Abstract

A method for monitoring the signal value of a vacuum sensor of a vacuum system in a vehicle, wherein a vacuum generator and a brake booster are provided in the vacuum system, an upper error threshold (−p_vac_errorthreshold) is calculated as a function of the operating states of the vacuum generator and of the brake booster, and wherein an error is identified when the signal value of the vacuum sensor exceeds the current value of the error threshold.
