Sensor and the modern automobile electron modern automobile electron from the electronic primary device which applies to the vehicle in the electronic system construction entered one the new stage which has essential to enhance.One of in which most representative core components is the sensor.

First, the automobile electron holds controls mentions with the safety system

First, the automobile electron holds controls mentions our country automobile industry growth with the safety system to be in the last few years rapid, the development tendency is very fierce.Therefore commented appeared some expert's forecast: The automobile industry has the possibility to surpass the IT industry, becomes one of Chinese national economy

most important pillar industries.Actually, the automobile industry growth will certainly to contain with the automobile industry correlation IT industry growth.

For example, although at present only occupies about 10%-15% in our country steam product neutron product

and the technical price value content, but the overseas automobile neutron product and the technical value content approximately is equally 22%, in the upscale passenger vehicle the automobile electron has accounted for above 30%, moreover this proportion in, unceasingly the fast growth, anticipated very quick will also achieve 50%.

The electronic information technology already became the new generation of automobile development direction the leading factor, the automobile (vehicle) the power performance, manoeuvring could, the safety performance and the comfortable performance and so on each aspect improvement and raisehigh, all will rely on the mechanical system and the structure and the electronic products, the information technology perfect union.

The automobile engineering expert pointed out that,The electronic technology development has caused the automobile product the concept to have the deep transformation.This also is the recent electronic information industrial field to one of automobile electron unprecedented attention

reasons.But, must point out, except some vehicles in the sound, the video frequency equipment, Che Yong corresponds, the guidance system, as well as the vehicle carries vehicles and so on in work system, network system the electronic installation essence changes few outside .The modern automobile electron from the electronic primary device which applies (including sensor, actuator, micro electric circuit and so on) to the vehicle in the electronic system construction entered one the new stage which has essential to enhance.One of in which most representative core components is the intelligent sensor (intelligent actuator, intelligence changes delivers).

In fact, the automobile electron has already experienced several development phases: Electric circuit monitor control builds which from the separation electron primary device, passed through the electronic primary device or the module adds the microprocessor to construct respectively independent, special-purpose, semiautomatic and automatic holds controls the system, now already enters has used the high speed main line (at present to have 5 kind of above main lines to develop use at least)

In unification exchange automobile movement each kind of electronic equipment and system data, realization synthesis, intelligent regulation new stage.The new automobile electron system is composed by each electronic control unit (ECU), may hold independently controls, simultaneously can coordinate to the whole movement optimum condition.For example for causes the engine to be at the best active status, needs from the inspiration cylinder air flow, the manifold pressure determination start, Again according to work link boundary parameters and so on the water temperature, air temperature calculates the basic distributive value, meanwhile must through the damper position transducer examination damper opening, the definite engine operating mode, then the control, the adjustment best distributive value, finally also need through the crank angular speed sensor monitor crank corner and the engine speed, finally calculates and sends out the best ignition opportunity the instruction.

This engine fuel injection system and the ignition integrated control system

also may with combinations and so on exhaust gas discharge supervisory system and starting system, constructs Cheng Keshi the motor car engine power and the torque maximization, but simultaneously fuel oil consumption and exhaust gas discharge minimizing intelligent system.

Also may lift a safe driving aspect the example, stemming from steady, safe driving need, only aims at four wheels to hold controls, and installed the braking besides the application massive pressure transmitter to guard against generally hugs installs (ABS) deadly, many passenger vehicles, including the domestically produced vehicle, additionally built electronic power distribution system (EBD), ABS+EBD to be possible time the maximum limit safeguard sleet weather driving stability.
