摘要： An electric pedelec bottom bracket drive includes a drive unit, a drive controller, and an ambient temperature detector. The drive unit includes a drive unit housing, a drive motor arranged therein, and a housing temperature sensor which measures a housing temperature. The drive controller supplies electrical drive energy to the drive motor and includes a housing temperature control module which is connected to the housing temperature sensor and which controls an electrical drive energy to not exceed a housing limit temperature. The ambient temperature detector is arranged to detect an air temperature outside of the drive unit housing and is connected to the housing temperature control module. The housing temperature control module limits a maximum electrical drive energy as a function of the air temperature when the housing temperature measured by the housing temperature sensor is above a control intervention limit temperature which is below the housing limit temperature.

摘要： Provided are a bicycle control system and a user verification method thereof, including a sensing module and a control module installed on a bicycle. The sensing module obtains a torque signal and an angle signal from a crank sensing component, further obtains a speed signal from a speed sensing unit, and outputs the torque signal, the angle signal, and the speed signal to the control module; the control module assembles the torque signal, the angle signal, and the speed signal into a signal sequence as a key to verify a user identity for the bicycle.

摘要： A power transmission unit is used for generating auxiliary driving force for an electric bicycle, and includes a motor, an input structure, a speed reducer, a case, a bearing, and a bearing support portion. The motor includes a motor shaft. The input structure includes an input shaft and configured to rotate along with the input shaft, the input shaft being caused to rotate by external force transmitted thereto. Thea speed reducer mechanism is configured to transmit a rotational power of the motor shaft while reducing a rotational speed. The case houses the motor, the input structure, and the speed reducer mechanism. The case includes a first divided part and a second divided part. The bearing is located inside the case. The bearing supporting portion, to which the bearing is attached, supports the speed reducer mechanism. The bearing supporting portion is attached to the first divided part.

摘要： Electronic bicycles may communicate with each other to provide a communal biking experience to their riders. The electronic bicycles may collect rider data about their riders and may adjust the output parameters of the electronic bicycles based on the rider data. For example, the electronic bicycles may identify a weaker rider of the riders and may adjust the output parameters of the weaker rider's electronic bicycle to minimize a difference in the operation of the weaker rider's electronic bicycle and the stronger rider's electronic bicycle. Additionally, a parent rider may establish rider restrictions on an electronic bicycle ridden by a child.

摘要： A force measurement sensor includes a peripheral portion, a central portion, and a first frame connecting an upper section of the peripheral portion to an upper portion of the central portion. The central portion includes a seat intended to receive the outer ring of a bearing in order to mount a shaft in rotation about an axis Z. The frame includes a core enclosed by two arms which are substantially parallel to one another, such that the upper section of the peripheral portion, the upper portion of the central portion, and the two arms form a parallelogram.

摘要： A method for changing a transmission ratio of an electrically controllable gearing of a bicycle, in particular of an electric bicycle, includes (i) measuring a pedaling frequency of the bicycle rider on the pedal shaft, (ii) measuring a pedaling force of the bicycle rider, and (iii) determining a gear change operating state on the basis of the measured pedaling frequency and on the basis of the measured pedaling force if the measured pedaling frequency is less than or equal to a lower frequency threshold value or is greater than or equal to an upper frequency threshold value, and/or the measured pedaling force is less than or equal to a lower force threshold value or is greater than or equal to an upper force threshold value. After determining the gear change operating state, a control signal is generated for the gearing according to the determined gear change operating state.

摘要： A control system for a vehicle including a first sensor that senses an acceleration of the vehicle and an electronic processor connected to the first sensor. The electronic processor determines whether a loading condition of the vehicle is detected and determines a first total mass of the vehicle using a first technique when the loading condition of the vehicle is detected. The electronic processor receives a first signal indicative of the acceleration of the vehicle from the first sensor, determines whether the acceleration of the vehicle is greater than zero, determines a second total mass of the vehicle using a second technique when the acceleration of the vehicle is greater than zero, determines a third total mass of the vehicle using a third technique when the acceleration of the vehicle is not greater than zero, and controls a function of the vehicle based on one of the total masses.

摘要： An auxiliary force control system and a method for a power-assisted bicycle are disclosed. The system has a sensing device, a mobile computing device, a first controller, and a second controller. The sensing device receives a riding torque and a riding speed. The mobile computing device generates a tuning factor via a first and a second ANN model. Personal data and historical riding data are input data of the first ANN model. Predicted grade outputted by the first ANN model, the personal data, and environment data are input data of the second ANN model. The first controller generates a final factor according to the tuning factor, a mode factor, and a gap-range factor. The second controller outputs a motor driver current according to a parameter of target output of the motor, which is generated based on the final factor, to the motor to drive the motor.
