Beschreibung
Zusammenfassung:	A drive system for a four-wheel drive vehicle including a friction brake system includes a first motor and a second motor, a propeller shaft for transmitting power between a front-wheel side and a rear-wheel side, a first differential mechanism configured to divide output torque of the first motor between a left wheel on one side of the front-wheel side and the rear-wheel side and the other side, a second differential mechanism configured to divide output torque of the second motor between a right wheel on the one side and the other side, and a control device for controlling regenerative braking force related to the first motor and the second motor and friction braking force related to the friction brake system. The first and second differential mechanisms are configured such that the ratio of output torque allocated to the front-wheel side is 50% or more.
