A method for checking the plausibility of at least one in an electronic control unit of a control device controlled signal value

摘要

A method for checking the plausibility of at least one in an electronic control unit of a control device controlled signal value, including the steps of:a) performing a plausibility check (p1) by the control unit by means of checking whether the signal value within or outside a predetermined interval is,b) if, in accordance with a positive plausibility check (p1) of the signal value within the predetermined interval, is at least one of the signal value associated function of the control device is carried out without restriction,c) if, in accordance with a negative plausibility check (p1) of the signal value lies outside of the predetermined time interval, the control unit in the initial state (reset) is reset and again carried out a plausibility check (p2),d) if, in accordance with a positive renewed plausibility check (p2) of the signal value within the predetermined interval, is at least one of the signal value associated function of the control device is carried out without restriction,e) if, in accordance with a negative renewed plausibility check (p2) of the signal value lies outside of the predetermined time interval, a plausibility error signal is produced and / or at least the the signal value associated function of the control device..
