The invention relates to an automobile collision protection device, a monitoring protection method and an automobile equipped with a collision protection device, the device comprises an ultrasonic
ranging and speed measuring module, control display module, voice alarm module, A lase
fog lamp adjusting module and a buff
airbag ejecting module, The ultrasonic
ranging and speed measuring module usestwo ultrasonic groups before and after to calculate the relative distance, speed and acceleration information between the vehicle and the front and rear vehicles through the ultrasonic
ranging methodof sending
square wave and receiving
square wave and combining the sound speed compensation of the temperature compensation module. The ultrasonic ranging and speed measuring module is used to calculate the relative distance, speed and acceleration information between the vehicle and the front and rear vehicles. The voice alarm module is used for voice real-time
broadcasting; The
laser fog lamp adjustment module is used to warn the rear vehicle of the occurrence of dangerous conditions; The
cushioning airbag ejection module releases the
airbag from the vehicle body when the
system calculates and judges that the current driving condition of the vehicle is in a state where a collision can occur at any time, and rapidly inflates the airbag, thereby playing a
cushioning role.
