Abstract
Description
Technical Field
[0001] The present invention relates to the field of vehicle control, and particularly to a power interruption control method, device, equipment and storage medium. Background Art
[0002] For traditional double-rear-axle drive vehicles, both drive axles output driving forces during the vehicle's no-load and full-load transportation processes. With the development of power interruption technology, combined with the lifting mechanism of the air suspension, double-rear-axle power interruption vehicles have been developed. The working principle of its structure is as follows: when the vehicle is fully loaded, the power interruption vehicle and the conventional double-rear-axle drive vehicle both output driving forces from the two axles. When the vehicle is unloaded, the lifting function button on the instrument panel or the ECAS (Electronic Control Air Suspension System) system remote control can be pressed to use the ECAS system to lift the rear axle, making the rear axle wheels leave the ground. At the same time, the power interruption control mechanism arranged between the middle and rear axles is used to cut off the power input from the middle axle to the rear axle, so that the vehicle becomes a single-axle output driving force. This technology can reduce fuel consumption and reduce rear axle tire wear, and is currently a hot spot in the development of suspension systems.
[0003] At present, the application of power interruption technology requires the use of the lifting mechanism of the air suspension, so it is only applicable to vehicles equipped with air suspension and not applicable to leaf spring suspension. At the same time, manual control is required during the change of the drive form. It is easy to judge which drive form should be adopted for no-load and full-load, but it is not easy to judge which drive form should be adopted when the vehicle is lightly loaded, that is, when there is cargo on the vehicle but it is not fully loaded. Moreover, in the prior art, the engine torque limit is not jointly controlled after the rear axle is lifted. The engine is configured with power according to the double-axle drive. When the vehicle becomes a single-axle drive, that is, in the state where the rear axle is lifted, all the output power of the engine is transmitted to a single axle, resulting in too much power output of the engine to a single axle, which will cause increased wear inside the axle and even premature damage to the axle after long-term use.
[0004] Therefore, there is an urgent need for a power interruption control method that can be applied to any double-rear-axle drive vehicle and can adaptively judge the drive mode of the vehicle. Summary of the Invention
[0005] The present invention provides a power interruption control method, device, equipment and storage medium to solve the technical problem in the prior art that the drive mode of the vehicle cannot be adaptively judged.
[0006] To solve the above technical problem, an embodiment of the present invention provides a power interruption control method, including:
[0007] Obtain the axle load message of the vehicle, and based on the axle load message, obtain the current middle axle load;
[0008] Obtain the interruption status information message of the vehicle, and based on the interruption status information message, obtain the current driving mode of the vehicle, and determine whether the mid-bridge axle load is within the preset axle load range corresponding to the current driving mode;
[0009] If so, there is no need to adjust the power interruption of the vehicle; if not, switch the driving mode of the vehicle, and based on the preset control rules corresponding to the switched driving mode, adjust the power interruption of the vehicle; wherein, the driving mode includes single-bridge drive and double-bridge drive.
[0010] It can be understood that the present invention determines whether the mid-bridge axle load of the vehicle is within the axle load range under the current driving mode by obtaining the mid-bridge axle load of the vehicle and the current driving mode of the vehicle, that is, judging based on the load weight of the vehicle, thus avoiding the problem that it is not easy to judge whether the driving mode of the vehicle needs to be adjusted in the case of a lightly loaded vehicle. At the same time, it can further improve the accuracy of the transformation of the vehicle driving mode, and when the mid-bridge axle load is not within the axle load range under the actual driving mode, adjust the power interruption of the vehicle, so as to accurately and automatically transform the vehicle driving mode, and then realize the adjustment of the power interruption, and is applicable to any double-bridge drive vehicle including leaf spring suspension and air suspension.
[0011] As a preferred solution, before obtaining the axle load message of the vehicle and based on the axle load message, obtaining the current mid-bridge axle load, it further includes:
[0012] Obtain and analyze the status of the vehicle's key socket;
[0013] When it is detected that the key is in the ignition position, obtain the axle load message of the vehicle; wherein, the axle load message is generated by the mid-bridge weighing system.
[0014] It can be understood that by obtaining and analyzing the status of the key socket, the present invention can obtain the axle load message generated by the mid-bridge weighing system of the vehicle when it is monitored that the key is in the ignition position, that is, start obtaining the axle load message only after each engine start, which can avoid the difference in the vehicle axle load due to different slopes, speeds and accelerations of the vehicle, improve the accuracy and reliability of the axle load message, and can also avoid potential safety hazards during vehicle driving during adjustment.
[0015] As a preferred solution, before obtaining the interruption status information message of the vehicle and based on the interruption status information message, obtaining the actual driving mode of the current vehicle, it further includes:
[0016] Calculate the absolute value of the difference between the mid-bridge axle load and the preset reference value, and determine whether the absolute value is greater than the preset limit value;
[0017] If so, obtain the interruption status information message of the vehicle; if not, maintain the current status of the vehicle.
[0018] It can be understood that the setting of the preset reference value and the preset limit value can be based on the possible axle load size errors when the vehicle is on different ground slopes. Therefore, by calculating the absolute value of the difference between the middle axle load and the preset reference value and comparing this absolute value with the preset limit value, it is possible to avoid misjudgment and misoperation of the adaptive drive mode caused by axle load errors due to ground slope factors, thereby improving the accuracy of vehicle drive mode judgment.

[0021] It can be understood that when the vehicle switches the drive mode, since different drive modes correspond to different states of the inter-axle differential and the torque of the engine, it is also necessary to adjust the state of the inter-axle differential and the output of the engine torque. This can not only reduce the input of engine fuel and lower fuel consumption, but also alleviate the problem of mismatch of different drive modes under the same torque output of the engine, thereby protecting the axle and improving the service life of the axle.

[0025] The adjustment module is configured to, if the mid-bridge axle load is within the preset axle load range corresponding to the current driving mode, no adjustment for power interruption of the vehicle is required; if the mid-bridge axle load is not within the preset axle load range corresponding to the current driving mode, switch the driving mode of the vehicle, and perform adjustment for power interruption of the vehicle according to the preset control rule corresponding to the switched driving mode; wherein, the driving modes include single-bridge drive and double-bridge drive.
[0026] As a preferred solution, the embodiment of the present invention further includes: a detection module;

[0028] As a preferred solution, the embodiment of the present invention further includes: a second judgment module;
[0029] The second judgment module is configured to calculate the absolute value of the difference between the mid-bridge axle load and a preset reference value, and judge whether the absolute value is greater than a preset limit value;
[0030] If so, obtain the interruption status information message of the vehicle; if not, maintain the current state of the vehicle.
[0031] As a preferred solution, the adjustment module is configured to switch the driving mode of the vehicle, and perform adjustment for power interruption of the vehicle according to the preset control rule corresponding to the switched driving mode, specifically:
[0032] Control the power interruption solenoid valve of the vehicle, so that the power interruption solenoid valve switches the driving mode of the vehicle, and adjusts the state of the inter-axle differential and the output of the engine torque according to the preset control rule corresponding to the switched driving mode, thereby completing the adjustment for power interruption of the vehicle.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.
[0040] Embodiment 1
[0041] Please refer to Figure 1 , a power interruption control method provided by an embodiment of the present invention, includes the following steps S1 - S3:
[0042] S1: Obtain the axle load message of the vehicle, and based on the axle load message, obtain the current middle axle load.
[0043] As a preferred solution of this embodiment, please refer to Figure 2 , before the step of obtaining the axle load message of the vehicle and based on the axle load message, obtaining the current middle axle load, it further includes steps S11 - S12:
[0044] S11: Obtain and parse the key socket state of the vehicle.
[0045] S12: When it is detected that the key is in the ignition position, obtain the axle load message of the vehicle; wherein, the axle load message is generated by the middle axle weighing system.
[0046] In this embodiment, after the secondary engine starts, it starts to detect whether the driving mode needs to be adjusted, rather than detecting after the axle load changes. At the same time, the axle load of the vehicle varies due to different ground slopes, speeds, and accelerations. Therefore, during the driving process of the vehicle, the axle load will change. If the detection is carried out only after the axle load changes, there will be a situation of misjudgment operation, resulting in inaccurate power interruption control of the vehicle.
[0047] It should be noted that the axle load message includes, but is not limited to, information such as the front axle load, middle axle load, and rear axle load of the vehicle, which is obtained through the middle axle weighing system or the ECAS system in the vehicle.
[0048] It can be understood that by obtaining and analyzing the state of the key socket, the present invention can obtain the axle load message generated by the middle axle weighing system of the vehicle when it is detected that the key is in the ignition position, that is, start obtaining the axle load message only after each engine start. This can avoid the difference in vehicle axle load due to different slopes, speeds, and accelerations of the vehicle, improve the accuracy and credibility of the axle load message, and also avoid potential safety hazards during vehicle driving when adjusting.
[0049] S2: Obtain the interruption status information message of the vehicle, and based on the interruption status information message, obtain the current driving mode of the vehicle, and determine whether the middle axle load is within the preset axle load range corresponding to the current driving mode.
[0050] It should be noted that the interruption status information message of the vehicle is obtained through the power interruptor. The interruption status information message includes, but is not limited to, information such as the current driving mode of the vehicle and the opening and closing status of the power interruption solenoid valve. The preset axle load range is set according to the actual vehicle operation conditions. At the same time, by judging whether the middle axle load is within the preset axle load range corresponding to the current driving mode, the problem that it is not easy to manually judge which driving mode to adopt when the vehicle is not fully loaded can be effectively solved.
[0051] As a preferred solution of this embodiment, please refer to Figure 3 , before obtaining the interruption status information message of the vehicle and based on the interruption status information message, obtaining the actual driving mode of the current vehicle, the following steps S21 - S22 are also included:
[0052] S21: Calculate the absolute value of the difference between the middle axle load and the preset reference value, and determine whether the absolute value is greater than the preset limit value.
[0053] S22: If so, obtain the interruption status information message of the vehicle; if not, maintain the current state of the vehicle.
[0054] It should be noted that the preset reference value is determined according to the load weight of the vehicle, that is, the standard axle load of the vehicle corresponding to the current load weight. The preset limit value can be set according to the actual vehicle driving conditions. Exemplarily, if the standard axle load of the vehicle is obtained as 10t according to the current load weight of the vehicle, then the current preset reference value G 0 = 10t, and the middle axle load G i = 11t of the current vehicle is obtained according to the obtained axle load message, and the preset limit value G 2If it is 0.5t, then the absolute value of the difference between the medium bridge axle load and the preset reference value is 1t, which is greater than the preset limit value of 0.5t. Therefore, it is necessary to obtain the interruption status information message of the vehicle to further adjust the current state of the vehicle. This step can accurately judge the influence of external factors (such as ground slope, etc.) on the change of vehicle axle load, and can well eliminate the change of axle load caused by external factors, so as to generate axle load error and cause misjudgment and misoperation of the adaptive system.
[0055] It can be understood that the setting of the preset reference value and the preset limit value can be based on the possible axle load size error when the vehicle is on different ground slopes. Therefore, by calculating the absolute value of the difference between the medium bridge axle load and the preset reference value and comparing this absolute value with the preset limit value, the axle load error caused by the ground slope factor can be eliminated, so as to avoid misjudgment and misoperation of the adaptive driving mode, and further improve the accuracy of vehicle driving mode judgment.
[0056] S3: If so, there is no need to adjust the power interruption of the vehicle; if not, switch the driving mode of the vehicle, and adjust the power interruption of the vehicle according to the preset control rules corresponding to the switched driving mode; wherein, the driving mode includes single-bridge drive and double-bridge drive.
[0057] As a preferred solution, the switching of the driving mode of the vehicle and the adjustment of the power interruption of the vehicle according to the preset control rules corresponding to the switched driving mode are specifically as follows:
[0058] Control the power interruption solenoid valve of the vehicle to make the power interruption solenoid valve switch the driving mode of the vehicle, and adjust the state of the inter-axle differential and the output of the engine torque according to the preset control rules corresponding to the switched driving mode, so as to complete the adjustment of the power interruption of the vehicle.
[0059] In this embodiment, before adjusting the power interruption, the vehicle status is also displayed on the vehicle instrument and sound and light prompts are issued, etc. After the adjustment of the power interruption is completed, the information that the vehicle is ready is displayed on the vehicle instrument. Further, different driving modes have different preset control rules. For example, when switching to single-bridge drive, the number of output shafts is reduced, the state of the inter-axle differential arranged on the medium bridge is adjusted, and the torque output of the engine is reduced.
[0060] Exemplarily, when the vehicle is switched from dual-axle drive to single-axle drive, the rear axle does not need to be lifted and only follows, without generating driving force, so as to reduce power output and power transmission loss, thereby reducing energy consumption. At the same time, torque limit control is performed on the engine, which can reduce the fuel input of the engine, further reduce fuel consumption, and avoid configuring the power of the engine according to dual-axle drive. When the existing vehicle is in the state of single-axle drive, the output power of the engine is all transmitted to a single axle, so long-term use will lead to increased wear inside the axle and even premature damage to the axle. However, the embodiment of the present invention can avoid the occurrence of the above problems by controlling the torque limit of the engine.
[0061] It can be understood that when the vehicle switches the driving mode, since different driving modes correspond to different states of the inter-axle differential and the torque of the engine, it is also necessary to adjust the state of the inter-axle differential and the output of the engine torque. This can not only reduce the fuel input of the engine and lower fuel consumption, but also alleviate the problem of mismatch of different driving modes under the torque output of the same engine, thereby protecting the axle and increasing the service life of the axle.
[0062] Implementing the embodiment of the present invention has the following effects:
[0063] In the embodiment of the present invention, by re-entering the ignition position with the key to trigger and obtain the axle load of the middle axle of the vehicle and the current driving mode of the vehicle, it is judged whether the axle load of the middle axle of the vehicle is within the axle load range under the current driving mode, that is, judged by the load weight of the vehicle, so as to avoid the problem that it is not easy to judge whether the driving mode of the vehicle needs to be adjusted when the vehicle is lightly loaded. And the setting of the preset reference value and the preset limit value can well eliminate the change of the axle load caused by external factors, so as to generate an axle load error and cause misjudgment and misoperation of the adaptive system. At the same time, it can further improve the accuracy of the vehicle driving mode transformation. When the axle load of the middle axle is not within the axle load range under the actual driving mode, the vehicle is adjusted for power interruption, so that the vehicle driving mode can be accurately and automatically changed, and then the adjustment of power interruption can be realized. It can also alleviate the problem of mismatch of different driving modes under the torque output of the same engine, thereby protecting the axle and increasing the service life of the axle. And this embodiment can be applied to any dual-axle drive vehicle including leaf spring suspension and air suspension.
