Speed control hump which is used for deceleration is divided into three parts. Left
view of the speed control hump is shown in Figure 2, in which 1 is the surface of the
road. 2 is the fixed speed control hump's inclined plane, 3 is the speed control hump
with it middle part connected with the iron yoke, which is the core of the linear motor.
4 is the speed control hump's back inclined plane, 5 is a yoke of iron connected with
