S1. When the side-view radar module detects that the vehicle is coming from the side, the side-view radar module sends a corresponding arrival signal to the reminder module according to the position of the side-coming vehicle, and sends a first control signal to the tire pressure monitoring module.

The side-view radar module can be used to detect whether the side of the user's vehicle is coming. When the side of the vehicle comes, the side-view radar module can send a signal to the reminder module. When the user's vehicle comes from a different side, the side-view radar module Different vehicle arrival signals can be sent, and at the same time when the vehicle arrival signal is sent, a first control signal can also be sent to the tire pressure monitoring module, so that the tire pressure monitoring module monitors the tire pressure of the tire.

S2. When the reminder module receives the vehicle arrival signal, the reminder module performs a reminder according to the received vehicle arrival signal.

When the tire pressure monitoring module receives the control signal, it indicates that the user's vehicle has come around, and the vehicle may turn. During the steering process, when the tire pressure of the vehicle is too high or too low, it is easy to produce a vehicle. The possibility of failure, and then the possibility of a safety accident.

Therefore, before the vehicle may turn, and during the vehicle steering process, that is, when the tire pressure monitoring module receives the control signal and for a period of time thereafter, the tire pressure monitoring module monitors the tire pressure of the tire and sends the monitoring result to the Reminder module.

S5. The reminding module reminds according to the received tire pressure signal.

The reminder module can display the monitoring when receiving the monitoring result sent by the tire pressure monitoring module, so that the user can know the current state of the tire pressure.

In this embodiment, through the setting of the side-view radar module, the system can analyze and know that the vehicle may turn. Therefore, before turning, the function of monitoring the tire pressure of the tire is realized through the setting of the tire pressure monitoring module. Judge whether the tire pressure of the tire is within the normal range, to ensure that the tire pressure of the tire is within the normal range, and the monitoring result is more accurate.

During the driving process of the vehicle, there is no need to monitor whether the tire pressure is normal in real time. It is only necessary to monitor the tire pressure before and after the vehicle turns to realize the tire pressure monitoring and increase the service life of the tire pressure monitor. And the safety performance of the vehicle before turning is increased, and the reliability of the vehicle turning is increased.

S12. The side-view radar module analyzes the maintenance time of the vehicle coming from the side.

S13. When the side-view radar module analyzes that the maintenance time of the vehicle coming from the side is greater than a preset maintenance time, the side-view radar module sends a first control signal to the tire pressure monitoring module.

When the side-view radar module detects that the side of the vehicle is coming or the vehicle is facing a meeting, the remaining vehicles are within the monitoring range of the side-view radar for a short period of time. Through the maintenance time monitoring, it is convenient for the side-view radar module to analyze and obtain the side Whether the incoming vehicle needs the user's vehicle to turn. When the incoming vehicle on the side of the user directly exceeds the user's vehicle, the user's vehicle does not need to change lanes. Therefore, the vehicle does not need to perform a steering action and the vehicle does not need to monitor tire pressure.

When the vehicle on the rear side needs to overtake, but due to the interference of the user's vehicle, that is, when the user needs to turn, the side-view radar module can always detect the oncoming vehicle on the side, and the oncoming vehicle on the side can always be located on the rear side of the vehicle. Waiting for the user's steering, therefore, after the preset maintenance time, the vehicle can know that the user is about to turn, and the tire pressure monitoring module starts to monitor the tire pressure of the tire, so that the vehicle can safely perform the steering action.

Specifically, in this embodiment, the preset maintenance time can be selected from 5s to 20s, and can be changed according to the user's vehicle model and the user's needs.

According to yet another embodiment provided by the present invention, as shown in FIG. 4, a method for reminding a tire pressure and a side-view radar includes:

S1. When the side-view radar module detects that the vehicle is coming from the side, the side-view radar module sends a corresponding arrival signal to the reminder module according to the position of the side-coming vehicle and sends a first control signal to the tire pressure monitoring module.

S21. When the reminder module receives the arrival signal, the reminder module controls the corresponding side-view display screen to light according to the received arrival signal.

By setting the side view display screen, the user can continue to observe the reminder signal of the side view coming car, and can also automatically ignore the reminder when the user reminds, reducing the influence of the side view display screen on the user and reducing the side view The influence of the display screen on the user's driving process is conducive to the user's safe driving.

Preferably, S21 specifically includes:

S211. When the reminder module receives the arrival signal, the reminder module controls the corresponding side-view display screen to blink and light according to the received arrival signal.

According to yet another embodiment provided by the present invention, as shown in FIGS. 1 and 5, a method for reminding a tire pressure and a side-view radar includes:

S41. When the tire pressure monitoring module receives a control signal, the tire pressure monitoring module acquires the tire pressure of each tire of the vehicle at a first preset frequency.

S42. The tire pressure monitoring module analyzes whether all tire pressures obtained for each tire are within a first preset range.

S43. When all tire pressures of the tire are within the first preset range, the tire pressure monitoring module sends a normal tire pressure signal to the reminder module.

S44. When it is analyzed that there is a tire pressure outside the first preset range, a tire corresponding to the tire pressure outside the first preset range is taken as an abnormal tire.

S45. The tire pressure monitoring module sends an abnormal tire pressure signal corresponding to the abnormal tire to the reminder module.

When the tire pressure monitoring module receives the control signal, it indicates that the user is about to perform a steering action, and the vehicle starts to monitor the tire pressure of the tire. The tire pressure of each tire of the vehicle is obtained at the first preset frequency. The first preset frequency can be based on the user's Change it as needed. Specifically, the first preset frequency can be selected from 5s to 10s each time, and can be changed according to the needs of the user.

The first preset frequency in the current state is larger and much larger than the normal state of the tire pressure monitor during normal use. The tire pressure monitor can obtain the tire pressure of the tire multiple times in a short time to obtain a stable and reliable Tire pressure.

The tire pressure monitoring module can determine whether the tire pressure of the tire is within the usable tire pressure range during driving and steering, and the first preset range is the tire pressure range that the tire can run. Specifically, for example, for the standard type Tires, the first preset range is 2.0bar to 2.8bar, users can change the first preset tire pressure range according to different seasons and different tire types; when the tire pressure is outside the first preset range At this time, the tire is difficult to use normally, and it is easy to cause failure, which may lead to a safety accident.

Through the setting of the first preset range, it is convenient for the user to know whether there is a possibility that the tire in the current state has a failure during driving and steering, which increases the safety performance of the vehicle during driving.

When all tire pressures are monitored within the first preset range, it indicates that the tire has a low probability of being damaged in the normal form, so the normal tire pressure signal is sent to the reminder module, and there are multiple tires in use The tire pressure monitoring module can send a corresponding number of normal tire pressure signals to the reminder module.

When the tire pressure monitoring module detects that the tire pressure of a certain tire is outside the first preset range during driving, it means that the tire pressure in the current state is based on the limit state. When the user is driving normally When encountering the above situation again in the process, it is easy to cause failure. Therefore, the tire pressure monitoring module needs to mark the tire as an abnormal tire, and send the abnormal tire pressure signal corresponding to the abnormal tire to the reminder module, so that the user can know the existence of the basis The tire is in an unsafe state, which is convenient for users to improve the tire pressure of the tire as soon as possible, reducing the possibility of failure.

According to another embodiment provided by the present invention, as shown in FIGS. 1, 5 and 6, a method for reminding tire pressure and side-view radar includes:

S1. When the side-view radar module detects that the vehicle is coming from the side, the side-view radar module sends a corresponding arrival signal to the reminder module according to the position of the side-coming vehicle and sends the first control signal to the tire pressure monitoring module.

S431. When all tire pressures of the tires are within the first preset range, the tire pressure monitoring module analyzes whether all tire pressures obtained for each tire are within the second preset range.

S432. When all tire pressures of the tire are within the second preset range, the tire pressure monitoring module sends a normal tire pressure signal to the reminder module.

S433. When it is analyzed that there is a tire pressure outside the second preset range, a tire corresponding to the tire pressure outside the second preset range is used as a worn tire.

S434. Acquire the tire pressure frequency of the tire pressure monitoring module within a preset time period, the worn tire being outside the second preset range and the tire pressure frequency outside of the second preset range.

S435: Calculate the ratio of the tire pressure frequency outside the second preset range to the tire pressure frequency outside the second preset range.

S436. Analyze whether the tire pressure ratio is greater than a preset ratio.

S437. When the tire pressure ratio is less than or equal to a preset ratio, the tire pressure monitoring module sends a normal tire pressure signal to the reminder module.

S438. When the tire pressure ratio is greater than the preset ratio, the tire pressure monitoring module sends a loss signal corresponding to the lost tire to the reminder module.

When the tire pressure monitoring module detects that the tire pressure of all tires is within the first preset range, it indicates that the vehicle can run normally, and the possibility of failure during driving is low, and it is not easy to produce safety accidents; Whether the tire pressure of the tire is within the second preset range to determine whether the current tire pressure of the user can always be stable within the safe tire pressure range.

In this embodiment, for a standard tire, the first preset range is 2.3bar to 2.6bar, and the user can change the second preset tire pressure range according to different seasons and different tire types; probably the tire is in the second When it is within the preset range, the vehicle has a low probability of malfunctioning during normal driving and steering, and the user does not need to pay too much attention to the tire pressure of the tire.

When the tire pressure of the tire is within the first preset range, but the tire pressure is already outside the second preset range, the tire in the current state still has problems such as slight vibration, increased fuel consumption, or abnormal heating of the tire. The pressure monitoring module can obtain the tire pressure of the tire within a preset time period. The preset time period mainly refers to a period of time after the tire pressure monitoring module receives the control signal, and determines the tire by analyzing the tire pressure monitored during the period of time Whether it has been worn, or the tire pressure due to the absolute error is outside the second preset range.

Therefore, the total tire pressure frequency within the preset time period is used to calculate the tire pressure ratio between the tire pressure frequency outside the second preset range and the total tire pressure frequency, and to analyze whether the above tire pressure ratio is greater than the predetermined Set the ratio.

When the tire pressure ratio is greater than the set ratio, it indicates that the tire pressure continues to be outside the second preset range, the tire pressure has been lost, and the tire pressure monitoring module can mark the worn tire and send a loss signal; When the tire pressure ratio is less than or equal to the preset ratio, the tire pressure monitoring module can analyze that even if the tire pressure exceeds the second preset range, the tire is only a sudden change in tire pressure due to vibration and other external environmental factors. The tire pressure is still within the normal range, therefore, the tire pressure monitoring module can continue to send a normal tire pressure signal.

Therefore, the reminder module can remind in different ways when receiving different tire pressure signals, so that the user can clearly know the tire pressure of the tire.

Through the arrangement of the above-mentioned modules, the stability monitoring of the vehicle coming from the side of the vehicle and the data transmission with the tire pressure monitoring module 10 can be realized.

The reminder module 30 includes a tire pressure display screen 31 and a side-view display screen 32; the tire pressure display screen 31 is used to remind the tire pressure signal; the side-view display screen 32 is used to send a corresponding incoming signal Reminder; the side-view display screen 32 is set to two, and the side-view display screen 32 is provided on both sides of the tire pressure display screen 31.

By setting the side-view display screen 32 on both sides of the tire pressure display screen 31, the user can clearly understand whether the side of the user's vehicle comes to the vehicle on the technology of obtaining the tire pressure of the tire, which is convenient for the user to turn. The safety performance of users during driving.

Preferably, the reminder module 30 further includes a buzzer (not shown in the figure); the buzzer is used to emit a buzzer sound when receiving a car arrival signal. Through the setting of the buzzer, when the side-view radar module 20 detects that the vehicle is coming from the side, the buzzer can be used to remind the user, so that the user can perform the steering action in time, and can also conveniently remind the user to view the reminder module 30 It is convenient for the user to know the tire pressure of all tires, so that the vehicle can safely and reliably perform the steering action.

According to the improvement of the above embodiment, in this embodiment, the tire pressure display screen 31 and the side view display screen 32 are integrally formed. The integrated tire pressure display 31 and the side view display 32 facilitate the processing and production of the reminder module 30, and also facilitate the electrical connection of the tire pressure monitoring module 10 and the side view radar module 20 to the reminder module 30. The user simultaneously observes the tire pressure of the tire and the oncoming situation on the side of the user's vehicle.

When the side-view radar module 20 detects that the vehicle is coming from the side of the vehicle or the vehicle is facing a meeting, the remaining vehicles are within the monitoring range of the side-view radar for a short period of time. Through the maintenance time monitoring, the side-view radar module 20 analyzes Obtain whether the oncoming vehicle on the side requires the user's vehicle to turn. When the oncoming vehicle on the user's side directly exceeds the user's vehicle, the user's vehicle does not need to change lanes. Therefore, the vehicle does not need to turn and the vehicle does not need to monitor tire pressure. .

When the vehicle on the rear side needs to overtake, but when the user's vehicle has interference, that is, when the user needs to turn, the side-view radar module 20 can always be located on the rear side of the vehicle when it detects a side-on vehicle Waiting for the user's steering, therefore, after the preset maintenance time, the vehicle can know that the user is about to turn, and the tire pressure monitoring module 10 starts to monitor the tire pressure of the tire, so that the vehicle can safely perform the steering action.

When the tire pressure monitoring module 10 receives the control signal, it indicates that the user is about to perform a steering action, and the vehicle starts to monitor the tire pressure of the tires. The tire pressure of each tire of the vehicle is obtained at the first preset frequency. The first preset frequency can be selected from 5s / time to 10s each time, and can be changed according to the needs of the user.

The tire pressure monitoring module 10 can determine whether the tire pressure of the tire is within the usable tire pressure range during driving and steering, and the first preset range is the tire pressure range that the tire can run, specifically, for example, for the standard Type tires, the first preset range is 2.0bar to 2.8bar, users can change the first preset tire pressure range according to different seasons and different tire types; when the tire pressure is within the first preset range Outside, the tires are difficult to use normally, and are prone to cause failures, which may lead to safety accidents.

When all tire pressures are monitored within the first preset range, it indicates that the tire is in a normal form, and the probability of damage is small, so the normal tire pressure signal is sent to the reminder module 30, and there are multiple tires in use in the vehicle At this time, the tire pressure monitoring module 10 can send a corresponding number of normal tire pressure signals to the reminder module 30.

When the tire pressure monitoring module 10 detects that the tire pressure of a certain tire is outside the first preset range during driving, it indicates that the tire pressure in the current state is based on the limit state, when the user is in normal When the above situation is encountered again during driving, the possibility of failure is likely to occur. Therefore, the tire pressure monitoring module 10 needs to mark the tire as an abnormal tire and send an abnormal tire pressure signal corresponding to the abnormal tire to the reminder module 30, so that the user can easily obtain Knowing that there is a tire in an unsafe state, it is convenient for users to improve the tire pressure of the tire as soon as possible, reducing the possibility of failure.

When the tire pressure monitoring module 10 monitors that the tire pressures of all tires are within the first preset range, it indicates that the vehicle can run normally, and the possibility of failure during driving is low, and it is not easy to produce safety accidents; It is compared whether the tire pressure of the tire is within the second preset range to determine whether the current tire pressure of the user can always be stable within the safe tire pressure range.

When the tire pressure of the tire is within the first preset range, but the tire pressure is already outside the second preset range, the tire in the current state still has problems such as slight vibration, increased fuel consumption, or abnormal heating of the tire. The pressure monitoring module 10 can obtain the tire pressure within a preset period of time. The preset period mainly refers to a period of time after the tire pressure monitoring module 10 receives the control signal and analyzes the tire pressure monitored during the period It is determined whether the tire has been worn or the tire pressure due to the absolute error is outside the second preset range.

When the tire pressure ratio is greater than the set ratio, it indicates that the tire pressure continues to be outside the second preset range, the tire pressure has been lost, the tire pressure monitoring module 10 can mark the worn tire, and send a loss signal When the tire pressure ratio is less than or equal to the preset ratio, the tire pressure monitoring module 10 can analyze that even if there is a tire pressure that exceeds the second preset range, the tire is only due to vibration and other external environmental factors. Suddenly, the tire pressure is still within the normal range. Therefore, the tire pressure monitoring module 10 can continue to send a normal tire pressure signal.

Therefore, when receiving different tire pressure signals, the reminder module 30 can remind in different ways, so that the user can clearly know the tire pressure of the tire.

It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principles of the present invention, several improvements and retouches can be made. It should be regarded as the protection scope of the present invention.
