Description
Technical field
The present invention relates to automobile, particularly relate to a kind of automobile with intelligent key system and tire pressure monitoring system.
Background technology
Automobile is in the process of running at high speed, and tire fault is that all chaufeurs are worried and the most difficult prevention the most, is also the major reason that sudden traffic accident occurs.How preventing from blowing out becomes an important topic of safe driving.And the pressure of tire maintained the standard travels and Timeliness coverage tire flat is the key preventing from blowing out.Tire pressure is the important indicator affecting running car performance and safety performance.When tire pressure is too high, can reduce the area of contact on tire and ground, and the pressure that now tire bears improves relatively, the earth-grasping force of tire can be affected, and makes the friction force of tire weaken and cause braking quality to decline.In addition, when running car is at roughness pavement, such as through ditch or road surface of jolting, tire and wheel frame are easy to be out of shape because travelling impact that uneven road surface produces, there is no sufficient space absorbing vibration in tire, the stability travelled except impact and travelling comfort, even cause outside blowing out, also can cause and the impact of suspension is put more effort, also can bring harm thus.Meanwhile, the hidden danger of blowing out when high temperature also can increase accordingly.When tire pressure is too low or leak gas, the friction force on tire and ground is multiplied, and tire not only can be caused to produce the damage of abnormal wearing and tearing or inside tires mechanism, increase oil consumption simultaneously, and, run at high speed when low tire pressure, because tire sidewall is the weak part of tire, when tire pressure is too low, can constantly be squeezed and stretch, easily cause fatigue failure, more may cause and blow out, except badly damaged tire, more very likely cause unexpected traffic accident.Have data to show, the ratio of the traffic accident caused by blowing out shared by pernicious traffic accident is very high, and all meetings cause tire pressure deficiency in the factor of blowing out to work as first cause.
Therefore, carrying out monitoring in real time to tire pressure is the important means ensureing tire safety.In order to provide vehicle safety, tire pressure monitoring system (TPMS, Tire Pressure Monitoring System) technology has been applied on automobile gradually.First tire pressure monitoring system needs exception tire pressure being detected in time; usually a kind of device for monitoring tyre pressure can be used; this device for monitoring tyre pressure utilizes the pressure sensor being arranged on wheel tyre cavity directly to measure air pressure in tire; and; utilize wireless launcher pressure information to be sent to system central receiver module from inside tires, then each tire pressure information is shown.When tire pressure is too low or leak gas, system can automatic alarm.The actual wink that can measure each inside tires due to this device at any time presses, and is easy to determine fault tire, therefore obtains car production manufacturer and use more widely.Because each pressure sensor of taking turns tyre cavity needs to communicate with the control system of automobile, therefore usually need on each wheel cover, to arrange a low-frequency antenna respectively, that is one 4 automobile of taking turns, need installation 4 low-frequency antennas.
On the other hand, the development of technology has promoted the renewal of product, original mechanical key develops into command and control system, along with RF identification (Radio Frequency Identification, RFID) the extensive utilization of technology and the demand of automotive market, command and control system will be substituted by keyless access system again.Keyless access system, namely intelligent key system, it has continued to use traditional vehicle circuitry protection, and realize dual radio frequency system, double anti-theft is protected, for car owner provides convenient and safety to greatest extent.At present, entering with start up system (PEPS, Passive Entry & Push Start) without key is a kind of typical intelligent key system.Whether have Intelligent key in the service area of car to detect, typical intelligent key system needs at least to arrange 3 low-frequency antennas in car load outside.
