Description

Vehicle control method and system and vehicle
Technical Field
The invention relates to the technical field of automobiles, in particular to a vehicle control method and system and a vehicle.
Background
At present, a PEPS (Passive Entry Passive Start) of a vehicle is fully applied to a passenger vehicle, and a passenger only needs to carry a vehicle key with him or her and does not need to take out the vehicle key to pull a door handle to enter the vehicle; or directly press a key start switch in the car, can start the vehicle, saved old-fashioned ignition device's the operation of rotatory mechanical key ignition, consequently brought the good experience of convenience and science and technology sense for the customer.
Meanwhile, with the heavy use of user terminals such as mobile phones in daily life, people are more and more unable to leave mobile phones. The mobile phone Bluetooth technology is also integrated into a PEPS system, and the trend of the PEPS technology development is formed by unlocking the car door and starting the car through the mobile phone. The technology is realized by part of vehicles at present.
At present, the following schemes are mainly used for controlling the vehicle through a mobile phone:
1. the mobile phone is communicated with the vehicle networking controller through the 4G, and the vehicle networking controller controls unlocking and starting of the vehicle. The user needs to operate APP software in the mobile phone to perform vehicle operations. The mobile phone of the scheme is similar to the original remote control key. One of the defects is that the keyless entry and the starting cannot be realized, and all the functions are realized by operating a mobile phone; the other disadvantage is that the system needs mobile network support, and the system cannot work or has larger delay at the place with poor network signal, namely the signal is unstable;
2. the mobile phone is communicated with the Bluetooth module in the vehicle through Bluetooth for verifying the identity of a vehicle owner and realizing the functions of keyless entry and keyless start, but the current Bluetooth technology cannot achieve the accuracy of a low-frequency antenna, the positioning error of the Bluetooth technology is calculated by meters, and meanwhile, when the mobile phone encounters the barriers of human bodies, water and other objects, the error is larger, so that the abnormity of the functions of keyless entry and keyless start is caused, namely the accuracy is not high. For example, the mobile phone is arranged in a vehicle, and the vehicle can be locked outside the vehicle; or the greeting is close or far away. If a plurality of Bluetooth antennas are adopted to enhance the positioning accuracy, the cost is greatly increased, and the economy is poor;
3. because the Bluetooth is positioned inaccurately, the hidden danger of property safety is brought to the use of the vehicle owner. When the mobile phone is near the vehicle, the owner of the vehicle may unlock the vehicle unintentionally, and only around the vehicle, other people may unlock the vehicle, even start the vehicle, and operate the vehicle, so that the safety is not high.

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a control method of a vehicle according to one embodiment of the invention.
First, a vehicle related to the method will be described with reference to fig. 2. Specifically, as shown in fig. 2, the vehicle includes, for example, a bluetooth car for determining the location of the user terminal according to a bluetooth signal sent by the user terminal, and one or more low-frequency antennas for searching a radio-frequency signal sent by a vehicle key to determine the location of the vehicle key.
The user terminal is, for example, an intelligent terminal held by a user, such as a mobile phone, and the user terminal can communicate with the vehicle-mounted bluetooth, and further, the vehicle-mounted bluetooth determines the position of the mobile phone according to a bluetooth signal sent by the mobile phone, so that the user terminal, that is, the user, is positioned.
The vehicle-mounted Bluetooth module is, for example, a low-power Bluetooth module, is arranged on a vehicle, and is used for sending and receiving Bluetooth signals, processing the Bluetooth signals, and realizing the positioning of the user terminal.
In the embodiment of the present invention, the vehicle key refers to an article capable of receiving and transmitting a radio frequency signal, such as a bracelet, or an ornament, or a radio frequency card, and may also be in the shape of other portable articles, and is not a smart key of a single-finger conventional system.
The low-frequency antenna is arranged on the vehicle and used for determining the position of the vehicle key according to the radio-frequency signal sent by the vehicle key, namely realizing the positioning of the vehicle key.
The PEPS controller is a keyless entry and start controller and is mainly responsible for keyless entry and start logic processing.
Based on this, as shown in fig. 1, a control method of a vehicle according to one embodiment of the present invention includes the steps of:
step S1: and judging whether the position of the user terminal enters a first preset area or not. Specifically, referring to fig. 3, the first preset area is an area a in the drawing, that is, the position of the user terminal is determined according to a bluetooth signal sent by the user terminal through the vehicle-mounted bluetooth, and it is determined whether the user terminal enters the first preset area a. Since the user terminal is a device carried by the user, it is also determined whether the user enters the first preset area a.
Step S2: if so, judging whether the position of the vehicle key enters a second preset area or not, wherein the second preset area is contained in the first preset area. Specifically, referring to fig. 3, when it is determined that the user terminal enters the first preset area a, the second preset area B is an area in the drawing, that is, when it is determined that the user terminal enters the first preset area a, the radio frequency signal sent by the vehicle key is further searched through the low frequency antenna to determine the position of the vehicle key, and it is determined whether the vehicle key enters the second preset area B. The coverage area of the first preset area A is relatively large, the coverage area of the second preset area B is relatively small, and the second preset area B is contained in the first preset area A.
Step S3: if yes, controlling the vehicle to unlock and sending unlocking prompt information. That is, when it is determined that the vehicle key enters the second preset area B, which indicates that the user is approaching the vehicle at this time, the vehicle is controlled to unlock, and an unlocking prompt message is sent, for example, the vehicle turn light is controlled to flash, so that the vehicle welcome function is realized. Further, when the user operates the start function, the vehicle key is firstly searched, and when the key in the vehicle is detected, the vehicle can be started.
Further, after the low frequency antenna searches for the radio frequency signal emitted by the vehicle key, the method further comprises: verifying the radio frequency signal to judge whether the vehicle key is legal or not; and if the vehicle key is legal, further judging whether the vehicle key enters a second preset area. That is, through the verification of the radio frequency signal, whether the vehicle key corresponds to the user vehicle is determined. For example, when a vehicle is in a parking lot, a plurality of radio frequency signals sent by vehicle keys of other vehicle owners may be received, so that the radio frequency signals need to be verified to judge whether the corresponding vehicle key is of the vehicle, if so, the vehicle key is judged to be legal, if not, the vehicle key is judged to be illegal, the radio frequency signals are ignored, and therefore, the situations of mistaken unlocking and the like are prevented, and the safety and the reliability of keyless starting are improved.
Further, the method further comprises: when the duration time of the radio-frequency signals sent by the low-frequency antenna searching vehicle key reaches the preset time, the low-frequency antenna is controlled to stop searching the radio-frequency signals, and therefore the situation that the static current is too large due to continuous work of the system and the whole vehicle is lack of power is prevented.
Further, the method further comprises: after the vehicle is flamed out, judging whether the position of the vehicle key leaves a second preset area or not; if so, judging whether the position of the user terminal leaves a first preset area or not; if yes, controlling the vehicle to be locked and sending locking prompt information. Specifically, after the vehicle is parked and flameout, whether the position of the vehicle key leaves the second preset area B or not is judged if the intention of the user to leave is shown, if so, whether the position of the user terminal leaves the first preset area A or not is further judged if the intention of the user to leave is shown, namely, the user does not use the vehicle temporarily, the vehicle is controlled to be locked, and locking prompt information is sent out, for example, the turn light is controlled to flash and/or the horn is controlled to sound.
Further, the method further comprises: receiving a vehicle starting instruction or a locking instruction sent by a user terminal, and judging whether the position of the user terminal is in a third preset area; and if so, responding to a vehicle starting command or a locking command, wherein the third preset area is contained in the first preset area. Specifically, a user operates a relevant option or button on the user terminal to issue a vehicle start instruction or a vehicle lock instruction, which indicates the unlocking intention or the vehicle locking intention of the user, at this time, it is determined whether the position of the user terminal is in the third preset region C, for example, as shown in fig. 3, if so, the vehicle start instruction or the vehicle lock instruction is responded, that is, the vehicle is controlled to be unlocked and started or locked, and an unlocking prompt message or a locking prompt message is issued. The third preset area C is included in the first preset area a, specifically, for example, included in the vehicle, that is, when the user operates the vehicle to unlock or lock in the vehicle through the user terminal, the corresponding unlocking or locking operation may be performed. Namely, the user can complete the unlocking starting and locking functions of the vehicle through the user terminals such as the mobile phone and the like.
Referring to fig. 3, for example, the position of the user terminal is determined through the low-power-consumption vehicle-mounted bluetooth, when the user terminal enters the first preset area a from a distance, the low-frequency antenna starts to search for a radio frequency signal sent by the vehicle key in the second preset area B to determine the position of the vehicle key, and when it is determined that the vehicle key enters the second preset area B, the vehicle is unlocked, and the turn light is blinked to complete the welcome function. Further, when the user leaves the vehicle after flameout, when the fact that the vehicle key leaves the second preset area B is detected, and when the fact that the user terminal leaves the first preset area A is detected, the vehicle is locked, the turn light flickers or the vehicle horn buzzes. In a specific embodiment, the welcome function can be configured to be turned on or off through the user terminal. In other words, when the user is ready to enter the vehicle, the Bluetooth is activated firstly when the user enters the A range, the PEPS system is activated through the Bluetooth, the PEPS system drives the low-frequency antenna to find the vehicle key, if the user carries the key, the welcome function is achieved, the vehicle is unlocked, and if the user does not carry the vehicle key, the user can unlock the vehicle through the user terminal. When a user leaves the vehicle, the low-frequency antenna is driven to search for a vehicle key, whether the user leaves the area B is judged, then the Bluetooth is driven to judge whether the user leaves the area A, when the user leaves the area A with the user terminal and the vehicle key leaves the area B, the PEPS system achieves an automatic locking function, locks the vehicle, and flicks a turn light or sounds a horn and the like to prompt the user. The process of driving the low-frequency antenna can set overtime time T (namely preset time), and when the search time exceeds the preset time T, the search for the vehicle key is stopped, so that the condition that the static current is too large due to the continuous work of a system, and the power loss of the whole vehicle is caused is prevented.
In conclusion, the control method of the vehicle adopts a mode of combining the Bluetooth and the low-frequency technology, avoids the problem of poor positioning of the Bluetooth, and makes up for the defect of poor positioning precision by using the low-frequency technology, so that the welcome function and the leaving automatic locking function of the vehicle can be accurately finished. On the other hand, an overtime protection strategy is set, and the condition that the whole vehicle function is influenced due to the fact that the whole vehicle is insufficient in power because the vehicle key is continuously searched is prevented.
According to the vehicle control method provided by the embodiment of the invention, the position of the user terminal is determined through the vehicle-mounted Bluetooth, the position of the vehicle key is determined through the low-frequency antenna, and when the position of the user terminal enters the first preset area and the position of the vehicle key enters the second preset area, the vehicle is controlled to be unlocked and unlocking prompt information is sent out, so that keyless entry of the vehicle can be realized through the user terminal and the Bluetooth, convenience is provided for a user, the signal stability and the positioning accuracy are improved through a mode of combining the Bluetooth and the low-frequency technology, the required cost is low, and the user experience is improved.
