The rearward display screen is relatively high, and its display content can be observed by more rearward vehicles.

[0044] In this embodiment, if Figure 2As shown, the interaction method between the driving vehicle and the following vehicle includes:

[0045] S210: The in-vehicle voice collection system 110 collects the driver's first interactive voice, where the first interactive voice corresponds to a first bad driving behavior of the following vehicle.

[0046] The first bad driving behavior includes turning on the high beam when the visibility is relatively good, causing a dazzling effect on the driver of the vehicle, etc. The first interactive voice corresponding to turning on the high beam when the visibility is relatively good may be "prompt the vehicle behind to turn off the high beam".

[0047] S220: The in-vehicle voice collection system 110 sends the first interactive voice to the voice conversion system 120, and the voice conversion system 120 converts the first interactive voice into a first text message.

[0048] S230 : the speech conversion system 120 sends the first text information to the head-up display device 130 .

[0049] S240: The head-up display device 130 displays the first text information, and transmits the first text information to the rear display area 140 of the vehicle.

[0050] On the basis of the above, the interaction method between the driving vehicle and the following vehicle also includes:

[0051] S250: Determine whether the in-vehicle voice collection system 110 has collected a second interactive voice with the same meaning as the first interactive voice. If so, execute S260. Otherwise, return to S210.

[0052] Among them, the first interactive voice is earlier than the second interactive voice.

[0053] It should be noted that in the actual driving process, after a period of time after the first text message is displayed in the rear display area after the own vehicle passes, if the rear vehicle still does not change its bad driving habits and the driver of the own vehicle is still affected by it, the driver of the own vehicle will remind it again through voice. At this time, the in-vehicle voice collection system 110 will collect a second interactive voice with the same meaning as the first interactive voice (for example, "continue to remind the vehicle behind to turn off the high beam"), and the decibel number of the second interactive voice at this time may be higher than that of the first interactive voice.

[0054] As an embodiment, after S250, S260 is directly executed: after the head-up display device 130 receives the second text information corresponding to the second interactive voice sent by the voice conversion system, the second text information is bolded and transmitted to the rear display area of ​​the vehicle.

[0055] On the basis of the above, preferably, Figure 1As shown, the interactive system between the driving vehicle and the following vehicle further includes a driver monitoring system 150 , and the driver monitoring system 150 is signal-connected to the head-up display device 130 .
