Abstract:
1. A system for controlling the operation of presence detection devices in a motor vehicle, which comprises in combination: a) external presence detection means for detecting the entry of objects in a certain observation area outside said vehicle; b) at least one power supply for supplying at least said external presence detection means; c) an electronic system including at least means for processing and analyzing first input signals obtained by said external presence detection means and which produces first output signals according to the result of said analysis; d) condition detection means of at least one closing device of at least one door of said automobile, associated and cooperating with said electronic system; e) internal presence detection means, which are associated with and cooperate with said electronic system to control said power supply, according to a presence or absence of people inside the vehicle; and f) tilt detection means, which are associated with and cooperate with said condition detection means of at said least one closing device of at said least one vehicle door and said internal presence detection means, to produce second input signals for said electronic system, according to the vehicle's tilt with respect to a plane of the ground on which said vehicle is standing, conditioned by various circumstances such as load, presence of passengers or braking, based on said tilt detection means, wherein said tilt detection means are associated with and cooperate with said electronic system, when the vehicle starts to move or once it has stopped, to vary the area of observation to be covered by said external presence detection means, according to the vehicle's tilt with respect to the plane of the ground on which said vehicle is standing, and said power supply is controlled by said electronic system, according to the opening and closing sequence of at least said closing device of said door, of which there is at least one, of said vehicle, obtained by said condition detection means.
