A method and device for opening the trunk of a car with an induction trigger

Abstract

The invention provides a sensing trigger automotive trunk opening method and device, and belongs to the technical field of automobiles. By means of the method and the device, the problems that an existing trunk is likely to be opened by mistake and the power consumption is large are solved. The method comprises the steps that a triggering signal is detected by a detection sensor; based on the triggering signal, a trunk controller is awakened, and the trunk controller sends a first verification signal to awaken a transponder; the first verification signal is verified by the transponder, a second verification signal is fed back to the trunk controller after the first verification signal passes verification, and the trunk controller verifies the second verification signal; after the second verification signal passes verification, the trunk controller controls the trunk to be opened. The device comprises the transponder, the trunk controller, the detection sensor and a trunk door lock motor, wherein both the detection sensor and the trunk door lock motor are electrically connected with the trunk controller, and the trunk controller wirelessly communicates with the transponder. By meansof the method and the device, the condition that the trunk is opened by mistake can be reduced, the power consumption of the transponder and the trunk controller can be significantly reduced, and theservice life of the transponder is significantly prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an induction trigger type automobile trunk opening method and device. Background technique [0002] The current methods of opening the trunk of a car include remote control outside the car and induction opening, and the control systems of both include a signal transmitting device, a control device, a processing device and an execution unit. [0003] Wherein, the remote control trunk opening method is a one-way signal transmission, pressing a button is equivalent to transmitting a signal, and the control device only needs to receive such a signal, and open the trunk after processing. This mode requires the user to take out the key and press the button, and when the user holds the item, the remote control opening method is very inconvenient. [0004] The trunk induction opening device meets the development requirements of keyless operation of the car. At present, the trunk induc...

Problems solved by technology

[0007] This invention still has the following deficiencies: 1. The electronic car key of this invention does not need to verify the signal received from the vehicle, that is, feed back the safety information stored in the electronic car key to the vehicle, which will easily cause security information leakage and power consumption of the electronic car key. 2. As long as the electronic car key holder is close to the rear of the vehicle, the vehicle will activate the vehicle to send signals to the electronic car key, which will cause the signal to be sent too frequently, and cause the vehicle control to always match the feedback of the electronic car key Information will eventually cause data redundancy and increase the burden on the car controller; 3. In real life, if the holder of the electronic car key happens to pass by the designated location after parking, the car controller will also make a misjudgment and cause the trunk to open. Instead, it has caused trouble for electronic car key holders
