Abstract

One embodiment provides a vehicle (3)including: a first drive system (1) configured to drive first wheels; and a second drive system (6)configured to drive second wheels, wherein the first drive system (1)includes: an electric motor (2A, 2B); a motor controller; an engagement / disengagement unit (60A, 60B)provided between the electric motor (2A, 2B)side and the first drive wheels (1) side; an engagement / disengagement controller (45); and a one-way power transmission unit (50) provided between the electric motor (2A, 2B)side and the first drive wheels side in parallel to the engagement / disengagement unit (60A, 60B), and configured, at least, to engage the both sides when a reverse-direction rotational power is inputted from the first wheels side to the electric motor (2A, 2B)side, wherein, when the vehicle reverses, a reverse driving force to reverse the vehicle (3) is generated at least in the first drive system.

Description

technical field [0001] The present invention relates to a front-wheel-drive vehicle including a front-wheel drive device and a rear-wheel drive device. Background technique [0002] like Figure 16 As shown, in the vehicle 100 described in Patent Document 1, the front wheels are driven by a main drive source (not shown) such as an engine, and the rear wheels 102 are driven by an electric motor 103 as an auxiliary drive source via a power transmission mechanism 104 . [0003] The power transmission mechanism 104 includes: a reduction mechanism 105 for inputting power from a motor 103 ; and a differential gear 106 for distributing the power output from the reduction mechanism 105 to left and right rear wheels 102 , 103 . The reduction mechanism 105 is constituted by a reduction gear train consisting of a first gear 105 a fixed to the output shaft of the motor 103 , a second gear 105 b meshing with the first gear 105 a , and an input gear 106 a of the differential gear 106 . T...
