Abstract: A method estimating weight of a motor vehicle including front and rear wheel assemblies using a smart communication device after loading the vehicle, including: (i) identifying the vehicle in the smart communication device; (ii) using a camera of the smart communication device, capturing and processing a photograph of at least one vehicle wheel after loading to determine displacement of a corresponding wheel assembly; (iii) using at least one accelerometer or inclinometer of the smart communication device, measuring at least one tilt angle of the vehicle after loading to determine displacement of the opposite wheel assembly and the corresponding wheel assembly; (iv) using a calculation unit of the smart communication device, calculating load values on the corresponding and opposite wheel assemblies based on respective displacements of the wheel assemblies, to determine a total load vehicle value; and (v) indicating by the smart communication device a vehicle load state to the user.

Abstract: A method for estimating the interval within which the total weight of an automobile vehicle is situated includes defining at least two intervals of weights, including determining a first situation in which the total weight of the vehicle belongs to the first interval and a second situation in which the total weight of the vehicle belongs to the second interval, calculating probabilities of being in the first or second situation knowing a value of the weight, calculating a risk of choosing the wrong interval as a function of the calculated probabilities and of a cost associated with an erroneous decision, and determining the interval within which the total weight of the vehicle is situated as a function of the risk.

Abstract: A diagnostic method for an a posteriori analysis of behavior of a vehicle braking system, the braking system including a regenerative braking mechanism, an additional braking mechanism, and a distribution device, the method including storing, in a non-volatile memory, at least one current value of a braking parameter from the distribution device for subsequent analysis based on the at least one value stored in the non-volatile memory, wherein the storage is triggered by execution of at least one event.
