Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
An exemplary embodiment of the present disclosure provides a cooling control method for a vehicle, and an execution subject of the method may be an electronic device, which may be, for example, an in-vehicle terminal of the vehicle. Referring to fig. 1, the cooling control method for the vehicle includes steps S11 to S13. Specifically, the method comprises the following steps:
step S11: a current opening degree signal of an accelerator and a current temperature of a coolant for cooling a drive system of the vehicle are acquired.
In the present embodiment, the throttle opening signal is the throttle opening, which represents the power demand of the driver, and the larger the throttle opening, the larger the power demand.
In this embodiment, the cooling fluid is a cooling medium, which circulates in the cooling pipe, takes away heat generated by the driving motor and the controllers in the driving system, and exchanges heat with the radiator.
It should be understood that the greater the throttle opening, the greater the power demand, i.e., the greater the power of the drive motor in the drive system. Accordingly, the more susceptible the drive system is to overheating while the vehicle is operating at this power. Considering that the accelerator opening signal can reflect the characteristic of whether the driving system is overheated or not, the current opening signal of the accelerator and the current temperature of cooling liquid for cooling the driving system are utilized to determine the operating parameters of the target equipment, and before the driving system is overheated, the driving system is subjected to cooling intervention.
Step S12: and determining the operation parameters of the target equipment according to the current opening degree signal and the current temperature.
In this embodiment, the target device includes a water pump for adjusting the flow rate of the coolant and/or a fan for cooling the drive system.
Step S13: and controlling the running state of the target equipment according to the running parameters so as to cool the driving system.
The drive system is cooled by controlling the operating state of the water pump, such as the duty cycle of the control power, and/or the fan, such as the fan speed.
By adopting the technical scheme, the magnitude of the throttle opening signal reflects the magnitude of the power demand, the magnitude of the power demand depends on the power of a driving motor in a driving system, and the larger the power is, the more easily the power is, the heat is generated, therefore, the throttle opening signal can indirectly reflect whether the driving system is overheated or not.
In order to make the technical solutions provided by the embodiments of the present disclosure more clearly understood by those skilled in the art, the cooling control method for a vehicle provided by the embodiments of the present disclosure is described in detail below.
In a possible implementation manner, the electronic device is preset with a correlation between the opening degree signal, the temperature and the operation parameter, in this case, the step S12 may specifically include the flow steps shown in fig. 2, please refer to fig. 2, and the step S12 may include, for example:
step S1211: and determining a target accelerator opening degree grade corresponding to the current opening degree signal according to the current opening degree signal.
In this embodiment, a target opening degree signal range matched with the current opening degree signal is determined according to the magnitude of the current opening degree signal and a plurality of preset association relations between the opening degree signal ranges and the accelerator opening degree grades, and the accelerator opening degree grade corresponding to the target opening degree signal range is determined as the target accelerator opening degree grade.
Step S1212: and determining a target temperature grade corresponding to the current temperature according to the current temperature.
In this embodiment, a target temperature range matching the current temperature is determined according to the magnitude of the current temperature and a preset association relationship between a plurality of temperature ranges and temperature levels, and a temperature opening level corresponding to the target temperature range is determined as a target temperature level.
Step S1213: and determining the operation parameters corresponding to the target accelerator opening degree grade and the target temperature grade according to the target accelerator opening degree grade, the target temperature grade and preset incidence relations among the accelerator opening degree grade, the temperature grade and the operation parameters.
In this embodiment, different target accelerator opening levels and different target temperature levels correspond to different operating parameters. For example, with the operating parameters including the water pump duty ratio and the fan speed, referring to fig. 3, the present disclosure provides a schematic diagram of the operating parameters of the target device, where the accelerator opening corresponds to the coolant temperature, and the abscissa of the schematic diagram is the accelerator opening and the ordinate is the coolant temperature. Specifically, the method comprises the following steps:
the relationship between the accelerator opening range and the accelerator level may be, for example: the range of the opening degree of the accelerator is 0-15%, and the corresponding grade of the accelerator is 1 grade; the range of the accelerator opening is 15% to 30%, the corresponding accelerator level is 2, the range of the accelerator opening is 30% to 45%, the corresponding accelerator level is 3, the range of the accelerator opening is 45% to 65%, the corresponding accelerator level is 4, the range of the accelerator opening is 65% to 85%, the corresponding accelerator level is 5, the range of the accelerator opening is 85% to 100%, and the corresponding accelerator level is 6.
The correlation between the temperature range and the temperature level may be, for example: the temperature range is 0 ℃ to 55 ℃, and the corresponding temperature grade is 1 grade; the temperature range is 55 ℃ to 65 ℃, and the corresponding temperature grade is 2 grade; the temperature range is greater than 65 ℃, and the corresponding temperature grade is 3 grades.
The preset association relationship among the accelerator opening degree grade, the temperature grade and the operation parameters may be, for example:
when the current accelerator opening acquired by the electronic equipment is between 0% and 15% and the current temperature is between 0 ℃ and 55 ℃, the determined operation parameters comprise that the duty ratio of the water pump is 10%;
when the current accelerator opening acquired by the electronic equipment is between 15% and 30% and the current temperature is between 0 ℃ and 55 ℃, the determined operation parameters comprise a water pump duty ratio of 20%;
when the current accelerator opening acquired by the electronic equipment is between 30% and 45% and the current temperature is between 0 ℃ and 55 ℃, the determined operation parameters comprise a water pump duty ratio of 40%;
when the current accelerator opening acquired by the electronic equipment is between 45% and 65% and the current temperature is between 0 ℃ and 55 ℃, the determined operation parameters comprise a water pump duty ratio of 60%;
when the current accelerator opening acquired by the electronic equipment is between 65% and 85% and the current temperature is between 0 ℃ and 55 ℃, the determined operation parameters comprise a water pump duty ratio of 80%;
when the current accelerator opening acquired by the electronic equipment is between 85% and 100% and the current temperature is between 0 ℃ and 55 ℃, the determined operation parameters comprise a water pump duty ratio of 80%;
when the current accelerator opening obtained by the electronic equipment is between 0% and 85% and the current temperature is between 55 ℃ and 65 ℃, the determined operation parameters comprise that the duty ratio of a water pump is 60% and the rotating speed of a fan is a first rotating speed;
when the current accelerator opening obtained by the electronic equipment is between 0% and 85% and the current temperature is above 65 ℃, the determined operation parameters comprise that the duty ratio of the water pump is 80% and the rotating speed of the fan is a second rotating speed.
When the current accelerator opening obtained by the electronic equipment is between 85% and 100% and the current temperature is above 55 ℃, the determined operation parameters comprise that the duty ratio of the water pump is 80% and the rotating speed of the fan is a second rotating speed.
Note that the first rotational speed is lower than the second rotational speed, and in fig. 3, the first rotational speed means a low speed and the second rotational speed means a high speed. The present embodiment may set the values of the first rotational speed and the second rotational speed according to actual requirements.
In the above example, when the accelerator opening is large and the coolant temperature is high, the requirement for rapid cooling of the drive system can be met by determining only one operating parameter of the target device, so as to ensure that the consumption of power resources is reduced to the greatest extent under the condition that the drive system is cooled; and when the accelerator opening is too large and the temperature of the cooling liquid is too high, the operation parameters of two target devices can be determined so as to meet the cooling requirement on the driving system and reduce the risk of overheating of the driving system to the maximum extent.
In another embodiment, in consideration of the influence of the temperature of the driving system itself on determining the operation parameters, specifically, referring to fig. 4, the step S12 may include, for example:
step S1221: and acquiring the current temperature of the driving system.
Step S1222: and determining a target accelerator opening degree grade corresponding to the current opening degree signal according to the current opening degree signal.
Step S1222 is similar to step S1211 in fig. 2, and is not described herein again.
Step S1223: and determining a target temperature grade corresponding to the current temperature according to the current temperature of the cooling liquid.
Step S1223 is similar to step S1212 in fig. 2, and is not described herein again.
Step S1224: and determining the current temperature of the driving system, the target accelerator opening degree grade and the target temperature grade, and the operation parameters corresponding to the target temperature grade according to the preset incidence relation among the current temperature of the driving system, the target accelerator opening degree grade, the target temperature grade and the temperature grade of the driving system.
In the above embodiment, the influence of the temperature of the driving system on the determined operation parameters is considered, the preset association relationship among the temperature of the driving system, the accelerator opening degree grade, the temperature grade and the operation parameters is established, and the operation parameters are determined according to the current temperature of the driving system, the target accelerator opening degree grade, the target temperature grade and the association relationship, so that the determined operation parameters are more reasonable.
In this embodiment, the water pump is controlled to operate at the duty ratio of the water pump according to the duty ratio of the water pump, so as to regulate and control the flow of the cooling liquid, and the cooling liquid continuously absorbs heat generated by a driving motor in a driving system in a circulating process; the fan is controlled to operate at the fan rotating speed according to the fan rotating speed, so that the fan accelerates the flow of air, heat generated by a driving system can exchange heat with the flowing air, and the purpose of heat dissipation is achieved. Meanwhile, the service life of the driving motor is prolonged, and the vehicle maintenance cost caused by the problems is reduced.
Referring to fig. 5, an exemplary embodiment of the present disclosure also provides a cooling control method for a vehicle, which includes steps S21 through S23.
Step S21: a current opening degree signal of an accelerator and a current temperature of a coolant for cooling a drive system of the vehicle are acquired.
Step S21 is similar to step S11 in fig. 1, and is not repeated here.
Step S22: and under the condition that n continuous current opening signals are all larger than a preset opening value, selecting any one current opening signal from the n current opening signals, and determining the operating parameters of the target equipment according to the current opening signal and the current temperature.
N is a natural positive integer and may be set according to actual conditions. This embodiment is not limited in any way.
The preset opening degree value may be set according to actual conditions. This embodiment is not limited in any way.
It can be understood that, in order to further reduce the risk of overheating of the driving system, since the larger the opening signal of the accelerator (the larger the demand of the accelerator), the more easily the driving system generates an overheating phenomenon, the electronic device may select the largest current opening signal of the n current opening signals as a basis for determining the operation parameter of the target device, so as to ensure that the driving system is prevented from generating the overheating condition to the greatest extent.
Step S23: and controlling the running state of the target equipment according to the running parameters so as to cool the driving system.
Step S23 is similar to step S13 in fig. 1, and is not repeated here.
In this embodiment, under the condition that n current opening signals continuously acquired by the electronic device are all larger than a preset opening value, the operating parameters of the target device are determined according to one current opening signal of the n acquired current opening signals and the current temperature, so that unnecessary operations executed by the electronic device and the target device due to instantaneous large accelerator requirements or single data abnormality are avoided, and unnecessary power consumption is reduced.
