  • Gear shift control system for automatic transmission
    Patent number: 9162673
    Abstract: A gear shift control system for vehicles is provided which mathematically calculates a rate of deceleration of the vehicle equipped an automatic transmission upon start of deceleration of the vehicle and inhibits the automatic transmission from upshifting or changes a permissible gear shift range of the automatic transmission as a function of the rate of deceleration of the vehicle, thereby ensuring a desired degree of braking force including an engine braking force while the vehicle is decelerating.
    Type: Grant
    Filed: August 8, 2013
    Date of Patent: October 20, 2015
    Assignee: SUZUKI MOTOR CORPORATION
    Inventors: Shuhei Kawamoto, Satohiro Yoshida
  • Ratio shift control system for an automatic transmission
    Patent number: 8734292
    Abstract: A ratio shift control system for an automatic transmission calculates the magnitude of a difference in temperature between a detected engine coolant temperature and a detected outside air temperature, which are detected by coolant and outside air temperature sensors, respectively, during one engine start of an internal combustion engine. Ratio shift in the automatic transmission is controlled based on the detected outside air temperature during the one engine start when the magnitude of the difference in temperature is equal to or less than a predetermined cold engine evaluation threshold.
