Problems solved by technology

The wireless frequency band used in the unlocking process of the smart key is fixed, and the wireless unlocking code carried in the wireless frequency band is also fixed and single. Therefore, although the smart key is easy to use, the wireless unlocking code of the vehicle is relatively easy to crack, and there are potential safety hazards. It is easier to crack the corresponding vehicle smart key

Embodiment Construction

[0035] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.

[0036] See figure 1 The embodiment of the present invention discloses a method for controlling the opening of the trunk of an automobile, which is characterized in that it includes:

[0037] Determine whether the smart key of the vehicle is detected, and whether the distance between the smart key and the vehicle is less than the preset distance;

[0038] If the smart key of the vehicle is detected and the distance between the smart key and the vehicle is less than the preset distance, the laser transmitter installed at the rear of the vehicle can be enabled to project multiple light spots on the ground at the rear of the vehicle;

[0039] According to whether the output signal of the sensor corresponding to each light spot jumps, and the number ...

Abstract

The invention discloses a car trunk opening control method and system. The car trunk opening control method comprises: determining whether a smart key of a car is detected and whether a distance between the smart key and the car is smaller than a preset distance; if yes, enabling a laser emitter arranged at the tail of the car to project a plurality of light spots on the ground below the tail of the car; calculating an unlocking code that a user blocks the light spots according to whether an output signal of a sensor corresponding to each light spot jumps, and a count and a time sequence of jumps; determining whether the unlocking code is consistent with an unlocking code prestored in the car; if yes, unlocking the car trunk; and if not, not unlocking the car trunk. The car door unlocking method and system provided by the present invention are convenient to use, and have an extremely high safety level.

Description

Technical field [0001] The invention relates to the field of automobile safety, in particular to a method and system for controlling the opening of the trunk of an automobile. Background technique [0002] Compared with the compartment, the car trunk is a safer part, and it is also the most common place for valuables in the car. Existing car trunks are mainly unlocked with a mechanical key or wirelessly with a smart key. The wireless frequency band used in the process of unlocking the smart key is fixed, and the wireless unlocking code carried in the wireless frequency band is also fixed and single. Therefore, although the smart key is convenient to use, the wireless unlocking code of the vehicle is relatively easy to crack, which poses security risks. It is easier to crack the corresponding vehicle smart key. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a simple and safer method for controlling the opening of t...
