智能型1∶1电动助力车控制系统的研究

 为提高我国电动自行车厂家的市场竞争力，研制出一款新颖的智能型1∶1助力车。在详细阐述1∶1电动助力车的实现原理及其方案的基础上，提出采用经特殊设计的速度传感器和扭矩传感器采集人力脚踩速度和扭矩，并利用PIC16C712单片机作为信号处理与中心控制单元，以完成对人力脚踩输出功率的计算，并根据该功率的大小控制直流驱动电机的输出，实现真正意义上的1∶1助力。此外，为提高使用性能和安全性能，PIC16C712单片机还能够对该车的工作状况进行实时监测和控制。经测试表明：该车完全符合有关的1∶1技术标准，与同类车相比，该车在可靠性、使用性和性价比等方面呈现出明显的优势。

Research on control system of intelligent 1:1 electrical power assistant vehicle

To enhance the market competing capability of electrical bicycle factories in our country, an innovative electric vehicle with intelligent 1∶1 PAS (power assistant system) is developed. Through presenting implementation principle and design method of this electric vehicle, two special sensors (one is speed sensor, the other is torque sensor) are respectively designed to measure the speed and torque produced by the electric bicyclist. Then signals are transmitted to PIC16C712 MCU to calculate the input power and generate PWM to control the DC (direct current) electric motor and reliable 1∶1 power assistant function is implemented. Besides, the PIC6C712 MCU can real time monitor the electric vehicle’s working state to enhance operating performance and security. The testing results indicate that it can fulfill the concerned technical standard of 1∶1 power assistant electric vehicle. Furthermore, this vehicle has obvious advantages in reliability, operating performance and performance price ratio comparing to vehicle of the same kind.
