  • Temperature warning device and temperature warning method of friction element
    Patent number: 9897202
    Abstract: A temperature warning method of a friction element for issuing a warning depending on temperature of the friction element arranged between a power source and a driving wheel, includes issuing the warning when the temperature of the friction element exceeds an upper limit temperature, and making a period of time, from when the temperature of the friction element exceeds the upper limit temperature until when the warning is issued, longer when the temperature of the friction element exceeds the upper limit temperature for a first time than when the temperature of the friction element exceeds the upper limit temperature for a second or subsequent time.

  • Mode change control system for hybrid vehicle
    Patent number: 8688299
    Abstract: In a hybrid vehicle in which a mode change between an electric drive mode and a hybrid drive mode is carried out based on information concerning an operating condition and a driving status, an impairment of operability due to a change of the drive mode at a reverse travel of the vehicle is prevented. Upon a start of the reverse travel, the drive mode before the start of the reverse travel is continued at the start of the reverse travel.

  • Automotive front lower structure
    Patent number: 6070933
    Abstract: A novel automotive front lower structure is disclosed, in which the rear ends of left and right under covers are located symmetrically, so that the hot air in the drive unit mounting room is exhausted equally from the right and left rear ends of the under covers. Also, air spoilers arranged at the rear ends of the under covers improve the effect of negative pressure generation for an improved hot air exhaustion performance.
