Upsurge of sensor of automobile safety MEMS
From;    Author:Stand originally


Active and safe system increases stability of drive a vehicle

Generally speaking, involve car of automobile body pilot active and safe system includes: The car rolls control, car prevents slippery stability control, prevent adopt dead system, jockey apply the brake, embryo pressing is monitored, suspension is right car and road besides suit oneself adjust wait for a system, and MEMS sensor is having main effect in active and safe system. As a result of dimension of this kind of sensor small, reliability is high, can install them go up at car frame and suspension, use at monitoring the relative position of car and ground, allow a car to adjust suspension and in the car swerve, stability that weather does not offer the oldest rate when beautiful or road surface are not flat.

The electron stabilizes a program (domain of a ESP) is MEMS sensor fundamental application, this system measures the crab rate of car through angle sensor, and it and turn to the parameter such as horn and speed to undertake comparative, can detect oversteer or change direction insufficient such travel state, can turn in the car when or the roll effect that car swerve monitors a car in process of this kind of sudden incident, make car suspension can undertake adjustment, in order to retain the control of pair of automobile body stability, achieve the goal that prevents side to break up.

Blame contact can be offerred to measure fuel fluid continuously before essence of life measures electric specific item the series magnetoresistive sensor such as sensor of sensor of position of the door since sensor, section, steering wheel angle, market of this company China and Chen Zhen of chief inspector of sale ministry market express, the slip potentiometer technology that measures a technology to replace a tradition with the blame contact of magnetoresistive sensor is the tendency that sensor of car angle position develops. This company still rolls out sensor of atmospheric pressure of a small power comsumption recently, this product has number child output of processing of compensation, enlarge, number, data transmits 15 bit, highest precision is amounted to 0.05% , dynamic the biggest power comsumption only 1Ua, special agree with fetal pressing detects application.

New player and new application emerge in endlessly

With consumption electronic photograph is compared, car electron market has longer lifecycle, larger profit space, stabler shipment amount, accordingly although the threshold is higher also, still attracted a lot of comes from go to somewhere for shelter of consumptive electron market new entrant. Meaning law semiconductor (imitate of ST) Asia-Pacific area, power and Patrick Boulaud of inspector general of department of career of system of personal computer cable express: "Car electron application is us the key market 2008, big plant of ST and car of very much Europe has collaboration, having to car electron market understand well, derive application as what have systematic plan, we are new the acceleration sensor of generation will accord with the international standard attestation such as AEC-Q100 completely, the quality of the semiconductor device in ensuring the car applies adequately, dependability, side with 0PPM (0 blemish) target stride. " as we have learned, this new product already had sample at present, predict the 3rd season is OK this year batch offers money. Besides, ST future still plans measure the application such as control to roll out pressure sensor product in the light of oil.
