在此回复挣积分 呵呵  我的积分全被同学用完了啊  无私的我啊  还得在这等45秒回复一个 楼主忍了吧  谁让我整好点到你的帖子呢

4.6.3 Electric power assistance
In small and medium size cars electric power steering (EPS) systems have become
widespread. They are applied to rack and pinion steering boxes and operate,
substantially, through an electric motor adding torque to the steering column,
or to the pinion directly.
Figure 4.18 shows the assembly including a modified steering column and
the detail of the electric motor with reduction gearbox.
The electric motor is regulated by an electronic controller, which again
has the function of generating an assistance torque proportional to the steering
torque.
The control system includes sensors capable of measuring steering torque,
vehicle speed, steering wheel speed and angle.
These data are used to calculate the optimum torque to be applied by the
motor; this value is a function of vehicle speed, to improve driver awareness of the
smaller steering torque values. The assistance is increased at the large steering
angles, typical of parking maneuvers and narrow turns, where actuation speed
is more important then sensitivity.
