The method of operation of claim 7, wherein: if the stream media rearview mirror judges that the vehicle steering lamp information intervenes, acquiring the running speed and the course angle of the rear vehicle, acquiring the running speed and the course angle of the vehicle from a vehicle VCU through a CAN bus, comprehensively analyzing and calculating the predicted collision time TTC based on the running speed and the course angle of the rear vehicle and the vehicle, judging whether the predicted collision time TTC is smaller than a preset TTC threshold value or not, and judging whether the lane change is possible or not; and if the stream media rearview mirror judges that the information intervention of the vehicle steering lamp does not exist, the steering auxiliary suggestion display module (3) displays 'forbid lane changing', and a driver keeps the vehicle going straight.
9. The method of operation of claim 8, wherein: if lane changing can be achieved through the judgment, the tire pressure detection module acquires a current tire pressure value, whether the current maximum tire pressure difference is smaller than a maximum tire pressure difference limit value under the current running speed of the vehicle or not is judged, if the current maximum tire pressure difference of the vehicle is smaller than the maximum tire pressure difference limit value under the current running speed of the vehicle or not, the steering auxiliary suggestion display module (3) displays that lane changing is allowed for a driver to finish lane changing, otherwise, the steering auxiliary suggestion display module (3) displays that lane changing is forbidden, and the driver keeps the vehicle to run straight.
10. The method of operation of claim 9, wherein: the tire pressure detection module converts a corresponding maximum tire pressure difference limit value according to the running speed of the current vehicle;
the tire pressure detection module is internally provided with a lowest tire pressure limit value and a highest tire pressure limit value, and when the tire pressure detection module detects that the tire pressure is lower than the lowest tire pressure limit value or higher than the highest tire pressure limit value, the control module controls the tire pressure display module to highlight.
