Description

Technical Field

[0001] The invention relates to a parameter adjustment method, and more particularly to a method for adjusting parameters of a tire pressure alarm of a vehicle tire. Background Art

[0002] The tire pressure monitoring system is an extremely important system on current vehicles. By monitoring the tire pressure, it can effectively understand the current tire pressure status of the car and make timely reminders to remind the driver to replenish the tire pressure in time to avoid problems caused by insufficient or excessive tire pressure during vehicle driving.

[0003] Existing tire pressure monitoring systems mainly use two methods: indirect and direct. The direct method has many advantages over the indirect method, so the direct method is more commonly used in the existing technology. The main principle of the direct method is to use the car main control board as the upper computer, and then set tire pressure monitoring sensors in the four tires one by one. The two are wirelessly transmitted to achieve the effect of monitoring tire pressure data. The owner can set the tire pressure alarm value range and temperature alarm value according to the model, driving habits, and geographical location. However, the existing setting method of tire pressure alarm parameters is mainly through professional tire pressure programming equipment. This makes the setting process more complicated for ordinary car owners, and the data is directly input during the setting process. The owner does not understand the meaning of the data very well, so it is impossible to simply and effectively set the tire pressure alarm parameters. Summary of the invention

[0027] Figure 3This is a schematic diagram of the structure of embodiment 2 of the bump condition sensor. DETAILED DESCRIPTION

[0028] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0029] Reference Figure 1 As shown, a method for adjusting tire pressure alarm parameters of a vehicle in this embodiment includes the following steps:

[0030] Step 1: construct a database server, and store a data set in which external conditions and adjustment values ​​correspond one to one in the database server;

[0031] Step 2: input the initial tire pressure alarm threshold as the starting parameter;

[0032] Step 3: Displaying an external condition selection button on the user interaction interface for the user to select an external condition;

[0033] Step 4: After the user selects the external conditions, the system communicates with the database server, retrieves the adjustment values ​​corresponding to the external conditions one by one, and adjusts the initial parameters according to the adjustment values ​​to complete the programming of the tire pressure monitoring sensor. The external conditions in the database server in step 1 include road conditions, external weather conditions, and outdoor temperature conditions. The adjustment values ​​in step 4 are calculated by the following formula:

[0034] Adjustment value = weight coefficient * road condition value + weight coefficient * weather condition value + weight coefficient * outdoor temperature condition value. In the process of using the method of this embodiment, you only need to execute steps one to four in sequence. Through the execution of steps one and two, the database can be built and the initial parameters can be set. Then, when the user needs programming, through the execution of steps three and four, the external condition button can be selected to simply and quickly modify the initial parameters, thereby realizing the programming of the tire pressure monitoring sensor.

[0035] As an improved specific implementation method, the external conditions in the database server in step 1 include road conditions, external weather conditions and outdoor temperature conditions, and the adjustment value in step 4 is calculated by the following formula:

[0036] Adjustment value = weight coefficient * road condition value + weight coefficient * weather condition value + weight coefficient * outdoor temperature value. In the process of existing vehicle driving, the situation that has a greater impact on tire pressure is mainly road conditions. According to the different flatness of the road, the required range of tire pressure is also different. For example, when the road is relatively flat, the pressure applied by the vehicle to the tire does not change much overall, and the threshold range of tire pressure can be set larger. When the tire pressure is high or low, the probability of a tire blowout is not very high. When the road flatness is low, various pressure changes will be caused to the tire during the vehicle driving. In this way, it is easy to have a tire blowout when the tire pressure is high or low. Therefore, the tire pressure threshold range at this time needs to be sharply reduced to avoid the above situation. In addition, the outdoor The temperature and weather conditions will have a certain impact. For example, when the external temperature is high, the tire temperature will be high during driving, which will cause the air inside the tire to expand due to heat. At this time, if the tire pressure is high, it is easy to have a tire blowout. When it is rainy outside, the rain on the ground will cause the tire surface temperature to drop, and sufficient pressure is required to drain the water flow during driving. Therefore, if the tire pressure is low at this time, water floating will easily occur, causing the vehicle to slip. In this way, the above method can effectively adjust the threshold range of the vehicle's tire pressure alarm according to the current external conditions to ensure that the driver can drive with a safe tire pressure. Since the road flatness has the greatest impact and the temperature has the smallest impact, the weight coefficients in this embodiment can be set to 0.6, 0.3, and 0.1.

[0037] As an improved specific implementation, the step three also includes an automatic selection step, which is as follows:

[0038] Step 31: installing a bump condition sensor, a rain sensor and a temperature sensor on the vehicle to detect road conditions, weather conditions and temperature;

[0039] Step 32, according to the road conditions, weather conditions and temperature obtained in step 31, the adjustment values ​​in the database server are retrieved one by one to complete the external condition selection. Through the settings of the above steps, the current programming content of the tire pressure monitoring sensor can be effectively adjusted in real time during driving. It can be combined with patent number 2020116212316, entitled "A vehicle tire automatic inflation and deflation device" to achieve the effect of real-time adjustment of the vehicle tire pressure, which greatly increases the automation. The bump condition sensor in this embodiment can be integrated into the programming system, and the rain sensor and temperature sensor can use the vehicle's own conditions. As a specific implementation method of the improvement, Figure 1As shown, the bump sensor includes a vibration block 2 and a long strip-shaped sensor housing 1, wherein the sensor housing 1 is used to be vertically mounted on an external vehicle, wherein the upper and lower sides of the vibration block 2 are fixedly connected to the upper and lower ends of the sensor housing 1 through springs, and a plurality of induction coils are coaxially arranged in the sensor housing 1, wherein the vibration block 2 is made of magnetic material, and an output plate is fixed to the upper end of the sensor housing 1, and a plurality of induction coils are connected to the output plate through wires, respectively. By setting the above structure, the distance of the vibrator can be effectively utilized to realize the detection of road bumps.

[0040] As an improved specific implementation method, the specific steps of the bump condition sensor detecting the road condition are as follows:

[0041] Step 21: number the induction coils in sequence from the middle to both ends, with the two groups of numbers corresponding to each other;

[0042] Step 22, setting voltage detection circuits corresponding to the induction coils in the output board, and numbering these voltage detection circuits, taking the time period during which the voltage detection circuits corresponding to the two groups of numbers can detect voltage as a vibration period, and the average voltage in one vibration period as a vibration amplitude;

[0043] Step 23: Calculate the road bump index according to the following formula:

[0044] Road bump index = number of cycles * average vibration amplitude;

[0045] Step 24, input the road bump index obtained in step 23 into the database server to obtain the road condition. Through the setting of the above steps, the road bump condition can be effectively detected.

[0046] As a specific implementation of the improvement, the vibration block 2 includes a vibration base 21 and a vibration pendulum 22, the vibration pendulum 22 is made of magnetic material, the vibration base 21 is connected to the upper and lower ends of the sensor housing 1 through a spring, the middle part of the vibration pendulum 22 is hinged on the vibration base 21, and counterweights 221 are provided at both ends. The counterweights 221 keep the vibration pendulum 22 in a horizontal state. When a vehicle is driving on a bumpy road, sometimes the body of the vehicle does not vibrate up and down, but because of the contact between the tire and the external ground, the body of the vehicle will swing at the center of the body. In order to ensure the accuracy of vibration detection, the bump condition sensor is generally installed at the center of the body. Therefore, through the setting of the above structure, when the body does not vibrate up and down, it can also swing with the body through the action of the vibration pendulum 22, so as to detect road bumps.

[0047] As an improved specific implementation method, a hinge groove 23 is provided on the upper side surface of the vibration base 21, and hinge holes 231 are provided on the groove walls on the front and rear sides of the hinge groove 23. Hinge columns 221 are fixed on the front and rear sides of the middle part of the vibration swing rod 22, and the hinge column 221 is rotatably arranged in the hinge hole 231. Locking grooves 232 are provided on the hole walls on the upper and lower sides of the hinge hole 231, and a locking pin is slidably connected in the locking groove 232. A locking hole is provided on the hinge column 221, and the locking pin is connected to the groove bottom of the locking groove 232 through an elastic component, and can slide in the locking groove 232 to slide into the locking hole or slide out of the locking hole. Through the arrangement of the above structure, the swing function of the vibration swing rod 22 can be effectively locked when the vehicle body vibrates up and down, thereby avoiding the problem of increased detection error due to the swing of the vibration swing rod 22 during up and down vibration.

[0048] As an improved specific implementation method, a plurality of hinge pillars are provided on the hole wall of the hinge hole 231, and the ends of the plurality of hinge pillars on the hole wall facing away from the hinge hole 231 form a circular space for accommodating the hinge column 221. The hinge pillars are all hollow and have through holes at their ends. The hinge pillars are filled with lubricating oil. Through the above-mentioned structural arrangement, the swinging of the vibration rocker 22 can be made smoother, and the lubricating oil can be effectively retained.

[0049] As another specific implementation method of the improvement, Figure 2 As shown, the bump sensor includes a shell 3 in the shape of an elongated strip and a sliding block 4 arranged in the shell 3, a plurality of induction coils are inserted in the shell wall of the shell 3, the shell 3 is filled with two liquids with different densities, a magnet is arranged on the sliding block 4, and the density of the sliding block 4 is between the two liquids. Through the arrangement of the above structure, since the overall density of the sliding block 4 is between the two liquids, the sliding block 4 will be between the two liquids when there is no external force, and the viscosity of the liquid in this embodiment cannot be too high, so that the buoyancy of the lower liquid and the gravity of the sliding block 4 itself are used to achieve the reset effect. Since liquid is used, the situation in which the spring fatigue causes difficulty in vibration in the above scheme will not occur, and the service life is more durable.

[0050] To sum up, the method of this embodiment can effectively build a database to set initial parameters through the settings of steps one to four. Then, when the user needs to modify the parameters, he only needs to select external conditions to simply and effectively program the tire pressure monitoring sensor.

[0051] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
