Abstract
A method for triggering a passenger protection unit of a vehicle includes: reading in a first and a second sensor signal value of a first sensor, which is situated at a first location in the vehicle; reading in a third and a fourth sensor signal value of a second sensor, which is situated at a second location in the vehicle which is different from the first location; and activating the passenger protection unit using the first, second, third and fourth sensor signal values. The first and third sensor signal values represent a physical variable detected in a first sensor direction, and the second and fourth sensor signal values represent a second physical value detected in a second sensor direction which is different from the first sensor direction.
