Abstract

The invention discloses a vehicle alarm system which comprises a DSP control chip, a detection unit and an alarm unit. The detection unit judges whether a moving target exists in a preset scope at back of a vehicle or not according to a detection command of the DSP control chip, the moving target is detected when the detection unit judges that the moving target exists in the preset scope, and a first detection signal obtained by detection is supplied to the DSP control chip through the detection unit; the DSP control chip judges whether a door opening early alarm is required or not according to the first detection signal provided by the detection unit, and a door opening alarming signal is supplied to the alarm unit through the DSP control chip if the DSP control chip judges that the door opening early alarm is required; the alarm unit gives an alarming prompt to a user in the vehicle according to the door opening alarming signal provided by the DSP control chip. According to the vehicle alarm system, vehicle accidents caused by vehicle door opening ate avoided, and the use safety performance of the vehicle is improved. In addition, a passenger is not required to watch the state at back of the vehicle before getting off the vehicle, and better riding comforts are provided for the passenger.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle alarm system.
