Pressure acquisition chain calibrating system for motor vehicle, has determination unit calculating offset value with respect to reference pressure values and values of signals delivered by cylinder pressure sensor

摘要

The system has a unit (66) modifying values of conditioning parameters in a pressure acquisition chain (28) according to values of the conditioning parameters that are determined by an information processing unit (34). A determination unit (62) calculates offset value (P offset) with respect to reference pressure values (P 0) and values of signals delivered by a cylinder pressure sensor (30).
