Abstract

A driver assistance system of a vehicle includes: at least one ultrasonic sensor for ascertaining the distance of the vehicle from an obstacle, the sensor being supplied with electrical energy by an onboard electrical system of the vehicle; and an undervoltage detector for detecting an undervoltage in the onboard electrical system, in the event of which the power requirement of the ultrasonic sensor is reduced.
