Abstract

A warning system and a warning method for a motor vehicle having a high-voltage battery. The warning system includes a battery housing having the high-voltage battery, an underride protection device, a spatially closed cavity, at least one pressure sensor, and an evaluation device. The spatially closed cavity is arranged in a vertical direction of the warning system above the underride protection device and below the battery housing and is designed to change a volume of the cavity upon a deformation of the underride protection device under the action of a predetermined external force on the underride protection device. The at least one pressure sensor is designed to detect a pressure change value that describes a change in pressure in the pressure in the cavity.
