METHOD FOR DETECTING AN AMBIENT PRESSURE IN AN INTERNAL COMBUSTION ENGINE

摘要

The present invention relates to a method for detecting the ambient pressure (pamb) by means of a pressure sensor (40) in the intake pipe (50) of an internal combustion engine. According to the invention, the throttle flap (30) is opened so that the pressure drop via the throttle flap (pthrottle) can be neglected. The dethrottling of the internal combustion engine is compensated by the appropriate adjustment of the cam shaft in accordance with the operating state of the internal combustion engine, so that the measuring method is not being felt by the driver.
