Embodiment 1

[0054] see figure 1 , figure 1 It is a schematic flow chart of the vehicle remote control method realized by antenna orientation disclosed in the embodiment of the present invention; figure 1 As shown, a vehicle remote control method realized by antenna orientation may include:

[0055] 101. The keyless controller detects the current position of the vehicle and acquires its relative distance from the vehicle in response to a control command input by the user for controlling the door lock of the vehicle.

[0056] In the embodiment of the present invention, the keyless controller configured for the vehicle is also called an electronic smart key. The keyless controller includes a microprocessor (Microcontroller Unit, MCU). The MCU realizes the embodiment of the present invention by reading the stored instructions.

[0057] Further, the keyless controller also includes a low-frequency transmitter circuit, a low-frequency transmitting antenna, a low-frequency receiving circuit,...

Embodiment 2

[0072] see image 3 , image 3 Another schematic flow chart of the vehicle remote control method realized by antenna orientation disclosed in the embodiment of the present invention; image 3 As shown, a vehicle remote control method realized by antenna orientation may include:

[0073] 301. The keyless controller collects the user's fingerprint and transmits a first low-frequency radio frequency signal in response to a control command input by the user for controlling the vehicle door lock. The first low-frequency radio frequency signal carries the user's fingerprint and the vehicle identification.

[0074] In the embodiment of the present invention, when the keyless controller responds to the control command, it collects the user's fingerprint at the same time, and uses the user's fingerprint to enhance the safety management of the vehicle. Wherein, a fingerprint collection device is provided in the keyless controller, and the keyless controller collects the user's fingerpri...

Embodiment 3

[0089] see Figure 4 , Figure 4 The vehicle remote control system realized by antenna orientation disclosed in the embodiment of the present invention; as Figure 4 As shown, a vehicle remote control system realized by antenna orientation may include:

[0090] The keyless controller 410 is configured to detect the current position of the vehicle and acquire the relative distance between the keyless controller 410 and the vehicle in response to a control command input by the user for controlling the door lock of the vehicle;

[0091] The keyless controller 410 is also used to control the built-in antenna to emit a beam in a first direction according to the current position and the relative distance, and the beam in the first direction covers the current position;

[0092] The keyless controller 410 is further configured to encrypt the control instruction with a dynamic encryption factor, and transmit the encrypted control instruction to the vehicle controller of the vehicle ...

Abstract

The embodiment of the invention relates to the technical field of electronic vehicle control, and discloses a method and system for achieving remote control over a vehicle through antenna orientation.The method comprises the steps that a key-free controller responds to a control instruction which is input by a user and used for controlling a vehicle door lock, the current position of the vehicleis detected, and the relative distance between the key-free controller and the vehicle is obtained; the key-free controller controls a built-in antenna to transmit a first-direction wave beam according to the current position and the relative distance, wherein the current position is covered with the first-direction wave beam; the key-free controller encrypts the control instruction by using dynamic encryption factors, and the encrypted control instruction is transmitted to a vehicle controller by using the first-direction wave beam; the vehicle controller controls the vehicle door lock according to the encrypted control instruction. When the embodiment is implemented to adjust the signal transmission distance and enhance the signal intensity, the instruction receiving capacity of the vehicle controller is easily improved, and the effective remote control over the vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle electronic control, in particular to a vehicle remote control method and system realized by antenna orientation. Background technique [0002] The vehicle industry is in a stage of rapid development, and has entered people's family life as one of the necessities of life for people to travel. With the development of the intelligent era and people's requirements for vehicle intelligence are getting higher and higher, the keyless controller for remote vehicle control meets part of people's requirements for intelligence. The existing keyless controllers and vehicle controllers mostly use antenna coils to send and receive low-frequency radio frequency signals based on the antenna coils to complete mutual detection and identity authentication, as well as the control of the vehicle by the keyless controller. However, the beam emitted by the antenna coil The coverage is relatively limited. For example, t...
