Abstract

One embodiment provides a vehicle including: a first drive system configured to drive first wheels; and a second drive system configured to drive second wheels, wherein the first drive system includes: an electric motor; a motor controller; an engagement / disengagement unit provided between the electric motor side and the first drive wheels side; an engagement / disengagement controller; and a one-way power transmission unit provided between the electric motor side and the first drive wheels side in parallel to the engagement / disengagement unit, 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 side, wherein, when the vehicle reverses, a reverse driving force to reverse the vehicle is generated at least in the first drive system.

Description

Technical field [0001] The present invention relates to a front and rear wheel drive vehicle equipped with a front wheel drive device and a rear wheel drive device. Background technique [0002] Such as 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 a motor 103 that is an auxiliary drive source via a power transmission mechanism 104. [0003] The power transmission mechanism 104 includes a reduction mechanism 105 that inputs power from the electric motor 103, and a differential gear 106 that distributes the power output from the reduction mechanism 105 to the left and right rear wheels 102 and 103. The reduction mechanism 105 is composed of a reduction gear train consisting of a first gear 105a fixed to the output shaft of the motor 103, a second gear 105b meshing with the first gear 105a, and an input gear 106a meshing with the differentia...
