In conclusion, we know after the front suspension optimized, the front wheel alignment parameters is more reasonable. The variation of tread is minished so that the abrasion of the tire is reduced. And also the vehcile keep some understeering characteristic after front suspension optimized.

最后总结出优化之后的前悬架使得前轮的定位参数更加合理，减小了轮距变化量，从而降低了轮胎磨损，并保证了样车具有一定的不足转向特性。

"The steering-knuckle arm, attached to the front wheels, are therefore forced to swing the wheels to the right or left on their pivots." From here follows the success story of the FWD concept ( understeering).

于是，与前轮相连的转向节臂使车轮在其轴线上左右转动。前轮驱动（转向不足）概念的成功就在于此。

The analysis results showed that the instantaneous oversteering or understeering of the vehicle can be reduced by the control of the rear-wheel steering angle to enhance the dynamic steering stability.
