The present paper presents a methodology of automatic control for hybrid suspension, that is, which combines a pneumatic structure (air) and a mechanic one (spring). In addition, the work in question also aims to present an on-board scale to estimate the net cargo transported. As a technique, to approach the solution of both proposals mentioned, it is intended to use sensory fusion: signals available on the truck as well as signals from additional sensors. It is important to be noted that this paper proposal is dedicated for trucks equipped with tipper body. Nowadays, most of the times, the hybrid suspension control is given by manual means: the driver controls the pressure in the air bellows, according to the amount of load the vehicle is carrying on through a button on the instrument panel. This means that, if the truck is loaded, the air bellows of the pneumatic suspension must be full and, otherwise, when the truck is unloaded, the air bellows of the pneumatic suspension must be empty. The hybrid suspension control, when manual, results in a series of problems because the task of controlling is exclusively on driver hands and one might make mistakes during operation. The automatic control of the hybrid suspension is proposed, withdrawing the responsibility of the driver in this stage of the operation. Through sensorial fusion of signals available in the truck CAN network, signals from the tipper and additional sensors, it is intended to identify if the truck is loaded or not to act in the filling or emptying the air bellows, according to the operation needs. And, when the loading pattern is identified, in addition to the density of the carried material, it is also possible to estimate the net load of the truck, another detail also contemplated on this paper proposal.
