A vehicle comprises a chassis supported by wheels for moveably carrying the chassis in a driving direction, a steering wheel for turning a steering column around a rotation axis, and a steering angle sensor for measuring a rotation angle of the steering column with an encoder that is stationary to the steering column and with a magnet sensor that is disposed axially displaced from the encoder on the rotation axis. The encoder includes a first magnet with a top side directed to the magnet sensor and a second magnet attached to the first magnet opposite to the top side. The first magnet includes a recess starting from the top side, and each magnet is magnetized orthogonal to the rotation axis. The first magnet and the second magnet are displaced against each other in rotation direction. The recess has a depth lower than an axial thickness of the first magnet.
