Title:
電動機のトルクにより制動する車両及びその制御方法
Document Type and Number:
Japanese Patent JP3680734
Kind Code:
B2
Abstract:
The present invention enables a deceleration to be readily adjustable in the course of braking control with a torque of a motor mounted on a vehicle. In one embodiment, the vehicle has a power system including an engine 10, a motor 20, a torque converter 30, a transmission 100, and an axle 17 that are linked with one another in series. The transmission is a mechanism that changes over a gear ratio under control of a control unit 70 to vary the transmitted torque. The driver manipulates a gearshift lever in the vehicle to specify a desired deceleration by power source braking. The control unit refers to a predetermined map and specifies a combination of motor torque and gear ratio to attain the specified deceleration. In the course of braking control, the deceleration is corrected according to a step-on amount of an accelerator pedal in a range of play of the accelerator pedal. This arrangement facilitates minute adjustment of the deceleration by the power source braking.
