Design of the bus active speed control system based on ARM

From the bus active safety standpoint, this article designs the embedded system to control the speed of automobile in time without changing the original structure. The system selects STR712FR2 based on ARM7 as the microprocessor, able to control the automobile speed in accordance with the road conditions. The system has advantages in simple structure, low power consumption and practical function. The system function, the overall design and implementation procedure of the system, the software and hardware choice are analyzed in detail. Meanwhile, the initial validation of the system is carried out.
