The current driving speed of the target vehicle, and judge whether the current driving speed is more than pre-set velocity
Threshold value；
Control module, for when the current driving speed is more than pre-set velocity threshold value, by the target
The current driving speed of vehicle is reduced to the pre-set velocity threshold value.
Preferably, described device also includes：
Determining module, for according to the pre-determined distance threshold value, it is determined that with the pre-determined distance threshold value positive
The pre-set velocity threshold value of pass.
Preferably, the determining module is specifically used for：
According to the pre-determined distance threshold value, it is determined that the pre-set velocity threshold directly proportional to the pre-determined distance threshold value
Value.
Preferably, the detection module is specifically used for：
Target vehicle and the distance value of front vehicles are detected by infrared technique or Radar Technology.
Preferably, described device also includes：
3rd judging unit, for judging whether the distance value of the detection is less than minimum predetermined distance threshold；
If so, the current driving speed of the target vehicle is down to zero.
Compared with prior art, the advantage of the invention is that：The present invention is by detecting target vehicle and front
The distance value of vehicle, and when the distance value of detection is less than pre-determined distance threshold value, judge the current driving
Whether speed is more than pre-set velocity threshold value, if the current driving speed is more than pre-set velocity threshold value, by institute
The current driving speed for stating target vehicle is reduced to the pre-set velocity threshold value., can be with by said process
Ensure that target vehicle is in a kind of safe speed state all the time, so as to reduce the probability of traffic accident generation.
