Abstract
The utility model provides an automatic opening sensing device of an automobile trunk, and belongs to the field of automobile electronics. The automatic opening sensing device comprises two capacitive sensors, the capacitive sensor (1) and the capacitive sensor (2) are respectively installed on the tail portion of the automobile trunk, the capacitive sensor (1) is vertical to the horizontal plane and is installed at the upper end of a baffle on the tail portion of the automobile trunk, the capacitive sensor (2) is parallel with the horizontal plane and is installed at the lower end, close to the inner side of an automobile body, of the baffle on the tail portion of the automobile trunk, and output signals of the two capacitive sensors are both connected to the input end of a host module. When a response signal of the capacitive sensor (1) and a response signal of the capacitive sensor (2) are input into the host module simultaneously, a master control chip of the host module is waken up to work, a corresponding instruction is sent out to detect an automobile owner identity recognition module, and when the automobile owner identity recognition module feeds back a corresponding signal, the host module controls a trunk opening module to carry out opening operations.
Description
Technical field
The utility model relates to vehicle electric field, especially refers to a kind of automobile trunk intelligent-induction opening device.
Background technology
Modern society, automobile is as a kind of the most frequently used vehicle, the key propertys such as it is safe, energy-conservation, comfortable and convenient become its requisite key element and condition, the requirement of its hommization also can be more and more higher, therefore the performance that how to improve hommization is also the trend of vehicle electronics development, carries out corresponding action when how being identified in user and needing most; As the intention of identifying car owner and opening boot, particularly in the time that car owner need to put into automobile trunk article, and both hands cannot be vacateed in empty situation, intelligent opening boot.Although current existing technical scheme has infrared induction, ultrasonic fault detection, microwave remote sensor etc. automatically to open the device of boot, but owing to being easily subject to the interference of variety of event of outdoor environment, false triggering and cause car owner not to be intended to open in the situation of boot automatically opening boot; Or occur that car owner is not nearby time, be subject to the interference of accident, the frequent output signal of sensing device wakes main control chip work up, cause main control chip and other interlock circuit work, make working power in unnecessary loss, cause period of service to shorten, when for a long time in such situation, there will be power supply to exhaust, in the time that car owner needs automatically to open boot, and occur the situation that can not automatically open boot.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile trunk automatically to open induction installation.
For achieving the above object, the solution that the utility model is taked is: automobile trunk is opened induction installation automatically, it comprises 2 capacitive transducers, capacitive transducer (1) is arranged on automobile trunk afterbody baffle plate upper end perpendicular to horizontal surface, capacitive transducer (2) is parallel to horizontal surface and is arranged on inclined to one side vehicle body inner side, automobile trunk afterbody baffle plate lower end, and 2 capacitive transducer output signals are all received host module input end.When capacitive transducer (1) and capacitive transducer (2) have response signal to input to host module simultaneously, host module main control chip wakes work up, send command adapted thereto inspection vehicle owner identification identification module (PKE), when vehicle owner identification module (PKE) is correctly fed back corresponding signal, host module control boot opening module is carried out breakdown action.
When capacitive transducer (1) and capacitive transducer (2) all have response signal to input to host module, the main control chip of host module is waken up work.In the time only having a capacitive transducer to have induced signal, main control module receives only signal, does not do response and wakes work up, thereby overcome external interference source (as animal, rainwater etc.) and cause the problem of false triggering; Meanwhile, can also avoid the disturbed source of main control module constantly to wake up, constantly searching vehicle owner identification identification module (PKE) signal, and cause the loss of unnecessary working power, reach certain energy-conservation object.
Brief description of the drawings
Fig. 1 is the induction range schematic diagram of the capacitive transducer of the present embodiment.
Fig. 2 is the installation site index map of the capacitive transducer of the present embodiment.
Fig. 3 is the structured flowchart of the present embodiment.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is remake to description.
Referring to Fig. 1 and Fig. 2, automobile trunk is automatically opened induction installation and is comprised 2 capacitive transducers, capacitive transducer (1) and capacitive transducer (2) are arranged on respectively automobile trunk afterbody, wherein capacitive transducer (1) is arranged on automobile trunk afterbody baffle plate upper end perpendicular to horizontal surface, and capacitive transducer (2) is parallel to horizontal surface and is arranged on inclined to one side vehicle body inner side, automobile trunk afterbody baffle plate lower end.
Referring to Fig. 3, capacitive transducer (1) and capacitive transducer (2) output signal are received host module input end, host module and vehicle owner identification module (PKE) signal bidirectional transmission, the unidirectional output control of host module boot opening module.
Principle of work: when capacitive transducer (1) and capacitive transducer (2) have response signal to input to host module simultaneously, host module main control chip wakes work up, host module sends identification signal inspection vehicle owner identification identification module (PKE), vehicle owner identification module (PKE) receives that signal feeds back corresponding information to host module, host module is checked all signals and is carried out after respective handling, and output is controlled boot opening module and carried out breakdown action.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, nobody near and while having foot below boot, when capacitive transducer (1) and capacitive transducer (2) do not have response signal to input to host module, the main control chip of host module is in dormancy low power consumpting state.In the time that car owner needs automatically to open boot work, human body is near automobile trunk, and there is foot to make corresponding actions, when capacitive transducer (1) and capacitive transducer (2) have response signal to input to host module simultaneously, the main control chip of host module is waken up work, send command adapted thereto inspection vehicle owner identification identification module (PKE), when vehicle owner identification module (PKE) is correctly fed back corresponding signal, host module control boot opening module is carried out breakdown action.
