Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Multimedia entertainment system, method and the vehicle of vehicle according to an embodiment of the present invention are described below in conjunction with attached drawing.
Fig. 1 is the structural block diagram of the multimedia entertainment system of vehicle according to an embodiment of the invention.
As shown in Figure 1, the multimedia entertainment system 100 of vehicle according to an embodiment of the invention, comprising: communication interface
110, system on chip 120 (SOC) and controller 130.
Wherein, communication interface 110 is used to receive the multiway images signal of full-view camera 200 (CAM) transmission.System on chip
120 are connected with communication interface 110, for generating panorama according to multiway images signal after entering working condition by sleep state
Image.Controller 130 is connected with system on chip 120, for after receiving the trigger signal, exiting standby mode, and wake up piece
Upper system 120, so that system on chip 120 enters working condition by sleep state.
Full-view camera 200 includes multiple cameras, as shown in Figure 1, including the outer front, rear, left and right four direction of collecting vehicle
Four cameras.In this way, panoramic picture can see the case where front, rear, left and right four direction outside vehicle.
Communication interface 110 includes but is not limited to serial and unstrings module (SERDES), in this way, adopting to full-view camera 200
The multiway images signal that collects carries out being sent to system on chip 120 serially and after unstringing.System on chip 120 includes: modulatedemodulate
Circuit (MODEM) and power management integrated circuit (PMIC) are adjusted, modulation-demodulation circuit is for handling multiway images signal, so that piece
Multiway images signal is spliced into full-view image by upper system 120.Power management integrated circuit is used to control the work of system on chip 120
Make state.
In specific example, system on chip 120 integrates modulation /demodulation for example, by using the system on chip 120 for high-pass platform
Multiway images signal is directly connected with system on chip 120, to save external panorama processing module, is such as saved by device (MODEM)
External DSP, FPGA etc. have been removed, and has eliminated the serial of external panorama processing module and module (SERDES) etc. of unstringing.
System on chip 120 uses high-pass platform, thus showed with outstanding stand-by power consumption, it can be in vehicle stall state
It is lower to be therefore quickly waken up into Low-power-consumptiodormancy dormancy state.Another reason of high-pass platform is used to integrate modulation /demodulation
Device (MODEM), and power consumption performance is low under standy operation mode, and return speed is fast, thereby may be ensured that multimedia recreation
System 100 can be with quick response.
Trigger signal includes vehicle power on signal and wake-up signal, wherein controller 130 is receiving vehicle power on signal
Or when wake-up signal, working condition is transferred to by standby mode, and system on chip 120 is notified to wake up.That is: more under original state
Media entertainment systems 100 handle dormant state, when vehicle receives ACC (power on signal)/WAKE signal (wake-up signal), control
Device 130 notice system on chip 120 can be waken up rapidly, after system on chip 120 enters working condition by sleep state, so as to
To handle the splicing operation of full-view image at once.
It is understood that system on chip 120 is in sleep state under original state, controller 130 is in low-power consumption
Standby mode.
In addition, system on chip 120 is also used to after receiving and reversing gear signal, pass through display screen (multimedia entertainment system 100
Middle control display screen) display full-view image, that is to say, that until gear is switched to reverse gear by user or user is by lower section
After coherent video switch key on disk, corresponding full-view image will be shown immediately on a display screen.
As shown in Fig. 2, in one embodiment of the invention, the multimedia entertainment system 100 of vehicle, further includes: wireless
Communication module 140, wireless communication module 140 are connected with system on chip 120 and controller 130 respectively, and wireless communication module 140 is used
In when receiving the remote request signal of mobile terminal transmission, interrupt requests are sent to controller 130, so as to controller 130
Standby mode is exited, and wakes up system on chip 120 and wireless communication module 140, so that system on chip 120 is entered by sleep state
The working condition.In one embodiment of the invention, wireless communication module 140 is, for example, LTE module.
It should be noted that wireless communication module 140 is in the standby mode of low-power consumption under original state.Also, first
Under beginning state, wireless communication module 140 is set to keep sleep simultaneously timing and network communication.
It is carried out since the full-view image processing system of vehicle in the related technology generallys use external panorama processing module
Acquisition and splicing of full-view image etc., thus, it is equivalent to and increases an electronic control unit more, not only increase the control of vehicle
Complexity and cost processed, while being also unfavorable for the discovery direction of automotive electronics now, it may be assumed that move towards integrated central processing unit.
In addition, the full-view image processing system of vehicle in the related technology is at off-mode after flame-out, receive
Just starting to be switched on after ACC/WAKE signal, starting is slower, or high to operating system dependence, such as: RTOS will start fastly,
But the systems such as android will start slowly.External panorama processing module needs to wait for multimedia system initialization after the completion
Full-view image can be shown, so that response speed is relatively slow.
The multimedia entertainment system of the vehicle of the embodiment of the present invention due to not shutting down, but is in standby, power consumption
It is low and to be switched to working condition quick, such as can be accomplished below in 6mA, it, can be in addition, not harsh to operating system call
Operating mode will be quickly switched into, have after receiving trigger signal by carrying the operating systems such as RTOS, Linux, android
Good platform transplantation.In addition, the multimedia entertainment system of the vehicle is established under the framework of uniform hardware system, save outer
The panorama processing module set meets the integrated trend of automotive electronics, and saves cost, saves arrangement space.
Further, embodiment of the invention discloses a kind of vehicles, comprising: according to the vehicle in any of the above-described a embodiment
Multimedia entertainment system.The multimedia entertainment system of the vehicle does not shut down after vehicle stall, but is in standby shape
State, it is low in energy consumption and to be switched to working condition quick, such as can be accomplished below in 6mA, in addition, not severe to operating system call
It carves, the operating systems such as RTOS, Linux, android can be carried, after receiving trigger signal, Working mould will be quickly switched into
Formula has good platform transplantation.In addition, the multimedia entertainment system of the vehicle establishes the framework in uniform hardware system
Under, the panorama processing module of omitting external meets the integrated trend of automotive electronics, and saves cost, saves arrangement space.
In addition, other compositions of vehicle according to an embodiment of the present invention and effect are for those of ordinary skill in the art
For be all it is known, in order to reduce redundancy, be not repeated herein.
Fig. 3 is the flow chart of the control method of the multimedia entertainment system of vehicle according to an embodiment of the invention.Its
In, the multimedia entertainment system of the vehicle in the control method of the multimedia entertainment system of vehicle is to be implemented according to any of the above-described
