Abstract: The invention relates to a strut rod made of composite material for a suspension of a front axle of a vehicle, including: an upper part coupled to a rod and piston assembly connected to a vehicle body; and a U-shaped lower part including two brackets for fixing a knuckle arm of the vehicle. This strut rod includes means for detecting a crack. This detection means includes at least one additional edge positioned so as to project from an outer surface of the U-shaped lower part of the strut rod in a region where a crack possibly occurs in the case of an accidental shock on a wheel of the vehicle.

Abstract: A shock absorber mounted on a vehicle includes an inner portion that is made of a metal and has a first upper end and a first lower end, and an outer portion that is made of a composite material and is integrally formed with the inner portion. The outer portion has at least one of a second upper end on which the first upper end of the inner portion is folded and a second lower end on which the first lower end of the inner portion is folded, and a middle portion that has a seat for supporting a suspension spring.

Abstract: The invention relates to a system for controlling the state and operation of a motor vehicle. The system is characterized in comprising sensors (C1, C2, . . . and CN) arranged on the vehicle and a control unit (35), receiving information from the different sensors and determining the state of the vehicle from said information and calculating the settings for braking transmitted to the dynamic (6) and static (7) breaking units, particularly allowing the vehicle to be maintained stationary when the speed thereof is zero. The invention finds application in the field of automobiles.
