Embodiment Construction

[0044] The invention is schematically illustrated with the aid of an embodiment in the drawing and is described in more detail below with reference to the drawing.

[0045] exist figure 1 In the method steps according to the first exemplary embodiment of the invention for detecting an increased slipping state in a vehicle designed as an electric bicycle (also referred to as an electric bicycle or pedelec) are shown. In order to detect the current slipping state, in the example in a first step 110 the change in pedal speed Δn over a defined time period Δt is measured, or in other words the pedal acceleration is measured As can be directly understood, the pedal acceleration Correlates to the rotational speed of the driven wheel. Therefore, pedal acceleration In this example the sliding parameters according to the invention are formed. Alternatively, it is conceivable to detect the pedal acceleration directly via a gyroscope (rotational acceleration sensor) on the wheel. ...

Abstract

The method involves detecting a slip factor based on a rotational speed of a driven wheel, and detecting the motor torque, where the slip factor is detected as an alteration of pedal rotation speed over a turning rate sensor at the driven wheel. A pedal rotational torque is detected (130), and a drive unit is controlled based on the detected slip factor. A sum of the motor torque and the pedal rotational torque is controlled based on the detected slip factor. The slip factor is compared with a threshold value, and a slippage state of the driven wheel is determined based on the comparison. Independent claims are also included for the following: (1) a control device for a pedal-driven vehicle (2) a pedal-driven vehicle.

Description

technical field [0001] The invention relates to a method for regulating a pedal-driven vehicle, which has a drive unit and includes a pedal drive and a motor as auxiliary drive. The invention also relates to an adjusting device for such a vehicle and to such a vehicle having an adjusting device. Background technique [0002] In vehicles with a pedal drive and a motor as auxiliary drive, especially in two-wheeled vehicles with an auxiliary drive (so-called electric bicycles (electric bicycles) or pedelecs (electrically assisted bicycles), normal driving is understood as The motor torque follows the pedal torque. The motor torque can be either proportional to the pedal torque or approximately constant according to an intermediate value or attenuation assistance. There are therefore torque peaks at points in time at which the driver Apply maximum force to the pedals. This is entirely desirable, as it produces a natural driving feel. Problems then arise when the driven wheels o...
