Car stylist is successful already millimeter wave (MmWave) sensor is compositive in applying inside many cars cab.
One of these application are in can be being placed with sensor in condition of of all kinds illume, detect the member that the car mies wife takes a case, and no matter whether its are mobile. This can help car system detect stay in the children of unmanned guard inside the car or staff position, in order to undertake temperature is controlled.
Azcom Technology revealed sensor of AWR1642 millimeter wave to combine Azcom to have algorithm only, how can identify the personnel on seat to enter a case reliably. We with different speed, reach different environment (city, freeway) with cab (illumination, temperature) the condition undertakes driving, analysed different seat configuration.
Demonstrate in ours in, sensor will come down from scuttle suspension, front backlash (show) 1 times like the graph, although be in final installation,it is placed more possibly to be all round interior of seat back of a chair, rearview mirror or the place such as roof interior. Because millimeter wave can feel all sorts of material, include to make the material of car, because this installation is inside seat or roof when, pass feeling function to won’t produce change. All processing that include Azcom Technology to enhance a function move on sensor, and the graphical user interface on lead plane conduces to visible result.
Graph 1: Install the millimeter wave sensor on car scuttle
This uses the main challenge of the exemple is when engine open and car travel implementation detects adequately dovish sex. The combination of these two incident introduced a group of the signal that comes from several nonexistent in static setting oscillatory mode to interrupt. Stem from this reason, we designed a kind of new algorithm. This algorithm is not quite sensitive to coming from viatic vibration, and can detect all likelihoods that the member that the car mies wife enters a case are combined.
The member that my wife besides the car enters a circumstance to detect referenced design, we still apply and test and verify these enhance a function. Graph 2, 3, 4 and 5 it is a few snapshot that come from sample drive, and detect the graphic representation that the member that the car mies wife enters a case.
In the graph 2 in, when driving in the city back row seat is entered without personnel, algorithm detects without reason barrier. Statistical data presses the ratiometer of processing hardwood to calculate: This is used 6 Fps is in the exemple. In real product, the 2 class with inferior frequency are decision-making the tool can make detect become more dovish.
Graph 2: Back row seat is entered without personnel
In the graph 3 in, this algorithm detects successfully area 1 in personnel is entered, if red circle place is shown.
Graph 3: Back row seat detects personnel is entered
Graph the algorithmic accuracy when 4 side overweight uses different car cab. Through testing two kinds of different models, we are being entered with reliable staff was being shown when different speed travel detect circumstance.
Graph 4: Take in different car detect inside cabin personnel enters a case
The graph is shown 5 times expand for the design two 4 seat. Although this setting is more complex and have challenge sex more, but be in special after adjust and be being optimized, algorithmic expression and result of odd platoon setting are same beautiful.
Graph 5: 4 configuration
By right of a circumstance is entered to detect in personnel those who use a field know only and processing of TI platform, signal, radio frequency and embedded systematic design and the deep major knowledge that develop a field, azcom Technology provides services of a series of appreciation research and development, can aid your compose to build the product that enables millimeter wave, shorten greatly the product appears on the market time.
