Automotive circuit diagram is considered to the revolution in automotive technology development process, and the degree of automotive circuit diagram is counted as the important symbol weighing modern automobile level, is used to develop new model, improves the most important technical measures of automotive performance.Automaker thinks that the quantity of increase vehicle electronics, promotion automotive circuit diagram are the important effective means capturing future automobile market.
According to statistics, from 1989 to 2000, the ratio that on average on each car, electronics package is shared in whole Automobile manufacturing cost increases to more than 23% by 16%.On some Pullman saloons, use the quantity of one chip microcomputer to reach 48, electronic product accounts for more than 50% of integral vehicle cost, and the application of current Eltec has almost been deep into all systems of automobile.
Divide according on the impact of running car performance effect, automobile electronics can be summarized as two classes: a class is electronic control device for vehicle, electronic control device for vehicle will carry out with the use of, the i.e. auto electroincs of so-called " electric-mechanic control system " with mechanical system on car; They comprise driving engine, chassis, electrical control unit.Such as Jetronic, braking anti-lock control, anti-sliding control, polling power controlling, Electronic control suspension, electronic automatic transmission, electrical power steering etc., another kind of is vehicular automotive electronic device, vehicular automotive electronic device is the electronics package that can independently use under automotive environment, and it there is no direct relation with the performance of automobile itself.They comprise vehicle information system (car running computer), navigationsystem, auto audio equipment and tv entertainment system, Vehicular communication system, equipment for surfing the net etc.
The market in vehicle electronics future more trends towards safety, from the demand in market can find out people for the driving technique of safety and the attention rate of product very high.Achieve great progress in passive security technology---namely when automobile collides for driver and passenger provide technology and the product of protection; as the products such as crash sensor, air bag, safety strap, follow-up steering structure and metal sheet collision district and technology have saved the life of many people in automobile collision accident, and decrease personnel's injury.But the latest development direction is active safety, by adopting the technology such as radar, optics and ultrasonic transduter, the Distance geometry of measured automobiles and surrounding objects is close to speed during object.These data can be used for reminding driver to control the drive speed of automobile, avoid contingent collision accident.This information also can be used for control brake or steering swivel system, with automatic collision free.This collision avoidance system can reduce the expensive cost of global accident rate and car accedent.
Existing automobile is general all without anti-slip back system.
Automobile, when not drawn parking brake, if be on ramp, is easy to slip.
Interior nobody if vehicle backing is waited when slipping, then automobile likely can slip to korneforos, also may bump against body of wall and cause vehicle to damage, even may bump against pedestrian.
If vehicle backing has people in waiting when slipping, car owner dispersion attention may not recognize that vehicle slips, and so can cause further damage yet.
Summary of the invention

Step 3), the Das Gaspedal of automobile arranges Das Gaspedal inductor;
According to the cireular frequency of the acquisition of angular velocity sensor, step 4), judges that automobile is in forward travel state or fallback state;
According to the induction result of gear position sensor, step 5), if automobile is in fallback state, judges whether the selector of automobile is in retrogressing shelves;
Step 6), if the selector of automobile is not in retrogressing shelves, then judges whether the selector of automobile is in forward gear;
Step 6.1), if the selector of automobile is in forward gear, then judge whether gas is operated according to the induction result of Das Gaspedal inductor, if gas is not operated, the brake system controlling automobile carries out anti-slip back braking;
Step 6.2), if the selector of automobile is not in forward gear, the brake system controlling automobile carries out anti-slip back braking.
As the further prioritization scheme of vehicle anti-running method that the present invention is based on angular velocity sensor, described gear position sensor adopts Hall element.
As the further prioritization scheme of vehicle anti-running method that the present invention is based on angular velocity sensor, the model of described angular velocity sensor is ADXRS810.
As the further prioritization scheme of vehicle anti-running method that the present invention is based on angular velocity sensor, be also provided with display module, whether be in anti-slip back braking mode for display automobile.
