A vehicle corner module for wheel-individual steering comprises a wheel portion, a vehicle portion and a steering mechanism. The steering mechanism comprises a steering motor and a gearbox. The steering motor is configured to rotate the wheel portion about a steering axis relative to the vehicle portion by way of the gearbox. The reliability and service life of such a vehicle corner module is to be increased. For this purpose, it is provided that the steering mechanism comprises two steering motors, each of which is configured to rotate the wheel portion about the steering axis relative to the vehicle portion by way of the common gearbox. Furthermore provided is a vehicle comprising at least one, preferably two or four, such vehicle corner modules.

A vehicle driving system including a driving/braking system including an in-wheel motor and an electromechanical brake installed in an inner side of a rim of a tire, a suspension system coupled to a rotational center shaft of the rim, and a steering system provided on an upper portion of the suspension system, wherein the suspension system includes a knuckle connected to the rotational center shaft of the rim, a plurality of first links each having one end connected to the knuckle, second links respectively connected to the other ends of the first links and the steering system, and a damper unit located between the knuckle and the steering system.
