Description
The invention belongs to vehicle security drive technical fields, monitor speed control method more particularly, to a kind of car belt.
Safety belt and air bag are configured as the auxiliary of automotive SBC, are increasingly valued by people.Although
Air bag is constantly generalized intelligence increasingly, but safety belt is still to protect interior driver and passenger's safety so far the most
Effective device, and it is widely used in automotive field, it is played an important role in terms of guaranteeing occupant safety.When automobile occurs
When head-on crash, side collision and rolling, safety belt respectively reaches 57%, 44% and 80% to the reduction degree of accident death rate, not
A possibility that being ejected outside vehicle in driver and passenger's collision accident of fastening the safety belt is 10 times higher than the driver and passenger to use of seat belts." road
Road traffic safety law " clearly stipulate that have to fasten seat belts in driving, but effect and pay no attention in actual use
Think, the traffic mortality in China is significantly higher than developed country, but belt usage rate is significantly lower than developed country, reason master
If the indifferent and excessive of awareness of safety takes notice of that discomfort when wear safety belt is felt, therefore safety belt for vehicle is reminded and pressure
It is had practical significance using the popularization of system.
There are also the safety belt for vehicle with prompting function, such as notification number at present are as follows: the middle promulgated by the State Council of CN102407825A
A kind of voice safety belt that bright patent provides, installs pressure sensor, in the safety buckle of car belt in automobile cushion
Installation switch, sensor connects voice prompting: " Buckle Up ", pressure when buckling well safety belt when meeting the pressure condition of setting
The switch of force snesor disconnects.The voice safety belt only emphasizes the importance of safety belt by voice prompting, and car is reminded to multiply
Member fasten seat belts, effect is very limited in actual use, scorch even joyride when, still can safety belt buckling free and just
Often driving, there are driving safety hidden danger.
The present invention has primarily directed to safety belt using effect present in the existing safety belt for vehicle with prompting function
Limit, belt usage rate is low, however it remains the problem of driving safety hidden danger, it is preferable to provide a kind of safety belt using effect, safety
Band utilization rate is low, and the higher car belt of travel safety monitors speed control method.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals: a kind of car belt prison
Speed control method is surveyed, further includes speech prompting device and setting in belt buckle including automobile ECU and vehicle speed sensor
In sensing device, vehicle speed sensor, speech prompting device and sensing device are electrically connected with automobile ECU, cross in garage
Cheng Zhong, after reeler rotation or the lock tongue insertion buckle of safety belt, sensing device works and sends safety signal to automobile
ECU, automobile normal running, when automobile ECU does not receive the safety signal of sensing device transmission, vehicle speed sensor works as transmission
Preceding speed numerical value to automobile ECU, is made following comparison and determined by automobile ECU by speed numerical value:
A) when speed is less than 40km/h, automobile normal running;
B) when speed is located at 40~60km/h, automobile ECU sends a command to speech prompting device, and speech prompting device reception refers to
After order, alarm sound is issued, driver and passenger is reminded to fasten seat belts;
C) when speed is located at 60~80km/h, automobile ECU controls engine speed, and speed ceiling restriction is being not more than
100km/h, and automobile ECU sends a command to speech prompting device, after speech prompting device receives instruction, issues human voice
It informs that driver and passenger limit speed, and driver and passenger is reminded to fasten seat belts;
D) when speed is located at 80~100km/h, automobile ECU controls engine speed, and speed is gradually reduced to 20km/h, and
Speech prompting device is sent a command to, human voice is issued and informs that driver and passenger reduce speed.
E) in any one step of above a, b, c, d, if automobile ECU receives the safety signal of sensing device transmission, cancel
Subsequent speed numerical value determination step, automobile normal running.
Sensing device is connect with automobile ECU, sense after reeler rotation or the lock tongue insertion buckle of safety belt, in buckle
It answers device that can learn that safety belt has been fastened, at this moment will send safety signal to automobile ECU, automobile ECU can be according to peace
Full signal judges whether safety belt has been fastened, if driver and passenger wear safety belt, automobile normal running, if driver and passenger are not
Wear safety belt, automobile ECU determine the speed numerical value issued to vehicle speed sensor, when speed falls into a, b, c, d tetra-
In the velocity interval of step, by according to corresponding step, automobile ECU sends control command adapted thereto to each device, to the full extent
Remind driver and passenger's wear safety belt.Warning indicator light or buzzer can be used in alarm set, reminds driver and passenger's safe wearing
Band.It is well known that speed is faster, it is more easy to happen traffic accident, safety belt monitoring speed control method can control always speed
System can improve the utilization rate of safety belt within 100km/h to the full extent, protect driver and passenger's security of the lives and property, with
Pressure uses of seat belts, and otherwise automobile can not start and compare, it appears and it is humanized, it is easier to be received by numerous car owners.
Preferably, the vehicle speed sensor, speech prompting device and sensing device are powered by automobile storage battery.Even
Connect simple and convenient, high reliablity.
Preferably, the sensing device is trigger switch or inductive pick-up.After safety belt is fastened, trigger switch or
Inductive pick-up works and will send safety signal to automobile ECU.
Preferably, it further includes the warning lamp connecting with automobile ECU.Increase warning lamp, further improves safety belt
Use, to the full extent protect driver and passenger's security of the lives and property.Warning lamp is used cooperatively with speech prompting device, and effect is more
Good, such as first 10 seconds are alarming lamp prompt, prompt within latter 10 seconds for alarm or human voice prompts.
Therefore, the beneficial effects of the present invention are: safety belt monitoring speed control method can control always speed
Within 100km/h, the utilization rate of safety belt can be improved to the full extent, driver and passenger's security of the lives and property is protected, with pressure
It uses of seat belts, otherwise can not drive a vehicle and compare, it appears it is humanized, it is easier to be received by numerous car owners.
