Technical Field

[0001] This application relates to the field of vehicle engine control technology, and in particular to a cooling control method, device, vehicle, medium and product for a vehicle engine. Background Technology

[0002] Engines generate a lot of heat during operation, which needs to be removed in time by a cooling control system to maintain the engine operating within a suitable temperature range, thereby ensuring combustion efficiency and the service life of components.

[0003] In related technologies, cooling control systems typically monitor parameters such as coolant temperature to control the operating status of electric water pumps and electronic thermostats, thereby regulating the coolant flow rate and direction.

[0004] However, in related technologies, low-level or non-intelligent cooling systems often exhibit lag in cooling response under complex operating conditions, potentially leading to unstable engine temperature control. For example, under high-load climbing conditions, cooling lag can easily cause fluctuations in engine coolant temperature; in extremely cold environments, cold start warm-up times are prolonged, affecting vehicle performance and comfort. More seriously, when abnormal situations such as coolant loss or electric water pump communication failure occur, the cooling system lacks an effective sensing and compensation mechanism, failing to replenish coolant or take protective measures in a timely manner. This could potentially lead to engine overheating, damage, or even safety risks, urgently requiring a solution. Summary of the Invention

Detailed Implementation

[0028] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0029] The following description, with reference to the accompanying drawings, describes a vehicle engine cooling control method, apparatus, vehicle, medium, and product according to embodiments of this application. Addressing the technical problems mentioned in the background art, such as lag in cooling system response leading to water temperature fluctuations and prolonged cold start warm-up, and the lack of effective sensing and compensation mechanisms potentially causing insufficient coolant replenishment, resulting in engine overheating and component damage, thus affecting the reliability and safety of the entire vehicle, this application provides a vehicle engine cooling control method. In this method, by analyzing road conditions or the driver's driving habits, it predicts whether the vehicle is about to enter a cooling phase and controls pre-cooling components such as the electric water pump and electronic thermostat to perform pre-cooling speed regulation actions in advance. This helps the cooling system proactively and proactively manage engine temperature, preventing delayed water temperature regulation due to late cooling system intervention, thereby avoiding power reduction or poor combustion caused by excessively high or low water temperatures. Simultaneously, it can preheat the coolant, shorten warm-up time, reduce pollutant emissions from low-temperature combustion, and improve engine efficiency and overall vehicle environmental performance. This solves the problem of delayed response in the cooling system, which easily leads to water temperature fluctuations and prolonged cold start warm-up. At the same time, the lack of an effective sensing and compensation mechanism may result in the coolant not being replenished in time, which could cause engine overheating and component damage, affecting the reliability and safety of the entire vehicle.

[0030] Before describing the vehicle engine cooling control method provided in the embodiments of this application, the system structure and application scenarios involved in the embodiments of this application will be described first.

[0031] like Figure 1 As shown, taking a hybrid engine as an example, in the embodiments of this application, the components involved in the cooling system with intelligent temperature control may include, but are not limited to, the engine body 101, the electronically controlled thermostat 102, the electric water pump 103, the radiator 104, the network-connected ECU (Electronic Control Unit) 105, the vehicle external data acquisition device 106, the coolant auxiliary heater 107, the expansion tank 108, the ethylene glycol raw material storage tank 109, the vehicle exhaust condensation device 1010, and the condensate after-treatment device 1011.

[0032] It can be noted that the system structure provided in this application embodiment differs from the conventional engine cooling system. In this application embodiment, a coolant auxiliary heater 107 is connected in series between the electric water pump 103 and the engine body 101. The ECU 105 is connected to the electric water pump 103 via hard wiring to complete PWM and LIN communication, and is also connected to the heater 107 and the vehicle external data acquisition device 106 via hard wiring. An ethylene glycol raw material storage tank 109, an exhaust gas condensation device 1010, and a condensate after-treatment device 1011 are provided in front of the expansion tank 108.

[0033] Among them, the electronically controlled thermostat 102 and the electric water pump 103 can jointly achieve precise control of coolant flow and temperature; the radiator 104 can release the heat absorbed by the coolant to the environment; the network-connected ECU 105 can combine with the vehicle's external data acquisition equipment 106 to intelligently schedule the cooling strategy based on the operating conditions; the coolant auxiliary heater 107 can heat the coolant at low temperatures, shortening the engine warm-up time; the expansion tank 108 can be used for liquid storage and buffering system pressure fluctuations; the ethylene glycol stock solution storage tank 109 can provide antifreeze and anti-boiling coolant replenishment; the automotive exhaust gas condensation device 1010 can utilize the waste heat of exhaust gas to recover energy from the coolant, while the condensate after-treatment device 1011 can purify the exhaust gas condensate to prevent corrosion or pollution.

[0034] These components work together to realize the vehicle engine cooling control method provided in the embodiments of this application, thereby achieving precise adjustment and environmentally friendly control of engine cooling, and improving power performance and overall vehicle operating efficiency.

[0035] Specifically, Figure 2 This is a schematic flowchart illustrating a cooling control method for a vehicle engine provided in an embodiment of this application.

[0036] like Figure 2 As shown, the cooling control method for the vehicle engine includes the following steps: In step S201, road condition information of the vehicle is collected, or the user's vehicle owner behavior is predicted based on the user's historical driving data.

[0037] It is understood that the embodiments of this application can collect road condition information based on the ECU in conjunction with the vehicle's external data acquisition equipment. The road condition information may include, but is not limited to, typical operating conditions such as long uphill climbs, long downhill climbs, and high-speed cruising. Alternatively, the user's historical driving data can be obtained based on records from the vehicle information system or cloud platform, thereby predicting the driver's driving habits, such as the daily start-up time pattern, commonly used driving routes, or typical acceleration methods. These factors will significantly affect the engine's thermal load and cooling requirements, and can provide predictive and personalized adjustment basis for cooling control. These can be set by those skilled in the art according to actual conditions, and no specific limitations are made here.

[0038] In step S202, the cooling scenario that the car is about to enter is predicted based on road condition information or the driver's behavior.

[0039] Cooling scenarios can refer to operating conditions where the engine experiences increased heat load, temperature rise, or other cooling interventions during operation. These scenarios include, but are not limited to, specific operating conditions such as prolonged high load, long uphill or downhill climbs, and cold starts in low temperatures.

[0040] In actual implementation, the embodiments of this application can predict whether a car is about to enter a cooling scenario based on road condition information. For example, when it is determined from the road condition information that there is a long uphill section ahead, the engine load is expected to increase and generate more heat, which can be predicted as the car is about to enter a cooling scenario. It can also be predicted based on the driver's driving habits. For example, in winter or low-temperature environments, when the driver is about to start the car, the engine needs to be preheated to quickly reach the ideal operating temperature. This process can also be predicted as the upcoming cooling scenario, which can provide a basis for the advance adjustment of the cooling system.

[0041] It should be noted that in the embodiments of this application, when predicting cooling scenarios based on the driver's driving habits, external environmental conditions should also be considered. Generally, a preheating strategy needs to be implemented in winter or colder environments, while under normal temperature conditions, the vehicle can start normally to avoid unnecessary energy consumption.

[0042] In step S203, a pre-cooling speed regulation action is generated for the cooling component based on the cooling scenario, and the cooling component is controlled to perform the pre-cooling speed regulation action so as to end the pre-cooling speed regulation action before the vehicle enters the cooling scenario.

[0043] It is understandable that cooling components can be parts related to the engine cooling system, including but not limited to electronic thermostats, electric water pumps, radiators, and coolant auxiliary heaters.

[0044] Pre-cooling speed regulation refers to the pre-cooling operation performed by the engine cooling system on the cooling components before the engine enters the cooling demand scenario. This can be adjusting the speed of the electric water pump to change the coolant circulation flow rate to improve or reduce cooling efficiency; or adjusting the opening of the electronic thermostat to accelerate the flow of coolant to the radiator to improve heat dissipation efficiency. It can be set by those skilled in the art according to the actual situation, and no specific restrictions are made here.

[0045] As one possible approach, the engine can be preheated in this embodiment by turning on the electric water pump in advance and using a coolant auxiliary heater connected in series to heat the low-temperature coolant, thereby helping the engine quickly reach the ideal operating temperature, achieving efficient warm-up, and completing the pre-cooling speed regulation action.

[0046] Optionally, in one embodiment of this application, controlling the cooling component to perform a pre-cooling speed regulation action includes: generating a control command for the pre-cooling speed regulation action; and sending the control command to the cooling component based on LIN communication to control the cooling component to perform the pre-cooling speed regulation action.

[0047] LIN communication is a low-speed, low-cost serial communication protocol that typically uses a master-slave structure and a single-wire bidirectional communication method. It can be used for data exchange between automotive ECUs and actuators or sensors.

[0048] As one possible implementation method, the embodiments of this application can issue control commands through the ECU to adjust the start and stop of the electric water pump, electronic thermostat, and radiator in real time, thereby achieving precise control of coolant flow and active management of engine temperature, ensuring safe vehicle operation.

[0049] Optionally, in one embodiment of this application, before sending control commands to the cooling component, the method further includes: determining whether LIN communication has failed; if LIN communication fails, then executing a PWM fault feedback mechanism and a corresponding water pump speed regulation mechanism.

[0050] Among them, PWM communication is a method of transmitting control commands through pulse width modulation signals.

[0051] In the embodiments of this application, the PWM fault feedback mechanism can be achieved by sending a heartbeat signal in reverse through the corresponding PWM pin. Under this mechanism, the cooling component can use the same PWM pin to output a periodic pulse signal (heartbeat signal) to the ECU in reverse, indicating its normal operating status or abnormal condition. The ECU determines whether the cooling component is working properly by detecting the presence, frequency, or duty cycle of the heartbeat signal. If the heartbeat is lost or abnormal, fault diagnosis, alarm, or protection actions can be triggered, thereby enhancing the reliability and safety of the cooling system.

[0052] Furthermore, the embodiments of this application can implement a corresponding water pump speed regulation mechanism, that is, the ECU can adjust the working state or output power of the cooling component (such as an electric water pump) by changing the duty cycle of the signal (the proportion of the high-level time to the whole cycle); for example, the higher the duty cycle, the greater the speed or flow of the electric water pump; the lower the duty cycle, the smaller the output, thereby achieving continuously adjustable control.

[0053] In summary, the embodiments of this application can be configured with dual communication modes. PWM communication can be set as a backup communication mode for LIN communication in case of failure. A PWM fault feedback mechanism and a corresponding water pump speed regulation mechanism are designed in case of LIN communication failure. This enhances the ECU's communication control in case of communication failure of the cooling components and prevents the overall water temperature from running out of control due to the main communication failure of the cooling components.

[0054] Optionally, in one embodiment of this application, the automobile is equipped with an ethylene glycol concentrate storage device and an engine water condensation device, and further includes: calculating the loss value of coolant in the cooling components; and controlling the ethylene glycol concentrate storage device and the engine water condensation device to perform cooling compensation based on the loss value when the loss value is greater than or equal to a preset threshold.

[0055] The calculation method can be based on direct measurement of coolant flow rate and consumption, i.e., recording the change in coolant flow rate and the drop in coolant level per unit time using a flow sensor or coolant level sensor, thereby calculating the loss value; or it can be based on the heat balance method, i.e., calculating the loss caused by coolant evaporation or leakage based on engine heat dissipation power, coolant specific heat capacity, temperature change, and system circulation efficiency. The preset threshold can be set to 5% to 10% of the total capacity of the cooling system, which can be set by those skilled in the art according to actual conditions, and no specific limitation is made here.

[0056] Specifically, the embodiments of this application can monitor the coolant loss value in real time and automatically trigger the coolant compensation operation at the appropriate time. This compensation coolant can be produced by mixing and adjusting the ethylene glycol stock stored in advance in the ethylene glycol stock storage tank and the water produced by the evaporation and condensation of the vehicle exhaust condenser and the condensate after treatment device in an equal proportion, thereby ensuring that the coolant is continuously maintained within the safe capacity range and avoiding the impact of overheating or insufficient cooling on engine performance and life.

[0057] The following examples illustrate the vehicle engine cooling control method of this application.

[0058] (1) Scene 1: As one possible implementation method, this application embodiment can collect current vehicle driving road condition information through vehicle external data acquisition devices (such as vehicle body cameras or LiDAR and other electronic devices), and send it to the network-connected ECU. After processing by the network-connected ECU, it can determine whether the vehicle route is about to enter a steep uphill section (such as a slope angle greater than 30°) or whether the current vehicle load is high (such as the total weight of the vehicle carrying passengers and cargo is greater than 400kg). In this case, a pre-cooling acceleration command is immediately issued to the electric water pump in advance at a certain time (such as 5-10s) to adjust the speed. The target speed value R can be determined based on the cooling strategies of other users passing through this section of road through big data analysis of the network-connected ECU, to prevent water temperature adjustment delay due to late water pump intervention, thereby causing excessive water temperature and reduced vehicle power.

[0059] Optionally, this application embodiment can also determine whether the vehicle is about to enter a long downhill section and send a pre-cooling speed reduction or engine shutdown command to the electric water pump or switch to motor drive at a certain time in advance (such as 5-10 seconds). The target speed value R and engine switching status can also be determined based on the cooling strategies of other users passing through this section of road through big data analysis of the networked ECU, so as to prevent water temperature adjustment delay caused by water pump intervention too late, which would result in low water temperature, poor combustion or fuel waste.

[0060] (2) Scene 2: As another possible implementation, this application embodiment can sense the winter ambient temperature T1 (e.g., -30℃) through external vehicle data acquisition devices (such as vehicle body temperature sensors) and transmit the data to a network-connected ECU. Combined with the driver's driving habits and behaviors, it can predict whether there is a possibility of the driver approaching and starting the vehicle. If so, the network-connected ECU can immediately start the electric water pump and turn on the coolant auxiliary heater added to the cooling system when the driver is 5m away from the vehicle. This is to preheat the coolant to a fixed temperature T2 (e.g., 50℃) in advance, which can shorten the warm-up time in winter, reduce pollutant emissions caused by low-temperature combustion, and provide the driver with warm air temperature in time, avoiding the loss of cooling system water temperature caused by the driver starting the heater.

[0061] According to the vehicle engine cooling control method proposed in this application embodiment, by analyzing the vehicle's driving conditions or the driver's driving habits, it predicts whether the vehicle is about to enter a cooling scenario and controls pre-cooling components such as electric water pumps and electronic thermostats to perform pre-cooling speed regulation actions in advance. This can help the cooling system actively and proactively manage engine temperature, preventing water temperature regulation delays caused by late intervention of the cooling system, thereby avoiding power reduction or poor combustion caused by excessively high or low water temperatures. At the same time, it can also preheat the coolant, shorten the warm-up time, reduce pollutant emissions from low-temperature combustion, and improve engine efficiency and overall vehicle environmental performance.

[0062] Next, referring to the accompanying drawings, a cooling control device for a vehicle engine according to an embodiment of this application is described.

[0063] Figure 3 This is a block diagram of a vehicle engine cooling control device according to an embodiment of this application.

[0064] like Figure 3 As shown, the cooling control device 10 for the vehicle engine includes: a data acquisition module 100, a prediction module 200, and a control module 300.

[0065] Among them, the data collection module 100 is used to collect road condition information of the vehicle or to predict the user's car owner behavior based on the user's historical driving data; The prediction module 200 is used to predict the cooling scenario that the car will enter based on road condition information or driver behavior. The control module 300 is used to generate a pre-cooling speed regulation action for the cooling component according to the cooling scenario, and control the cooling component to perform the pre-cooling speed regulation action so as to end the pre-cooling speed regulation action before the vehicle enters the cooling scenario.

[0066] Optionally, in one embodiment of this application, the control module 300 includes a generation unit and a control unit.

[0067] The generation unit is used to generate control commands for the pre-cooling speed regulation action. The control unit is used to send control commands to the cooling components via LIN communication to control the cooling components to perform pre-cooling speed regulation actions.

[0068] Optionally, in one embodiment of this application, it further includes a judgment module and a speed regulation module.

[0069] The judgment module is used to determine whether LIN communication has failed. The speed control module is used to execute the PWM fault feedback mechanism and the corresponding water pump speed control mechanism if LIN communication fails.

[0070] Optionally, in one embodiment of this application, it further includes a calculation module and a compensation module.

[0071] The calculation module is used to calculate the coolant loss value in the cooling components. The compensation module is used to control the ethylene glycol concentrate storage device and the engine water condensation device to perform cooling compensation based on the loss value when the loss value is greater than or equal to a preset threshold.

[0072] It should be noted that the explanation of the above-described embodiment of the vehicle engine cooling control method also applies to the vehicle engine cooling control device of this embodiment, and will not be repeated here.

[0073] The vehicle engine cooling control device proposed in this application analyzes the vehicle's driving conditions or the driver's driving habits to predict whether the vehicle is about to enter a cooling scenario. It then controls pre-cooling components such as the electric water pump and electronic thermostat to perform pre-cooling speed regulation actions in advance. This helps the cooling system to proactively and proactively manage engine temperature, preventing water temperature regulation delays caused by late intervention of the cooling system. This avoids power loss or poor combustion caused by excessively high or low water temperatures. At the same time, it can also preheat the coolant, shorten the warm-up time, reduce pollutant emissions from low-temperature combustion, and improve engine efficiency and overall vehicle environmental performance.

[0076] Furthermore, the vehicle also includes: Communication interface 403 is used for communication between memory 401 and processor 402.

[0077] The memory 401 is used to store computer programs that can run on the processor 402.

[0078] Memory 401 may include high-speed RAM memory, and may also include non-volatile memory, such as at least one disk storage device.

[0079] If the memory 401, processor 402, and communication interface 403 are implemented independently, then the communication interface 403, memory 401, and processor 402 can be interconnected via a bus to complete communication between them. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. Buses can be categorized as address buses, data buses, control buses, etc. For ease of representation, Figure 4 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0080] Optionally, in a specific implementation, if the memory 401, processor 402, and communication interface 403 are integrated on a single chip, then the memory 401, processor 402, and communication interface 403 can communicate with each other through an internal interface.
