Specifically, speed and body-acceleration sensor 20 are that electronic control unit 70 provides traveling vehicle condition signals collecting, The internal pressure of Intelligent adjustment inflatable seat belt, to improve the active protective value of inflatable seat belt and provide early warning Function.For example, speed is divided into three ranks：One-level (speed：Below 50km/h, inflatable seat belt is pressed in human body On power be 3～5N)；Two grades (50～100km/h of speed, inflatable seat belt is pressed in the power on human body for 5～8N)； Three-level (100～130km/h of speed, inflatable seat belt is pressed in the power on human body for 8～10N), concrete rank is arranged can To do different adjustment according to region crowd and its laws and regulations requirement difference.
Positive bump sensor 10 is to provide collision alarm collection for electronic control unit 70, to provide inflatable seat belt needs The Millisecond function signal of rapid deployment, reaches the safety of effective protection collision rift driver and crew.
Bracelet inflated condition number device for picking 60 is that the pressure signal that controlling switch 200 is obtained is sent to into electronic control unit 70, it is that aerating device 40 passes through the basis for estimation that gas flow control device 50 carries gas supply regulation.
Alternatively, aerating device 40 is compression pump.
Bracelet aeration control device 30 according to embodiments of the present invention, by arranging lock assembly 400, can be by dead bolt 300 It is locked in band catching groove 120, so as to realize the locking of inflatable seat belt, also, controlling switch 200 is set by progressive one, And using the linkage of dead bolt 300 and controlling switch 200, the detection of pressure after Aerated safety locking is realized, consequently facilitating Air demand is adjusted according to the pressure after Aerated safety locking, active constraint is realized, security and comfortableness is improved.
Bracelet ventilating control system according to embodiments of the present invention, inflates by using bracelet according to the above embodiment of the present invention Control device 30, can adjust air demand according to the pressure after Aerated safety locking, realize active constraint, improve safety Property and comfortableness.
Automobile 1 according to embodiments of the present invention, by using bracelet ventilating control system according to the above embodiment of the present invention, tool Have the advantages that security and comfortableness are high.
Below with reference to the accompanying drawings bracelet ventilating control system according to the specific embodiment of the invention is described.
As shown in figure 1, bracelet ventilating control system according to embodiments of the present invention includes positive bump sensor 10, speed and vehicle body Acceleration transducer 20, bracelet aeration control device 30, aerating device 40, the inflation of gas flow control device 50, bracelet Status number device for picking 60 and electronic control unit 70.
Further, as shown in figure 1, the bracelet ventilating control system also includes that bracelet aerating device starts selecting switch 80, Bracelet aerating device starts selecting switch 80 and communicates with electronic control unit 70.
It is that the startup of inflatable seat belt is selected after automobile 1 starts that bracelet aerating device starts selecting switch 80, for example, There can be three kinds of start-up modes to select：One-key start pattern, new person's pattern and close pattern.
Driver and crew can according to demand carry out model selection, if Jing is normally opened car personnel, memory function can be selected to carry out One-key start.It is gentle by bracelet inflated condition number device for picking 60 if new human pilot, can be started by new person's pattern Body volume control device 50 will inflate shoulder belt and waistband is automatically adjusted to the more comfortable state of human body with the power of the contact of human body (usually 3-5N).If driver and crew need not start inflatable seat belt, close pattern can be selected.
In some specific examples of the present invention, as shown in figure 1, the bracelet ventilating control system also includes controller local Network bus 91 (CAN), body electronics stability controller 92 (ESP), local weighted regression algorithm controller 93 (LWR), Digital information switch 94 and instrument signal display device 95.
