Embodiment Construction

[0160] First, based on Figure 1 ~ Figure 3 , an embodiment of the vehicle drive device of the present invention will be described.

[0161] The driving device for a vehicle of the present invention uses an electric motor as a drive source for driving an axle, and is used, for example, in figure 1 A vehicle with a drive system as shown. In the following description, the case where the vehicle driving device is used for driving the rear wheels will be described as an example, but it may also be used for driving the front wheels.

[0162] figure 1 The vehicle 3 shown is a hybrid vehicle, and has a driving device 6 (hereinafter, referred to as a front-wheel drive device) in which an internal combustion engine 4 and an electric motor 5 are connected in series at the front of the vehicle. The front wheels Wf transmit power to the rear wheels Wr (RWr, LWr) of a drive device 1 (hereinafter referred to as a rear wheel drive device) provided separately from the front wheel drive dev...

Abstract

An electric motor control means acquires a first motor target speed (MA2) and a first motor actual speed (MA1) of a first electric motor (2A), and a second motor target speed (MB2) and a second motor actual speed (MB1) of a second electric motor (2B); finds a first speed difference (DA) between the first motor target speed (MA2) and the first motor actual speed (MA1) of the first electric motor (2A), and a second speed difference (DB) between the second motor target speed (MB2) and the second motor actual speed (MB1) of the second electric motor (2B); finds first and second rotation control torques (SM1, SM2) on the basis of the smaller speed difference between the first speed difference (DA) and the second speed difference (DB); and finds a first motor torque (M1) of the first electric motor (2A) and a second motor torque (M2) of the second electric motor (2B) on the basis of the first and second rotation control torques (SM1, SM2).

Description

technical field [0001] The present invention relates to a vehicle drive device provided with a left wheel drive device for driving a left wheel and a right wheel drive device for driving a right wheel, and a control method for the vehicle drive device. Background technique [0002] Patent Document 1 describes a vehicle drive device that includes a left wheel drive device and a right wheel drive device. The left wheel drive device has a first electric motor that drives the left wheel of the vehicle, The first planetary gear type transmission on the power transmission path of the left wheel, the right wheel drive device has a second motor that drives the right wheel of the vehicle, and a second planetary gear that is provided on the power transmission path between the second motor and the right wheel. gear transmission. The first and second planetary gear transmissions are respectively connected to the first and second motors on the sun gear, respectively connected to the lef...
