Intelligent cockpit domain controller
The essence of cabin intelligence is based on the human-machine interaction scenario in the car cockpit, integrating driving information
and entertainment information modules to
provide users with an efficient, intuitive, and futuristic driving experience. The design appeal of intelligent cockpit is mainly to enhance the
driving experience of users, while ensuring the safety and comfort of driving, ultimately achieving the ultimate goal of cars as the third living
space for people outside of work and home scenes.
The intelligent cockpit domain includes three main components: HUD, Cockpit, and In Vehicle Entertainment (IVI).
HUD is a very practical feature that projects ADAS and some navigation functions onto the windshield, such as ACC, pedestrian recognition LDW、
Route reminder, intersection turning reminder, lane change reminder, remaining battery, driving range, etc. HUD will soon evolve into AR HUD,
becoming standard in the L3 and L4 eras.
Entering the L3 era, Driver Status Monitor (DMS) will become an essential feature, including facial recognition, eye tracking, blink count tracking, etc.,
which will be introduced into machine vision and deep learning algorithms. In the L4 era, V2X (Vehicle to Everything) is essential.
In addition, the flourishing development of multimodal interaction technology will greatly change the interaction mode between users and cars.
Voice interaction technology based on speech recognition function is becoming increasingly popular and commonly used for interactive operations
with IVI systems. Furthermore, the driver”s emotional state can be analyzed through voice communication. When the DMS system detects that the driver is drowsy,
the system can wake up the driver by playing music or releasing fragrance; The multimodal interaction technology for automotive cockpits based on multiple scenarios
will definitely redefine the development of human-computer interaction technology in the future.
The development of all these new technologies for intelligent cockpits will drive a surge in demand for cabin domain computing resources.
In the field of intelligent cockpit domain controllers, global Tier 1 manufacturers mainly include Bosch, Continental Automotive, Harman, Visteon, and Aptiv.
Chinese domestic enterprises mainly include Desay SV, Hangsheng, and Neusoft Ruichi
