Vehicle control method and system and vehicle

Abstract

The invention provides a vehicle control method and system and a vehicle. The vehicle comprises vehicle-mounted Bluetooth and one or more low-frequency antennas, wherein the vehicle-mounted Bluetoothis used for determining the position of a user terminal according to a Bluetooth signal sent by the user terminal; and the low-frequency antennas are used for searching for a radio frequency signal sent by a vehicle key so as to determine the position of the vehicle key. The method comprises the following steps that whether the position of the user terminal enters a first preset area or not is judged; if yes, whether the position of the vehicle key enters a second preset area or not is judged, wherein the second preset area is contained in the first preset area; and if yes, the vehicle is controlled to be unlocked, and unlocking prompt information is sent. According to the method, keyless entry of the vehicle can be achieved through the user terminal and the Bluetooth, convenience is provided for a user, through the mode that the Bluetooth and the low-frequency technology are combined, the signal stability and the positioning accuracy are improved, the needed cost is low, and the userexperience is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, system and vehicle. Background technique [0002] At present, vehicle PEPS (Passive Entry Passive Start, keyless entry and start system) has been fully applied in passenger cars. Passengers only need to carry the vehicle key with them, and can pull the door handle to enter the vehicle without taking out the operation; or The vehicle can be started by directly pressing the one-button start switch in the car, which saves the operation of rotating the mechanical key to ignite the old-fashioned ignition device, thus bringing customers a good experience of convenience and sense of technology. [0003] At the same time, with the heavy use of user terminals such as mobile phones in people's daily life, people's lives are increasingly inseparable from mobile phones. Mobile phone Bluetooth technology has also been integrated into the PEPS system. Unlocking t...

AI Technical Summary

Problems solved by technology

One of the disadvantages is that it is impossible to achieve keyless entry and start, and everything must be realized by operating the mobile phone; the second disadvantage is that the system needs mobile network support, and the system cannot work in places with poor network signals or the delay is large, that is, the signal is unstable;

[0006] 2. The mobile phone communicates with the Bluetooth module in the vehicle through Bluetooth to verify the identity of the owner, and then realize the functions of keyless entry and keyless start. However, the current Bluetooth technology cannot achieve the accuracy of low-frequency antennas, and the positioning error of Bluetooth technology is calculated in meters. At the same time, when encountering obstacles such as human body and water, the error will become larger, which will cause abnormal keyless entry and keyless start functions, that is, the accuracy is not high

If multiple Bluetooth antennas are used to enhance positioning accuracy, the cost will be greatly increased and the economy will be poor;

[0007] 3. Due to the inaccurate positioning of Bluetooth, it brings hidden dangers to property safety for car owners.

When the mobile phone is near the vehicle, the owner may not intend to unlock the vehicle, but only around the vehicle, other personnel can unlock the vehicle, even start the vehicle, and operate the vehicle, so the security is not high
