Fig. 2 is the connection diagram of seat headrest control device application scenarios of the present utility model.
Detailed description of the invention
For technical matters, technical scheme and advantage that embodiment of the present utility model will be solved are clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments, but the utility model is not limited to these embodiment.
As shown in Figure 1, be a kind of seat headrest control device of the present utility model, for the first vehicle, comprising:
Be used for the radar detector 11 of the motoring condition of second vehicle of monitoring described the first rear view of vehicle;
For generate the electronic control unit 12 of control command according to the motoring condition of described the second vehicle, be connected with radar detector 11 electric signal;
For the chair headrest controller 13 of chair headrest being controlled according to described control command, be connected with described electronic control unit 12 electric signal.
Described motoring condition comprises: the current following distance between described the second vehicle and described the first vehicle and the current relative velocity of described the second vehicle and described the first vehicle;
Described electronic control unit 12 comprises:
Calculating unit, calculates the current safety stopping distance that described current relative velocity is corresponding;
The first control unit, in the time that described current following distance is less than described current safety stopping distance, generates the control command of chair headrest reach; Described the first control unit is connected with described calculating unit electric signal;
The second control unit, for being greater than described current safety stopping distance when described current following distance, and the upper moment following distance between described the second vehicle and described the first vehicle was less than upper moment between described the second vehicle and described the first vehicle when safe stopping distance, generated the control command of moving after chair headrest; Described the second control unit is connected with described the first control unit and described calculating unit respectively.
The 3rd control unit, in the time that vehicle starts to travel, if described chair headrest is shift state, generates the control command that chair headrest resets.
