Firmware implementing of a dual-wheel drive electrical bicycle

The goal of this project is to design and build a dual-axis drive system for an electric bicycle. The computerized control for the electric bicycle utilizes a firmware-based system, with the vehicle´s electronic control unit (ECU)and most of the signal processing circuits implemented using a Programmable SoC (PSoC). This special dual-axis driven electric bicycle has many advantages over electric bicycles currently available on the market. To be able to have both wheels drive the vehicle simultaneously, the speed controller must be designed with a very high degree of accuracy so that it has the ability to compensate for speed difference that might exist between the front and rear wheels. In addition, both wheels have breaks and kinetic energy recovery for decelerating or downhill riding. The vehicle has automatic cruse capabilities and can automatically switch to single front or rear wheel drive at medium or high speeds. This saves power and avoids any single motor driver overheating because of long term driving.
