Abstract: A method for ascertaining a state of operating dynamics of a bicycle. The method includes: providing signals regarding an acceleration in at least one spatial direction and regarding a rate of rotation about at least one spatial direction, with the aid of an inertial measuring device; providing speed signals of an incremental encoder; and ascertaining the state of operating dynamics on the basis of an estimation method, in light of the provided signals; the current riding state being ascertained, and in the case of a dead stop of the bicycle as a current, ascertained riding state, substitute speed signals being provided in place of the speed signals of the incremental encoder, in order to estimate the state of operating dynamics for the estimation method.

Abstract: A method for determining a speed value of a single-track vehicle, in particular an eBike, is disclosed. The vehicle has at least one acceleration sensor and one rotation rate sensor. The method includes (i) measuring the acceleration of the vehicle in at least three directions using the acceleration sensor, (ii) measuring a rotation rate of the vehicle about at least two rotation axes using the rotation rate sensor, (iii) determining a driving situation of the vehicle based on the measured accelerations and rotation rates of the vehicle, and (iv) determining the speed value of the vehicle using a system of equations describing the kinematics of the vehicle, the determined driving situation and the measured accelerations and rotation rates of the vehicle.
