Embodiment Construction

[0042] Hereinafter, the present invention will be described more specifically with reference to the accompanying drawings. figure 2 is a schematic diagram showing an example of a power train of a hybrid vehicle to which the present invention is applied. An engine 2 serving as a prime mover of the vehicle 1 and a motor generator 3 (MG2) are provided. Engine 2 and motor generator 3 ( MG2 ) are connected to wheels 5 via differential mechanism 4 . The engine 2 is a power device that converts heat energy into kinetic energy by burning fuel. For example, an internal combustion engine such as a gasoline engine, a diesel engine, or an LPG engine may be used as the engine 2 . Motor generator 3 includes a rotor 6 and a stator 7 . The motor generator 3 converts electrical energy into mechanical energy, and converts mechanical energy into electrical energy. That is to say, the motor generator 3 has both the function of a motor (that is, the function of generating power) and the funct...

Abstract

When speed is changed by a stepless transmission and a clutch is engaged, a variation in torque inputted into the clutch is suppressed. A controller for a vehicle drive device has a reaction force generation device for controlling the transmission ratio of the stepless transmission and also has the clutch provided in a power transmission route from the stepless transmission up to wheels, and in which torque capacity of the clutch is controllable. The controller has first input torque control means that reduces, while the torque capacity of the clutch is controlled, torque inputted via the stepless transmission to the clutch, and the torque reduction is made by controlling torque of the reaction force generation device.

Description

technical field [0001] The present invention relates to a control system of a vehicle drive device having a plurality of prime movers (drive power sources) for transmitting power to wheels. Background technique [0002] In recent years, a hybrid vehicle including an engine and a motor generator has been proposed in order to save fuel for driving an engine and reduce noise generated by engine operation and exhaust gas generated by fuel combustion. Such a hybrid vehicle is driven by controlling an engine and a motor generator according to the running state of the vehicle. [0003] Specifically, a hybrid vehicle can be driven by driving the engine in a rotation region where the engine combustion efficiency is excellent, or by stopping the engine while using the motor generator as an electric motor in a rotation region where the engine combustion efficiency is deteriorated. vehicle. Japanese Patent Application Laid-Open No. 2003-127681 discloses an example of such a control sy...
