Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle damping, in particular to a continuous damping control method, an electronic device and a readable storage medium. BACKGROUND

[0002] The continuous damping control shock absorber is a continuously adjustable damping shock absorber. The electronic control unit (ECU) receives information from sensors, CAN (Controller Area Network) and driver inputs, comprehensively processes the information and outputs instructions to dynamically adjust the damping force of the shock absorber, thereby improving the vehicle handling stability and driving smoothness. For a vehicle equipped with a built-in continuous damping control shock absorber of a semi-active suspension, the vehicle can increase the vehicle driving stability by controlling the damping force of the continuous damping control shock absorber. The working principle is that the suspension controller changes the throttle area by controlling the opening degree of the electromagnetic valve of the continuous damping control shock absorber to change the flow rate of the oil in the working chamber, thereby controlling the damping force of the continuous damping control shock absorber, so that the vehicle can maintain a stable body posture on a bumpy road. However, due to the viscous effect of the oil in the continuous damping control shock absorber, there are air bubbles in the oil. When the continuous damping control shock absorber moves, the air bubbles pass through the electromagnetic valve of the continuous damping control shock absorber under the push of the piston, causing abnormal noise. Especially when the vehicle is parked for a long time in winter, when the vehicle starts, the continuous damping control shock absorber moves slightly, and the high-viscosity oil passes through the electromagnetic valve of the continuous damping control shock absorber, causing abnormal noise in the continuous damping control shock absorber.

In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples, without contradiction with each other.

[0038] The core idea of the present application is to provide a continuous damping adjustable shock absorber control method, electronic equipment and readable storage medium. By current flushing of the electromagnetic valve of the continuous damping adjustable shock absorber, the internal abnormal sound problem of the continuous damping adjustable shock absorber can be effectively solved, and the occurrence of the working abnormal sound problem of the continuous damping adjustable shock absorber after long time stagnation is prevented.

[0039] It should be noted that the continuous damping adjustable shock absorber control method provided by the application can be applied to the electronic device provided by the application, and the electronic device can be a hardware device with various operating systems. The electronic device provided by the application can be used as a suspension controller and applied to a vehicle equipped with a continuous damping adjustable shock absorber. The vehicle can include general motor vehicles, such as passenger vehicles including sports utility vehicles (SUVs), buses, trucks, various commercial vehicles, and hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, etc. In addition, it should be noted that, as understood by those skilled in the art, the continuous damping adjustable shock absorber control method provided by the application can not only solve the internal abnormal noise problem of the semi-active suspension built-in continuous damping adjustable shock absorber, but also solve the internal abnormal noise problem of the semi-active suspension external continuous damping adjustable shock absorber.

[0040] To achieve the above idea, the application provides a continuous damping adjustable shock absorber control method, please refer to Figure 1 , which is a flowchart of the continuous damping adjustable shock absorber control method provided by an embodiment of the application. As shown in Figure 1 , the continuous damping adjustable shock absorber control method provided by the application includes the following steps:

[0041] Step S100, determine whether the working condition of the continuous damping adjustable shock absorber meets the preset shock absorber abnormal noise occurrence condition.

[0042] If the result of the determination is that the working condition of the continuous damping adjustable shock absorber meets the preset shock absorber abnormal noise occurrence condition, then step S200 is executed to determine whether the vehicle is in a powered-on state.

[0043] If the result of the determination is that the vehicle is in a powered-on state, then step S300 is executed to determine whether the solenoid valve of the continuous damping adjustable shock absorber is in a fault state.

[0044] If the result of the determination is that the solenoid valve of the continuous damping adjustable shock absorber is in a fault state, then step S400 is executed to perform a current flushing control strategy on the solenoid valve of the continuous damping adjustable shock absorber.

[0045] Therefore, the continuous damping adjustable shock absorber control method provided by the application can make the valve core of the electromagnetic valve of the continuous damping adjustable shock absorber vibrate, thereby effectively reducing the bubbles in the oil of the continuous damping adjustable shock absorber and reducing the viscosity of the oil of the continuous damping adjustable shock absorber, and further effectively solving the internal abnormal sound problem of the continuous damping adjustable shock absorber and preventing the occurrence of the working abnormal sound problem of the continuous damping adjustable shock absorber.

[0046] It should be noted that, as understood by those skilled in the art, if the result of step S100 is that the working condition of the continuous damping adjustable shock absorber does not meet the preset shock absorber abnormal sound occurrence condition, the subsequent steps S200-S400 do not need to be performed, that is, the current flushing control strategy for the electromagnetic valve of the continuous damping adjustable shock absorber does not need to be performed. Similarly, if the result of step S200 is that the vehicle is in a powered-off state, the subsequent steps S300-S400 do not need to be performed, that is, the current flushing control strategy for the electromagnetic valve of the continuous damping adjustable shock absorber does not need to be performed. If the result of step S300 is that the electromagnetic valve of the continuous damping adjustable shock absorber is in a fault state, the current flushing control strategy for the electromagnetic valve of the continuous damping adjustable shock absorber does not need to be performed.

[0047] In some exemplary embodiments, the preset shock absorber abnormal sound occurrence condition includes that the continuous damping adjustable shock absorber has been in a stationary state for longer than a preset time length and / or the ambient temperature of the continuous damping adjustable shock absorber is lower than a preset temperature threshold. Since bubbles in the oil of the shock absorber may occur when the shock absorber is stationary for a long time, the viscosity of the shock absorber oil is too high, and the temperature of the shock absorber oil is too low, thereby causing the working abnormal sound of the shock absorber. Therefore, by performing the current flushing control strategy for the electromagnetic valve of the continuous damping adjustable shock absorber when the working condition of the continuous damping adjustable shock absorber meets the condition that the continuous damping adjustable shock absorber has been in a stationary state for longer than a preset time length and / or the ambient temperature of the continuous damping adjustable shock absorber is lower than a preset temperature threshold, and the vehicle is in a powered-on state and the electromagnetic valve of the continuous damping adjustable shock absorber has no fault, the bubbles in the oil of the continuous damping adjustable shock absorber can be effectively reduced, and the viscosity of the oil of the continuous damping adjustable shock absorber can be reduced, thereby effectively solving the internal abnormal sound problem of the continuous damping adjustable shock absorber and preventing the occurrence of the working abnormal sound problem of the continuous damping adjustable shock absorber.

[0048] In some exemplary embodiments, the current flushing control strategy for the electromagnetic valve of the continuous damping adjustable shock absorber includes:

[0049] According to the obtained flushing current, the target flushing time and the flushing period, the electromagnetic valve of the continuously variable damper is subjected to current flushing.

[0050] Therefore, by periodically subjecting the electromagnetic valve of the continuously variable damper to current flushing according to the obtained flushing current, the target flushing time and the flushing period, the electromagnetic valve of the continuously variable damper can be controlled to be subjected to current flushing at the natural frequency, so that the spool of the electromagnetic valve of the continuously variable damper can be periodically fluttered, thereby effectively reducing the bubbles in the oil of the continuously variable damper and reducing the viscosity of the oil of the continuously variable damper, so as to effectively solve the internal abnormal sound problem of the continuously variable damper and prevent the occurrence of the working abnormal sound problem of the continuously variable damper.

[0051] In some exemplary embodiments, the target flushing time is obtained according to the ambient temperature of the vehicle and a function relationship between the pre-obtained flushing time and the ambient temperature.

[0052] Since the lower the ambient temperature of the vehicle, the greater the viscosity of the damper oil, and the greater the possibility of generating bubbles in the damper oil, by determining the target flushing time according to the ambient temperature of the vehicle and the function relationship between the pre-obtained flushing time and the ambient temperature, it can not only avoid that the internal abnormal sound problem of the continuously variable damper cannot be effectively solved due to too short current flushing time, but also avoid affecting the service life of the electromagnetic valve of the continuously variable damper due to too long current flushing time.

[0053] Specifically, the target flushing time T can be calculated according to the following formula:

[0054] T = f1(x1)

[0055] Wherein, f1 represents the function relationship between the flushing time and the ambient temperature, and x1 represents the ambient temperature of the vehicle.

[0056] It should be noted that the function relationship f1 between the flushing time and the ambient temperature can be simulated by damper bench test as understood by those skilled in the art.

[0057] In some exemplary embodiments, the current flushing of the electromagnetic valve of the continuously variable damper according to the obtained flushing current, the target flushing time and the flushing period comprises:

[0058] According to the obtained flushing current, the target flushing time and the flushing period, the electromagnetic valve of the continuously variable damper is subjected to sinusoidal current flushing.

[0059] Therefore, by applying a sinusoidal current to the solenoid valve of the continuously damped adjustable vibration damper based on the obtained flushing current, target flushing time, and flushing cycle, it can be ensured that the solenoid valve of the continuously damped adjustable vibration damper can periodically and gradually open and close during the flushing process. This not only effectively reduces air bubbles in the oil of the continuously damped adjustable vibration damper and lowers the viscosity of the oil, thus solving the internal abnormal noise problem of the continuously damped adjustable vibration damper and preventing the occurrence of abnormal noise during operation, but also avoids the impact of frequent flushing on the service life of the solenoid valve of the continuously damped adjustable vibration damper.

[0060] In some exemplary implementations, the flushing current is obtained through the following steps:

[0061] The scouring current amplitude is obtained based on the target scouring time, the scouring cycle, and the maximum operating current of the solenoid valve of the continuously damped adjustable vibration damper.

[0062] Based on the scouring current amplitude, the scouring period, and the preset sine function, the scouring current corresponding to each scouring moment within a single scouring period is obtained.

[0063] Therefore, by determining the flushing current amplitude based on the target flushing time, the flushing cycle, and the maximum operating current of the solenoid valve of the continuously damped adjustable damper, it is possible to effectively ensure that air bubbles in the oil can be smoothly discharged during the flushing process, thus guaranteeing the flushing effect.

[0064] Specifically, the scouring current amplitude I can be calculated using the following formula. amp :

[0065] I amp =I max *(T pd / T)

[0066] Among them, I max T represents the maximum operating current of the solenoid valve of the continuously damped adjustable vibration damper. pd This indicates the flushing cycle, and T represents the target flushing time.

[0067] Furthermore, the scouring current corresponding to each scouring moment within a single scouring cycle can be calculated using the following formula:

[0068] I set =f3(I amp, T pd )

[0069] Among them, I set f3 represents the flushing current at a specific flushing moment within a single flushing cycle, and I represents the preset sine function. ampdenotes the amplitude of the flushing current, T pd denotes the flushing period.

[0070] In some exemplary embodiments, the current flushing control strategy performed on the solenoid valve of the continuously variable damper further comprises:

[0071] acquiring an actual flushing time;

[0072] determining whether the actual flushing time is equal to the target flushing time;

[0073] if yes, stopping the current flushing on the solenoid valve of the continuously variable damper.

[0074] Therefore, by acquiring the actual flushing time and stopping the current flushing on the solenoid valve of the continuously variable damper when the actual flushing time is equal to the target flushing time, the internal abnormal sound problem of the continuously variable damper can be effectively solved without too short flushing time, and the service life of the solenoid valve of the continuously variable damper can be avoided from being affected by too long flushing time.

[0075] Further, the actual flushing time can be calculated according to the flushing times and the flushing period. It should be noted that, as understood by those skilled in the art, the current flushing completing one complete flushing period is one flushing.

[0076] Specifically, the actual flushing time can be calculated according to the following formula:

[0077] T flush = T pd * Step

[0078] wherein, T pd denotes the flushing period, and Step denotes the flushing times.

[0079] In some exemplary embodiments, the continuously variable damper control method provided by the present application further comprises:

[0080] if the solenoid valve of the continuously variable damper is in a fault state, a limp control strategy is performed on the continuously variable damper.

[0081] Therefore, by performing the limp control strategy on the continuously variable damper when the solenoid valve of the continuously variable damper is in a fault state, i.e. not performing the current flushing on the solenoid valve of the continuously variable damper, the invalid flushing can be effectively avoided.

[0082] The overall flow of the continuously variable damper control method provided by the present application will be described below. Figure 2 .Figure 2 which is the overall flowchart of the continuous damping adjustable shock absorber control method provided by an embodiment of the present application. As shown in Figure 2 , the continuous damping adjustable shock absorber control method provided by the present application specifically comprises the following steps:

[0083] 1) First, it is judged whether the working condition of the continuous damping adjustable shock absorber meets the preset shock absorber abnormal sound occurrence condition. If the working condition of the continuous damping adjustable shock absorber does not meet the preset shock absorber abnormal sound occurrence condition, the current flushing control strategy is not executed.

[0084] 2) If the working condition of the continuous damping adjustable shock absorber meets the preset shock absorber abnormal sound occurrence condition, it is judged whether the vehicle is in the powered-on state. If the vehicle is in the powered-off state, the current flushing control strategy is not executed.

[0085] 3) If the vehicle is in the powered-on state, it is judged whether the electromagnetic valve of the continuous damping adjustable shock absorber is in the fault state. If the electromagnetic valve of the continuous damping adjustable shock absorber is in the fault state, the continuous damping adjustable shock absorber executes the limp-home control strategy.

[0086] 4) If the electromagnetic valve of the continuous damping adjustable shock absorber is not in the fault state, the flushing current amplitude, the target flushing time and the flushing period are calculated, and the calculation is based on factors such as the ambient temperature. After the flushing current amplitude, the target flushing time and the flushing period are calculated, the sinusoidal current flushing of the electromagnetic valve of the continuous damping adjustable shock absorber is performed. At the same time, the actual flushing time is monitored. When the actual flushing time reaches the target flushing time, the sinusoidal current flushing program is exited, and the flushing is ended.

[0090] Further, the memory 103 can be used to store the computer program, and the processor 101 realizes various functions of the electronic device by running or executing the computer program stored in the memory 103 and calling the data stored in the memory 103. The memory 103 can include non-volatile and / or volatile memory.

Since the readable storage medium provided by the application and the continuous damping adjustable shock absorber control method provided by the application belong to the same inventive concept, the readable storage medium provided by the application at least has all the beneficial effects of the continuous damping adjustable shock absorber control method provided by the application, and the specific beneficial effects of the readable storage medium provided by the application can be referred to the related description of the beneficial effects of the continuous damping adjustable shock absorber control method provided by the application, and thus the beneficial effects of the readable storage medium provided by the application will not be repeated here.

[0092] The readable storage medium provided by the present application can adopt any combination of one or more computer-readable media. The readable medium can be a computer-readable signal medium or a computer-readable storage medium. The computer-readable storage medium may, for example, but is not limited to, an electrical, magnetic, optical, electromagnetic, infrared or semiconductor system, device or instrument, or any combination of the above.

The program code contained on the computer-readable medium can be transmitted by any suitable medium, including but not limited to wireless, wire, optical cable, RF, etc., or any suitable combination thereof.

[0094] In summary, compared with the prior art, the continuous damping adjustable shock absorber control method, electronic device and readable storage medium provided by the present application have the following beneficial effects:

[0095] The application first determines whether the working condition of the continuously variable damping shock absorber meets the preset shock absorber abnormal sound occurrence condition, and when it is determined that the working condition of the shock absorber meets the preset shock absorber abnormal sound occurrence condition, it is determined whether the vehicle is in a powered-on state, and then when it is determined that the vehicle is in the powered-on state, it is further determined whether the solenoid valve of the continuously variable damping shock absorber is in a fault state, and when it is determined that the solenoid valve of the continuously variable damping shock absorber is not in the fault state, the current flushing control strategy is performed on the solenoid valve of the continuously variable damping shock absorber. Thus, by flushing the current of the solenoid valve of the continuously variable damping shock absorber when the working condition of the continuously variable damping shock absorber meets the preset shock absorber abnormal sound occurrence condition, the vehicle is in the powered-on state, and the solenoid valve of the continuously variable damping shock absorber is not in the fault state, the spool of the solenoid valve of the continuously variable damping shock absorber can be vibrated, thereby effectively reducing the bubbles in the oil of the continuously variable damping shock absorber and reducing the viscosity of the oil of the continuously variable damping shock absorber, and the internal abnormal sound problem of the continuously variable damping shock absorber can be effectively solved, and the occurrence of the working abnormal sound problem of the continuously variable damping shock absorber can be prevented.

[0096] In addition, by performing the current flushing control strategy on the solenoid valve of the continuously variable damping shock absorber when the working condition of the continuously variable damping shock absorber meets the condition that the stop duration of the continuously variable damping shock absorber is greater than the preset duration and / or the ambient temperature of the continuously variable damping shock absorber is lower than the preset temperature threshold, and the vehicle is in the powered-on state and the solenoid valve of the continuously variable damping shock absorber is not in the fault state, the bubbles in the oil of the continuously variable damping shock absorber can be effectively reduced, and the viscosity of the oil of the continuously variable damping shock absorber can be reduced, thereby the internal abnormal sound problem of the continuously variable damping shock absorber can be effectively solved, and the occurrence of the working abnormal sound problem of the continuously variable damping shock absorber can be prevented.

[0097] Further, by periodically flushing the current of the solenoid valve of the continuously variable damping shock absorber according to the obtained flushing current, target flushing time and flushing period, the solenoid valve of the continuously variable damping shock absorber can be controlled to flush the current at the inherent frequency, so that the spool of the solenoid valve of the continuously variable damping shock absorber can be periodically vibrated, thereby the bubbles in the oil of the continuously variable damping shock absorber can be effectively reduced, and the viscosity of the oil of the continuously variable damping shock absorber can be reduced, so that the internal abnormal sound problem of the continuously variable damping shock absorber can be effectively solved, and the occurrence of the working abnormal sound problem of the continuously variable damping shock absorber can be prevented.
