Abstract

In order to provide, for an electric vehicle equipped with two rotating electric machines and configured such that the rotating electrical machine which drives the air conditioner also is used to drive the vehicle wheels, a drive device with which it is possible to set the optimal range of possible use of the rotational velocity for each rotating electrical machine for driving the vehicle wheels, this drive device for an electric vehicle is equipped with: a first rotating electric machine the rotor shaft of which is linked to and drives an output member; a second rotating electric machine the rotor shaft of which is linked to and drives a compressor-connecting member and is linked to and drives the output member; a first engagement device capable of releasing the drive linkage between the rotor shaft of the first rotating electric machine and the output member; and a second engagement device capable of releasing the drive linkage between the rotor shaft of the second rotating electric machine and the output member.

Description

technical field [0001] The present invention relates to an electric vehicle drive that has an output member that is drive-connected to wheels and a compressor connection member that is connected to a compressor for an air conditioner, and that generates a driving force transmitted to the output member and the compressor connection member by a rotating electric machine. device. Background technique [0002] Regarding the vehicle drive control device as described above, for example, Patent Document 1 below discloses the following technology. In the technology of Patent Document 1, the rotor shaft of the rotary electric machine for air conditioners is drive-coupled not only to the compressor connecting member but also to the output member, whereby the driving force of the rotary electric machine for air conditioners is used to assist the wheels. A rotating electrical machine for driving, so that the vehicle can be driven. [0003] However, in the technique of Patent Document ...
