Method and system for monitoring the boost pressure of an internal combustion engine of a motor vehicle

摘要

The system has a calculation module (CALC1) to calculate an absolute value of the difference between a set pressure and an inlet pressure (Padm) of gas of an internal combustion engine. A calculation module (CALC2) calculates a difference (Ex) between the absolute value and a preset pressure. An integration module (INT1) calculates a summation of ratio of maximum between the difference (Ex) and zero to the set pressure. The inlet pressure (Padm) of the gas of the internal combustion engine is determined by a module (DC) e.g. pressure sensor and pressure estimator. An independent claim is also included for a process of monitoring the boost pressure of an internal combustion engine of a motor vehicle.
