Description

Exhaust method and device of hydraulic lash adjuster in vehicle, electronic equipment and vehicle Technical Field The embodiment of the application relates to the technical field of vehicle control, in particular to an exhaust method and device of a hydraulic clearance regulator in a vehicle, electronic equipment and the vehicle. Background Currently, engine designs in vehicles rely on natural exhaust mechanisms, i.e., through oil flow and pressure fluctuations during normal engine operation, to allow air trapped inside the hydraulic lash adjusters to escape slowly after prolonged operation. In the related art, a simple exhaust valve or an air ventilation structure is often arranged in an oil pan or an oil way, but the structures do not have intelligent judging capability and can not dynamically trigger the exhaust action according to the actual working condition. Further, by detecting a decrease in the oil level of the engine oil (for example, the oil level) or an abnormality in the vehicle turning acceleration, it is indirectly estimated that air may be mixed in the engine oil, but only in a stage where it is determined that air is present, the exhaust gas execution operation or operation flow is not further set, and the exhaust gas trigger logic in cooperation with the engine operation state is not established. In summary, the timing of the exhaust is improper, or forced exhaust affects the power output under high load working conditions, or false triggering is caused when the exhaust is not needed, so that energy waste is caused. Therefore, there is still a technical problem that the performance of the pressure lash adjuster is degraded. Disclosure of Invention The embodiment of the application provides an exhaust method and device of a hydraulic lash adjuster in a vehicle, electronic equipment and the vehicle, and aims to solve the technical problem of performance degradation of the hydraulic lash adjuster. According to one embodiment of the application, a method for exhausting a hydraulic lash adjuster in a vehicle is provided, and the method can comprise the steps of determining the oil level of engine oil stored in an oil pan of the vehicle, determining a spatial inclination angle of the vehicle in response to the oil level being lower than a height threshold value and a maximum inclination angle threshold value allowed by an engine in the vehicle at a current rotating speed, wherein the spatial inclination angle is used for representing the inclination state of a vehicle body relative to the engine, acquiring the speed of the vehicle in response to the spatial inclination angle being smaller than or equal to the maximum inclination angle threshold value, adjusting the rotating speed of the engine based on the speed and the current rotating speed, and utilizing the adjusted rotating speed to control the hydraulic lash adjuster in the engine to exhaust internal gas. The above-described alternative embodiments of the present application can achieve the advantageous effect of determining the spatial inclination angle of the vehicle and the maximum inclination angle threshold allowed for the engine in the vehicle at the current rotational speed by determining the oil level height of the oil stored in the oil pan in the vehicle, in case the oil level height is below the height threshold. Under the condition that the spatial inclination angle is smaller than or equal to the maximum inclination angle threshold value, the speed of the vehicle is obtained, so that the rotating speed of the engine is adjusted based on the speed and the current rotating speed, and the hydraulic lash adjuster in the engine is controlled to discharge internal gas. Through the steps, four key information of oil level height, dynamic inclination angle of the vehicle, vehicle speed and rotating speed of the engine are logically coupled, and when the oil level is low and the spatial inclination angle of the vehicle does not exceed the safe running limit of the engine, whether the engine has an exhaust condition is further judged. And then, when the vehicle speed and the rotating speed indicate the current working condition without high power requirement, the exhaust condition can be confirmed to be met, the rotating speed of the engine can be actively increased to a controllable interval, and the sufficient time is maintained to form stable oil flow disturbance, so that the gas is caused to be safely discharged from the inside of the hydraulic lash adjuster, the technical problem of performance reduction of the hydraulic lash adjuster is solved, and the technical effect of improving the performance of the hydraulic lash adjuster is realized. Optionally, determining the spatial inclination angle of the vehicle and the maximum inclination angle threshold allowed by the engine in the vehicle at the current rotation speed in response to the oil level being lower than the height threshold comprises increasing the count number of the coun
