The present disclosure relates to a control method for regulating the electric motor of an electric bicycle for push assistance for the electric bicycle. The control method comprises identification of activation of the push assistance by the cyclist. When activation is identified, the electric motor generates a torque for driving the electric bicycle as push assistance. Subsequently, an acceleration by the electric bicycle in the direction of the longitudinal axis of the electric bicycle is captured by means of a first sensor, wherein the acceleration results on the basis of a manual pushing or braking force of the cyclist. The captured acceleration is compared with an acceleration threshold value in a further step, wherein, in the event of the acceleration threshold value being exceeded, the electric motor is regulated on the basis of a change in the captured acceleration to adapt the torque.

Control method and apparatuses for push assistance for an electric bicycle

A method for training an automatic gear unit of a two-wheeled vehicle and/or a device, as well as a two-wheeled vehicle having such a device modifies an existing characteristic map for the control of the gear unit based on the individual user information. Optionally, it is also possible to set up a characteristic map for the control of the gear unit with the aid of the method in that the user information is recorded during gear-change operations and utilized for further automatic gear-change operations.

A method for ascertaining a wheel circumference of a driven wheel of a vehicle includes measuring a rotational speed of the driven wheel during a predefined time span, measuring an acceleration of the vehicle in the direction of the longitudinal axis of the vehicle during a predefined time span, determining a distance traveled by the vehicle based on the measured acceleration, and determining the wheel circumference of the driven wheel based on the measured rotational speed and the ascertained distance traveled.

A control method comprises at least one detection of activation of the pushing aid. When activation is detected, in the subsequent step a velocity of the electric vehicle and/or a constant starting torque are/is generated by actuation of the electric motor. The generated velocity of the pushing aid as a result of the actuation is dependent on the engaged transmission ratio of the gearshift. In order to adapt the velocity, the control method comprises sensing the current motor rotational speed of the electric motor and sensing the current velocity of the electric bicycle. The engaged transmission ratio is determined as a function of the sensed motor rotational speed and the sensed velocity. The adaptation of the velocity of the electric bicycle occurs in the subsequent step as a result of regulation of the electric motor as a function of the transmission ratio and the maximum velocity, which is not exceeded.

A method for braking a vehicle which is operable by a motor or by muscular power, in particular an electric bicycle. During a braking operation, a brake force influencing device is controlled by an electric brake pressure control device, and the brake pressure for the front wheel brake and/or for the rear wheel brake, and thus the brake force thereof, is increased and/or decreased. The brake pressure control device receives brake pressure signals in each case from a brake actuation detector for the front wheel brake and for the rear wheel brake, and an improved distribution of a total brake force on the front wheel and the rear wheel is effectuated which differs from the distribution that is effectuated by the driver.
