An information acquisition step of acquiring tire pressure data, tire position coordinates and vehicle information, wherein the vehicle information comprises vehicle position coordinates, vehicle steering wheel data, safety belt locking information, current vehicle speed information and KL15 state;
specifically, tire pressure data, tire position coordinates, and vehicle information are acquired, and judgment and processing are performed according to the magnitude and rate of change of tire pressure.
A tire monitoring step of performing tire monitoring on a vehicle according to the tire pressure data, the tire position data and the vehicle information, the tire monitoring including:
a park tire pressure monitor to send an alarm message when KL15 status is powered down and the tire pressure data is reduced to a specified empty tire pressure;
a vehicle parking tire position monitor to send an alarm message when a KL15 state is powered down and a coordinate difference between the tire position coordinates and the vehicle position coordinates is a specified interval;

the vehicle starts tire deviation monitoring, wherein the vehicle starts tire deviation monitoring is used for sending alarm information when the KL15 state is powered on and when the tire is deviated;
and the tire position self-learning judges the corresponding positions of the tire and the vehicle according to the tire position coordinates and the vehicle position coordinates.
Specifically, the use of vehicle parked tire pressure monitoring may result in slow tire air leakage if the vehicle nails after the vehicle is turned off, and may automatically alert when the tire pressure data is reduced to a specified empty tire pressure, such as 75% of the empty pressure. Meanwhile, the alarm information of the mobile phone APP of the vehicle owner can be pushed to be too low through the T-BOX, so that the vehicle owner can reasonably arrange the next-day travel, and the reserved time can be used for removing faults.
Specifically, the vehicle parked tire position monitoring application scenarios such as tire loss monitoring: after KL15 flameout, vehicle tire coordinates such as (X1, Y1, Z1), (X2, Y2, Z2), (X3, Y3, Z3), (X4, Y4, Z4) are obtained. If the coordinates of the vehicle tire or the coordinate difference between the vehicle tire and the position (X0, Y0, Z0) of the vehicle position coordinate is not obtained and is larger than a specified interval such as 1 meter (X0-X1/2/3/4>1 or Y0-Y1/2/3/4), judging that the tire position is abnormal, and sending alarm information through a T-BOX, and carrying out background pushing owner mobile phone APP alarm information 'tire position abnormality', so as to remind of the tire position abnormality. Meanwhile, the loudspeaker of the whole vehicle is controlled to sound for a certain time, such as 10 minutes, and meanwhile, the steering lamp twinkles to carry out audible and visual alarm for a certain time, such as 10 minutes, so as to deter.
Specifically, the abnormal tire pressure state includes the tire pressure being greater than a non-empty specified pressure when the vehicle is not fully loaded, the tire pressure being less than the specified empty tire pressure, the tire pressure change rate calculated from the tire pressure data being greater than a specified tire pressure change rate, and the tire pressure data being less than a specified minimum tire pressure.
When the vehicle is not fully loaded, the tire pressure is larger than the non-empty specified pressure, namely the tire pressure ratio is larger during running. The tire inflation pressure is typically greater than a threshold value, such as 3.0Bar, for protection of the tires from aging, for long-term transportation and storage of the vehicle when the vehicle is shipped. In practice, most vehicles do not run under full load, so that the tire pressure of more than 3.0Bar is high, the comfort is poor, and the tires are easy to wear. Whether the vehicle is fully loaded can be judged by whether the front and rear rows of safety belts are locked or not. If the vehicle is in a non-full load state and the received tire pressure is greater than 3.0Bar, the tire pressure controller informs an instrument or navigation through a gateway to carry out tire high pressure alarm prompt: reducing the tire pressure or lowering the tire pressure to the empty recommended value.
The tire pressure is less than the specified empty tire pressure, i.e., the tire pressure is less than the specified empty tire pressure. When the tire pressure is less than a specified value, such as 75% of the recommended empty pressure for the vehicle. At this time, an alarm prompt is sent, such as: the pressure is low, the tire is checked or inspected, and the tire pressure is replenished to the empty recommended value.
The tire pressure change rate calculated from the tire pressure data is greater than the specified tire pressure change rate, i.e., the tire pressure changes too fast. If the specified tire pressure change rate is >0.3 Bar/min, the rapid air leakage is judged. At this time, the push alarm prompts are as follows: please immediately stop checking the supplemental tire pressure and turn on the double flashing warning or turn-on warning light.
The tire pressure data is smaller than a specified minimum tire pressure, i.e., the tire pressure is too small. When the tire pressure is less than a specified tire pressure, such as 0.5Bar, the high-speed continuous running of the vehicle may cause a blowout due to a large increase in the frictional resistance of the tire and the ground. At this time, an alarm prompt is sent: and immediately stopping the vehicle to check the pressure of the supplementary tire, and simultaneously turning on a double-flashing warning or steering warning lamp to prompt the vehicle behind to avoid. At the same time, the environmental control module and buzzer alarms lasting for several seconds are turned on. At this time, vehicle control modules such as an electronic stability system (ESP) and an autopilot module control the vehicle to detect the surrounding environment and actively brake and slow down.
Specifically, the vehicle-initiated tire bias monitoring includes the steps of:
when the obtained steering wheel data are return data and the current vehicle speed information is larger than the appointed vehicle speed, obtaining and recording the tire position coordinates in the appointed time, and sending alarm information if the transverse axis value of the tire position coordinates changes relatively.
Further, when the KL15 state is power-on, if the current vehicle speed is greater than 20 KM/time, whether the steering wheel is aligned or not is judged by monitoring the data of the steering wheel of the vehicle such as the steering angle of the steering wheel. In the case of steering wheel alignment, the position coordinates X of the tire are obtained, for example, within a specified time, for example, within 10 minutes, and if the X coordinates are connected together to be a curve, that is, the tire track is a curve, the tire condition is judged to be abnormal. At this time, alarm information is sent, such as a meter or a navigation display: the vehicle is deviated, and the vehicle is inspected and four-wheel positioning is carried out.
Specifically, the tire position self-learning determination of the corresponding position of the tire and the vehicle includes the steps of:
if the abscissa of the tire position coordinate is greater than the abscissa of the vehicle position coordinate and the ordinate of the tire position coordinate is greater than the ordinate of the vehicle position coordinate, the tire is the right front wheel;
if the abscissa of the tire position coordinate is greater than the abscissa of the vehicle position coordinate and the ordinate of the tire position coordinate is less than the ordinate of the vehicle position coordinate, the tire is the right rear wheel;
if the abscissa of the tire position coordinate is smaller than the abscissa of the vehicle position coordinate and the ordinate of the tire position coordinate is larger than the ordinate of the vehicle position coordinate, the tire is the left front wheel;
if the abscissa of the tire position coordinate is smaller than the abscissa of the vehicle position coordinate and the ordinate of the tire position coordinate is smaller than the ordinate of the vehicle position coordinate, the tire is the left rear wheel.
Further, since the tire position coordinates and the vehicle position coordinates are acquired, and the positions of the left front, right front, left rear and right rear relative to the navigation module of the whole vehicle are fixed, the position information such as (X0, Y0, Z0) of the navigation of the whole vehicle is acquired through the CAN bus, and the position information (X1, Y1, Z1), (X2, Y2, Z2), (X3, Y3, Z3), (X4, Y4, Z4) of the four tires is acquired, and the left and right, that is, the left tire electronic module X0-X1/2/3/4>0, and the right tire electronic module X0-X1/2/3/4<0 are judged by comparing the X coordinates; the front and rear, namely left tire electronics module Y0-Y1/2/3/4>0 and right tire electronics module Y0-Y1/2/3/4<0 are determined by comparing the Y coordinates.
In addition, the tire pressure navigation sensor for monitoring the tire pressure by using the control method for detecting the tire of the navigation module, which is preferred in the embodiment of the invention, can also obtain the coordinate position and the unique ID serial number through the self-learning of the tire position, so that the correct position can be set in the setting, such as: front left, front right, rear left. The tire pressure at which position can be known from the pressure and ID of the tire pressure navigation sensor. If the tire pressure navigation sensor is damaged in the after-sales use, a new tire pressure navigation sensor is replaced after the after-sales use. When the tire pressure controller receives no tire pressure information of the original position coordinates and the ID, but receives a new pressure of the same position coordinates but different IDs, the tire pressure controller automatically deletes the ID of the tire electronic module at the original position and replaces the ID with the ID of the new tire electronic module.
