20、nd safety of driving. 第 3 页 随着世界能源危机的持续，以及战争和能源 -石油的消耗及汽车饱有量的增加，能源在一天一天下降，终有一天它会消失的无影无踪。石油不是在生资源。所以必须在石油耗净之前找到一种代替品。随着科技的发展社会的进步，有人发明了电动汽车。电动汽车将成为人们最为理想的交通工具。 世界 在发展各各方面都取得丰硕成果，尤其是随着汽车电子技术和计算机以及发展迅速的信息时代。电子控制技术在汽车上得到了广泛应用，汽车上应用的电子装置越来越丰富，电子技术不仅用来改善和提高传统汽车电器的质量和性能，而且还提高了汽车的动力性、燃油经济性、可靠性以及废气排放的净化性。汽车上
21、广泛使用电子产品不仅降低了成本，并且减少维护的复杂性。从发动机的燃油喷射点火装置、进气控制、废气排放控制、故障自诊断到车身辅助装置都普遍采用了电子控制技术，可以说今后汽车发展主要以机电一体化。汽车上广泛采用的电子控制点火系统主要有电子控 制燃油喷射系统、电子控制点火系统、电子控制自动变速器、电子控制防滑（ ABS/ASR）控制系统、电子控制悬架系统、电子控制动力转向系统、车辆动力学控制系统、安全气囊系统、主动安全带系统、电子控制自动空调系统、导航系统还有 GPS 等。有了这些系统汽车响应敏捷，使用功能强，可靠性高，既保证发动机动力又降低燃油的消耗，而且又满足排放法规的标准。 汽车是现代人必不可
22、少的交通工具。而电动汽车给我们带来无限乐趣外还能给我们劳累一天的身心得以放松。就拿自动变速器来说吧，汽车在行驶时，可以不踩离合器踏板，就可以实现自动换 档而发动机不会熄火，这样有效的提高驾驶方便性减轻驾驶员的疲劳强度。自动变速器主要由液力变矩器、齿轮变速器、油泵、液压控制系统、电子控制系统、油冷却系统等组成。电子控制的悬架主要是用来缓冲路面对车身的冲击力以及减少振动保证汽车平顺性和操纵稳定性。当汽车行驶在不平坦的道路时汽车能能根据底盘和路面高度自动调整。当车高比设置的高度低时，就向气室或油缸充气或充油。如果是相反，就放气或泻油。从而保证汽车的水平行驶，提高行驶稳定性。可变力动力转向系统因能显著
23、改变驾驶员的工作效率和状态，所以在电动汽车上广泛使用。 VDC 对汽 车性能有着至关重要的作用它能根据需要主动对车轮进行制动来改变汽车的运动状态，使汽车达到最佳的行驶状态和操纵性能，并增加了汽车的附着性，控制性和稳定性。除了这些之外 4WS、 4WD 的出现大大提高了电动汽车的价值与性能同步提升。 ABS 具有减少制动距离并能保持转向操作能力有效提高行驶方向的稳定性同时减少轮胎的磨损。安全气囊的出现在很大程序上保护了驾驶员和乘客的安全，大大降低汽车在碰撞时对驾驶员和乘客的缓冲，以过到保护生命安全的目的。 智能电子技术在汽车上得以推广使得汽车在安全行驶和其它功能更上一层楼。通过 各种传感器实现自动驾驶。除些之外智能汽车装备有多种传感器能充分感知交通设施及环境的信息并能随时判断车辆及驾驶员是否处于危险之中，具备自主寻路、导航、避撞、不停车收费等功能。有效提高运输过程中的安全，减少驾驶员的
