Better still , by being able to tolerate temperatures that cause permanent magnets to break down , an induction motor can be pushed ( albeit briefly ) to far higher levels of performance-for , say , accelerating while overtaking or climbing a steep hill .
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 .
