Digital displays that are bigger, more visually attractive, and with increasing features are becoming a key feature of vehicle cockpits
Bosch has developed new 3D display products, in response to the trend that cockpits of the future will play a key role in the interaction between drivers and their vehicles. The company noted that digital displays that are bigger, more visually attractive, and with increasing features are becoming a key feature of vehicle cockpits. The new products from Bosch use passive 3D technology to generate a realistic 3D effect that allows visual information to be grasped faster than when displayed on conventional screens, it said.
3D displays are the latest trend for vehicle cockpits, said Bosch. The display’s depth of field in a vehicle means drivers can grasp important visual information faster, whether from an assistance system or a traffic-jam alert, it added. These displays can also be especially useful when parking, where the rear-view camera image is more realistic, allowing obstacles to be detected earlier. When navigating streets, this 3D effect also plays a decisive role, as the spatial depth of the map display makes it immediately clear which building marks the next turn, Bosch explained. For its new display, Bosch makes use of a passive 3D technology, which works completely without additional features such as eye tracking or 3D glasses.
Bosch observed that eyes are responsible for 90 % of all human sensory perception, and the future is all about interaction between users and displays. The company has a display products portfolio that includes various applications from small and flat to large and curved, and sometimes in unusual shapes such as round or with trimmed corners. In addition to this, interaction can take the form of voice or touch control, with the latter also having the capability of haptic feedback. The future trend of autonomous driving, where drivers will let their autopilot do the driving, will see the human-machine interface (HMI) being crucially significant for the interaction between car and driver.
As displays increase in size, become more multi-purpose and intelligent, and feature voice and touch control, a larger amount of computing power is required, at times meaning more control units. At present, as many as 15 back-end processing units control the display and operating systems. However, Bosch uses a single cockpit computer to coordinate the entire HMI, and delegates all control functions to one central control unit. Fewer control units also results in lower weight, and reduced vehicle development times. Bosch further said that with over-the-air updates, the infotainment system can be kept up-to-date as simply as a smartphone.
Vehicle displays are subject to rigorous safety standards that are far higher than for consumer electronics, especially when it comes to temperature fluctuations and vibrations. An example would be that vehicle displays have to work flawlessly at temperatures ranging from -40°C to 120°C, and this over the vehicle’s entire service life. Bosch said that even in the event of partial failure, drivers have to be able to rely on a minimum amount of vital information at all times. The company added that its operating systems are tested thoroughly to make them fit for vehicle use.
Dr Steffen Berns, President, Bosch Car Multimedia, said displays are increasingly becoming interactive systems that can better anticipate drivers’ individual needs. There is huge business potential for Bosch here, since alerts that seem to jump out of the display are much more obvious and urgent, he added.
