Fig. 3 is a flowchart illustrating a method of locating a tire pressure sensor according to an exemplary embodiment. In this exemplary embodiment, the detection range of each signal detector covers only its adjacent wheels. Taking a four-wheel automobile as an example, the detection range of the signal detector positioned on one side of the left front wheel only covers the area where the left front wheel is located, the detection range of the signal detector positioned on one side of the left rear wheel only covers the area where the left rear wheel is located, the detection range of the signal detector positioned on one side of the right front wheel only covers the area where the right front wheel is located, and the detection range of the signal detector positioned on one side of the right rear wheel only covers the area where the right rear wheel is located.
As shown in fig. 3, the tire pressure sensor positioning method is used in a controller of a target vehicle, and is automatically performed when the vehicle is powered on, and the embodiment includes the steps of:
in step 301, it is determined that the tire pressure sensor acknowledgement information transmitted by the at least one signal detector is obtained when the tire pressure sensor acknowledgement information transmitted by the at least one signal detector is continuously received within a first preset time period.
By continuously receiving the tire pressure sensor confirmation information transmitted from the at least one signal detector for the first preset time period, the stability of the signals transmitted from the signal detectors, each of which detects one tire pressure sensor, may be ensured to better confirm that the target vehicle has the at least one tire pressure sensor.
Before each tire pressure sensor is connected with the controller, signals carrying identification marks are continuously transmitted at a fixed frequency, the signal detectors detect the signals transmitted by the tire pressure sensors in real time, and the at least one signal detector continuously receives the signals carrying the identification marks in a first preset time period, namely, the at least one signal detector continuously transmits confirmation information in the first preset time period, so that the signals of the tire pressure sensors stably exist on a target vehicle, namely, the target vehicle can be confirmed to have the tire pressure sensors with the identification marks, and the confirmation information is transmitted to the controller.
Optionally, the first preset time period is at least 20 seconds.
In step 302, the number of received tire pressure sensor acknowledgement information is determined based on the tire pressure sensor acknowledgement information transmitted by the at least one signal detector.
According to the received tire pressure sensor confirmation information sent by the signal detector, the quantity of the received tire pressure sensor confirmation information can be determined, and the quantity of the tire pressure sensors to be positioned can be further determined conveniently according to the quantity of the confirmation information.
The tire pressure sensor confirmation information comprises the identification mark of the tire pressure sensor, and the tire pressure sensor carrying the identification mark can be determined to be located on the target vehicle through the identification mark of the tire pressure sensor.
In step 303, the number of tire pressure sensors to be positioned is determined based on the number of received tire pressure sensor confirmation information.
Since each signal detector detects one tire pressure sensor, the number of tire pressure sensors that can be positioned can be determined by the number of received tire pressure sensor confirmation messages. And the number of the existing tire pressure sensors is determined, so that the positioning of each tire pressure sensor to be positioned is convenient to realize.
For example, when the number of received tire pressure sensor confirmation information is three, it may be determined that the target vehicle has three tire pressure sensors.
In step 304, a wheel position corresponding to each tire pressure sensor is determined based on the tire pressure sensor confirmation information transmitted by each signal detector.
Since the tire pressure sensor confirmation information includes the identification of the tire pressure sensor, and each signal detector has the corresponding set position information, the wheel position corresponding to the tire pressure sensor can be determined by combining the identification of the tire pressure sensor and the set position information of the signal detector that detects the tire pressure sensor.
It will be appreciated that each signal detector has setup location information indicative of its setup location.
For example, in response to acquiring the confirmation information of a certain signal detector, where the setting position of the signal detector is one side of the left front wheel, it may be determined that the tire pressure sensor carrying the identification mark in the confirmation information is located inside the left front wheel.
In step 305, the instrument panel or the terminal is instructed to correspondingly display the wheel position and the tire pressure information of the tire pressure sensor based on the identification of the tire pressure sensor and the wheel position corresponding to the tire pressure sensor.
Through being connected with the tire pressure sensor after the location, the tire pressure information that will the tire pressure sensor after the location monitoring shows through instructing panel board or terminal, and the driver of being convenient for observes, for example corresponds tire pressure information, the tire pressure information of left rear wheel of showing the front left wheel, etc..
In some embodiments, the controller may simultaneously acquire the tire pressure information monitored by each of the located tire pressure sensors, analyze the acquired tire pressure information, and send the analyzed tire pressure information to the indicating instrument panel or the terminal.
In some embodiments, in response to the indicated instrument panel receiving the parsed tire pressure information, the driver may view the information of the wheels through the indicated instrument panel during driving.
In some embodiments, in response to the terminal receiving the parsed tire pressure information, the driver may query the tire pressure information through the application.
In some embodiments, in response to a failure to continuously receive the tire pressure sensor acknowledgement information transmitted by the at least one signal detector within the first preset time period, the detection is performed again after the third preset time period, and in response to a failure to continuously receive the tire pressure sensor acknowledgement information transmitted by the at least one signal detector within the first preset time period, the failure information is transmitted to the indicating instrument panel or the terminal.
Optionally, the third preset time period may be 60 seconds.
Optionally, in response to the transmission failure information, the instrument panel or the application software is instructed to correspondingly display the "signal detector failure".
Therefore, according to the positioning method of the tire pressure sensor provided by the embodiment of the application, when the controller of the vehicle acquires the tire pressure sensor confirmation information sent by the at least one signal detector, the presence of the tire pressure sensor can be determined; on the basis of determining that the tire pressure sensor exists, the position of a wheel corresponding to the tire pressure sensor is determined according to the position information of the signal detector and the identification mark of the tire pressure sensor in the tire pressure sensor confirmation information, namely, the positioning of the tire pressure sensor is realized, and finally, according to the position of the wheel corresponding to the tire pressure sensor, the tire pressure information detected by the tire pressure sensor can be correspondingly displayed through an indicating instrument panel or a mobile phone application program. Therefore, the positioning method of the tire pressure sensor provided by the embodiment of the application can realize automatic positioning of the tire pressure sensor, replaces the existing manual operation mode, and is simple and convenient to operate.
Fig. 4 is a flowchart illustrating another tire pressure sensor locating method according to an exemplary embodiment. The detection range of each signal detector in this exemplary embodiment covers only the wheels on its adjacent sides. Taking a four-wheel automobile as an example, the four-wheel automobile may include four signal detectors, the four signal detectors are respectively a bluetooth module and three bluetooth antennas, as shown in fig. 7, wherein a detection range of the bluetooth module located between the left front wheel and the right front wheel only covers a sensing area 4 where the left front wheel and the right front wheel are located, a detection range of the bluetooth antenna 1 located between the left front wheel and the left rear wheel only covers the sensing area 4 where the left front wheel and the left rear wheel are located, a detection range of the bluetooth antenna 2 located between the right front wheel and the right rear wheel only covers a sensing area 2 where the right front wheel and the right rear wheel are located, and a detection range of the bluetooth antenna 3 located between the left rear wheel and the right rear wheel only covers a sensing area 3 where the left rear wheel and the right rear wheel are located.
As shown in fig. 4, the positioning method of the tire pressure sensor is used in a controller of a target vehicle, and is automatically performed when the vehicle is powered on, and the embodiment includes the following steps.
In step 401, the tire pressure sensor acknowledgement information sent by the at least two signal detectors is continuously received within a second preset time period, and it is determined that the tire pressure sensor acknowledgement information sent by the at least two signal detectors is obtained.
By continuously receiving the tire pressure sensor confirmation information transmitted by the at least one signal detector for the first preset time period, the stability of the signal transmitted by the signal detector may be ensured to better confirm that the target vehicle has at least one tire pressure sensor, wherein each signal detector detects two tire pressure sensors.
Before each tire pressure sensor is connected with the controller, signals carrying identification marks are continuously transmitted at a fixed frequency, the signals transmitted by the tire pressure sensors are detected by the signal detectors in real time, and the signal sensors immediately transmit confirmation messages to the controller in response to the signals of the tire pressure sensors detected by the signal detectors; and responding to the at least two signal detectors to continuously receive the signal carrying the identification mark in the second preset time period, namely, the at least two signal detectors continuously send confirmation information in the second preset time period, which indicates that the signal of the tire pressure sensor stably exists on the target vehicle, namely, confirming that the target vehicle has the tire pressure sensor with the identification mark, and sending the confirmation information to the controller.
Optionally, the second preset time period may be at least 10 seconds.
In step 402, it is determined whether there are two adjacent signal detectors each transmitting the tire pressure sensor acknowledgement information, based on the tire pressure sensor acknowledgement information transmitted by the at least two signal detectors.
It may be determined whether the target vehicle has two adjacent signal detectors each transmitting the tire pressure sensor confirmation information, based on the tire pressure sensor confirmation information transmitted by the at least two signal detectors. In response to the fact that the two adjacent signal detectors both send tire pressure sensor confirmation information, determining that the target vehicle has a tire pressure sensor to be positioned; otherwise, the target vehicle does not have a tire pressure sensor to be positioned.
The tire pressure sensor confirmation information comprises the identification mark of the tire pressure sensor, and the tire pressure sensor carrying the identification mark can be determined to be located on the target vehicle through the identification mark of the tire pressure sensor.
In step 403, in response to the presence of two adjacent signal detectors both sending tire pressure sensor acknowledgement information, it is determined that a tire pressure sensor to be positioned is present.
Because each signal detector detects two tire pressure sensors, the tire pressure sensor to be positioned cannot be determined according to one signal detector, but the tire pressure sensor to be positioned is determined simultaneously through two adjacent signal detectors. In response to the presence of two adjacent signal detectors both transmitting tire pressure sensor confirmation information, it may be determined that the target vehicle has a tire pressure sensor to be located.
For example, referring to fig. 7, if the signal detectors located between the front left wheel and the front right wheel and the signal detectors located between the front left wheel and the rear left wheel both transmit the tire pressure sensor identification information, and the tire pressure sensor identification information transmitted by the two signal detectors includes the same identification mark, it can be determined that the tire pressure sensor having the identification mark is the tire pressure sensor to be located in the target vehicle.
In step 404, based on that the two adjacent signal detectors both transmit the tire pressure sensor confirmation information, the wheel position corresponding to the tire pressure sensor to be positioned is determined.
Because the tire pressure sensor confirmation information comprises the identification mark of the tire pressure sensor, and each signal detector has corresponding setting position information, the wheel position corresponding to the tire pressure sensor to be positioned can be determined by combining the identification mark of the tire pressure sensor and the setting position information of two adjacent signal detectors which detect the tire pressure sensor.
It is to be understood that each signal detector has set position information indicative of its set position, for example, between the front left wheel and the rear left wheel.
Optionally, the number of the tire pressure sensors to be positioned may be determined according to the detected tire pressure sensor confirmation information sent by the two adjacent signal detectors, which is not specifically limited herein.
