Vehicle and unlocking method and device thereof

Abstract

The invention discloses a vehicle and an unlocking method and device thereof. The vehicle comprises multiple Bluetooth modules. The method comprises the following steps of obtaining a signal strengthindication value corresponding to each Bluetooth module; obtaining the distance between a terminal and the vehicle and the position of the terminal according to each signal strength indication value;judging whether or not the terminal is in a safe unlocking area according to the distance between the terminal and the vehicle and the position of the terminal, and judging whether or not the vehiclemeets a safe unlocking condition; if it is judged that the terminal is in the safe unlocking area and the vehicle meets the unlocking condition, sending a vehicle unlocking instruction to a vehicle body control module of the vehicle so as to make the vehicle body control module unlock the vehicle according to the vehicle unlocking instruction. Therefore, by means of the method, whether or not theterminal is in the safe unlocking area can be accurately judged according to the signal strength indication values of the Bluetooth modules, and the accuracy and safety of vehicle unlocking are greatly improved.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to a vehicle, a vehicle unlocking method, a non-transitory computer-readable storage medium and a vehicle unlocking device. Background technique [0002] At present, the way to use Bluetooth technology to unlock the vehicle by the terminal is generally to install a Bluetooth module in a certain position of the vehicle, judge the distance between the terminal and the Bluetooth module according to the change of the signal strength of the Bluetooth module, and then judge the distance between the terminal and the Bluetooth module Whether the terminal is in a security unlocked area. [0003] However, because the signal strength of the Bluetooth module is greatly affected by the distance, for example, if the safe unlocking distance of the vehicle is 3 meters, if the Bluetooth module is set at the rear of the vehicle and the user is 1 meter in front of the vehicle, the detected...

[0003] However, because the signal strength of the Bluetooth module is greatly affected by the distance, for example, if the safe unlocking distance of the vehicle is 3 meters, if the Bluetooth module is set at the rear of the vehicle and the user is 1 meter in front of the vehicle, the detected If the distance between the terminal and the Bluetooth module is 4 meters, it is judged that the terminal is not in the safe unlocking area, and the user cannot unlock the vehicle through the terminal; and if the user is 1 meter behind the vehicle, the distance between the detection terminal and the Bluetooth module is 1 meter, and the judgment is made. The terminal is in a safe unlocking area, and the user can unlock the vehicle through the terminal

[0004] In the above two cases, the distance between the user and the vehicle is 1 meter, but in one of the cases, the vehicle cannot be unlocked through the terminal. Therefore, the above method cannot accurately determine the position of the terminal and the vehicle, and thus cannot accurately determine whether the terminal is safe. unlock area
