Title:
VEHICULAR ELECTRICALLY DRIVEN DEVICE
Document Type and Number:
Japanese Patent JP3683404
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To use electrically driven motors in an efficient rotational speed area by composing a brake of an electric machine connected to a repulsion receiving member, variably controlling a load of the electic machine, threby reducing a shock at the starting assist time and varying speed ratio between the electrically driven motor and wheels.
SOLUTION: A vehicular electrically driven device has bilaterally paired differential devices 8L, 8R, and a pair of electrically driven motors 91, 9R. An electric machine 14 is arranged for braking ring gears 8b of the differential devices 8L, 8R. In starting assist control, the electrically driven motors 9L, 9R are first started in the same directions in the state that a load of the electric machine 14 is zero. The load of the electric machine 14 is thus gradually increased, while braking force of the ring gears is gradually increased. Rotational speed thereof is decreased, while the rotational speed of a carrior 8d is increased by the equivalent rate. Driving force of the rear wheels is gradually increased. As a result, a deceleration ratio between the motors 9L, 9R and the rear wheels can be varied, and efficient rotational speed alone can be adopted.
