A fully integrated center console is ubiquitous in modern cars, and a single display acts as the primary interface for the driver/passenger to interact with the vehicle. Users can interact with various menus by touch to access car navigation, radio, MP3 library, address book and weather forecasting system. Some luxury models are equipped with multi-touch capacitive sensors and capacitive buttons for a more cool interface. But unfortunately, the seat position, volume, air conditioning direction adjustment and other functions, but still generally use mechanical buttons or knobs for control.

“The modern automobile industry has made great progress in terms of vehicle design, engine performance, fuel efficiency, active safety, infotainment system, etc., but an interesting phenomenon is that the car center console has hardly taken place in more than 50 years. Sexual changes until the release of Tesla Model S.†Yan Goh, director of automotive product marketing for Asia Pacific at Atmel, said the Model S is equipped with a scalable 17-inch large-screen touch console that is “sporting†"This aspect indicates that the advanced capacitive touch function has begun to go down the altar and gradually become the standard for the low-end models. On the other hand, it also indicates the future direction of the car, that is, the car is no longer just a driving tool, but It will become a mobile intelligent information center that combines navigation, entertainment and security.
Atmel curved screen car center console AvantCar
The Atmel AvantCar, a curved-screen automotive center console that Atmel showed at CES 2014, may give some inspiration to automotive interaction designers. The AvantCar concept is a collaboration between Atmel and German automotive design company Germaneers GmbH. It shows a full-featured center console with two large streamlined touch screen displays pre-installed with Windows or Android operating systems.
The touch screen in AvantCar is not equipped with mechanical buttons, but integrates multiple capacitive touch buttons and sliders to allow users to operate basic applications in the car's center console, including GPS navigation systems, car air conditioners, radios or media player controls. Seat adjustment, etc.; the two screens can also interact with each other. After the user selects the menu on the lower screen, they can drag directly into the upper screen. In addition, AvantCar allows the driver to take advantage of various advanced touch functions. Automotive Local Interconnect Network (LIN) systems and microcontrollers personalize their interior lighting environments.
“The large-screen center console of the Model S still looks a bit blunt at the moment, and we hope that AvantCar will bring about disruptive changes.†Yan Goh believes that the future car center console will be more affected by various trends in the consumer market. It favors sexy streamlined design, smarter human-computer interaction, personalized interior lighting color, and the resulting wider seating and storage space. As a result, the entire AvantCar console has been designed with multiple Atmel core solutions, including XSense touch sensors, maXTouch controllers, QTouch technology, ACU Q100 certified MCUs, and LIN drivers for ambient lighting. Help the designer achieve the above goals.
"Streamlined touch screen display", "large capacitive touch screen", "close proximity sensing function and capacitive touch key / slider", "environmental lighting control" are the four highlights of AvantCar. For example, the flexible touch sensor XSense with metal mesh technology can be used not only for streamlined surfaces and edges, but also for replacing various mechanical switches and knobs on the center console, supporting glove touch operation and moisture-proof characteristics. The new center console gives a more stylish and elegant design.
The maXTouch controller with scan speeds up to 280Hz supports single or multi-touch from 2" to 12", supports single-layer unshielded sensors and gloves, and suppresses accidental such as hand-on touch screens. Touch, suitable for car center console display system, navigation system, wireless human-machine interface and rear seat entertainment system. According to Yan Goh, thanks to the ability to automate and intelligently switch between self-capacitance and mutual capacitance sensing, the maXTouch controller offers shorter response times, more precise touch and lower power consumption than other solutions on the market. Lower.
Automotive touch applications offer many opportunities for capacitive touch technology.
The proximity sensing function is ideal for driving at night. By sensing the hand being approached, the system can implement appropriate controls, such as switching the touch screen backlight to view GPS, broadcast control keys, and air conditioning. The QTouch library plays a vital role in helping developers easily embed capacitive touch buttons, sliders, pulleys, and close-range functions into microcontroller applications. According to Atmel, the royalty-free QTouch library provides multiple library files per device and supports a large number of touch channels (up to 64 channels; 256-level sliders or pulleys require only 3 channels), all library versions are available. The development process is simplified with a common application programming interface (API).
