Abstract
The utility model discloses a no-key entering system which is characterized by being a main controller PSE. The main controller PSE is connected with a sensor system and a body controller BCM. The body controller outputs a control signal to a door lock control system. The no-key entering system effectively prevents non-human factors from opening vehicle doors, and on the condition that a user has a legal key, enters the search coverage of a sensor with the legal key, and presses a switch on the sensor for more than 0.3S, the main controller PSE considers the operation as the legal application for opening the vehicle doors. The whole system is low in cost and suitable for being popularized and applied in a large-scale mode.
Description
Technical field
The utility model relates to the gate control system of automobile, particularly a kind of keyless access system.
Background technology
The gate control system of automobile is the problem that each auto vendor relatively pays close attention to always; traditional automobile key often can be because loss or the damage section of key cause arrangements for automotive doors cannot open and start; if key lock itself gets clogged or destroys, be also prevented from entering vehicle.
For the security consideration of automobile, use without key chain decorations, thereby make the driving of the button on chain decorations produce infrared signal or radiofrequency signal, it is detected by the sensor in vehicle, and this sensor opposite house carries out release.But user still needs key, so that operating point ignition system.Although at present start and be applied on automobile without key, very difficultly come by popularization because cost is higher.
For the problems referred to above, a kind of lower-cost keyless access system is provided, avoiding using key direct control vehicle is the problem that prior art need to solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of keyless access system, to reach the object of avoiding using key direct control vehicle.
For achieving the above object, the technical solution of the utility model is that a kind of keyless access system, is characterized in that: described system is master controller PSE connecting sensor system and car body controller BCM respectively; Car body controller output control signal is to door lock control system.
Described sensing system is provided with Anneta module and switch module.
Described sensing system and master controller PSE are by LIN bus connecting communication.
Described car body controller BCM and master controller PSE are by CAN bus connecting communication.
A kind of keyless access system, owing to adopting above-mentioned structure, the utility model effectively prevents that non-artificial factor from causing car door opening, only has the user of legal key and carry legal key to enter switch in the search coverage of sensor and in compression sensor and be greater than that 0.3S is above can be thought that legal application opens car door by master controller PSE; Whole system cost is lower, is applicable to promoting the use on a large scale.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is the structured flowchart of a kind of keyless access system of the utility model;
In Fig. 1,1, master controller PSE; 2, car body controller BCM; 3, door lock control system; 4, sensing system; 5, Anneta module; 6, switch module.
The specific embodiment
As shown in Figure 1, to be master controller PSE1 be connected with car body controller BCM2 by CAN line the utility model, control institute's control system 3 for carrying out the enforcement of the control signal of relevant door lock; Sensing system 4 connects with master controller PSE1 by LIN line;
Sensing system 4 Anneta module 5 above starts electromagnetic radiation-emitting wave beam towards periphery after receiving the external probe command of master controller PSE1; At electromagnetic radiation as waves, flutter and grasp after the validated user that is identified agreement by master controller PSE1 by uniqueness, permit further operating; After the legitimacy of authentication of users, after the switch module 6 above compression sensor system, coherent signal can be delivered to master controller PSE1 by LIN line, thereby control, door control system 3 is locked, release action.
The utility model effectively prevents that non-artificial factor from causing car door opening, only has the user of legal key and carry legal key to enter switch in the search coverage of sensor and in compression sensor and be greater than that 0.3S is above can be thought that legal application opens car door by PSE controller.Utilize the antenna part above controller emitting electromagnetic wave drive system sensor that electromagnetic radiation wave beam is provided, search is the existence of validated user around, after the identity of validated user is verified, the action of associated drive automatic control gate lock signal, removes frequent use mechanical key from, does not meet the drawbacks such as human engineering.This scheme is with respect to traditional mechanical key, the frequent use of tradition mechanical key, plug and rotary machine lock had both easily caused the wearing and tearing of mechanical tooth, and then change, cause losing time going to process with energy, be not easy to again operation, after this programme enters this without key enter will offer convenience sense and comfort.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
Claims (4)
