The application relates to the technical field of vehicle control, and discloses a valve opening determination method, device, electronic device and storage medium. The method includes: determining a pulse pressure range based on current engine operating condition information and current outlet pipe pressure; The pulse pressure range and the pulse wave time information of the pulse period determine the pulse pressure at each moment in the pulse period; for any moment in the pulse period, determine the first pressure between the inlet pressure of the intercooler and the ambient pressure at the moment and determine the second pressure difference between the pulse pressure and the post-processing back pressure at the moment; opening at the stated time. This embodiment is based on the first pressure difference between the inlet pressure of the intercooler and the ambient pressure at the air release valve, the second pressure difference between the pulse pressure and the aftertreatment back pressure, and the air release parameters of the air release valve. Determine the real-time opening of the bleed valve.
Description
technical field [0001] The present application relates to the technical field of vehicle control, and in particular, to a method, device, electronic device and storage medium for determining a valve opening. Background technique [0002] The supercharger of some engines is equipped with a bleed valve. By adjusting the valve opening of the bleed valve and changing the amount of exhaust gas that works on the turbocharger turbine, parameters such as the speed of the supercharger and pumping loss can be adjusted to optimize fuel consumption. . [0003] The valve opening of the bleed valve will be adaptively adjusted with the engine operating conditions. The valve opening of the bleed valve is important for turbine operation evaluation (such as turbine operating area evaluation), engine performance evaluation, and engine control (such as engine intake air volume control), etc. It is of great significance, but there is no way to calculate the valve opening of the supercharger blo...
