A kind of automotive tire pressure checking system
Technical field
The utility model relates to automotive tire pressure checking system technical field.
Background technology
The automotive tire pressure checking system of selling on the current market (is called for short: TPMS), be made up of man-machine interface, information reception and processing module, information detection and transmitter module three big modules, as shown in Figure 1.Information detection and transmitter module generally are installed in the tire, and man-machine interface and information receive and processing module constitutes the demonstration main frame usually.TPMS after installation, use before, require the user that some operational parameter value (as pressure and temperature alarming threshold values) directly is set, arrange as information (parameter) load module by man-machine interface.Have only these parameters of working as that its due effect of TPMS competence exertion is set correctly.
The value of these parameters is difference along with the difference of vehicle or tyre kind, and different automobile scenarios and different road conditions even with season also influential to these parameters.On the one hand, because the user lacks relevant expertise, car body self character and tire parameter are not understood, might be caused the incorrect of parameter setting; On the other hand, the user can not adjust the parameter setting accordingly along with the difference in automobile scenarios, road conditions even season, thereby make the monitoring accuracy rate of TPMS be affected, that is to say that in the market TPMS can not take seasonal variation, actual road conditions and automobile load into account motor tire is monitored accordingly.
Summary of the invention
The utility model purpose is to propose to make things convenient for the user, and can be according to the automotive tire pressure checking system of the split hair caccuracy of actual vehicle condition.
First kind of technical scheme of the present utility model is: system comprises man-machine interface, information receives and processing module, information detection and transmitter module, it is characterized in that also comprising the operating parameter setting module, described man-machine interface has the input of the vehicle condition information that comprises vehicle at least or selects module, described operating parameter setting module has the information table of the temperature and pressure threshold values that a vehicle condition information that contains vehicle at least is suitable for, described operating parameter setting module also comprises the module of reading in the vehicle condition information that comprises vehicle at least from man-machine interface, search aforesaid information table obtaining the module of corresponding temperature and pressure threshold values according to the information of reading in, the temperature and pressure threshold values information information that is sent to that described operating parameter setting module also has the correspondence that will find receives the module with processing module.
The core of operating parameter setting module of the present utility model is one and contains relevant with information such as vehicle and the temperature that is suitable for, the information table (being called for short TPMS vehicle and tire parameter table) of pressure threshold value.The user only needs to carry out input or the selection of information such as vehicle by the MIM message input module of man-machine interface, the operating parameter setting module then can be moved automatically, search suitable temperature and pressure threshold values information, and this information information that is sent to received and processing module, receive and processing module is used for information.That is to say: the required parameter value (as pressure and temperature alarming threshold values) of this TPMS operation is not by directly input and setting of user, but obtains and set by indirect mode.The utlity model has and make things convenient for the user, reach accurately the function that pressure and the temperature alarming threshold values the most adaptive with using vehicle condition is provided to the TPMS system, to guarantee the safe in operation of vehicle.
Man-machine interface in the above technical scheme except be used for to show relevant information and report to the police with, input or the selection of the information such as type that also are used for buying car in installments.
The above comprise at least the vehicle condition information of vehicle also comprise with the adaptive tyre model of vehicle and season information.
The described vehicle condition information of vehicle that comprises at least also comprises traffic information or vehicle load information.
Can for input or the information of selecting except with vehicle, the tyre model adaptive with vehicle, corresponding season, the road conditions of travelling and vehicle load etc. actual information can also be arranged.
Second kind of technical scheme of the present utility model is: system comprises man-machine interface, information receives and processing module, information detection and transmitter module, it is characterized in that also comprising operating parameter setting module and In-vehicle networking receiver module, described In-vehicle networking receiver module has the load module that reception comprises the vehicle condition information of vehicle at least, described operating parameter setting module has the information table (TPMS vehicle and tire parameter table) of the temperature and pressure threshold values that a vehicle condition information that contains vehicle at least is suitable for, described operating parameter setting module also comprises the module of reading in the vehicle condition information that comprises vehicle at least from the In-vehicle networking receiver module, search TPMS vehicle and tire parameter table obtaining the module of corresponding temperature and pressure threshold values, the temperature and pressure threshold values information information that is sent to that described operating parameter setting module also has the correspondence that will find receives the module with processing module.
Man-machine interface in the technical program only is used for showing relevant information and reporting to the police and use, the input of the information such as type of buying car in installments is then realized by the In-vehicle networking receiver module, equally, the operating parameter setting module then can be moved automatically, search TPMS vehicle and tire parameter table to obtain suitable temperature and pressure threshold values information, and this information information that is sent to received and processing module, receive and processing module is used for information.
In like manner, the above comprise at least the vehicle condition information of vehicle also comprise with the adaptive tyre model of vehicle and season information.
The described vehicle condition information of vehicle that comprises at least also comprises traffic information or vehicle load information.
In addition, described operating parameter setting module of the present utility model also has by wired or wireless mode and the server that is positioned at high in the clouds and carries out data exchange with the temperature and pressure threshold values that upgrades vehicle condition information and be suitable for or the update module of TPMS vehicle and tire parameter table.
In case TPMS vehicle and tire parameter table on the server of high in the clouds upgrade, and will download to automatically in the operating parameter setting module by wired or wireless mode, replace original temperature and pressure threshold values or parameter list.
The operating parameter setting module can be directly downloaded TPMS vehicle and tire parameter table or is passed through the temperature and pressure threshold values of network settings from network; Also can be: by earlier downloading TPMS vehicle and tire parameter table or the temperature and pressure threshold values by network settings from network as the equipment such as ECU on computer, specific peripheral handheld device, vehicle-mounted computer, on-vehicle host or the In-vehicle networking, and then the TPMS vehicle of download and tire parameter table or the temperature and pressure threshold values by network settings transferred to the operating parameter setting module again by wired or wireless mode.
