Embodiment Construction

[0043] Hereinafter, one embodiment of the vehicle of the present invention will be described with reference to the drawings.

[0044] like figure 1 As shown, the vehicle V of the present embodiment includes mechanically independent main drive unit DU1 and sub drive unit DU2 . It should be noted that "mechanically independent" means that the power of one is not mechanically transmitted to the other through a transmission shaft or the like. In the present embodiment, the main drive unit DU1 outputs a main driving force to drive the front wheels FWR, and the sub drive unit DU2 outputs a sub driving force to drive the rear wheels RWR.

[0045] Vehicle V further includes battery BAT, voltage control unit VCU, and control unit CTR.

[0046] Battery BAT has a plurality of power storage cells connected in series, and supplies a high voltage of, for example, 100 to 200V. The electric storage unit is, for example, a lithium-ion battery or a nickel-metal hydride battery.

Abstract

Provided is a vehicle capable of further improving energy consumption efficiency. A vehicle (V) includes a main drive unit (DU1) configured to output a main driving force for driving front wheels (FWR); a sub drive unit (DU2) configured to output a sub driving force for driving the rear wheels (RWR); and a control unit (CTR) configured to control the output of the main drive unit and the sub drive unit. The main drive unit (DU1) includes an engine (ENG) and a main drive motor (MOT1). The sub drive unit (DU2) includes a sub drive motor (MOT2). The control unit (CTR) includes a driving force distribution ratio setting unit (75) configured to set a driving force distribution ratio between the main driving force and the sub driving force. When the drive mode of the main drive unit (DU1) is an engine drive mode, the driving force distribution ratio setting unit (75) is configured to set the driving force distribution ratio so that a distribution ratio of the main driving force is 90% or more.

Description

technical field [0001] The invention relates to a vehicle. Background technique [0002] Conventionally, there is known a vehicle that drives both front wheels and rear wheels, a so-called four-wheel drive vehicle. Four-wheel drive vehicles are often used in vehicles that require higher power performance and better road performance. [0003] On the other hand, due to an increase in environmental awareness in recent years, higher energy consumption efficiency is also required for four-wheel drive vehicles. Then, for example, Patent Document 1 discloses a vehicle including an engine that drives the rear wheels via a transmission, and a motor that drives the front wheels via a clutch that can be switched between an on state and an off state. , the vehicle is capable of switching between an engine two-wheel drive mode that drives only the engine, a motor two-wheel drive mode that drives only the motor, and a hybrid four-wheel drive mode that drives both the engine and the moto...
