ABC, its English full name is Active Body Control, namely active automobile body controls a system. We know, when suspension when the system is better, can obtain very good drill to charge a sex, it is especially when high speed travel, be helpful for the stability of automobile body, but when should encountering poorer road surface, its are comfortable the gender cannot get assuring, and of pensile system set softer when, although got better comfortable sex, but hold accuse a gender to drop somewhat again, look up quickly for instance, phenomenon of brake dot first class is more apparent. And the occurrence of ABC overcame pensile set comfortable sex and hold accuse the contradiction between the gender, utmost ground is close to consumer to be in to car the requirement of this two respects.
Pattern of traditional suspension system work basically is to pass the automobile body of massiness to beat, push press hydraulic pressure oil, restrain the vibration of automobile body through damp vibrating absorber, draw jumpy energy by helix bedspring, this kind of completely passive means has a lot of insufficient place. And ABC system passes the wheel with the slightest reaction and automobile body act, make in time before any large automobile body are oscillatory to suspension system adjust, maintain the balance of automobile body.
Active automobile body controls systematic part / structure
ABC system makes a car right list, a simple move or action, yaw, jumpy the control with automobile body height more can rapid, accurate. The list of automobile body is little, change of wheel extroversion angle is little also, tire maintains as perpendicular as the ground contact with respect to can better land, make tire rises to the adherent force of the ground, make a movement in order to fill minute of drive that produces tire use. In addition the loading capacity of the car changes anyhow, the car can maintain certain automobile body altitude from beginning to end, so the geometrical relation of suspension also can ensure changeless. ABC system can get used to all sorts of road surface circumstances well, although be in bumpy place, the drill that also can keep advantageous accuses gender, comfortable sex and directional stability.
What put forward active automobile body the earliest to control a concept is LEXUS, in fact it just is the helix spring that uses common suspension changed air spring merely, added a simple automation unit, relative to Yu Fu's miscellaneous road surface circumstance, still have its limitation. Later French research and development the suspension with a stronger adaptability, it is now beautiful 607, the hydraulic pressure that uses on Xue Tielong C5 is active and pensile, he can divide 5 paragraphs to adjust avoid shake implement damp force (namely soft hardness) , opposite LEXUS is a very great progress. But the ABC that solve those who get used to a problem above all truly or runs quickly, he is with air pressure of pump adjustment air adjusts of pensile damp force, accordingly, the adjustment that he can not have paragraph of class is pensile soft hardness, get used to all sorts of road surface elements thereby.
