[0031] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0033] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0034] It should also be pointed out that the terms "first\second\third" involved in the embodiments of the present application are only used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of the present application described here can be implemented in an order other than that illustrated or described here.

[0035] The present application provides a vehicle computer temperature control method. After the vehicle computer controller is powered on, the vehicle computer fan assembly speed is automatically adjusted based on the shell temperature of the thermoelectric cooling element in the vehicle computer and the volume parameter of the power amplifier module of the vehicle computer, and the fan assembly speed is intelligently matched to the appropriate fan assembly speed.

[0036] The present application provides a vehicle temperature control method, which is applied to a vehicle temperature control device. Figure 1 As shown, the method comprises the following steps:

[0037] Step 101: The controller of the vehicle computer is powered on to obtain the shell temperature of the thermoelectric cooling element in the vehicle computer.

[0038] In the embodiment of the present application, the controller includes but is not limited to a microcontroller (MCU), which has the characteristics of fast startup speed, low cost and low power consumption. The MCU can perform management / control functions on hardware devices (such as fan components). The vehicle temperature control device includes a controller and a processor, wherein the controller can control the power-on startup of the processor.

[0039] Here, the housing temperature of the thermoelectric cooling element in the vehicle machine may change under the influence of the ambient temperature in the vehicle and / or under the influence of the operation of the processor.

[0040] In the embodiments of the present application, the thermoelectric cooling element includes but is not limited to a semiconductor refrigerator (Thermo Electric Cooler, TEC). The shell temperature of the thermoelectric cooling element includes but is not limited to the shell temperature Tt of the TEC. TEC is made using the Peltier effect of semiconductor materials; it can be understood that the Peltier effect refers to the phenomenon that when a direct current passes through a couple composed of two semiconductor materials, one end absorbs heat and the other end releases heat. When current flows through the TEC, heat is transferred from one side of the thermoelectric cooling element to the other side, causing the thermoelectric cooling element to have a "hot" side and a "cold" side. The processor of the present application is attached to the heat-absorbing end of the thermoelectric cooling element. When the temperature of the processor is high, the thermoelectric cooling element operates to cool the processor. TEC cooling, and the cooling rate, is determined by the size of the current passing through it. When the ambient temperature is low, the processor can also be heated by electric heating.

[0041] In practical applications, if the required cooling or heating capacity is large, a multi-stage semiconductor refrigerator can be used. For equipment that runs all year round, increasing the logarithm of the cooling elements can obtain a higher cooling coefficient.

[0042] The execution subject of this embodiment is a vehicle temperature control device, which has functions such as data processing, data communication, and program operation. Generally, the operation of each component in the vehicle temperature control device can be driven by a core controller, so the execution subject of this embodiment can also be a controller in the vehicle temperature control device.

[0043] In the embodiment of the present application, the vehicle temperature control device may include, for example, a vehicle-mounted centralized control device, a smart phone, a tablet computer, a laptop computer, a PDA, a personal digital assistant (PDA), etc., and the embodiment of the present application does not make specific limitations.

[0044] Step 102: If the housing temperature satisfies the first temperature range, obtain the volume parameter of the power amplifier module of the vehicle computer.

[0045] In the embodiment of the present application, the power amplifier module of the vehicle computer is used to play sound signals. During the operation of the power amplifier module, it is specifically used to amplify the sound signals and drive the speakers to improve the power and sound quality of the audio output.

[0046] It can be understood that the power amplifier module includes a built-in power amplifier module and / or an external power amplifier module, the built-in power amplifier module refers to the power amplifier module integrated in the vehicle computer, and the external power amplifier module is an independent module installed outside the vehicle computer. The volume parameters of the power amplifier module include but are not limited to the number of volume grids. It should be noted that when the power amplifier module is not turned on, the volume parameter obtained is a specific value, for example, the number of volume grids is 0.

[0047] Exemplarily, the first temperature range is (35° C., 70° C.), and the first temperature range can be set according to actual needs, and this application does not make any specific limitations on this.

[0048] Step 103: Based on the housing temperature and volume parameters, adjust the speed of the fan assembly of the vehicle computer.

[0049] In the embodiment of the present application, the fan assembly includes but is not limited to a fan, which is used for heat dissipation. Here, heat dissipation includes but is not limited to heat dissipation of the environment inside the vehicle and / or heat dissipation of the processor.

[0050] That is to say, when the controller of the vehicle computer is powered on, the present application can obtain the shell temperature of the thermoelectric cooling element in the vehicle computer. Furthermore, when the shell temperature meets the first temperature range, it triggers the operation of adjusting the fan assembly speed based on the shell temperature and / or volume parameters, thereby intelligently matching the appropriate fan assembly speed.

[0051] It should be noted that the control method of the present application for adjusting the speed of the fan assembly of the vehicle computer based on the shell temperature and / or volume parameters can be applied after the controller of the vehicle computer is powered on, before the processor is started, during the processor startup, or at any stage after the processor is started, to achieve flexible control of the speed of the fan assembly of the vehicle computer and achieve noise reduction effect in various scenarios.

[0052] The present application provides a vehicle computer temperature control method, the method comprising: powering on a vehicle computer controller to obtain a shell temperature of a thermoelectric cooling element in the vehicle computer; if the shell temperature satisfies a first temperature range, obtaining a volume parameter of an amplifier module of the vehicle computer; adjusting a rotation speed of a fan assembly of the vehicle computer based on the shell temperature and the volume parameter; solving the problem in the related art that when heat dissipation is required, the fan assembly is controlled to operate at a preset fixed speed at a high speed, resulting in excessive noise; the present application automatically adjusts the rotation speed of the fan assembly of the vehicle computer in combination with the shell temperature and the volume parameter, and intelligently matches the rotation speed of the fan assembly to a suitable speed, thereby realizing not only temperature regulation of the vehicle computer, but also flexible adjustment of the rotation speed of the fan assembly to avoid excessive noise caused by a high-speed fixed speed.

[0053] In some embodiments of the present application, after step 103 adjusts the speed of the fan assembly of the vehicle based on the housing temperature and the volume parameter, the following steps may be performed:

[0054] First, the case temperature of the thermoelectric cooling element is obtained.

[0055] Here, the shell temperature is used to represent the temperature of the processor of the vehicle computer, and the heat absorption end of the thermoelectric cooling element is in contact with the processor; wherein, when the thermoelectric cooling element is TEC, the heat absorption end of the TEC is the cold side on the TEC.

[0056] Secondly, if the housing temperature meets the second temperature range, the processor of the vehicle computer is powered on to run the application program of the vehicle computer system.

[0057] In the embodiment of the present application, the processor includes but is not limited to a microprocessor (Micro Processor Unit, MPU), and the MPU has characteristics such as high performance. The MPU can run relatively complex programs and tasks with large computational load.

[0058] Exemplarily, the second temperature range is (-15°C, 80°C). The second temperature range can be set according to actual needs, and this application does not make any specific limitations on this.

[0059] In a feasible vehicle temperature control scenario, exemplarily, the thermoelectric cooling element is TEC, the controller is MCU, and the processor is MPU. In the vehicle temperature control scenario after the MCU is powered on and before the MPU is started, at this time, the volume parameter of the power amplifier module obtained is 0; in this scenario, if the TEC shell temperature is not within the first temperature range, for example, the TEC shell temperature is greater than 80°C, it indicates that it does not meet the operating temperature range for MPU startup, and temperature control is performed in time to avoid the situation where the MPU is directly started in a non-operating temperature range and causes damage to the vehicle. The fan speed is adjusted in combination with the TEC shell temperature. In this way, after temperature reduction control, when the TEC shell temperature meets the second temperature range, for example, when the TEC shell temperature is less than 80°C, the MPU is controlled to power on and start to run the application of the vehicle system. In this way, damage to the MPU is effectively avoided.

[0060] In some embodiments of the present application, step 103 adjusts the speed of the fan assembly of the vehicle based on the housing temperature and the volume parameter, which can be achieved by the following steps:

[0061] The fan assembly speed of the vehicle computer is adjusted based on the housing temperature, volume parameters and the preset adjustment coefficient corresponding to the power amplifier module.

[0062] Among them, when the power amplifier module is an external power amplifier module, the corresponding preset adjustment coefficient is in a first numerical range, and when the power amplifier module is a built-in power amplifier module, the corresponding preset adjustment coefficient is in a second numerical range, and the value of the first numerical range is smaller than the value of the second numerical range.

[0063] Exemplarily, when the power amplifier module is a built-in power amplifier module, the corresponding preset adjustment coefficient is expressed as N, and when the power amplifier module is an external power amplifier module, the corresponding preset adjustment coefficient is expressed as K. Based on the housing temperature, the volume parameter and the preset adjustment coefficient corresponding to the power amplifier module, the speed of the fan assembly of the vehicle machine (for example, the fan speed F) is adjusted, which can be achieved by the following formula (1) or formula (2):

[0064] When the vehicle computer uses a built-in amplifier module, the fan speed F can be calculated using the following formula (1):

[0065] If 35℃<Tt<70℃, F=N*20LOG[L*(S+1)] Formula (1)

[0066] When the vehicle computer uses an external power amplifier module, the fan speed F can be calculated using the following formula (2):

[0067] If 35℃<Tt<70℃, F=K*20LOG[L*(S+1)] Formula (2)

[0068] Among them, S is the volume level; for example, N is in the second numerical range and can be 80, of course, the value of N can be changed according to the actual needs of the project; K is in the first numerical range and can be 50, of course, the value of K can be changed according to the actual needs of the project; L is the target coefficient, which can be 2500 and can be adjusted according to the actual heat dissipation needs. In this way, whether the car machine uses an external power amplifier module or a built-in power amplifier module, the temperature and volume level can be combined to achieve the effect of reducing fan noise.

[0069] It should be noted that when Tt≥80℃, the controller will perform a shutdown operation to improve the safety of the controller and extend the service life of the controller.

[0070] In some embodiments of the present application, Figure 1 In step 101, the controller of the vehicle computer is powered on, and after obtaining the shell temperature of the thermoelectric cooling element in the vehicle computer, the following steps may also be performed: Figure 2 Steps shown:

[0071] Step 104: If the housing temperature satisfies the third temperature range, adjust the speed of the fan assembly of the vehicle computer to the upper speed threshold.

[0072] Exemplarily, the third temperature range is greater than or equal to 70°C. The third temperature range can be set according to actual needs, and this application does not specifically limit this. That is to say, when Tt≥70°C, whether the vehicle computer uses a built-in amplifier or an external amplifier, the fan speed F=the upper speed threshold (Mmax), and the main purpose at this time is to reduce the temperature.

[0073] In some embodiments of the present application, the shell temperature of the thermoelectric cooling element in the vehicle can be obtained in step 101 by Figure 3 The steps shown achieve:

[0074] Step 1011, obtaining the thermistor value of the thermoelectric cooling element;

[0075] Step 1012: Determine the housing temperature corresponding to the thermistor value based on a preset corresponding relationship.

[0076] In the embodiment of the present application, the thermistor value of the thermoelectric cooling element has a one-to-one correspondence with Tt. In practical applications, the Tt corresponding to the thermistor value can also be quickly found based on a table lookup method.

[0077] The thermistor value of the thermoelectric cooling element can be obtained by Figure 4 The steps shown achieve:

[0078] Step 10111, obtaining a pull-up resistance value of a pull-up resistor connected in series with a thermistor, and a pull-up voltage value inputted at one end of the pull-up resistor;

[0079] Wherein, the pull-up voltage value is an adjustable voltage value and / or the pull-up resistance value is an adjustable resistance value;

[0080] Step 10112, obtaining the input voltage of thermistor temperature measurement;

[0081] Step 10113: Determine the thermistor value based on the input voltage, the pull-up resistance value, and the pull-up voltage value.

[0082] In the embodiment of the present application, the pull-up voltage value is an adjustable voltage value, so that the pull-up voltage value can be variable, for example, 3.3 or 5V. In this way, different power supplies can be connected to accurately calibrate the thermistor, thereby improving the accuracy of the obtained shell temperature.

[0083] In the embodiment of the present application, the pull-up resistor value is an adjustable resistance value, so that the shell temperature test circuit can be flexibly set, which facilitates the selection of a suitable pull-up resistor according to different scenario requirements.

[0084] In an achievable scenario, for example, refer to Figure 5 As shown, Figure 5 The present invention is a schematic diagram of a hardware circuit for testing the shell temperature of a thermoelectric cooling element in a vehicle. A resistor-capacitor filter can also be arranged between the MCU and the TEC to achieve high filtering efficiency and the functions of voltage reduction and current limiting.

[0085] Reference Figure 5 It can be seen that MCU can obtain the input voltage Vadc of the thermistor temperature measurement of TEC;

[0086] Based on the input voltage Vadc, the pull-up resistance value Rh and the pull-up voltage value Vh, the thermistor value Rt is determined. Here, based on the input voltage Vadc, the pull-up resistance value Rh and the pull-up voltage value Vh, the thermistor value Rt can be determined by the following formula (3):

[0087] Rt=Rh*Vadc / (Vh-Vadc) formula (3);

[0088] Furthermore, the method for obtaining the shell temperature Tt of the TEC is as follows: first, Rt is calculated by the formula; second, the corresponding relationship of the selected thermistor specification table is found by the Rt value to obtain the current shell temperature Tt of the TEC. In this way, if the thermistor can be accurately calibrated, the Tt temperature can also be calibrated and adjusted according to actual needs.

[0089] In some embodiments of the present application, Figure 1 In step 101, the controller of the vehicle computer is powered on, and after obtaining the shell temperature of the thermoelectric cooling element in the vehicle computer, the following steps may also be performed: Figure 6 Steps shown:

[0090] Step 105: If the shell temperature meets the fourth temperature range, control the thermoelectric cooling element to refrigerate and / or the fan assembly to operate until the collected shell temperature of the thermoelectric cooling element meets the first temperature range.

[0091] Exemplarily, the fourth temperature range is (65° C., 80° C.), and the fourth temperature range can be set according to actual needs, and this application does not make any specific limitation on this.

[0092] Here, when Tt≥65°C, the thermoelectric cooling element is turned on for cooling and / or the fan assembly is turned on, and the thermoelectric cooling element and the fan assembly work together to dissipate heat to achieve the purpose of rapid heat dissipation.

[0093] In some embodiments of the present application, Figure 1 In step 101, the controller of the vehicle computer is powered on, and after obtaining the shell temperature of the thermoelectric cooling element in the vehicle computer, the following steps may also be performed: Figure 7 Steps shown:

[0094] Step 106: If the shell temperature meets the fifth temperature range, control the thermoelectric cooling element to heat until the collected shell temperature of the thermoelectric cooling element meets the preset temperature.

[0095] Exemplarily, the fifth temperature range is (-25°C, -15°C). The fifth temperature range can be set according to actual needs, and this application does not make any specific limitations on this.

[0096] Here, when Tt<-25℃, the thermoelectric cooling element is controlled to heat; when Tt temperature>-15℃, the heating is stopped. In this way, when the shell temperature of the thermoelectric cooling element is in the fifth temperature range, the thermoelectric cooling element is controlled to heat, and when the shell temperature of the thermoelectric cooling element is in the fourth temperature range, the thermoelectric cooling element and / or the fan assembly are controlled to dissipate heat, thereby flexibly controlling the shell temperature of the thermoelectric cooling element within a certain safety range.

[0097] In a feasible vehicle temperature control scenario, refer to Figure 8 As shown,

[0098] S301, whether the MPU has been started;

[0099] S302, when the MPU is not started, controlling the MCU to power on and detecting the shell temperature Tt of the TEC;

[0100] S303, whether the shell temperature Tt of TEC is within the MPU startup prohibition temperature range;

[0101] Here, the startup prohibition temperature range includes a low temperature range and a high temperature range. For example, the low temperature range may include less than or equal to -25°C, and the high temperature range may include greater than or equal to 80°C.

[0102] S304, MCU controls the fan and / or TEC to dissipate heat, or MCU controls TEC to heat;

[0103] When the shell temperature Tt of TEC is in the low temperature range, the MCU controls the TEC to heat the device; when the shell temperature Tt of TEC is in the high temperature range, the MCU controls the fan and / or TEC to dissipate heat.

[0104] S305, whether the shell temperature Tt of TEC is within the starting temperature range;

[0105] The starting temperature range refers to the aforementioned second temperature range, for example (-15°C, 80°C).

[0106] S306, MCU controls the power supply system to power on the MPU;

[0107] S307, when the MPU has been started, determining whether the shell temperature Tt of the TEC is within the high temperature protection range;

[0108] S308, the shell temperature Tt of TEC is within the high temperature protection range, and the high temperature protection strategy is started;

[0109] The high temperature protection range may include the above-mentioned high temperature range, and the high temperature protection strategy includes controlling the MPU to shut down. Of course, the high temperature protection range may also include a third temperature range, that is, greater than or equal to 70°C, and the high temperature protection strategy includes adjusting the fan speed F to the upper speed threshold to achieve rapid heat dissipation.

[0110] S309: When the MPU has been started, determine whether the shell temperature Tt of the TEC is within the low temperature protection range;

[0111] S310, TEC shell temperature Tt is within the low temperature protection range, and the low temperature protection strategy is started;

[0112] The low temperature protection range may include the above-mentioned low temperature range, and the low temperature protection strategy may include controlling the TEC to heat or controlling the MPU to shut down.

[0113] S311, TEC shell temperature Tt is neither in the high temperature protection range nor in the low temperature protection range, then the MPU works normally.

[0114] In this way, in order to deal with the situation where the temperature inside the car is too high or too low and may cause damage to the MPU, the present application can check the temperature of the MPU after the MCU is started and before the MPU is started. When the temperature does not meet the MPU startup temperature, temperature control can be performed to prevent the MPU from being started directly at a non-operating temperature and causing damage to the MPU. At the same time, the fan speed can be adjusted in accordance with the volume during startup to effectively cover up the problem of excessive fan noise.

[0115] It should be noted that, for the description of the same steps and the same contents in this embodiment as those in other embodiments, reference can be made to the description in other embodiments and will not be repeated here.
