Current, the researchist of all kinds of car manufactures of China and automobile design specialized department, research university is carrying out a large amount of research for solving this difficult problem.

The patent of Zhejiang Jili Holding Group Co., Ltd, China publication number CN 101612893A, open day is on December 30th, 2009, denomination of invention: " brake method and the brake gear of mis-accelerator pressing during a kind of the brake ", this installs to measure the Das Gaspedal kinematic velocity and judges whether to brake and stop the driving engine operation, but when chaufeur wants that with shorter time this system may cause traffic accident during high-speed passing.

The patent of East China University, Chinese patent mandate publication number CN 102225691A, Granted publication day is on October 26th, 2011, denomination of invention: " a kind of vehicle throttle anti-misstep brake device ", this device starts brake so that the Das Gaspedal kinematic velocity is too fast, this device need to install centrifugal clutch device additional for Das Gaspedal, and practicality not and want that with shorter time this system also may cause traffic accident during high-speed passing when chaufeur.

Obviously, above-mentioned patent aberration that the chaufeur phenomenon of taking throttle as brake is stepped on has certain termination.But because it stops the too fast motion of judgement from footfeed, and chaufeur to overtake other vehicles and meet the anxious step on the accelerator speed of refueling in abrupt slope be also very fast very fast, above-mentioned patent is difficult to the very fast step on the accelerator speed of overtaking other vehicles and meeting the anxious oiling in abrupt slope of the throttle running velocity that mistake is stepped on phenomenon of taking throttle as brake and chaufeur and is distinguished, it will be very serious in case the program difference is wrong, causing error in judgement, its consequence.

Through long-term investigation and research, find, the automobile driver mistake has been stepped on following several situation by phenomenon of taking throttle as brake: the one, and automobile driver is stepped on phenomenon of taking throttle as brake unintentionally by mistake, mistake is trampled while causing self-propelled vehicle not stop to accelerate on the contrary, and chaufeur discovery in time self-correcting change into tramples brake; The 2nd, automobile driver is stepped on phenomenon of taking throttle as brake unintentionally by mistake, and mistake is trampled and caused self-propelled vehicle not stop to accelerate on the contrary, causes chaufeur to take for brake failure under flurried and phenomenon of taking throttle as brake is firmly slammed inflexibly; The 3rd, while being in an emergency, chaufeur goes out in a hurry foot fault and phenomenon of taking throttle as brake is stepped on to a pin steps on to die; Above three kinds of situations may not can except the first situation cause the accident, second the third situation tended to cause serious traffic accident.

At present, also do not have relevant invention and equipment energy entirely accurate to judge both at home and abroad and stop the aberration that the chaufeur mistake is stepped on phenomenon of taking throttle as brake.
