  • Power unit for motor vehicles
    Patent number: 5552988
    Abstract: A regenerative braking system in a motor vehicle determines a state of deceleration on the basis of the number of revolutions of a motor and an accelerator signal and performs a regenerative braking according to the state of deceleration. The regenerative braking system includes a revolution sensor for detecting the number of revolutions of a rotor of a vehicle driving motor and an accelerator opening sensor in a RAM stores discrimination data for discriminating between a regenerative braking mode and a drive mode on the basis of the number of revolutions of the rotor and the accelerator opening and also stores on-off duty ratio data of FETs in the regenerative braking mode and that in the drive mode.
    Type: Grant
    Filed: December 6, 1994
    Date of Patent: September 3, 1996
    Assignee: Honda Giken Kogyo Kabushiki Kaisha
    Inventors: Kenji Kawaguchi, Shoji Motodate, Masayuki Toriyama, Satoshi Honda, Takaaki Fujii, Toshiyuki Cho
