Abstract: The design of the multi mode speed control system of a small intelligent patrol
line vehicle based on Freescale HCS12 microprocessor is introduced in this paper. The
speed control system is mainly composed of the DC motor circuit, the speed detection
module and the wireless communication module. And four speed models are obtained in
the speed control system. The overall structure of the speed control system and the
operation principles of the main modules are introduced in this paper. The software idea
and the block diagram of the software design are described. Experimental results show
that the small intelligent patrol line vehicle based on the multi mode speed control system
can be steadier and faster in response.
