Description
Technical Field
[0001] The present invention relates to the technical field of vehicles, and more particularly, to a vehicle response control method, apparatus, vehicle, and storage medium. Background Art
[0002] In an automotive transmission, the hydraulic system serves as the driving unit for driving transmission actuators (such as clutches and shift actuators), and its performance is directly related to the smoothness of vehicle power transmission; the solenoid valve, as the core component in the hydraulic system, precisely drives the transmission actuators by regulating the flow rate and pressure of hydraulic oil.
[0003] However, in practical applications, the solenoid valve is prone to blockage due to the accumulation of foreign matters such as impurities generated by the aging of hydraulic oil and particulate matter generated by friction during the operation of the hydraulic system. The blockage of the solenoid valve not only leads to a decrease in the control accuracy of the hydraulic system and a sluggish response, causing unevenness during the shifting process and abrupt power connection, but also prolongs the shift response time, making the vehicle driver feel the lag in control response. In severe cases, it may cause overheating and ablation due to the clutch being in a slipping state for a long time, resulting in irreversible damage to the transmission, thereby affecting the overall safety performance and service life of the vehicle.

[0051] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings.
[0052] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.
[0053] Combined with Figure 1 As shown, an embodiment of the present invention provides a vehicle response control method, including:
[0054] Step 100: Determine a preset cleaning mode for the hydraulic system of the vehicle's transmission and a preset cleaning cycle for the preset cleaning mode according to the currently obtained operating parameters of the vehicle and the parameter values corresponding to the operating parameters.
[0055] Step 200: Control the hydraulic system to operate according to the preset cleaning mode to periodically clean the target solenoid valve of the hydraulic system based on the preset cleaning cycle.
[0056] Among them, the operating parameters include vehicle speed, transmission operating state, and total vehicle mileage, and the preset cleaning mode includes at least one of a first cleaning mode corresponding to the vehicle speed, a second cleaning mode corresponding to the transmission operating state, and a third cleaning mode corresponding to the total vehicle mileage.
[0057] The method of this embodiment is applicable to a transmission with a hydraulic system and a vehicle having the transmission, and is used to clean the target solenoid valve in the hydraulic system of the vehicle's transmission. For example, by changing the flow rate and flow velocity of the hydraulic oil flowing through the target solenoid valve, the target solenoid valve can be flushed and cleaned, so as to effectively impact and remove foreign objects that may be blocked at the target solenoid valve, reduce or eliminate the blockage of the target solenoid valve, avoid problems such as a decrease in the sensitivity and response slowness of the target solenoid valve and the hydraulic system caused by foreign object blockage, improve the sensitivity and response rate of the target solenoid valve and the hydraulic system, ensure the normal response of the hydraulic system to corresponding operation instructions, and improve the user experience.
[0058] Specifically, in the method of this embodiment, through step 100, the current operating parameters of the vehicle (such as vehicle speed, driving mileage, gear state and clutch state of the vehicle's transmission, etc.) are obtained in real time, and based on the obtained operating parameters and their corresponding parameter values, a preset cleaning mode applicable to the hydraulic system of the current vehicle's transmission (denoted as the preset cleaning mode) is determined, so as to control the hydraulic system to operate according to the preset cleaning mode corresponding to the operating parameters, realizing the control of the flow rate and flow velocity of the hydraulic oil flowing through the target solenoid valve, and thus realizing the flushing and cleaning of the target solenoid valve through the hydraulic oil in the hydraulic system. Among them, considering that there may be various factors causing foreign matter to block the target solenoid valve, such as the aging and wear of the corresponding vehicle components, the hydraulic system maintaining the same operating mode for a long time, etc., the preset cleaning mode in the method of this embodiment includes a first cleaning mode corresponding to the vehicle speed, a second cleaning mode corresponding to the operating state of the transmission, and a third cleaning mode corresponding to the total driving mileage of the vehicle, so as to comprehensively cope with different situations that may cause the target solenoid valve to be blocked during the vehicle life cycle, thereby facilitating the suppression or reduction of the target solenoid valve blockage situation throughout the vehicle life cycle, ensuring the normal response of the hydraulic system, and improving the user experience throughout the vehicle life cycle. Moreover, considering that the parameter values of the vehicle's operating parameters are dynamically changing, some factors affecting the foreign matter blockage situation of the target solenoid valve come from the actual vehicle operating parameters (such as the current value of the vehicle speed), some factors affecting the foreign matter blockage situation of the target solenoid valve come from the cumulative vehicle operating parameters (such as the cumulative value of the vehicle driving mileage), and the same vehicle operating parameters can correspond to different preset cleaning modes. Therefore, the first cleaning mode, the second cleaning mode, and the third cleaning mode of the preset cleaning mode can be carried out independently or in parallel to achieve dynamic adaptation to the dynamically changing vehicle operating parameters, meet the cleaning requirements in different situations, and improve the cleaning efficiency of the target solenoid valve.
[0059] In this way, based on the acquired current operating parameters of the vehicle and their corresponding parameter values, the method of this embodiment determines the preset cleaning mode applicable to the hydraulic system of the current vehicle's transmission and the determined preset cleaning period, and controls the hydraulic system of the vehicle's transmission to operate according to the preset cleaning mode, so as to periodically clean the target solenoid valve of the hydraulic system based on the preset cleaning period of the preset cleaning mode, enabling the vehicle to obtain the best cleaning effect that can meet the real-time cleaning requirements of the vehicle during the entire period of adopting the preset cleaning mode, thereby effectively reducing solenoid valve blockage and ensuring the normal response of the hydraulic system. Specifically, by controlling the hydraulic system to operate according to at least one of the first cleaning mode, the second cleaning mode, and the third cleaning mode in the preset cleaning mode corresponding to the operating parameters, the flow rate and flow velocity of the hydraulic oil flowing through the target solenoid valve in the hydraulic system are precisely adjusted to ensure that the target solenoid valve is effectively flushed and foreign matters that may accumulate are promptly removed, thereby reducing or avoiding problems such as slow response of the hydraulic system or uneven gear shifting caused by blockage, ensuring smooth connection of the transmission power, and being able to promptly respond to the operation instructions of the user (driver) or the vehicle controller, avoiding the user from significantly feeling the lag of the control response, and avoiding irreversible damage to the transmission caused by overheating and ablation due to the clutch being in a slipping state for a long time due to slow response, which in turn affects the overall safety performance and service life of the vehicle, and improving the overall safety performance and service life of the vehicle.
[0060] Optionally, as shown in combination with Figure 1 、 Figure 2 , step 100 includes:
[0061] Step 110, when adopting the first cleaning mode corresponding to the vehicle speed, determine the corresponding first preset time period as the preset cleaning period according to the value of the vehicle speed;
[0062] Step 200 includes:
[0063] Step 210, control the target solenoid valve of the hydraulic system to be periodically cleaned according to the first preset time period; wherein, during each cleaning, control the target solenoid valve to switch the first preset number of times at the first preset frequency.
[0064] Considering the influence of vehicle speed on the hydraulic oil pressure in the hydraulic system, for example, when the vehicle is running at a low speed or in an idle state, the hydraulic system demand of the transmission is relatively low. For instance, the shifting frequency is low, the clutch pressure demand is low, and the hydraulic system can operate in a low-load mode, maintaining a relatively low oil pressure to save energy and reduce consumption. When the vehicle is running at a high speed, the shifting frequency of the transmission increases, the pressure required for the clutch is higher, and at the same time, it is necessary to maintain the cooling and lubrication of the transmission. This operating condition requires the hydraulic system to provide a larger flow rate and pressure to meet the high-load demand. Moreover, the hydraulic oil pressure affects the cleaning effect. Obviously, the cleaning effect under high oil pressure is better than that under low oil pressure. Under high oil pressure conditions, the hydraulic oil can scour the target solenoid valve in the hydraulic system at a higher flow rate, effectively removing the foreign matter accumulated at the target solenoid valve, thereby reducing the risk of blockage of the target solenoid valve and ensuring the normal operation of the hydraulic system. Under low oil pressure conditions, the flow rate of the hydraulic oil is relatively low, and the cleaning efficiency is relatively weakened. And when the vehicle is running at a high speed, with the increase of the shifting frequency of the transmission, the hydraulic oil in the hydraulic system flows more frequently and at a higher speed, which further enhances the cleaning ability of the hydraulic oil. Therefore, when adopting the first cleaning mode corresponding to the vehicle speed, the cleaning time interval for cleaning the target solenoid valve can be dynamically adjusted according to the vehicle speed. For example, a shorter cleaning time interval is taken at low speed and a longer cleaning time interval is taken at high speed, so as to better match the operating state and cleaning requirements of the hydraulic system, achieve the best balance between the operating efficiency and cleaning effect of the hydraulic system, extend the service life of the transmission and its hydraulic system, and improve the overall performance and reliability of the vehicle.
[0065] The first cleaning mode is a cleaning strategy adapted to the vehicle speed, that is, controlling the target solenoid valve to be periodically cleaned according to the first preset time period corresponding to the specific value of the vehicle speed. Specifically, through step 110, when obtaining the parameter value (numerical value) of the current vehicle speed, the first preset time period for the first cleaning mode corresponding to the current vehicle speed value (that is, the cleaning time interval for cleaning the target solenoid valve) can be determined as the preset cleaning period. Then, through step 210, the hydraulic system can be controlled to operate according to the first cleaning mode to periodically clean the target solenoid valve based on the first preset time period. In this way, on the one hand, it is ensured that during the vehicle operation, the cleaning of the target solenoid valve is carried out according to the preset period corresponding to the current vehicle speed value, so as to better match the operating state and cleaning requirements of the hydraulic system, achieve the best balance between the operating efficiency and cleaning effect of the hydraulic system, extend the service life of the transmission and its hydraulic system, and improve the overall performance and reliability of the vehicle. On the other hand, by periodically cleaning the target solenoid valve, it is ensured that the cleaning of the target solenoid valve during the vehicle operation will not stop (or be interrupted for a long time), so as to effectively prevent the blockage problem of the solenoid valve caused by foreign matter accumulation, ensure that the hydraulic system maintains a sensitive response under different operating conditions, and avoid performance problems such as shifting delay and unevenness.
[0066] Moreover, during each cleaning, the target solenoid valve is controlled to switch on and off at a first preset frequency for a first preset number of times, so as to effectively clean the target solenoid valve. Among them, when foreign matters accumulate inside the target solenoid valve, by performing rapid opening and closing operations on the solenoid valve (i.e., switching on and off at the first preset frequency for the first preset number of times), a pulsed flushing effect on the target solenoid valve is achieved, that is, the target solenoid valve is frequently opened and closed within a short period of time, so that the hydraulic oil forms a strong pulsating flow in the hydraulic system pipeline. This pulsation can enhance the impact force of the hydraulic oil fluid on the pollutants (foreign matters) at the target solenoid valve, and disturb the stubborn foreign matters attached to the pipeline wall and inside the target solenoid valve through the dynamic change of the fluid, so as to more effectively peel and carry them away, realizing the effective cleaning of the target solenoid valve. When the foreign matters are removed, the axial force of the target solenoid valve is enhanced, which can ensure that the target solenoid valve can work stably even under low-pressure conditions, allowing the low-pressure hydraulic oil to flow smoothly from the oil inlet of the target solenoid valve to the oil outlet, and ensuring the normal response of the target solenoid valve and the hydraulic system. Among them, the first preset frequency and the first preset number of times can be set according to actual needs. In some embodiments, the first preset frequency and the first preset number of times can be fixed values corresponding to the first cleaning mode, such as the first preset number of times is taken as 1.
[0067] Optionally, the first preset time period includes a first preset duration, a second preset duration, and a third preset duration, and both the first preset duration and the third preset duration are greater than the second preset duration;
[0068] Determining a corresponding first preset time period as the preset cleaning period according to the value of the vehicle speed includes:
[0069] When the value of the vehicle speed is greater than 0 and less than or equal to the first preset value, determine the first preset duration as the preset cleaning period;
[0070] When the value of the vehicle speed is greater than the first preset value and less than or equal to the second preset value, determine the second preset duration as the preset cleaning period;
[0071] When the value of the vehicle speed is greater than the second preset value, determine the third preset duration as the preset cleaning period.
[0072] Considering that the hydraulic system working conditions of vehicles in different speed ranges are significantly different, targeted adjustment of the cleaning cycle of the solenoid valve can effectively optimize the cleaning strategy. When the vehicle is in a low-speed driving or idling state (such as the speed value is greater than 0 and less than or equal to the first preset value), the oil pressure in the hydraulic system of the transmission is low, and foreign matter in the oil circuit is more likely to accumulate, which may cause the target solenoid valve to be blocked or respond slowly. At this time, a shorter cleaning cycle (i.e., the first preset duration) is adopted to increase the cleaning frequency, so that foreign matter can be removed in time, ensure the normal operation of the solenoid valve, and avoid greater hidden dangers of failure caused by impurity accumulation. In the medium-speed driving state (such as the speed value is greater than the first preset value and less than or equal to the second preset value), the oil pressure and oil flow rate of the hydraulic system are improved, but still insufficient for full self-cleaning. At the same time, medium-speed driving is usually a common speed range for vehicles to run for a long time. Therefore, the cleaning cycle at this time is set to the shortest second preset duration to further increase the cleaning frequency, facilitate the timely removal of foreign matter, maintain the stability of the hydraulic system and the normal response ability of the solenoid valve, etc. When driving at high speed (such as the vehicle speed is greater than the second preset value), the hydraulic system is in a high-load condition, the oil pressure and oil flow rate are significantly increased, and the high-speed flow of hydraulic oil has a certain self-cleaning effect, which can effectively reduce the accumulation of impurities; at the same time, high-speed driving has higher requirements on the performance of the hydraulic system, and frequent cleaning may cause pressure fluctuations and affect the stability of the system; therefore, when driving at high speed, the cleaning cycle is appropriately extended to the third preset time, and the self-cleaning ability of the hydraulic oil is fully utilized, which can not only reduce the frequency of cleaning, but also avoid unnecessary load on the hydraulic system, thereby ensuring the smoothness and efficiency of the cleaning process.
[0073] Specifically, when the vehicle is traveling at a low speed (such as when the speed value is greater than 0 and less than or equal to the first preset value), the preset cleaning cycle for the first cleaning mode takes the first preset duration; when the vehicle is traveling at a medium speed (such as when the speed value is greater than the first preset value and less than or equal to the second preset value), the preset cleaning cycle for the first cleaning mode takes the second preset duration; when the vehicle is traveling at a high speed (such as when the speed value is greater than the second preset value), the preset cleaning cycle for the first cleaning mode takes the third preset duration; and both the first preset duration and the third preset duration are greater than the second preset duration. In this way, by dynamically adjusting the cleaning cycle according to the vehicle's driving speed, it is possible to more effectively adapt to the working conditions of the hydraulic system, optimize the cleaning strategy of the solenoid valve, etc. Among them, the first preset value, the second preset value, the first preset duration, the second preset duration, and the third preset duration can all be set according to actual needs.
[0074] Exemplarily, the first preset value is taken as 30 km / h, the second preset value is taken as 60 km / h, the first preset duration is taken as 40 s, the second preset duration is taken as 30 s, and the value range of the third preset duration is greater than 30 s. Then, when the vehicle speed is greater than 0 and lower than 30 km / h, the preset cleaning cycle is 40 seconds; when the vehicle speed is in the range of 30 to 60 km / h, the preset cleaning cycle is 30 seconds; when the vehicle speed is greater than 60 km / h, the preset cleaning cycle takes a duration greater than 30 s. In some embodiments, the high-speed range can be further subdivided. For example, when the vehicle speed is in the range of 60 to 90 km / h, the value range of the preset cleaning cycle is 30 to 120 seconds; when the vehicle speed is in the range of 90 to 120 km / h, the value range of the preset cleaning cycle is 120 to 300 seconds; when the vehicle speed is higher than 120 km / h, the preset cleaning cycle takes a duration greater than or equal to 300 seconds. In this way, by dynamically adjusting the cleaning cycle according to the vehicle speed, not only can the cleaning frequency be increased for the situation where impurities are likely to accumulate in the hydraulic system during low-speed and medium-speed driving, but also the self-cleaning ability of the hydraulic oil can be fully utilized during high-speed driving to extend the cleaning cycle and reduce the potential interference of cleaning on the system stability. In addition, by further subdividing the high-speed range, the cleaning strategy can be further optimized to balance the stability of the hydraulic system and the cleaning efficiency, meet the performance requirements of the hydraulic system and the solenoid valve under different working conditions, and ensure the reliability and safety of vehicle operation.
[0075] Optionally, as shown in combination with Figure 1 and Figure 3 , the operating state of the transmission includes the gear state and the clutch state of the transmission;
[0076] Step 100 includes:
[0077] Step 120, when adopting the second cleaning mode corresponding to the operating state of the transmission, determine the first preset mileage cycle corresponding to the second cleaning mode as the preset cleaning cycle;
[0078] Step 200 includes:
[0079] Step 220, when the actual driving mileage after the vehicle enters the preset state reaches an integer multiple of the first preset mileage cycle, control the target solenoid valve to switch the second preset number of times at the second preset frequency; where the preset state includes that the gear state remains unchanged and the clutch state is in the engaged state.
[0080] To solve the problem of foreign object accumulation in the target solenoid valve of the transmission hydraulic system due to reduced flow velocity when the vehicle maintains a constant gear state, the clutch is engaged, and torque is stably transmitted for a long time, the method of this embodiment introduces a second cleaning mode for the operating state of the transmission to achieve periodic cleaning of the target solenoid valve, maintain its performance stability, and avoid hydraulic system abnormalities caused by blockage.
[0081] The second cleaning mode is a cleaning strategy adapted to the operating state of the transmission, that is, when the vehicle adopts the second cleaning mode corresponding to the operating state of the transmission and is in a preset state, the target solenoid valve is controlled to be periodically cleaned according to the first preset mileage cycle. That is to say, when the vehicle adopts the second cleaning mode and is in a preset state (such as the gear state remains unchanged and the clutch is in the engaged state), by monitoring the actual driving mileage after the vehicle enters the preset state, and using the mileage as the reference basis for the cleaning cycle, the periodic cleaning of the target solenoid valve is realized. Specifically, through step 120, when the vehicle adopts the second cleaning mode corresponding to the operating state of the transmission, the preset cleaning cycle based on mileage corresponding to the preset second cleaning mode (denoted as the first preset mileage cycle) is determined; then, through step 220, when the actual driving mileage after the vehicle enters the preset state reaches an integer multiple of the first preset mileage cycle for the second cleaning mode, it is considered that the vehicle has been in the preset state for a long time, and the cleaning operation of the target solenoid valve is triggered. In this way, the first preset mileage cycle is used as the cleaning cycle of the target solenoid valve (that is, the target solenoid valve is cleaned once every first preset mileage cycle when the vehicle is in the preset state), without considering the influence of time and vehicle speed, that is, without real-time monitoring and calculation of the dynamic changes of the running time or vehicle speed after the vehicle enters the preset state, reducing the demand for complex computing resources and improving the response efficiency of the system; and using the actual driving mileage as the cleaning trigger condition can more directly reflect the running load of the vehicle and the actual usage state of the target solenoid valve, widely adapt to various running states of the vehicle, reduce the complexity of cleaning strategy adjustment, and ensure the accuracy of the cleaning operation trigger timing.
[0082] Moreover, during each cleaning, the target solenoid valve is controlled to switch on and off at a second preset frequency for a second preset number of times, so as to effectively clean the target solenoid valve when the vehicle is in a preset state. Among them, when foreign matters accumulate inside the target solenoid valve, by performing a rapid opening and closing operation on the solenoid valve (i.e., switching on and off at the second preset frequency for the second preset number of times), a pulsed flushing effect on the target solenoid valve is achieved, that is, the target solenoid valve is frequently opened and closed within a short period of time, so that the hydraulic oil forms a strong pulsating flow in the hydraulic system pipeline. This pulsation can enhance the impact force of the hydraulic oil fluid on the pollutants (foreign matters) at the target solenoid valve, and disturb the stubborn foreign matters attached to the pipeline wall and inside the target solenoid valve through the dynamic change of the fluid, so as to more effectively strip and carry them away, realizing the effective cleaning of the target solenoid valve. When the foreign matters are removed, the axial force of the target solenoid valve is enhanced, which can ensure that the target solenoid valve can work stably even under low-pressure conditions, allowing the low-pressure hydraulic oil to flow smoothly from the oil inlet to the oil outlet of the target solenoid valve, and ensuring the normal response of the target solenoid valve and the hydraulic system. Among them, the second preset frequency and the second preset number of times can be set according to actual needs. In some embodiments, the second preset frequency and the second preset number of times can be fixed values corresponding to the second cleaning mode, such as the second preset number of times being 8.
[0083] Optionally, when the actual driving mileage after the vehicle enters the preset state reaches an integer multiple of the first preset mileage period, step 200 further includes:
[0084] Adjust the hydraulic oil pressure at the target solenoid valve to the preset pressure upper limit value of the target solenoid valve.
[0085] To enhance the ability to remove foreign objects at the target solenoid valve, it is preferable to control the hydraulic oil pressure at the target solenoid valve to the preset pressure upper limit value of the target solenoid valve (which can be achieved through the cooperation of the oil pump of the hydraulic system and other solenoid valves) when cleaning the target solenoid valve. Specifically, when the vehicle is in the second cleaning mode and the actual driving mileage after the vehicle enters the preset state reaches an integer multiple of the first preset mileage cycle for the second cleaning mode, the second cleaning mode is triggered. In this mode, the hydraulic system of the vehicle transmission controls the hydraulic oil pressure at the target solenoid valve to be increased to the preset pressure upper limit value of the target solenoid valve, and controls the target solenoid valve to switch on and off at the second preset frequency for the second preset number of times under this preset pressure upper limit value, so as to achieve high-pressure cleaning and flushing of the target solenoid valve. Among them, through the action of the high-pressure liquid flow, the flow rate of the hydraulic oil in the narrow gap blocked by foreign objects at the target solenoid valve is significantly increased, and the physical peeling force of the hydraulic oil on the attached and accumulated foreign objects is increased, which can significantly improve the cleaning effect and ensure the comprehensive cleaning of the target solenoid valve and even the entire hydraulic system. Among them, the preset pressure upper limit value is set based on the rated pressure range of the target solenoid valve and the design parameters of the transmission hydraulic system, and the maximum pressure value that does not affect the response characteristics of the target solenoid valve and the operation state of the transmission (such as maintaining the stability of the preset state) is taken to achieve the best cleaning effect.
[0086] Optionally, as shown in Figure 1 、 Figure 4 Step 100 includes:
[0087] Step 130: When using the third cleaning mode corresponding to the total vehicle mileage, determine the corresponding second preset mileage cycle as the preset cleaning cycle according to the value of the total vehicle mileage;
[0088] Step 200 includes:
[0089] Step 230: Control the target solenoid valve of the hydraulic system to be cleaned periodically according to the second preset mileage cycle; among them, during each cleaning, control the target solenoid valve to switch on and off at the third preset frequency for the third preset number of times.
[0090] Considering that the life cycle of the vehicle gradually decreases as the total vehicle mileage increases, in order to ensure that the target solenoid valve can maintain a normal working state during the long-term operation of the vehicle, while maintaining the cleanliness of the hydraulic system, and thus maintaining the overall performance and reliability of the vehicle, a third cleaning mode for the total vehicle mileage is introduced. Based on the characteristics of the vehicle life cycle and taking the mileage as a reference basis, periodic cleaning of the target solenoid valve is realized, effectively reducing the solenoid valve blockage during the entire life cycle of the vehicle, and ensuring the normal response of the hydraulic system during the entire life cycle of the vehicle.
[0091] The third cleaning mode is a cleaning strategy adapted to the total vehicle mileage, that is, controlling the target solenoid valve to be periodically cleaned according to the second preset mileage period corresponding to the specific value of the total vehicle mileage. The second preset mileage period is a mileage interval value for cleaning the target solenoid valve determined according to the total vehicle mileage or the vehicle life cycle, and can be dynamically adjusted according to the change of the total vehicle mileage. Specifically, through step 130, when obtaining the current total vehicle mileage of the vehicle, the second preset mileage period for the third cleaning mode corresponding thereto can be determined according to the total vehicle mileage; subsequently, through step 230, the hydraulic system is controlled to operate in the third cleaning mode, that is, the second preset mileage period is used as the cleaning period of the target solenoid valve, and the target solenoid valve is periodically cleaned. For example, within the corresponding mileage range, every time the vehicle travels the second preset mileage period, the target solenoid valve is cleaned once. In this way, it is ensured that the cleaning frequency of the target solenoid valve matches the actual use situation of the vehicle, while timely removing impurities or foreign matters that may accumulate at the target solenoid valve due to the long-term operation of the hydraulic oil circulation, reducing the risk of blockage or performance degradation, and avoiding overly frequent cleaning operations, thereby reducing the additional burden on the hydraulic system and extending the service life of the target solenoid valve and the entire hydraulic system.
[0092] Moreover, during each cleaning, the target solenoid valve is controlled to switch the third preset number of times at the third preset frequency to achieve effective cleaning of the target solenoid valve. Among them, when foreign matters accumulate inside the target solenoid valve, by performing rapid opening and closing operations on the solenoid valve (that is, switching the third preset number of times at the third preset frequency), a pulsed flushing effect on the target solenoid valve is achieved, that is, the target solenoid valve is frequently opened and closed within a short time, so that a strong pulsating flow is formed in the hydraulic system pipeline by the hydraulic oil. This pulsation can enhance the impact force of the hydraulic oil fluid on the pollutants (foreign matters) at the target solenoid valve, and disturb the stubborn foreign matters attached to the pipeline wall and inside the target solenoid valve through the dynamic change of the fluid, so as to more effectively strip and carry them away, achieving effective cleaning of the target solenoid valve. After the foreign matters are removed, the axial force of the target solenoid valve is enhanced, which can ensure that the target solenoid valve can work stably even under low-pressure conditions, allowing the low-pressure hydraulic oil to flow smoothly from the oil inlet to the oil outlet of the target solenoid valve, and ensuring the normal response of the target solenoid valve and the hydraulic system. The third preset frequency and the third preset number of times can be set according to actual needs. In some embodiments, the third preset frequency and the third preset number of times can be fixed values corresponding to the third cleaning mode.
[0093] Optionally, the second preset mileage period includes a first preset mileage, a second preset mileage, and a third preset mileage, and both the first preset mileage and the third preset mileage are less than the second preset mileage;
[0094] Determining a corresponding second preset mileage period as the preset cleaning period according to the value of the total vehicle mileage includes:
[0095] When the value of the total vehicle mileage is greater than 0 and less than or equal to a third preset value, determine the first preset mileage as the preset cleaning period;
[0096] When the value of the total vehicle mileage is greater than the third preset value and less than or equal to a fourth preset value, determine the second preset mileage as the preset cleaning period;
[0097] When the value of the total vehicle mileage is greater than the fourth preset value, determine the third preset mileage as the preset cleaning period.
[0098] To adapt to the cleaning requirements of the target solenoid valve in different stages within the vehicle life cycle, the third cleaning mode introduces a dynamic cleaning period adjustment strategy based on the total vehicle mileage. By setting multiple different preset mileage ranges and their corresponding cleaning periods, the periodic cleaning of the target solenoid valve can be flexibly achieved.
[0099] Specifically, in the low-mileage stage, that is, when the value of the current total mileage of the vehicle is greater than 0 and less than or equal to the third preset value, the vehicle and its hydraulic system have been in use for a short time. To prevent the accumulation of initial foreign substances (such as those generated by the initial running-in of the corresponding components of the vehicle that has been in use for a short time) at the target solenoid valve, the preset cleaning cycle is determined to be the first preset mileage, so as to adopt a higher cleaning frequency (i.e., the reciprocal of the first preset mileage) to ensure the cleanliness of the target solenoid valve and the hydraulic system during the initial operation, effectively reduce solenoid valve blockage, and ensure the normal response of the hydraulic system. In the mid-mileage stage, that is, when the value of the current total mileage of the vehicle is greater than the third preset value and less than or equal to the fourth preset value, the vehicle has completed the initial running-in at this stage, and the amount of impurities generated in the hydraulic system is relatively stable and decreasing. Therefore, the cleaning requirement is reduced. At this time, the preset cleaning cycle is determined to be the second preset mileage, so as to adopt a lower cleaning frequency (i.e., the reciprocal of the second preset mileage), thereby reducing unnecessary cleaning operations while ensuring the normal cleanliness of the hydraulic system, improving the operating efficiency of the hydraulic system, and extending the service life of the target solenoid valve and the hydraulic system. In the high-mileage stage, that is, when the current total mileage of the vehicle is greater than the fourth preset value, the vehicle has entered the late stage of use. The components of the hydraulic system and the target solenoid valve may show a certain degree of aging, and the impurities generated during operation and the accumulated foreign substances increase. The cleaning requirement increases again. At this time, the preset cleaning cycle is determined to be the third preset mileage, so as to adopt a higher cleaning frequency (i.e., the reciprocal of the third preset mileage) to meet the cleaning requirement of the hydraulic system in the high-mileage stage, enhance the ability to remove the attached and accumulated foreign substances in the hydraulic system, and ensure the operating reliability of the target solenoid valve and the stability of the hydraulic system. In this way, by dynamically adjusting the cleaning cycle in stages during the vehicle life cycle, it is possible to accurately match the cleaning requirements of the hydraulic system in different mileage stages, avoiding both resource waste caused by too high a cleaning frequency and effectively solving the risk of system failures that may be caused by insufficient cleaning, thus providing strong guarantee for the long-term stable operation of the vehicle and its hydraulic system. Among them, the third preset value, the fourth preset value, the first preset mileage, the second preset mileage, and the third preset mileage can be set according to actual needs.
[0100] Exemplarily, the third preset value is taken as 20000 km, the fourth preset value is taken as 200000 km, the first preset mileage is taken as 50 km, the second preset mileage is taken as 200 km, and the third preset mileage is taken as 100 km. Then, when the total vehicle mileage is in the range of 0 to 20000 kilometers, the cleaning frequency of the target solenoid valve is to perform a flush every 50 kilometers to ensure the cleanliness of the target solenoid valve and the hydraulic system during the initial stage (low mileage stage); when the total vehicle mileage is in the range of 20000 to 200000 kilometers, the cleaning frequency of the target solenoid valve is to perform a flush every 200 kilometers to ensure the cleanliness of the solenoid valve in the mid - mileage stage and reduce the number of cleanings, thereby reducing the impact on the hydraulic system and the vehicle; when the total vehicle mileage is in the stage after 200000 kilometers (high mileage stage), due to the aging and wear of the vehicle, the solenoid valve may be more vulnerable to contamination. Therefore, in this stage, it is necessary to increase the cleaning frequency. For example, the cleaning frequency of the target solenoid valve is to perform a flush every 100 kilometers to ensure the cleanliness and normal operation of the solenoid valve. In some embodiments, the third preset number of times in different mileage stages is also different to adapt to the vehicle life cycle or the total vehicle mileage. For example, the third preset number of times corresponding to the low mileage stage is taken as 20, the third preset number of times corresponding to the mid - mileage stage is taken as 10, and the third preset number of times corresponding to the high mileage stage is taken as 20.
[0101] Optionally, the on - off control of the target solenoid valve is achieved by controlling the energized state of the electromagnet of the target solenoid valve.
[0102] Exemplarily, for a certain solenoid valve in the hydraulic system of a transmission, when the electromagnet coil of the solenoid valve is energized, an electromagnetic force will be generated, and the electromagnetic force is directly proportional to the current in the electromagnet coil; the electromagnetic force attracts or pushes the valve core to move against the resistance of the spring to open or close the valve passage of the solenoid valve, thereby realizing the adjustment of the output pressure of the solenoid valve. In some embodiments, because different particulate foreign matters may cause different degrees of jamming problems, for the target solenoid valve that opens the valve passage when energized, a longer energization time is suitable for dealing with large particulate foreign matters or severe blockages at the target solenoid valve, and the foreign matters are strongly impacted and cleared by increasing the flow rate and velocity of the fluid flowing through the target solenoid valve; while a shorter energization time is suitable for dealing with fine particulate foreign matters or slight jamming at the target solenoid valve, which can effectively remove the foreign matters and avoid wear caused by excessive flushing.
[0103] Optionally, in order to further improve the cleaning effect of the target solenoid valve in the hydraulic system, while cleaning is achieved by switching the target solenoid valve on and off according to a preset frequency and number of times, the oil pump in the hydraulic system can also be coordinated to ensure that the flow rate and pressure of the hydraulic oil used for cleaning the target solenoid valve meet the cleaning requirements.
[0104] Optionally, the target solenoid valve can be any one or more in the hydraulic system. In some embodiments, cleaning of the target solenoid valve in the hydraulic system may require the cooperation of other solenoid valves. For example, for a solenoid valve that is not directly connected to the oil pump through a pipeline, if the oil pump needs to provide hydraulic oil with corresponding flow rate and pressure for it, it is necessary to control the opening and closing of the corresponding solenoid valve located between the target solenoid valve and the oil pump to adjust the flow direction and oil pressure of the hydraulic oil in the hydraulic system, so that the hydraulic oil can be guided to the target solenoid valve to clean the target solenoid valve. It should be noted that when cleaning the corresponding target solenoid valve, it is necessary to ensure that it will not affect the normal operation of the hydraulic system and the vehicle; in some embodiments, it is also necessary to ensure that the cleaning of the corresponding target solenoid valve will not affect the current operating state of the hydraulic system and the vehicle.
[0105] Optionally, the hydraulic system includes a hydraulic oil filtering device.
[0106] In this embodiment, the hydraulic oil filtering device of the hydraulic system can be set at the inlet of the hydraulic system (such as the inlet of the fuel tank, the inlet of the oil pump, etc.), or set in the hydraulic system, to remove particulate impurities in the hydraulic oil and prevent them from continuing to flow in the hydraulic system and causing blockage or wear to the target solenoid valve and other key components in the hydraulic system, thereby extending the service life of the hydraulic system and ensuring the normal response of the hydraulic system.
[0107] Optionally, the vehicle response control method further includes:
[0108] When the target solenoid valve becomes blocked, actively clean the target solenoid valve;
[0109] Among them, actively cleaning the target solenoid valve includes: controlling the target solenoid valve to switch at a fourth preset frequency for a fourth preset number of times.
[0110] Specifically, different from the above-mentioned periodic cleaning of the target solenoid valve, it is also possible to actively detect the blockage of the target solenoid valve and, when the target solenoid valve is blocked, actively clean the target solenoid valve, so as to handle the situation when the target solenoid valve is blocked and ensure the normal response of the target solenoid valve and the hydraulic system. Among them, actively cleaning the target solenoid valve includes: controlling the target solenoid valve to switch at a fourth preset frequency for a fourth preset number of times. The fourth preset frequency and the fourth preset number of times can be set according to actual needs. In some embodiments, for the detection of the blockage of the target solenoid valve, a flow sensor can be configured in the hydraulic system to monitor the input and output hydraulic oil flow rates of the target solenoid valve. When the difference between the input and output hydraulic oil flow rates exceeds a preset threshold, it is determined that the target solenoid valve may be blocked; or, according to the response time of the target solenoid valve, such as the time delay between the input control signal (such as input current or voltage signal) and the feedback signal (such as the feedback signal about the actual displacement or switch state of the solenoid valve) of the target solenoid valve, if the time delay exceeds the corresponding preset threshold, it is determined that the target solenoid valve may be blocked.
[0111] Optionally, the vehicle response control method further includes:
[0112] If the current cleaning of the target solenoid valve conflicts with the operating state of the transmission, cancel or delay the current cleaning of the target solenoid valve.
[0113] To avoid affecting the normal operation of the transmission when cleaning the target solenoid valve, by real-time monitoring the operating state of the transmission, when the periodic cleaning operation corresponding to the preset cleaning mode may conflict with the current operating state of the transmission, the cleaning plan is dynamically adjusted to ensure the normal and stable operation of the transmission and the vehicle. Specifically, by reading the status signal of the transmission control unit (TCU), the key operating parameters of the current transmission are obtained, such as gear position, shift timing, hydraulic pressure demand, etc.; when a periodic cleaning operation needs to be performed, if the current cleaning of the target solenoid valve conflicts with the operating state of the transmission, such as when the transmission needs to perform operations such as shifting gears or changing the clutch state at this time, the operation of the transmission is given priority, and the current cleaning of the target solenoid valve is cancelled or delayed. Exemplarily, when the corresponding operation of the transmission is of high priority, the current cleaning plan of the target solenoid valve is cancelled, and the cleaning is performed next time (the hydraulic system still operates according to the preset cleaning mode corresponding to the operating parameters); or the current cleaning operation is delayed until after the transmission completes the corresponding operation, and this delay does not affect the periodic cleaning operations of other times in the preset cleaning mode.
[0114] Optionally, the vehicle response control method further includes:
[0115] When at least two of the first cleaning mode, the second cleaning mode, and the third cleaning mode are adopted simultaneously, if there are identical cleaning times for the target solenoid valve in the different preset cleaning modes adopted, then select one of the preset cleaning modes to clean the target solenoid valve at the identical cleaning time.
[0116] Specifically, considering that the preset cleaning mode is to clean the target solenoid valve periodically multiple times, when at least two of the first cleaning mode, the second cleaning mode, and the third cleaning mode are adopted simultaneously, there may be one or more identical cleaning times for the target solenoid valve in the different preset cleaning modes adopted. For example, the cleaning time of the target solenoid valve in a certain instance of the first cleaning mode is the same as that in a certain instance of the second cleaning mode. At this time, to avoid the occurrence of a conflict in the operation logic of the vehicle response control method, then select one from the preset cleaning modes corresponding to the identical cleaning time for cleaning the target solenoid valve at this cleaning time.
