Problems solved by technology

Therefore, when the engine speed decreases, the inertial torque of the motor functions as a reaction force torque, whereby the above-mentioned resistance is transmitted to the output member, and as a result, the vehicle may vibrate.

Embodiment Construction

[0041] refer to figure 1 An example of the vehicle Ve in the embodiment of the present invention will be described. figure 1The illustrated vehicle Ve includes a hybrid drive device (hereinafter simply referred to as a drive device) 4 having an engine (ENG) 1 and two electric motors 2 , 3 . The drive device 4 is configured to drive front wheels (drive wheels) 5R, 5L. The engine 1 is a conventionally known gasoline engine or a diesel engine, and is configured to output drive torque by combusting a supplied fuel-air mixture, and by stopping the combustion of the mixture, that is, stopping the supply of fuel, Accordingly, braking torque corresponding to friction torque, pumping loss, and the like can be output. The engine 1 corresponds to a "driving force source" in the embodiment of the present invention.

[0042] The first motor 2 is composed of a motor having a power generating function (ie, a motor generator: MG1), and is configured to control the rotation speed of the eng...

Abstract

The invention provides a driving force control device of a vehicle capable of suppressing the vibration of the vehicle mainly due to a decrease in the rotation speed of a driving force source when the rotation speed of the driving force source decreases in a state in which power supply of a motor outputting a reaction torque is stopped. When the rotation speed of an engine decreases in a state in which a non-driving range in which the supply of power to a first motor for outputting the reaction torque for transmitting the engine torque to the output member is stopped is set, the supply of power to the first motor or a second motor connected to the output member is resumed (step S4). A reduction torque for reducing an inertia torque based on a change in the rotation speed of the first motor is output from the first motor, or a reduction torque for damping the vibration of the output member generated in accordance with a change in the rotation speed of the engine is output from the second motor (step S6, step S7).

Description

technical field [0001] The present invention relates to a driving force control device for a vehicle including a differential mechanism in which a driving force source, a motor, and an output member are differentially rotatably coupled. Background technique [0002] Patent Document 1 discloses a hybrid vehicle including a first planetary gear mechanism through which a first rotation element to which an engine is connected, a second rotation element to which a motor is connected, and the third rotation element performs a differential action; the second planetary gear mechanism rotates through the fourth rotation element connected to the third rotation element, the fifth rotation element connected to the output member, and the sixth rotation element The elements perform a differential action; the first clutch mechanism connects any one of the first rotating element and the second rotating element to the sixth rotating element; and the second clutch mechanism connects the first...
