Automobile industry is producing heavy revolution because of the constant change of client demand. Suffer smartphone and other intelligence equipment to use habitual influence, consumer is a vehicle merely no longer to the requirement of the car, the intelligence that begins to search a kind to be able to live to be linked with its number at any time in the car however is driven by the experience. Traditional cockpit is evolving into one sort to seem the digital product at intelligent equipment, digital cockpit also because of this emerge as the times require.
Digital cockpit market is looked into
Digital cockpit is a series of indication technologies in car is compositive, basically include dashboard of information entertainment system, cockpit (appearance dial) , look up monitor (HUD) output with other data (like clock or temperature) monitor.
Before digital cockpit appears, the different data reading inside car is mutual independence substantially and the function is fixed. And digital cockpit can join many monitor together — for instance satellitic navigation and recreational system information can project dashboard or HUD, state information can show the journey or car to go up in information recreation screen. Because every monitor is OK,the visit comes from in the center of the data of the source, synchronous problem also got settlement. Actually, a of digital cockpit very crucial advantage is can configure afresh, this means a driver to be able to choose to show according to need what information and in which show on monitor. With electric car (EV) for exemple, the navigation that can choose to show odd course of development screen of centrally information recreation shows on the side, the parking space place that chooses to suit at the driver with benefit charges.
No matter the price of the car how, consumer hopes to obtain more numbers to experience inside the car. Be made as the car and rise of sale ceaselessly, also increasing to the demand of equipment of electron of compositive number cockpit.
Some earlier moment, the cost of production cockpit is car totle drilling cost about 2% to 3% . To gain luxurious, comfortable, safety and advanced information recreation experience, control of HUD, gesticulation, speech control, central controller, teleprocessing and turn to the technology such as control by large-scale in the digital cockpit that is used at multiplying to use a car. According to estimation, the cost of digital cockpit holds car totle drilling cost about 11% to 12% .
Current, cockpit dashboard (appearance dial) with information entertainment system demand of category of these two products is very exuberant, 2/3 what take digital cockpit market about. The analysis according to Grand View Research and forecast, 2020, dimensions of market of cockpit of global car number is 19.8 billion dollar, predict to came 2021 2028 will with of 8.8% compound growth of year of increase rate implementation.

Masses automobile group and Ao Di are A6 of Ao Di TT, Ao Di, RS 6 Avant, RS Q8 and Lanbojini the model such as Huracan offers fictitious cockpit, BMW provided system of digital direct seeding for its client. The cause that has manufacturer of a few cars additionally is to be in the economy end in mixing is offerred in the model drive advancedly supervisory system solution.
What crucial technology is propping up digital cockpit?
Car apparatus dial and monitor experienced heavy revolution in going 10 years, new digital cockpit can be in all information show on big screen together, the HMI that deserves to human nature is changed (man-machine interface) , the user controls traffic more easily.
The core that digital cockpit operates is car system between compositive, implementation method because of car manufacturer different and somewhat difference. Some used a system of powerful the computation central, regard collect as the line implement the monitor with different drive and control are unit, at the same time this computer central still needs to be in charge of coordinating periphery embedded system. Other manufacturer may deserve to have more powerful periphery system, emphasize central computation system lesser consequently.
No matter which are planted means, the car network of all sorts of types, be like CAN, LIN, FlexRay and aether net, final metropolis will come from the data that ECU and sensor differ in car introduce digital cockpit. To gain more comfortable user experience, the different compose system that car manufacturer still can provide tripartite is compositive in digital cockpit, these systems can be in fictitious after changing, through car management the program moves. Current, the digital cockpit of the mainstream on the market includes undermentioned and crucial technology and package mostly:
Look up show
Look up show (HUD) use in battleplan at first, also begin to be used at automobile industry now. HUD is a kind of transparent monitor, it can wait for data of speed, navigation, fraise data information to project directly in the driver’s line of sight, and won’t cause any interference to driving. Of course, stem from the consideration of cost, HUD basically is used at luxurious car at present. As the addition of client demand, one class supplier (Tier1) had planned to be mixed in commercial vehicle by HUD of arrange of the upside that use a car.
The HUD of type of 3 kinds of technologies basically was used at present in the car, namely: C-HUD (Combiner HUD) , W-HUD (Windshield HUD) and enhance reality (AR) HUD. Long-term in light of, the future of HUD will forward 3D HUD, sound controls HUD and development of laser HUD direction.

These systems not the position that be confined to indicates a place or individual, they still can offer around hotel, cafeteria, hospital, gas station, traffic to embrace, the similar message such as first line, use all sorts of machine study (ML) algorithm undertakes analyse and be optimizinged. In digital cockpit, navigation information can show in HUD or car other indication sound / on the screen of video information. No matter why be planted plan, these line of sights that information Dou Yingfei often stands by a driver, so that be gotten easily when car drives.
Intelligence is warm connect air conditioning (HVAC) controller
Nowadays, every car was installed beforehand central heating, ventilated with air conditioning system. Previously, the adjustment of temperature is finished mostly through knob. Now, this one function is in by installation the comprises by hot sensor automatic temperature controller inside the car is replaced. Hot sensor is detecting after the temperature outside the car, transmit data can make up Cheng controller, next by can make up Cheng controller to adjust the temperature inside the car according to algorithm. Digital cockpit is compositive the control function of HVAC, drive the thermoregulation that can realize cockpit easily through speech control by personnel.
Intelligent speech assistant
From control frequency / video information arrives the multinomial function that governs a car, intelligent speech assistant allows driver and passenger to avoid carry execute multinomial control mission. Be in the United States, car speech is additional use more welcome than the smartphone. Embedded the use of speech support system will car drive promote a brand-new standard by the experience.
Deepness of have the aid of learns algorithm, the natural speech processing of car cockpit and command control already were dummy no longer, be based on artificial intelligence (AI) the application that technology of intelligent speech recognition had materiality. For instance, the operating system of couplet net car that the company such as apple and cereal song develops is patulous / use a program, can pass USB or blue tooth / WiFi join displays screen to dashboard. Among them, the Android Auto of malic CarPlay and cereal song is special develops to operate car interconnection system two application program. It is reported, manufacturer of more than 70 cars is using Android Auto, manufacturer of more than 50 cars uses CarPlay to regard intelligent speech assistant as the system.
Digital appearance dial
Digital appearance dial offers all sorts of trends to drive for the driver information, the revolution counter that includes a tradition shows, the function shows, the course plans to pursue or show backsight to photograph the video that resembles a head to wait, so that the driver can monitor in real time the multinomial function index of the car, reduce accident risk. In digital cockpit, the driver can define the information that every monitor in digital appearance dial shows oneself according to his be fond of.
Digital cockpit aims to digitlize the whole cockpit in couplet net car, issue generation car monitor to will be given priority to in order to touch screen. The progress of artificial intelligence technology extended the control pattern of digital cockpit greatly, gesticulation and speech control are first selection. The compositive implementation of these technologies between driver and car without seam interactive, the driver’s eye can be centered on road all the time, in obtain while brand-new user experiences, enhanced the security that car drives considerably.
Digital cockpit develops ” core ” motivation
The development of technologies of afore-mentioned digital cockpit key and business are used, the ode that cannot leave rock-bottom semiconductor technology can, this one domain also became contend of manufacturer of chip of each old car electron advocate competition ground.
Texas Instruments (TI) the AWR1443 parts of an apparatus of the company can identify signal relaxed and compositive in digital cockpit.
