and a transmitting unit (107) which transmits the stored encrypted content in response to the transmission request from the on-vehicle player apparatus (20). The on-vehicle player apparatus includes a storage medium (208) which stores the received encrypted content, and a decrypting unit (209) which decrypts the stored encrypted content in response to a reproduction request given from outside.

  • Patent number: 7907064
    Abstract: An image-taking control section determines, based on information outputted from a location information obtaining section, whether a vehicle has entered a car park. When the vehicle has entered the car park, an image storage section stores, at predetermined time intervals, images of a view in a traveling direction of the vehicle, which images are taken by a vehicle-mounted camera. Image taking is terminated when the vehicle is parked at a parking space and a parking brake is applied. Thereafter, the taken images are transmitted via a transmission section to a mobile terminal held by a user. The user is allowed to easily recognize the parking position of his/her vehicle by viewing the images with the mobile terminal.
