Method for determining the plausibility of pressure signals, comprises successive stages which detect if a value is outside admissible limits or the rate of change exceeds the maximum rate of climb

摘要

The signals produced by a pressure sensor mounted in a vehicle are captured (101) and individually tested (102) against admissible limits. If the limits are exceeded an error is registered (103). The rate of change of the signals is then determined (104) and if it exceeds (105) the maximum rate of climb/descent of the vehicle an error is registered (106) and if not the cycle is repeated (107) : An independent claim is also included for a vehicle equipped with pressure sensor and microprocessor able to implement the stages for checking plausibility.
