Description

Technical Field

[0001] This disclosure relates to the field of vehicle control technology, and in particular to a steering pump control system, method, apparatus and electronic equipment for noise reduction. Background Technology

[0002] The vehicle's steering pump circuit is the core hydraulic circulation path in a hydraulic power steering system or an electro-hydraulic power steering system. Its main function is to convert the mechanical energy of the engine (or electric motor) into hydraulic energy and deliver high-pressure oil to the steering actuator, thereby providing steering assistance to the driver.

[0003] When the vehicle's power steering pump circuit is operating, the oil temperature in the pipeline will rise accordingly, from 78℃ to 128℃. Normally, no abnormal noise will be generated when the oil temperature is below 90℃. However, when the oil temperature exceeds 90℃, air bubbles will form in the pipeline, causing abnormal noise in the power steering pump circuit. Therefore, a technical solution to this abnormal noise problem is urgently needed. Summary of the Invention

[0004] In view of this, the purpose of this disclosure is to provide a steering pump control system, method, apparatus and electronic equipment for noise reduction, which can specifically solve existing problems.

[0005] Based on the above objectives, in a first aspect, this disclosure proposes a steering pump control system for noise reduction, the system comprising: an oil temperature sensor connected to the vehicle's steering pump circuit and ECU, for detecting the oil temperature in the pipeline of the steering pump circuit; and a vacuum pump connected to the pipeline of the steering pump circuit, for discharging gas from the pipeline.

[0006] Secondly, a steering pump control method for noise reduction is also provided, employing the system described in the first aspect; the method includes: detecting the current engine speed of the vehicle; and determining whether to activate the vacuum pump based on whether the engine speed has reached a preset mid-speed value.

[0007] Thirdly, an electronic device is also provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, the processor running the computer program to implement the method of the first aspect.

[0008] Fourthly, a computer-readable storage medium is also provided, on which a computer program is stored, the computer program being executed by a processor to implement the method described in any one of the first aspects.

[0009] Fifthly, a computer program product is also provided, comprising a computer program that is executed by a processor to implement the method described in any one of the first aspects.

[0010] In summary, this disclosure has at least the following beneficial effects: by detecting the oil temperature of the steering pump circuit through an oil temperature sensor to determine whether the current steering pump circuit needs noise reduction, and by using a vacuum pump to extract gas to achieve noise reduction.

Detailed Implementation

[0013] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Figure 1A power steering pump control system for noise reduction according to this disclosure is shown. In embodiments of this disclosure, the system includes: an oil temperature sensor connected (directly or indirectly) to the vehicle's power steering pump circuit and ECU, for detecting the oil temperature in the pipelines of the power steering pump circuit; and a vacuum pump connected to the pipelines of the power steering pump circuit, for venting gas from the pipelines.

[0016] The working circuit of the steering pump circuit is: steering pump → steering cylinder → oil reservoir → steering pump.

[0017] This embodiment can detect the oil temperature of the steering pump circuit using an oil temperature sensor to determine whether the current steering pump circuit needs noise reduction, and use a vacuum pump to extract gas to achieve noise reduction.

[0018] In some optional implementations of any embodiment of this disclosure, the system further includes: a valve disposed between the pipeline and the vacuum pump, which can open or close the connection between the vacuum pump and the pipeline.

[0019] The valve can be a ball valve or other pipeline valves.

[0020] These methods can be implemented by adjusting the gas discharge pipeline through valves, such as by adjusting the opening degree, to control the gas output speed and ensure the stability of the steering pump circuit.

[0021] In some optional implementations of any embodiment of this disclosure, the steering pump circuit includes a steering pump, a steering cylinder, and an oil reservoir; the oil temperature sensor is connected to a target pipeline in the steering pump circuit, and the target pipeline is the connecting pipeline between the steering pump and the steering cylinder.

[0022] These methods can use oil temperature sensors to detect target pipelines close to the steering pump, thereby improving the accuracy of steering pump circuit detection.

[0023] Figure 2 A steering pump control method for noise reduction according to an embodiment of this disclosure is shown. Figure 2 As shown, the steering pump control method for noise reduction includes: employing the system as described in claim 1; the method includes: detecting the current engine speed of the vehicle; and determining whether to activate the vacuum pump based on whether the engine speed has reached a preset mid-speed value.

[0024] The system can determine whether to activate the vacuum pump using various methods. For example, the engine speed can be input into a preset model (such as a formula or a deep neural network) to obtain information on whether the vacuum pump is activated, output from the preset model.

[0025] Mid-range RPM refers to the engine's current speed, which is no longer below low RPM. For example, a mid-range RPM could be 2000 rpm.

[0026] This embodiment can detect the engine speed to determine whether the vacuum pump is turned on, and thus, based on the engine speed, gas can be discharged when the engine speed has reached a certain level and there may be bubbles in the steering pump circuit.

[0027] In some optional implementations of this embodiment, determining whether to turn on the vacuum pump based on whether the engine speed reaches a preset mid-speed value includes: if the engine speed reaches the preset mid-speed value, determining whether the temperature detected by the oil temperature sensor is greater than a preset temperature; if the temperature detected by the oil temperature sensor is greater than the preset temperature, starting the vacuum pump to discharge the gas in the pipeline through the vacuum pump.

[0028] These implementation methods can use a preset temperature as a condition for whether exhaust is needed, thereby enabling more accurate judgment on the necessity of exhaust.

[0029] Optionally, the system further includes a valve disposed between the pipeline and the vacuum pump, which can open or close the connection between the vacuum pump and the pipeline; the method further includes: if the temperature detected by the oil temperature sensor is greater than the preset temperature, then the valve is opened.

[0030] These optional implementations can open the valve at higher temperatures, avoiding the unnecessary opening of the valve due to temperature angle.

[0031] Specifically, the method further includes: if the temperature detected by the oil temperature sensor is not greater than the preset temperature, then closing the valve and controlling the vacuum pump to be in a stopped state.

[0032] like Figure 3a As shown, the steering system in this application consists of 1. a steering pump, 2. a steering cylinder, 3. an oil reservoir, 4. a vacuum pump, a pipeline oil temperature sensor T, and a ball valve Q.

[0033] like Figure 3b As shown, under normal conditions, the engine speed n is detected, and the ECU determines n. ≤ At a preset speed of 2000 rpm, ball valve Q is closed, and vacuum pump 4 is not working; the working circuit is: steering pump 1 → steering cylinder 2 → oil reservoir 3 → steering pump 1.

[0034] In abnormal conditions, the engine speed n is detected. If n > 2000 rpm, the oil temperature sensor T detects the oil temperature T. If the ECU determines that T > 90℃, the ball valve Q opens (preset time t is 5 minutes), and the vacuum pump 4 operates, increasing the airflow: air bubbles in the pipeline are expelled to the atmosphere via the vacuum pump 4. When the preset time t > 5 minutes, the ball valve Q closes, and the vacuum pump 4 stops. The working circuit returns to the normal circuit: steering pump 1 → steering cylinder 2 → oil reservoir 3 → steering pump 1.
