Accompanying drawing explanation
Fig. 1 is control block diagram of the present utility model;
Fig. 2 is the X of antenna, Y, and tri-directions of Z are carried out scintigram.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described, following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the concrete technical scheme of implementing of the utility model is: a kind of automobile keyless access system, this system is based on automobile front engine, the positive assistant driver seat part of automobile, auto rear seat part, boot, rear bumper, left front door, right front door, left back door and right-rear-door, and this system comprises control module, directions X antenna, Y-direction antenna and Z directional aerial;
Its annexation is: described directions X antenna, Y-direction antenna and Z directional aerial are connected with control module;
Described control module is used for receiving sweep signal and sweep signal is sent to respectively to directions X antenna, Y-direction antenna and Z directional aerial;
Described control module is by the directions X of directions X antenna scanning automobile front engine, the positive assistant driver seat part of automobile, auto rear seat part, boot, rear bumper, left front door, right front door, left back door and right-rear-door;
Described control module is by the Y-direction of Y-direction antenna scanning automobile front engine, the positive assistant driver seat part of automobile, auto rear seat part, boot, rear bumper, left front door, right front door, left back door and right-rear-door;
Described control module is by the Z direction of Z directional aerial scanning automobile front engine, the positive assistant driver seat part of automobile, auto rear seat part, boot, rear bumper, left front door, right front door, left back door and right-rear-door.
The power of described directions X antenna, Y-direction antenna and Z directional aerial is 1～2A.
Total coverage of described directions X antenna, Y-direction antenna and Z directional aerial is 4～5 meters.
The utility model is mainly to use the antenna of less amount to complete same function, and according to the principle of antenna scanning, has carried out the optimization of technology.
By Fig. 1, can clearly find out that antenna is normal key position how, then keyless access system will be realized different functions according to the different position of key.
The utility model adopts more powerful low-frequency antenna, aerial power rises to 1A or even 2A from current 600mA left and right, the lifting of key end low-frequency sensitive degree is brought up to 0.375-0.25mV from current 1mV, wide (4～5 meters of this antenna footprint, can cover in whole car and car outer) and cost increase little, and can save an indoor antenna and four grip handle antennas, based on this technology, can well realize Intelligent greeting system.
