摘　　要：现代汽车正向高速化方向发展，随着车速的提高，用软轴驱动的传统车速里程表受到前所未有的挑战。软轴在高速旋转时，由于受钢丝交变应力极限的限制而容易断裂，而且软轴布置过长出现形变过大或运动迟滞等现象。针对以上缺陷，本文设计基于单片机的电子式转速里程表的实现方案。With the rapid development of high-speed modem automobiles,the traditional speedometers with flexible drive shaft are subject to unprecedented challenges.The flexible shaft is easily broken down during its high speed revolution due to the restraints of alternating stress from the steelwire.Furthermore, large deformation and retardation will arise if the flexible shaft is too long.On the defects of the above defectse,this paper proposes a new kind of speedometer that is based on single-chip microcomputer.
