This scheme adopts Renesas R8C single-chip microcomputer. The control part of the main system has the identification of acceleration/brake information. According to this information, the three-phase motor is controlled, and the battery voltage and overcurrent can also be detected. An electric bicycle is a special bicycle that uses a battery as an auxiliary energy source and has two wheels, which can realize human riding, electric or electric assisting functions. According to the national standards for the design of the top speed, empty car quality, size specifications, electric bicycles belong to the non-motor vehicle management category, should have the following five characteristics: must have the pedaling function, the battery is only used as an auxiliary energy; must have Two wheels; the design speed is no more than 20 km / h; the weight of the whole vehicle is not more than 40 kg; the width of the tire (in the tire) is not more than 54 mm. The model of the electric bicycle is the TD (electric bicycle type of special bicycle type). Although it has the appearance characteristics of ordinary bicycles (even with the appearance characteristics of motorcycles), the main thing is that it is installed on the basis of ordinary bicycles, and controls parts and displays such as motors, controllers, batteries, turning brakes, etc. Mechatronics personal transportation of instrumentation systems.
