1. A corner module for a vehicle, comprising:
a front-wheel corner module configured to drive a front wheel of the vehicle, the front-wheel corner module including a front-wheel inwheel motor installed on the front wheel and configured to generate a driving force on the front wheel, and a friction braking device configured to generate a braking force on the front wheel;
a rear-wheel corner module configured to drive a rear wheel, and including a rear-wheel inwheel motor installed on the rear wheel and configured to generate a driving force on the rear wheel;
a driving information detector configured to detect driving information of the vehicle; and
an electronic control unit (ECU) configured to control the front-wheel corner module to form a friction braking force by using the driving information and to control the rear-wheel corner module to form a regenerative braking force,
wherein the front-wheel corner module uses the front-wheel inwheel motor that is provided with a lower specification than the rear-wheel inwheel motor,
the rear-wheel corner module has no friction braking device installed so that the rear-wheel inwheel motor is undamaged by heat,
the front-wheel inwheel motor is disposed inside a rim of the front wheel and lower than a central axis of the front wheel, the front-wheel corner module not having any other inwheel motor in an area above the central axis of the front wheel,
the friction braking device comprises one or more calipers that supply a braking force to a brake disc,
the one or more calipers are disposed above the central axis of the front wheel and disposed on an opposite side of the front-wheel inwheel motor,
the rear-wheel inwheel motor is disposed inside a rim of the rear wheel and has the same central axis as the rear wheel, and is disposed between the rear wheel and a lower end of a suspension, and
respective locations of the front-wheel and rear-wheel inwheel motors with respect to the central axes of the front and rear wheels are different from each other.
