Description

Automobile central control system and control method for automatic door unlocking

technical field

The invention relates to the automobile control technology, in particular to the control technology for controlling the door switch in the automobile central control system.

Background technique

At present, many cars have PKE automatic induction door opening and closing system. The car owner takes the car remote control, walks to the side of the car, presses the car door handle switch, or reaches out to the door handle. Open the car door. The moment the owner opens the door (or press the switch on the door handle, or reach out to the door handle area and be sensed by the sensor), the system determines whether to unlock the door by detecting whether the remote control carried by the owner is legal. However, if the owner forgets to bring the remote control, the door cannot be opened. In addition, during the sale of cars, some car owners hope to install upgraded anti-theft and remote start systems. If you want to start the car remotely, the car computer must detect the legal key before starting, so you must put the original car remote control in the car, when you want to start the car remotely, add power to the car remote control, so that the car When the computer detects that the original car key is in the car, the car can be started remotely. But in doing so, the car owner will lose a remote control, and the added product must be re-made with a PKE system different from the original car system, and then equipped with an additional remote control different from the original car system for the car owner, which is a waste of money. Inconvenient, and the system is often unstable.

Contents of the invention

The present invention provides an automobile central control system and a control method of the central control system, which adopts the method of adding a Bluetooth module, and controls the central control system by verifying the identity of the owner's mobile phone, so as to solve the technical problem of inconvenient vehicle modification in the prior art .

The solution designed by the present invention to solve the above-mentioned technical problems is: the central control system includes a control system, and also includes a Bluetooth module connected to the control system, and further includes a detection control module connected to the data interface of the automobile driving computer, and the detection control module is connected to the control system described above. The automatic door unlocking control method of this central control system includes the following steps: A. Install a Bluetooth module in the vehicle control system, and the wireless communication device is a mobile phone, PDA or IPAD; B. Use a wireless communication device with Bluetooth function to communicate with the Bluetooth module. The module is paired, and the communication relationship is established. The feature code of the wireless communication device is stored in the Bluetooth module; When someone tries to open the door, send a door-opening command to the central control system; D. The central control system unlocks the vehicle door according to the door-opening command.

When the Bluetooth module senses that the wireless communication device approaches the vehicle for a long time or multiple times, it detects the signal of the door handle.

The invention provides a new control method. When the car owner forgets to bring the remote controller, he can obtain authentication through the mobile phone, which is convenient for users to use. For the refitted car, the original system does not need to be disassembled to avoid affecting the original car.

Description of drawings

Fig. 1 is a schematic diagram of the central control system of the present invention.

Detailed ways

The specific embodiment of the present invention is described in conjunction with accompanying drawing 1.

As can be seen from Fig. 1, this automobile central control system 1 of the present invention includes a control system 2, also includes a bluetooth module 3 connected to the control system, and further includes a detection control module 6 connected to the data interface of the automobile driving computer, the detection control module Connect the control system. The control method of this central control system car door automatic unlocking comprises the following steps: A. Install a Bluetooth module in the car control system, and the wireless communication device is a mobile phone 4, PDA or IPAD; the Bluetooth module can be directly installed in the car In the control system, the controller of the Bluetooth module can also be connected with the driving computer system; B. Use a wireless communication device with Bluetooth function to pair with the Bluetooth module to establish a communication relationship, and the Bluetooth module stores the feature code of the wireless communication device C. When the Bluetooth module senses that the wireless communication device is close to the vehicle, it detects the signal of the original door handle sensor through the vehicle driving computer system, and sends an instruction to the central control system to open the door when it detects that someone is trying to open the door; The bluetooth module is installed in the central control system, and the bluetooth module sends the door opening command directly to the central control system. The central control system forwards the command to open the door. D. The central control system unlocks the vehicle door lock 5 according to the door opening instruction.

Through the authentication relationship between the bluetooth module and the mobile phone, the invention can open the car door and start the car for the car owner when the car owner forgets to carry the remote controller, which greatly facilitates the car owner. The central control system of the present invention extracts the sensor signal provided at the door handle from the COBUS bus of the automobile driving computer. When the sensor has a signal output, it means that the car owner is ready to open the car door. At this time, the central control system sends a door opening instruction. The key point is to use the sensor at the door handle of the original car. It is not necessary to replace a door handle and rebuild a PKE system as in the prior art. On the one hand, it saves manpower and material resources; Possible problems such as incompatibility or partial program conflicts can fully guarantee the effect and safety of vehicle modification.

Also to ensure the safety of the vehicle, in step C of the present invention, when the Bluetooth module senses that the wireless communication device has been close to the vehicle for a long time or multiple times, it detects the signal of the door handle and sends an instruction to open the door to the central control system.

The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.
