SYSTEM FOR ACTIVATING SAFETY MEASURES IN A MOTOR VEHICLE AND VEHICLE

System for activating safety measures in a motor vehicle comprising at least two acceleration sensors, namely at least one first sensor (201) and at least one second sensor (202) connected to a controller module configured to activate at least one vehicle security system upon detection of the signals wherein: the at least one first sensor (201) is configured to be arranged at a first vehicle front-end portion element and the at least one second sensor (202) is configured to be arranged at a second vehicle front-end portion element, the rigidity of the first vehicle front-end portion element being greater than the rigidity of the second vehicle front-end portion element, and; the controller module is configured to determine whether there is a mutual approximation or a mutual separation of the at least one first sensor (201) and the at least one second sensor (202).
