The invention provides a method, device and
system for vehicle intelligent unlocking. The method in one embodiment comprises the steps that when a whole vehicle is in a locked state, antennas arranged on the vehicle are controlled to sent low-frequency signals; a first response
signal returned when a vehicle intelligent key receives the low-frequency signals of the antennas is received, and the first response
signal comprises the
signal strength, detected by the vehicle intelligent key, of the antennas; the area where the vehicle intelligent key is located is determined according to the
signal strength of the antennas in the first response signal; when the vehicle intelligent key is located in a meeting area, intelligent key pre-
authentication is carried out on the vehicle intelligent key, and prompting information is sent after intelligent key pre-
authentication succeeds; and when the vehicle intelligent key is close to an unlocking area, intelligent
key authentication is carried out on the vehicle intelligent key, the whole vehicle is controlled to be unlocked after intelligent
key authentication succeeds, and after the whole vehicle is unlocked, and when any vehicle door of the vehicle is in an opened state, the antennas are controlled to stop sending the low-frequency signals. According to the method, device and
system for vehicle intelligent unlocking, the use experience of vehicle users is improved, and convenience is improved.
