Description of drawings
Fig. 1 is the principle schematic of the utility model embodiment safety strap tightening system.
Fig. 2 is the electrical block diagram of the utility model embodiment safety strap tightening system.
The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein identical or similar label is represented identical or similar elements or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.
With reference to the principle schematic that Figure 1 shows that the utility model embodiment safety strap tightening system, Fig. 2 is the electrical block diagram of the utility model embodiment safety strap tightening system.
As shown in the figure, after automobile ignition switch 11 closures, storage battery 12 is electronic control unit 10 and radar controller 1 power supply, and the safety strap tightening system powers on and starts working.
Steering angle sensor 6 is fixed on the tubing string of bearing circle 7, can detect the steering angle of vehicle, and the steering angle signal is sent to electronic control unit 10.
Brake-pedal-travel sensor 4 is fixed on the support of brake pedal 5, detects braking distance when brake pedal 5 is operated, and the braking distance signal is sent to electronic control unit 10.
A plurality of radar sensors 3 are fixed on the front bumper 2, detect the distance of the place ahead obstacle and this car in real time, and the range signal of obstacle is sent to radar controller 1.Certainly, radar sensor 3 also can be arranged at other position of vehicle body, for example is arranged on the front and back of vehicle body simultaneously, can detect the distance of obstacle and this car at vehicle front and rear so simultaneously, and this also belongs in the protection domain of the present utility model.
First kind of situation, after bearing circle 7 rotated, steering angle sensor 6 provided the Vehicular turn angle signal to electronic control unit 10.The vehicle speed signal that electronic control unit 10 is gathered car speed sensor 16.When vehicle speed signal 〉=5Km/h, electronic control unit 10 compares signal and the predefined steering angle threshold value that steering angle sensor 6 provides.When surpassing predefined steering angle threshold value, expression turn inside diameter amplitude is bigger, this moment, electronic control unit 10 control metal-oxide-semiconductors 13 drove Webbing retractor 9 work, Webbing retractor 9 tighten seat belt 8,8 pairs of human bodies of safety strap play the constraint effect, human body wigwag motion when avoiding Vehicular turn.
Second kind of situation, when brake pedal 5 was operated, brake-pedal-travel sensor 4 provided the braking distance signal to electronic control unit 10.The vehicle speed signal that electronic control unit 10 is gathered car speed sensor 16.When vehicle speed signal 〉=5Km/h, electronic control unit 10 compares braking distance signal and the predefined braking threshold value that brake-pedal-travel sensor 4 provides, when surpassing predefined braking threshold value, the expression vehicle is carrying out emergency braking, this moment, electronic control unit 10 control metal-oxide-semiconductors 13 drove Webbing retractor 9 work, Webbing retractor 9 tighten seat belt 8,8 pairs of human bodies of safety strap play the constraint effect, avoid human body because of the emergency braking preshoot.In the present embodiment, described braking distance comprises the drafts of described brake pedal 5 and/or depresses speed, corresponding with it, described braking distance threshold value comprises the drafts threshold value and/or depresses threshold speed, when any braking distance wherein during greater than the braking distance threshold value of correspondence, electronic control unit 10 all can drive Webbing retractor 9 work.
