Abstract
The utility model provides a seat belt pre-tensioning control device which belongs to the technical field of seat belts of vehicles and solves the problem that the tension of the conventional seat belt of the vehicle cannot be automatically adjusted during fast turning and sideslip. The seat belt pre-tensioning control device comprises a control module, a vehicle yaw velocity sensor and an X/Y-direction acceleration sensor, wherein the yaw velocity sensor and the X/Y-direction acceleration sensor are respectively used for detecting the actual yaw velocity and the actual barycenter sideslip angle of a vehicle; and the control module is used for analyzing the detected actual yaw velocity and actual barycenter sideslip angle of the vehicle and then outputting a corresponding control signal to a seat belt device so as to adjust the tension of the seat belt. The utility model has the advantage of detecting the yaw movement and the side movement of the vehicle during driving so as to prevent the head of a passenger from colliding with a side B column or prevent the body of the passenger from leaving a seat by pre-tensioning the seat belt in case of too fast turning.
Description
Technical field
The utility model belongs to the car belt technical field, relates to a kind of safety strap pretension control setup.
Background technology
Vehicle is when turning or break away, because centrifugal action, passenger's body can tilt laterally.If turn inside diameter or slipspeed are too fast, the angle of inclination of passenger's body can become greatly, and strength also can strengthen thereupon, exists head of passenger bump side B post or health to leave the danger of seat.
Though occurred the safety strap of scalable elasticity at present, mainly still design-calculated can't be realized the automatically regulating of automobile in carrying out flipper turn and sideslip process to this safety strap for the people who looks after different builds.
Summary of the invention
The purpose of this utility model is at the existing the problems referred to above of existing car belt, and proposed a kind of can be according to the running car situation, tighten seat belt is to prevent the occupant and disseat or the safety strap pretension control setup of head impact car interior trimming parts in advance.
The purpose of this utility model can realize by following technical proposal: a kind of safety strap pretension control setup, it is characterized in that, this control setup comprises control module, automobile yaw-rate sensor and X, Y is to acceleration pick-up, described yaw-rate sensor and X, Y is respectively applied for to acceleration pick-up and detects actual yaw velocity of automobile and actual side slip angle, above-mentioned control module is analyzed back output control signal corresponding to seat belt apparatus to actual yaw velocity of detected automobile and actual side slip angle, regulates the elasticity of safety strap.
Yaw-rate sensor is used for monitor vehicle weaving and sideway movement, X, Y then are to be used to judge Vehicular turn degree and barycenter deviation angle to acceleration pick-up, control module is according to detected these real data, analyze comparison in conjunction with the standard value that preestablishes storage, send control signal corresponding and give seat belt apparatus, whether need to select the pretension safety strap.
In above-mentioned a kind of safety strap pretension control setup, described safety strap pretension control setup also includes car speed sensor, and this car speed sensor is connected with control module, is used to detect automobile speed.Control module is when analyzing comparison, and the reference speed signal makes that judgement is more accurate simultaneously.
In above-mentioned a kind of safety strap pretension control setup, described seat belt apparatus is an active belt, has the motor of scalable safety belt tightness.Active belt has the function of scalable safety belt tightness, the controlled module controls of motor, and the motor forward or reverse is used for respectively controlling the tension of safety strap or loosening.
Compared with prior art, safety band pretension control setup can monitor vehicle weaving and sideway movement in vehicle traveling process, when turn too fast and break away might cause that the occupant disseats or the situation of head impact side B post under, the pretension safety strap prevents that head of passenger bump side B post or health from leaving seat.
Description of drawings
Fig. 1 is the functional-block diagram of safety band pretension control setup.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, safety band pretension control setup comprises control module and is connected automobile yaw-rate sensor on the control module, X, Y to acceleration pick-up and car speed sensor, yaw-rate sensor is used to detect the actual yaw velocity of automobile, reacts the weaving and the sideway movement degree of vehicle with this.X, Y then are used to detect the actual side slip angle of automobile to acceleration pick-up, react Vehicular turn degree and barycenter deviation angle with this.
After control module receives and detects the actual yaw velocity of automobile and actual side slip angle that obtains, analyze comparison with the standard value that preestablishes storage, after finding that actual value surpasses established standards, representing then that the occupant can and break away because of the turning of vehicle too fastly disseats or strikes on the car interior trimming parts, at this moment, control module is sent the motor that the pretension control signal is given seat belt apparatus, and the pretension safety strap prevents that head of passenger bump side B post or health from leaving seat.
After the band vehicle is finished turning or sideslip reduction of speed, this moment, automobile yaw-rate sensor and X, Y all returned normal condition to detected each actual value of acceleration pick-up, and far below setting value, send by control module this moment and loosen the motor that control signal is given seat belt apparatus, the safety strap of straining before is relaxed to initial condition.
Because vehicle is when turning, its speed of a motor vehicle is very big to the influence of vehicle centnifugal force, therefore also will analyze in conjunction with the vehicle speed signal of vehicle when carrying out analysis and judgement.
Belt pull device in the present embodiment is a prior art, is not just giving unnecessary details at this, and detailed structure can disclosed with reference to Chinese patent " retraction system of safety belt ", and its publication number is: 1297829.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (3)
