Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and particularly to a temperature control method, device, equipment and storage medium based on a thermostat. Background Art

[0002] A thermostat is a key component that controls the flow path of the coolant in an internal combustion engine. The thermostat automatically adjusts the amount of water entering the radiator according to the water temperature to ensure that the internal combustion engine operates within a reasonable temperature range.

[0003] Generally, the thermostat is a wax-type thermostat. The wax-type thermostat controls the coolant circulation mode according to the principle of thermal expansion and contraction of the paraffin inside. When the coolant temperature is lower than a certain value, the paraffin inside the thermostat is in a solid state, and the coolant undergoes a small cycle flow. When the coolant temperature reaches a certain value, the paraffin gradually melts into a liquid to open the valve, and the coolant undergoes a large cycle flow. This wax-type thermostat has a simple structure, but it often opens and closes during operation, causing the temperature of the coolant in the internal combustion engine to oscillate. The ideal coolant temperature of the internal combustion engine under different operating conditions of the vehicle is different, but due to the same opening temperature of the wax-type thermostat, the requirement of the ideal coolant temperature of the vehicle under different operating conditions cannot be met.

[0029] Embodiment 1

[0030] Figure 1 FIG. 10 is a flowchart of a temperature control method based on a thermostat provided for Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the temperature of the internal combustion engine of a vehicle under any operating condition. This method can be executed by a temperature control device based on a thermostat. The temperature control device based on a thermostat can be implemented in the form of hardware and / or software, and the temperature control device based on a thermostat can be configured in various general computing devices. As Figure 1 shown, the method includes:

[0031] S110. Collect the real-time coolant temperature of the target vehicle under the current operating condition.

[0032] Among them, the target vehicle may refer to the vehicle to be controlled for the temperature of the internal combustion engine, and the current operating condition may refer to the real-time condition of the target vehicle at the current moment.

[0033] Specifically, the signal data of the in-vehicle sensors of the target vehicle can be collected in real time through the ECU (Electronic Control Unit) of the target vehicle, such as ambient temperature data, coolant temperature data, engine speed data, engine torque data, thermostat opening data, and retarder opening flag data. It should be noted that the operating condition of the vehicle can be represented by the signal data of the in-vehicle sensors.

[0034] S120. Determine a candidate temperature range under the current operating condition based on the vehicle coolant temperature gauge and the coolant temperature deviation table, and determine the target temperature range from the candidate temperature range according to the real-time coolant temperature.

[0035] Among them, the candidate temperature range can be used to represent the temperature partition of the coolant corresponding to the target vehicle under the current operating condition. For example, it can include a first low-temperature range, a second low-temperature range, a normal temperature range, a first high-temperature range, and a second high-temperature range. It should be noted that the temperature of the first low-temperature range is lower than that of the second low-temperature range, and the temperature of the second high-temperature range is higher than that of the first temperature range.

[0036] The target temperature range can refer to the candidate temperature range in which the real-time coolant temperature of the target vehicle is located.

[0037] The vehicle coolant temperature gauge records the candidate reference coolant temperatures corresponding to the target vehicle under at least two historical operating conditions; the coolant temperature deviation table records the candidate temperature deviation parameters corresponding to the target vehicle under at least two historical operating conditions. It should be noted that in the embodiments of the present invention, the vehicle coolant temperature gauge and the coolant temperature deviation table can record all operating conditions of the vehicle operation, and the setting of the specific number of operating conditions can be adaptively set by those skilled in the art.

[0038] It should be noted that the candidate reference coolant temperature can be the temperature average value of at least two coolant temperatures corresponding to the historical operating conditions collected during the historical data collection period; the candidate temperature deviation parameters can be divided into a first group of temperature deviations greater than the candidate reference coolant temperature and a second group of temperature deviations less than the candidate reference coolant temperature; and each group of temperature deviations includes a maximum temperature deviation value and a minimum temperature deviation value. Exemplarily, the first group of temperature deviations can include a first deviation upper limit parameter and a second deviation upper limit parameter, and the second group of temperature deviations can include a first deviation lower limit parameter and a second deviation lower limit parameter. Optionally, the historical data collection period can be adaptively set by those skilled in the art.

[0039] Optionally, in the embodiments of the present invention, the operating condition of the target vehicle can be represented by vehicle operating parameters, and the vehicle operating parameters can be adaptively set by those skilled in the art. Exemplarily, the vehicle operating parameters can be the engine speed and the engine torque. In other words, the vehicle coolant temperature gauge can be used to record the mapping relationship between the engine speed and the engine torque corresponding to the target vehicle under different historical operating conditions and the candidate reference coolant temperature corresponding to this historical operating condition, and the coolant temperature deviation table can be used to record the mapping relationship between the engine speed and the engine torque corresponding to the target vehicle under different historical operating conditions and the candidate temperature deviation parameters corresponding to this historical operating condition.

[0040] S130. Determine the target control parameter of the thermostat based on the target temperature range, and perform temperature adjustment according to the target control parameter.

[0041] Specifically, based on the target temperature range determined according to the real-time coolant temperature of the target vehicle, further determine the control parameter of the thermostat corresponding to the target temperature range as the target control parameter, and perform temperature control on the internal combustion engine.

[0042] The technical solution of the embodiment of the present invention constructs the candidate reference coolant temperatures corresponding to multiple historical operating conditions of the target vehicle, and the candidate temperature deviation parameters corresponding to multiple historical operating conditions of the target vehicle, and then determines the target temperature range in which the real-time coolant temperature of the target vehicle is located under the current operating condition, and determines the target control parameter of the target vehicle under the current operating condition according to the target temperature range, realizing that the target vehicle can dynamically control the temperature control range of the coolant according to the current operating condition to meet the coolant temperature control requirements of the target vehicle under different operating conditions, and ensuring the stable operation of the internal combustion engine of the target vehicle under different operating conditions.

[0043] Embodiment Two

[0044] Figure 2a As shown in the flowchart of a temperature control method based on a thermostat provided in Embodiment Two of the present invention, this embodiment is further refined on the basis of the above embodiment, and provides specific steps for determining the candidate temperature range under the current operating condition based on the vehicle coolant temperature table and the coolant temperature deviation table, and determining the target temperature range from the candidate temperature range according to the real-time coolant temperature. It should be noted that for the parts not detailed in the embodiment of the present invention, reference can be made to the relevant descriptions of other embodiments, which will not be elaborated here. As Figure 2a shown, the method includes:

[0045] S210. Collect the real-time coolant temperature of the target vehicle under the current operating condition.

[0046] S220. Traverse the vehicle coolant temperature table according to the vehicle operating parameters of the target vehicle under the current operating condition, and use the candidate reference coolant temperature corresponding to the historical operating condition matching the current operating condition as the target reference coolant temperature.

[0047] Specifically, the vehicle coolant temperature table can be traversed according to the vehicle operating parameters of the target vehicle under the current operating condition, the historical operating condition that conforms to the vehicle operating parameters under the current operating condition is determined in the vehicle coolant temperature table, and the candidate reference coolant temperature corresponding to the historical operating condition in the vehicle coolant temperature table is used as the target reference coolant temperature.

[0048] Optionally, in the embodiments of the present invention, the vehicle operating parameters corresponding to the operating conditions of the vehicle can be adaptively set by those skilled in the art. Exemplarily, the vehicle operating parameters can be the engine speed and the engine torque.

[0049] S230. Traverse the coolant temperature deviation table according to the current vehicle operating parameters of the target vehicle under the current operating condition, and use the candidate temperature deviation parameter corresponding to the historical operating condition matching the current operating condition as the target temperature deviation parameter.

[0051] Optionally, after determining the target reference coolant temperature, the target reference coolant temperature can also be corrected according to the real-time ambient temperature data of the environment where the target vehicle is located. It should be noted that the ambient temperature of the vehicle has a relatively obvious impact on the heat dissipation of the vehicle's internal combustion engine. For example, in summer and winter, the heat dissipation performance of the vehicle is significantly different.

[0052] Optionally, the target reference coolant temperature can be corrected according to the ambient temperature correction table. It should be noted that the ambient temperature correction table records the correction relationship between the historical ambient temperature and the target reference coolant temperature of the target vehicle under the historical ambient temperature; optionally, the ambient temperature correction table can be generated by sorting the historical condition data and historical ambient temperature data of the target vehicle.

[0053] By correcting the target reference coolant temperature according to the ambient temperature, the influence of the ambient temperature on the target reference coolant temperature is reduced, and the data accuracy of the target reference coolant temperature is improved.

[0054] S240. Determine the candidate temperature range corresponding to the target vehicle under the current operating condition according to the target reference coolant temperature and the candidate temperature deviation parameter, and determine the target temperature range from the candidate temperature range according to the real-time coolant temperature.

[0055] Among them, the candidate temperature range can be at least two temperature ranges formed by dividing the target reference coolant temperature according to the target temperature deviation parameter.

[0056] Optionally, in the embodiments of the present invention, determining a candidate temperature range corresponding to a target vehicle under a current operating condition according to a target reference coolant temperature and candidate temperature deviation parameters includes: performing a difference operation on the target reference coolant temperature, a first deviation lower limit parameter, and a second deviation lower limit parameter to generate a first lower limit coolant temperature and a second lower limit coolant temperature; wherein, the first lower limit coolant temperature is greater than the second lower limit coolant temperature; performing an addition operation on the target reference coolant temperature, a first deviation upper limit parameter, and a second deviation upper limit parameter to generate a first upper limit coolant temperature and a second upper limit coolant temperature; wherein, the second upper limit coolant temperature is greater than the first upper limit coolant temperature, and the first upper limit coolant temperature is greater than the first lower limit coolant temperature; generating a candidate temperature range corresponding to the target vehicle under the current operating condition according to the first lower limit coolant temperature, the second lower limit coolant temperature, the first upper limit coolant temperature, and the second upper limit coolant temperature.

[0057] In a specific implementation manner, as Figure 2b shown, the first lower limit coolant temperature T1 can be determined by subtracting the first deviation lower limit parameter t1 from the target reference coolant temperature T, and the second lower limit coolant temperature T2 can be determined by subtracting the first deviation lower limit parameter t1 and the second deviation lower limit parameter t2 from the target reference coolant temperature T; the first upper limit coolant temperature T3 can be determined by adding the first deviation upper limit parameter t3 to the target reference coolant temperature T, and the second upper limit coolant temperature T4 can be determined by adding the first deviation upper limit parameter t3 and the second deviation upper limit parameter t4 to the target reference coolant temperature T. It should be noted that the temperature range less than or equal to the second lower limit coolant temperature T2 can be the first low temperature range, and the temperature range formed by the second lower limit coolant temperature T2 and the first lower limit coolant temperature T1 can be the second low temperature range; the temperature range formed by the first lower limit coolant temperature T1 and the first upper limit coolant temperature T3 can be the normal temperature range; the temperature range formed by the first upper limit coolant temperature T3 and the second upper limit coolant temperature T4 can be the first high temperature range; the temperature range greater than or equal to the second upper limit coolant temperature T4 can be the second high temperature range.

[0058] S250. Based on the target temperature range, determine the target control parameter of the thermostat, and perform temperature adjustment according to the target control parameter.

[0059] Optionally, based on the target temperature range, the target control parameter of the thermostat is determined, including: if the target temperature range is the temperature range formed by the first lower coolant temperature and the first upper coolant temperature, then according to the vehicle operation parameters of the target vehicle under the current operation condition, the thermostat control parameter table is traversed, and the candidate control parameter corresponding to the historical operation condition consistent with the vehicle operation parameters under the current operation condition is used as the target control parameter; wherein, the thermostat control parameter table records the candidate control parameters of the thermostat corresponding to the target vehicle under at least two historical operation conditions;

[0060] If the target temperature range is less than or equal to the second lower coolant temperature, the target control parameter is the opening value when the thermostat performs the first cycle;

[0061] If the target temperature range is the temperature range formed by the first lower coolant temperature and the second lower coolant temperature, then based on the first lower coolant temperature and the second lower coolant temperature, as well as the candidate control parameter corresponding to the historical operation condition consistent with the vehicle operation parameters of the target vehicle under the current operation condition and the opening value when the thermostat performs the first cycle, the target control parameter is determined;

[0062] If the target temperature range is greater than or equal to the second upper coolant temperature, the target control parameter is the opening value when the thermostat performs the second cycle;

[0063] If the target temperature range is the temperature range formed by the first upper coolant temperature and the second upper coolant temperature, then based on the first upper coolant temperature and the second upper coolant temperature, as well as the candidate control parameter corresponding to the historical operation condition consistent with the vehicle operation parameters of the target vehicle under the current operation condition and the opening value when the thermostat performs the second cycle, the target control parameter is determined; wherein, the first cycle is the cycle in which the coolant does not flow to the radiator, and the second cycle refers to the cycle in which the coolant flows to the radiator.

[0064] In a specific optional implementation manner, the target control parameter in the case where the target temperature range is the temperature range formed by the first lower coolant temperature and the first upper coolant temperature can be denoted as the first control parameter; the target control parameter in the case where the target temperature range is the temperature range less than or equal to the second lower coolant temperature can be denoted as the second control parameter; in the case where the target temperature range is the temperature range formed by the first lower coolant temperature and the second lower coolant temperature, the target control parameter at this time can be: (actual coolant temperature - second lower coolant temperature) / (first lower coolant temperature - second lower coolant temperature)×(first control parameter - second control parameter + second control parameter).

[0065] The target control parameter in the case of a target temperature range greater than or equal to the second upper coolant temperature can be denoted as the third control parameter; in the case where the target temperature range is the temperature range formed by the first upper coolant temperature and the second upper coolant temperature, the target control parameter at this time can be: (real-time coolant temperature - first lower coolant temperature) / (first upper coolant temperature - first lower coolant temperature) × (third control parameter - first control parameter) + first control parameter.

[0066] Optionally, in the embodiment of the present invention, it further includes: if it is detected that the retarder is turned on or a vehicle-mounted device fails, the thermostat is controlled to adjust the coolant temperature with the maximum opening value.

[0067] It should be noted that the failure of the vehicle-mounted device may include the failure of the coolant sensor, the loss of the working signal of the retarder, and the loss or failure of the signal of the electronic control thermostat sensor, etc. And when adjusting the coolant temperature, it will first judge whether the retarder is turned on or whether the vehicle-mounted device fails.

[0068] Optionally, in the embodiment of the present invention, before adjusting the temperature according to the target control parameter, the target control parameter can be filtered first, and then the filtered target control parameter is sent to the thermostat for temperature adjustment, avoiding the frequent jitter of the thermostat caused by frequent changes in the working conditions.

[0069] The technical solution of the embodiment of the present invention determines the candidate reference coolant temperature corresponding to the historical operating condition matching the current operating condition of the target vehicle, as well as the candidate temperature deviation parameter, determines the candidate temperature range corresponding to the target vehicle under the current operating condition, and determines the target temperature range in which the real-time coolant temperature of the target vehicle is located in the candidate temperature range, realizing the temperature control of the coolant for the distribution dynamics of the target temperature range, while avoiding the frequent jitter control of the thermostat caused by frequent changes in the working conditions, and improving the control efficiency of the temperature control.
