  • Regenerative braking and torque converter control
    Patent number: 9187081
    Abstract: A method for controlling vehicle regenerative braking includes decreasing regenerative braking, provided a converter clutch is locked, such that regenerative braking torque reaches zero before a converter clutch opens due to vehicle speed reaching a reference speed; decreasing regenerative braking, provided the converter clutch is scheduled to open, such that regenerative braking torque reaches zero before the converter clutch opens due to vehicle speed reaching the reference speed; and braking the vehicle using wheel brakes.
    Type: Grant
    Filed: September 25, 2013
    Date of Patent: November 17, 2015
    Assignee: FORD GLOBAL TECHNOLOGIES, LLC
    Inventors: Zhengyu Dai, Yanan Zhao, Felix Nedorezov, Mark S. Yamazaki, Philip J. Wiethe, Jr.

  • Using driving behavior to determine gear changes of an automatic transmission
    Patent number: 8380406
    Abstract: A method for changing the timing of gear changes of an automatic transmission for a motor vehicle including repetitively updating a current value of a count whose value is a measure of driving behavior, performing an evaluation of driving behavior and updating the current value by a value determined from the evaluation, determining shift schedules that define the occurrence of a gear change to be produced by the transmission, and using the updated current value to establish from among the shift schedules a shift schedule that defines a gear change to be produced by the transmission.
