Description

BRIEF DESCRIPTION OF DRAWINGS

[0020] The invention is explained by the schematic FIGURE of an intelligent electric bicycle control system.

[0021] The intelligent system includes a controller (I) to control electric bicycle engine (single board real time computer. which is designed on the basis of ARM architecture microcontroller and includes I/O devices for sensors and executive devices), the throttle handle (2), a sensor (3), the battery (4), the connection module (5) for transferring data on the movement and electric bicycles components status, as well as to exchange data with the mobile application and the remote control, the alarm (7), the light controller (8) to control light, turns and stop signals, and also audio signal, the controller (9) for collisions prevention and the bicycle computer (10), which is a device with an LCD screen to display the main indicators of the system which are connected by CAN bus. The intelligent electric bicycle control system, which consists of separated electronic modules with different functions, combined with consistent CAN bus, controlled and guided by the single-board computer on the basis of ARM architecture to work as a single system.

[0022] Controller (I) (for example “BLDC”) I is designed to control bicycle motor. It takes control commands and reverse connection from multiple sensors and regulators: mode switchers (not shown), the throttle handle (2), the sensor (3) (for example “PAS”). The sensor (3) and data from other sensors allow the most efficient use of the battery (4) and facilitate the efforts of cyclist.

[0023] Communication module (5) is intended for the exchange of data on the movement and electric bicycle components status, as well as to exchange data with the mobile application and the remote control. The main module of the battery is a collection of series parallel connected elements on the basis of lithium and control electronics, which performs a battery balancing, energy recovery when braking (recuperation), monitors compliance with best thermal regime of the battery and manages the process of optimal charging and discharging of the battery (6) (BMS).

[0024] The alarm (7) performs protective functions. In fact, it is the antitheft system that blocks the bicycle's electrical drive and turns on the siren when someone tries to steal it. This module also transmits to the user emergency messages via the communication module (5) using different communication channels.

[0025] The light controller (8) is designed to control light, turns and stop signals, as well as a sound signal, integrated into the overall system by using CAN bus. The user can also control the light in the manual mode. Other modules can also control the light signals in automatic mode in certain situations. For example, if the cyclist is entering the turn, tilting the wheel. gyro sensors (accelerometer) gives a command to the rotation indicator which automatically turns on and off.

[0026] The controller (9) for collisions prevention helps to prevent collisions and hits. To do so, it uses information from a front-facing radar microwave sensor and a rear radar sensor, or an optical device, depending on the modification. If another vehicle approaches to the dangerous distance from the back on a speed, a user receives a voice warning about the potential dangers. Or, for example, the cyclist, who is moving on the road approaches an obstacles or another vehicle.

[0027] The controller (9) for collisions prevention with the use of front-facing radar sensor receives information about the distance to the obstacle and the speed of convergence, making calculations. If the calculations show that it is necessary to slow down or make an emergency brake, the corresponding command is transmitted to the controller (I), and the speed of the electric bicycle is automatically reduced.

[0028] The bicycle computer (10), which is a device with an LCD screen is used to display the main indicators of the system, as well as to make some changes. Its main task is to provide the user with a “user-friendly” graphical interface. The bicycle computer (10) not is a critical component of the system, and in case of its failure or damage a user can continue the movement.

[0029] Under real conditions, the system is configured as separate modules connected by a power supply unit and a bus. The modules are located in different parts of the electric bicycle, in the internal cavities. The control instruments are located mostly on the steering wheel and on the external parts of the frame. For connecting modules and sensors sealed connectors are used, so as in the automotive industry. The module of the controller (I) is highly heated during workloads, so it is made of aluminum radiator case and placed externally on the electric bicycle frame.
