A new generation of digital displays is becoming one of the main features of the cockpit of the vehicle, pursuing a larger size, a stronger visual effect, and more features. The digital display in the future of the cabin will continue the display and control functions on smart devices such as mobile phones and televisions, playing a key role in the interaction between the driver and the vehicle. Bosch’s new 3D display was officially created to cope with this trend. The product uses passive 3D technology to create realistic 3D effects that help drivers capture visual information faster than traditional displays. “Displays are gradually evolving into interactive systems that predict the individual needs of drivers,” said Dr. Steffen Berns, Global President of Bosch Automotive Multimedia, “for Bosch, there is tremendous market potential in this area.” According to Global Market According to Insights, by 2025, the global automotive display market will double from the current $15 billion (13.4 billion euros) to $30 billion (26.7 billion euros).
The 3D display is the latest development in the cockpit of the vehicle. On the movie screen, the 3D effect is mainly to enhance the entertainment of the film. But in vehicles, the meaning is completely different. “The stereoscopic view of the display helps the driver to capture important visual information faster, including assist system alerts and traffic jam reminders,” said Dr. Steffen Berns. “We let the vehicle reminder that it seems to jump out of the screen. It will be more intuitive and more urgent.” In addition, the more realistic rear view image during parking is good for detecting obstacles in time, helping the driver to better grasp the remaining space between the rear fender and the parking lot wall. This 3D effect also plays a decisive role in densely populated urban blocks, as maps with stereoscopic views give the driver a clear idea of which building should be turned. At the same time, Bosch’s new display is equipped with passive 3D technology, which eliminates the need for drivers and occupants to wear 3D glasses or use visual tracking technology.
The eye is responsible for 90% of the sensory perception of human beings. The on-board display that can simply display information is outdated, and deepening the interaction between the user and the display screen will become the future development direction. “Bosch is developing an infotainment system for any customer,” said Dr. Steffen Berns. In the future, human-computer interaction systems (HMIs) will play a key role in the interaction between the car and its driver, especially when the driver is using an automated driving system to run the vehicle.
The expansion of the display size, the versatility, the increased intelligence, and the development of speech recognition and touch control all put forward higher requirements for the back-end computing power of the display, which means that the display needs more control unit. Currently, up to 15 back-end processing units control and operate the display and operating system. Bosch uses only one onboard computer to coordinate the entire human-machine interface and integrates and implements all control functions using a single central control unit.
On-board displays must comply with strict safety standards, especially under temperature variations and vibration conditions, and safety standards should be much higher than other consumer electronics. The car’s display must function properly throughout the life of the car, whether it’s minus 40 degrees Celsius or minus 120 degrees Celsius. Even if a local failure occurs, the driver can rely on the necessary information obtained for safe driving. After thorough testing, the Bosch operating system will be suitable for all vehicles.
