The invention relates to a vehicle
dynamic display device and a displaying method thereof. The vehicle
dynamic display device comprises an MEMS microaccelerometer, a vehicle state
discriminator, a driver, a
LED display or an EL emitting
diode. An
accelerometer is adopted for detecting state; an automatic decision can be performed on states of collision,
emergency brake, urgency
speed reduction, general
speed reduction and acceleration through the vehicle state
discriminator; real-time display can be respectively performed according to the urgent degree ordering in various colors,
graphics, characters or the combination thereof; hand operation is replaced by
automatic control, and the two signals of Preparation-Break replace break signals, so that the difficulty of
Emergency Brake Precaution is solved. Once a vehicle is in danger, all vehicles thereafter can synchronously put on the brakes as well as the front vehicle, and an early warning time of 0.8 second to 1 second can be gained, thereby effectively avoiding the phenomena of driving too close to the car in front and serially driving too close to the car in front. The comprehensive early warning mechanism overcomes a plurality of defects in the traditional
signal lamp and creates the beginning of mutual communication among vehicles, knowing one and others and
safe driving. The invention has the advantages of low cost, high
cost performance and simple installation, and is suitable for high-level installation at the
tail parts of various vehicles and the installation of rear boxes of motorcycles and mopeds.
