Abstract

A vehicle and method for detecting the formation of ignitable mixtures in the closed spaces of the vehicle has at least one signal-generating sensor mounted in the closed spaces of the vehicle at a point at which, because of the physical characteristics of the fuel and because of the spatial conditions, harmful substances and/or gases collect first. The signals generated by the at least one sensor are processed in an electronic circuit which, as a function of the measured harmful-substance or gas concentration, actuated movable vehicle parts for closing and opening certain vehicle spaces.
