The system also observes overtaking rules and speed limits .

系统还能观察超车换道规则和最高限速。

Firstly to promote the development of environmentally friendly and road car-relevant technologies in formula one racing ; and secondly to aid overtaking .

第一是促进环保和一级方程式赛车相关技术的发展；第二是帮助超车。

At high speeds , for example , they do not lose torque as quickly as a permanent-magnet motor would . That helps during overtaking .

在高速行驶中，磁抗发动机不像永磁铁发动机那样快的失去扭矩，这在超车时候很有用。

That is because unlike petrol engines , which need to rev up before producing the torque necessary to budge a vehicle from a standstill or accelerate it quickly from a cruising speed , as in overtaking , electric motors provide full torque at the first touch of the accelerator pedal .

这是因为汽油机需要达到一定的转速后，才能产生足够的扭矩来起动静止的车辆或由巡航加速超车，但电动机在踩下加速踏板的瞬间就可以输出峰值扭矩。

Even as ford 's momentum of the past two years suggests it can keep outpacing larger rivals such as toyota and general motors to help meet its ambitious goals , it must keep an eye on the overtaking lane .

尽管过去两年的增长势头表明，福特能够继续在速度上超过丰田（toyota）和通用汽车（gm）等规模更大的竞争对手，以帮助实现其远大目标，但同时，该公司必须要时刻留意“超车道”。
