Description
Technical field
The utility model relates to automobile auxiliary safety device, relates in particular to a kind of system of carrying out alarm prompt and driving control in the time that safety strap is not worn.
Background technology
In running car, wear safety belt can significantly alleviate the injury that traffic accident causes driver and crew.Therefore the middle wear safety belt that travels is the important measures that ensure driver and crew's personal safety, has also carried out clearly regulation in traffic method.But people still usually forget wear safety belt in driving, or do not want to take the trouble and do not use of seat belts, bringing major hidden danger to traffic safety.Existing seatbelt wearing alarm set conventionally only carries out sound prompting and does not carry out vehicle control, although or carried out vehicle control, because control setup more complicated Occupation coefficient is not high.
Within open day, be that the patent documentation that on 03 25th, 2009, publication number are CN201211877Y discloses such technical scheme, a kind of safety belt warning device, comprise the voice prompting device arranging on seat, voice prompting device is connected with voice switch, seat switch, seat switch is open contact switch, starts voice prompting device and buckle well safety strap prompting in the time that people is sitting on seat.The weak point of this technical scheme is only to have carried out voice message, does not detain the further measure of control of safety strap, and to need that voice prompting device is set separately succinct not at each seat.
Summary of the invention
The utility model main purpose is to provide a kind of seatbelt wearing system for prompting, and its perfect in shape and function is rational in infrastructure, only has safety strap to meet to wear automobile while requirement normally to travel.
The utility model is mainly solved by following technical proposals for prior art problem, a kind of seatbelt wearing system for prompting, comprise the seat belt apparatus of automobile, safety strap ECU, Engine ECU and safety belt lock catch sensor, and LOAD CELLS, pulling force sensor and alarm unit, safety strap ECU is connecting engine ECU respectively, safety belt lock catch sensor, LOAD CELLS, pulling force sensor and alarm unit, LOAD CELLS is arranged under the seat cushion of seat, pulling force sensor is pasting safety strap surface two pulling force transmission ends and safety strap is being fixed, and the stressed axis of pulling force sensor is overlapped with safety strap longitudinal centerline.This technical scheme, whether the snap close sensor that uses of seat belts detects safety belt buckle and inserts in padlock, adopt LOAD CELLS to detect on seat whether have occupant, whether adopt pulling force sensor to detect safety strap is correctly worn, in the time correctly wearing, safety strap and body fit can produce the pulling force longitudinal along safety strap (tension force) and make pulling force sensor generation output signal, thus getting rid of false safe wearing zoning.Safety belt lock catch sensor obtains padlock signal, and passes to safety strap ECU, and safety strap ECU judges whether the safety strap on seat is worn, if when thering is no passenger such as assistant driver seat, does not just wear safety strap; If there is passenger, necessary wear safety belt, whether detect seat belt has and does not correctly wear phenomenon simultaneously, if when seat belt signal has a place not meet the demands, information is passed to Engine ECU, control the delivery quality of fuel-feed system, make delivery quality keep the delivery quality of idling mode, thereby vehicle cannot be accelerated; If safety strap signal all meets the demands, cancel the control to this delivery quality, vehicle can normally travel.Do not wear occurring wearing or when incorrect wear safety belt, alarm unit carries out alarm prompt simultaneously.
As preferably, pulling force sensor is that range is the 0 miniature spring sensor to double centner.For easy to install and use, the pulling force sensor that State selective measurements scope is suitable, size is again little, such as having adopted foil gage, JLBS-v type pulling force sensor is attached on alloyed steel elastic body, measurement range can be less than 10 millimeters at 0 to 10 kilogram, long 25 mm wide 30 millimeters thick, installs and uses all very convenient.
As preferably, pulling force sensor is fixed on safety strap surface in the mode of making.For not affecting structure and the performance of safety strap, adopt the mode of making that pulling force sensor is fixed on to safety strap surface.In the time making, the stressed axis of pulling force sensor is overlapped with safety strap longitudinal centerline to can correctly detect harness tension, distance between two pulling force transmission end attachment points of pulling force sensor is slightly less than the belt length between attachment point, i.e. also under tension of pulling force sensor when safety strap under tension.
As preferably, alarm unit comprises the safety strap indicator lamp and the buzzer phone that are arranged on gauge panel, and safety strap indicator lamp and buzzer phone be safety harness ECU respectively.
As preferably, between safety strap ECU and Engine ECU, adopt CAN bus mode to be connected.Utilize vehicle-mounted CAN bus to communicate easy to connect, reliable.
The beneficial effect that the utility model brings is, in reminding driver and crew's wear safety belt, can take to control the coercive measure of throttle, only wear after requirement satisfied, automobile could normally travel, and there is safety strap and correctly wear detection, effectively getting rid of false seatbelt wearing phenomenon, system architecture is simple, perfect in shape and function, easy to use.
Brief description of the drawings
Fig. 1 is a kind of functional block diagram of the present utility model;
Fig. 2 is a kind of scheme of installation of pulling force sensor.
In figure: the 1st, safety belt lock catch sensor, the 2nd, LOAD CELLS, the 3rd, pulling force sensor, the 4th, alarm unit, the 5th, safety strap ECU, the 6th, Engine ECU, the 7th, CAN bus, the 8th, safety strap, the 9th, make cotton rope.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1 and Figure 2, the utility model is a kind of seatbelt wearing system for prompting.Safety strap ECU 5 connecting engine ECU 6, safety belt lock catch sensor 1, LOAD CELLS 2, pulling force sensor 3 and alarm unit 4 respectively.
Wherein, LOAD CELLS 2 adopt S type duplex cellular type (partially anti-, lateral resistant ability strong), measurement range at 2Kg the LOAD CELLS to 100Kg, be arranged between the seat cushion and seat support skeleton of seat; Pulling force sensor 3 adopts JLBS-v type pulling force sensor to fix in the mode of making, in the time making, the stressed axis of pulling force sensor 3 is overlapped with safety strap 8 longitudinal centerlines, distance S between the attachment point of two pulling force transmission ends of pulling force sensor (side a and b) is slightly less than the belt length J between attachment point, make the rear cotton rope 9 of making as seen, also under tension of pulling force sensor 3 in the time of safety strap 8 under tension; Safety strap ECU5 communicates to connect by CAN bus 7 and Engine ECU 6; Alarm unit 4 comprises that safety strap indicator lamp is also connected with safety strap ECU5 respectively with buzzer phone, and safety strap indicator lamp and buzzer phone are arranged on gauge panel.
When after automobile starting, safety strap ECU 5 detects connected each safety belt lock catch sensor 1(and in car, is located at major and minor driving on seat), in the time detecting that safety belt buckle does not insert padlock in addition, detect on this seat whether have people by corresponding LOAD CELLS 2, if someone takes, carry out safety strap indicator lamp warn and buzzer phone warn, and notify Engine ECU delivery quality to keep the delivery quality of idling mode, vehicle can not be raised speed; All insert after padlock at the safety belt buckle that should insert, safety strap ECU 5 detects corresponding pulling force sensor again, illustrates that safety strap correctly wears after belt force reaches setting value, and vehicle can normally travel, and removes alarm prompt; Otherwise continue to control oil mass, until safety strap is correctly worn.
