The signal strength of infrared signal is determined, for example can be believed according to the maximum of the received infrared signal of all infrared transceivers
The variation tendency of the signal strength of morning and evening and the received infrared signal of all infrared transceivers at the time of number intensity corresponds to
To determine.It is exemplary, referring to fig. 2, when first maximum signal of the received infrared signal of the first infrared transceiver 121
When corresponding earlier than first maximum signal of the received infrared signal of the second infrared transceiver 122 at the time of corresponding
It carves, and the time interval of two maximum signals of the received infrared signal of the first infrared transceiver 121 is red greater than second
When the time interval of two maximum signals of the received infrared signal of outer line transceiver 122, MCU can determine that shelter is
It is first moved to from the first infrared transceiver 121 at second infrared transceiver 122, then from the second infrared transceiver 122
Place is moved at the first infrared transceiver 121, thus MCU can determine shelter target trajectory be straight line move to right+

It is a corresponding Function Identification, the corresponding default corresponding relationship of different function mark is different.MCU can be worked as based on host computer of vedio device on vehicle
The Function Identification of the function of preceding realization determines corresponding default corresponding relationship.
Step 650, instruction device issue indication signal, which is used to indicate MCU and inquires target control instruction.
Exemplary, each infrared transceiver can be located on the inside of decorative panel for automobile.Multiple open has can be set in decorative panel for automobile
Hole, multiple apertures and multiple infrared transceivers correspond.Each aperture is provided with infra-red material.Infrared transceiver hair
The infrared ray penetrated can pass through aperture.Region of the decorative panel for automobile in addition to multiple apertures is provided with instruction device, the instruction device
It is electrically connected with MCU.After step 640, instruction device can be sent out indication signal, to prompt user's host computer of vedio device on vehicle
The target trajectory of shelter is recognized.
On the one hand, indication signal can be optical signal.Correspondingly, the process that instruction device issues indication signal can wrap
It includes：First controller control LED when MCU inquires target control instruction issues optical signal.
On the other hand, indication signal can be voice signal.Correspondingly, the process that instruction device issues indication signal can be with
Including：Second controller control buzzer when MCU inquires target control instruction makes a sound signal.
In addition, decorative panel for automobile can also be not provided with aperture in order to improve the transmitance of infrared ray, but all by thoroughly infrared
Material is made.
Step 660, MCU instruct control host computer of vedio device on vehicle according to target control.
After MCU has determined target control instruction, host computer of vedio device on vehicle can be controlled based on target control instruction.
For example, when target control instruction is plays next song, then MCU, which can then control host computer of vedio device on vehicle, is switched to next song
Song plays out.
