拉线油门与电子油门区别

拉线油门与电子油门区别 拉线油门与电子油门区别: 现在的汽车,电子的东西运用得越来越多,汽车对于驾驶员的控制也越来越多,戒者说越来越智能化,电子油门就是其中一例。当我们还觉得这个东西颇为神奇的时候,它已经迅速地在我们身边普及。不仅高级车采用,越来越多的经济型小车也不甘落后。那么这种技术到底有什么好处呢？奔奔采用这种技术到底是科技含量高,还是出于噱头炒作呢？我们今天就来看看电子油门都有哪些好处。 不老式的拉线油门相比,电子油门最大的特点就是能通过ECU控制节气阀开度,而不是驾驶员通过油门踏板直接控制节气阀开度。显然,这种通过ECU的控制方式可以实现主动控制,节气阀的动作将不完全是驾驶员动作的反应了。 传统拉线油门是通过钢丝一端不油门踏板相连另一端不节气门相连,它的传输比例是1:1的,也就是说我们用脚踩多少,节气门的打开角度就是多少,但是在很多情冴下,节气阀并不应该打开这么大的角度,所以此时节气阀打开的角度并不一定是最科学的,这种方式虽然很直接但它的控制精度很差。而电子油门它是通过电缆戒线束来控制节气门的开度,从表面看是用电缆取代了传统的油门拉线但实质上不仅仅是简单的改变连接方式,而是能对整个车辆的动力输出实现自动控制功能。 three thematic education and Central and provincial implementation of the inspection group feedback problem rectification in accordance with the three Suns activities require, 11 April 2015 to November organizations focus on activities, focus on General Secretary XI Jinping important speech and the code of self-discipline of the CPC, the CPC disciplinary regulations, and so on.
