When performing emergency braking, the anti-mistaken stepping device controls a servo motor to drive a brake pedal through a DSP so as to precisely control the brake pedal pull speed and angle to precisely control the brake process of the automobile. The whole system has higher reliability and response speed; the DSP controls an automobile microcomputer controller to close a a throttle valve, so that the response speed is very fast; because the anti-mistaken stepping system is usually used for the emergency situation, the response speed of the system is very important, and the higher response speed further improves the safety assurance for the driver; the DSP serves as a signal processing controller, and an acceleration sensor and a radar sensor are directly connected with the DSP; compared with a single chip, the integration level of the DSP is higher, the CPU is faster, and accordingly the response speed and the reliability of the system are higher.
Description
Technical field
The present invention relates to automobile safety protective field, be specifically related to a kind of automobile accelerator mistake-stepping prevention device.
Background technology
At present, along with people's living standard improves constantly, car owning amount rapid growth, increasing people selects the trip of driving, and corresponding, traffic accident also increases thereupon.According to statistics, 70%～90% traffic accident all causes due to chaufeur maloperation, wherein because chaufeur throttle is stepped on the accident causing and accounted for again 12.6% of total accident ratio by mistake.According to NISSAN company, approximately having every year 7000 accidents in Japan is due to Das Gaspedal is stepped on and being caused as brake pedal by mistake.Because automatic gear car does not have pedal of clutch, cannot as manual automobile, utilize power-transfer clutch to cut off power, throttle and brake pedal are all used right crus of diaphragm control, therefore chaufeur is trampled throttle with right crus of diaphragm in motion, in the time of brake, need to lift right crus of diaphragm, shift to brake push down on the pedal automobile brake is slowed down.But in case of emergency, as having suddenly obstacle, front occurs, now because chaufeur is in high-pressure state, especially the just person of driving, be easy to, in flurried, throttle is treated as to brake, firmly step on the throttle, not only cause vehicle can not stop, rapidly speed-raising on the contrary, thus quite serious accident caused.
Accelerator stepping misoperation preventing technology, as the one of automobile active safety technology, can reduce or avoid chaufeur because wanting the sudden stop traffic accident that but mis-accelerator pressing causes.After this technology designs after deliberation, can be widely used in motor vehicles for civilian use, improve the personal safety guarantee of chaufeur.For this technology, Chinese scholars have had many design plans: current, existing a kind of pre-anti-error pedal (the Pedal Misapplication Prevention) technology of NISSAN company, this technology is mainly used in the mis-accelerator pressing while preventing from stopping.Last year, the Automotive News report in Europe, Toyota Company also will release a kind of new type of safe system, and wish that this technology will contribute to reduce the possibility of the high-speed crash accident causing because of mis-accelerator pressing.Dong-Chual Kang etc., by controlling the pressure of machine oil in transmission process, in the time that chaufeur causes automobile to accelerate suddenly because of mis-accelerator pressing, stop power to be sent on wheels, to play the object of protection chaufeur and vehicle.Yoshitake etc. have studied in different vision situations the age for the impact of mis-accelerator pressing, and have studied the probability that in time of driver's reaction and various situation, mis-accelerator pressing occurs.The design plan of domestic scholars is mainly divided into two kinds of forms.The first is mechanical type, utilizes the different of pedal pedal force while normally travelling from step on the accelerator in emergency circumstances, distinguishes two actions from pedal force.If be judged to be mis-accelerator pressing, it is invalid that device will be controlled this push down on the pedal, and produce interlock, the power of mis-accelerator pressing is converted into the power of trampling brake, reach the effect of braking.Also have design to increase the additional devices such as electromagnetic valve and control system on the basis of above-mentioned mechanical device, when excessive with convenient Das Gaspedal velocity of rotation, by solenoid valve shuts oil circuit, brake pedal left behind and played brake action simultaneously.The second is the electronic control system device based on micro controller system or car running computer.The angle that also has the default air throttle of car of designed system to open, the isoparametric threshold value of cireular frequency or angular acceleration, in the time exceeding separately threshold value, device judge driver fault misstepping on accelerator, and controls automobile brake deceleration simultaneously.
Sum up above-mentioned two class accelerator anti-false step on device, mainly have the following disadvantages: (1) device is developed according to theory of machines, Rule of judgment is single, cannot accurately judge the true object of chaufeur step on the accelerator, and due to individual fitness difference, the application force of pushes pedals is also different, and therefore the reliability of system and practicality are not high.(2) SCM Based electronic control package, Rule of judgment is also comparatively single, and accuracy and reliability are not high, and gordian technique is still immature, and major part only has conceptual design.As the sudden stop mis-accelerator pressing calibration package of the designs such as Yang Faquan, its single chip machine controlling circuit, this system principle is: in the time that chaufeur is trampled throttle, if the pedal that micro controller system is collected is trampled voltage signal and exceeded a reference value, carry out brake function and maintain 2s.
