Arrived at the Mazda booth which is a little small. A new model painted on the vivid red "Soul Red Premium Metallic" which is the image color of Mazda in recent yearsDemioAnd a little special designAxelaThere is a place.


◆ "Axela" with automatic operation system
First of all, we will jump into our eyes, Axela Sports with a special design.


A plating silver line runs from the headlight to the fender.


The roof was also painted with black and red gradation paint, and the logo of "MAZDA 3" which was the Western name of Axela was given.


The reason for special painting is that this Axela is a vehicle equipped with an "automatic driving system".


At the side of the vehicle, the American traditional circuit "Mazda, Raceway, Laguna SecaThe image of the Axela that runs "is running, you can see the state clearing the corner with a clean line taking. This is, of course, running by automatic driving, but at the time of traveling, techniques such as "map matching" are used which keep track of the position of the car while communicating with the base stations installed in several places, It is supposed to trace the line faithfully.


If you are unfamiliar, it is a difficult circuit running even if you run it normally, but Mazda's automatic driving system seemed to be clearing so much. Mazda said there is no aim to make this automatic operation a fully automatic driving system like Google's automatic driving car. The place to work as an assistant to the driver such as danger avoidance and leave priority to the driver is "Human horse monsterIt seemed to be said that Mazda was committed to advocating.

◆ Automatically adjust the light distribution according to the situation "Adaptive · LED · Headlight"
It was demonstrated next to the booth that the camera reads the situation of the road and automatically adjusts the light distribution of the headlight "Adaptive · LED · Headlight(ALH) ". ALH is a system mounted on the high beam side, when sensing the presence of an oncoming vehicle or a preceding vehicle, turning off only a part of the headlight makes it possible to create a brighter light up environment without letting the opponent driver feel glare You can get it.


It makes it possible to arrange six LED lights arranged in an array. By controlling these one by one, you can freely change the light distribution pattern according to the situation.


The state where all the lights are on is here. It is a small LED, but definitely it was better to avoid direct viewing, so the performance as light is enough.


The range illuminated in all lit conditions is like this. It seems that we pursued brightness and natural light distribution by devising a lens cut.


I then turned off the two lights on the right side.


Then, only a part of the illuminated area changed to dark.


Furthermore, it is possible to use such as to turn off only one light and not only illuminate a small area.


If this system is put into practical use, it will be possible to always use the high beam without inconveniencing others. Originally, during night drivingUsing high beams is basicAlthough it is said to be, in fact it has been forced to make a low beam just to be concerned about the presence of the opponent, resulting in the situation that the visibility of pedestrians and the like has deteriorated. It was that ALH was the solution to solve such a problem. Although it is still unknown to be installed in commercial vehicles,A new model rumored to debut in the spring of 2015It is a place to worry about whether there is loading on it.

◆ New Demio
New demo which was just released at the end of September 2014 also attracted attention.


Efforts to enhance safety performance are posted.


One of the efforts is "head up concept" to eliminate the need to move the gaze largely during driving.


It separates the display such as a car navigation system from the operation unit and pursues ease of operation with a controller that is located on the side from which the hand is lowered from the handle and the visibility that allows information to be confirmed almost without distracting eyes from the road ahead. At the time of appearance there were also cases where complaints were heard Voice navigation and audio integrated system "MAZDA CONNECTImprovement seems to be added one after another.


Also equipped with "Active Driving Display" on the meter that displays speed, navigation information, etc. on a transparent panel.


When you put on the engine, the stored panel will start up.


Since the information displayed on the panel looks focused about 1.5 meters ahead of the driver, the movement of the line of sight and the focus adjustment of the eye can be reduced.
