汽车的转向控制(中文4200字,英文2500字)
控制系统稳定性是针对提高驾驶安全性提出的一系列措施中最新的一个。这个系统能够在40毫秒内实现从制动开始到制动恢复的过程,这个时间是人的反应时间得七倍。他们通过调整汽车扭矩或者通过应用汽车左侧或右侧制动,如果需要甚至两者兼用,来实现准确的行车路线。这个系统已被应用于奔驰S600汽车了。
稳定的机械自动系统能够在制动时发现肇端,并且在驾驶人员发现能够反应以前实现车辆的减速。
安全玻璃,安全带,撞击缓冲区,安全气囊,ABS系统,牵引力控制系统还有现在的稳定调节系统。汽车安全系统的连续升级,已经产生了一种为保护汽车所有者安全的设计模式。稳定调节系统帮助驾驶员从不可控制的曲线制动中解脱出来,从而避免了汽车的摆动滑行和交通事故。
利用计算机和一系列传感器,稳定调节系统能够检测到制动轮的打滑并且比人更快的恢复对汽车的方向控制。系统每百万分之一秒作出一次快速捕捉,以及断断汽车是否在按照驾驶员的路线行驶。如果检测到汽车行驶路线和驾驶员驾驶路线存在一个微小的偏差 ,系统会在瞬间纠正发动机扭矩或者应用汽车左右制动。过程的标准反应时间是40毫秒----人的平均反应时间的七分之一。

Spin control for cars
Stability control systems are the latest in a string of technologies focusing on improved diriving safety. Such systems detect the initial phases of a skid and restore directional control in 40 milliseconds, seven times faster than the reaction time of the average human. They correct vehicle paths by adjusting engine torque or applying the left- or-right-side brakes, or both, as needed. The technology has already been applied to the Mercedes-Benz S600 coupe.
Automatic stability systems can detect the onset of a skid and bring a fishtailing vehicle back on course even before its driver can react.
Safety glass, seat belts, crumple zones, air bags, antilock brakes, traction control, and now stability control. The continuing progression of safety systems for cars has yielded yet another device designed to keep occupants from injury. Stability control systems help drivers recover from uncontrolled skids in curves, thus avoiding spinouts and accidents.
Using computers and an array of sensors, a stability control system detects the onset of a skid and restores directional control more quickly than a human driver can. Every microsecond, the system takes a "snapshot," calculating whether a car is going exactly in the direction it is being steered. If there is the slightest difference between where the driver is steering and where the vehicle is going, the system corrects its path in a split-second by adjusting engine torque and/or applying the cat's left- or right-side brakes as needed. Typical reaction time is 40 milliseconds - seven times faster than that of the average human. |
