Title:
EVALUATION UNIT AND TWO-WHEELED VEHICLE FOR DETECTING A MOVEMENT BEHAVIOUR OF A WHEEL
Document Type and Number:
WIPO Patent Application WO/2019/020336
Kind Code:
A3
Abstract:
The invention relates to an evaluation device and to a system consisting of a two-wheeled vehicle and an evaluation unit, in which a movement variable which represents the movement behaviour of the wheel is generated based on the detection of sensor signals from a magnetic sensor. According to the invention, the two-wheeled vehicle, on which the claimed evaluation unit is provided, comprises at least one magnetic field sensor and at least one wheel with at least one magnet fixed thereon. The magnetic field sensor is fixed directly or indirectly to the frame of the two-wheeled vehicle, for example the magnetic field sensor is mounted on or in a housing of an electric drive system for an electric bicycle, which is mounted on the frame. It is also conceivable that the magnetic field sensor is accommodated in an energy supply unit for the electric motor or a control unit. In order to keep the distance to the magnets in the front and rear wheel as short as possible, the magnetic field sensor is preferably mounted close to the crankset, the rear wheel suspension or to the front wheel suspension. The speed or direction of rotation, a rotation, a lateral impact or a height impact of the wheel are determined as the movement variable. The steering angle of the front wheel can also be determined from the magnetic signal.
