The invention relates to a method for adjusting the driveability of at least one wheel of a vehicle, in particular an automobile, that comprises a wheel driving engine (), engine control means (), means () for supplying information on an acceleration level desired by the vehicle driver, means () for providing information on the vehicle acceleration level, and an electronic control unit including computing means () for receiving the different information. The computing means () are adapted in order to obtain a vehicle acceleration level that corresponds to the acceleration level desired by the driver. The device further includes means for providing information on the vehicle inclination.

Device and method for adjusting the driveability of an automobile

The system of the invention includes sensors () for measuring physical values useful for driving assistance, a path correction electronic calculator () including a Hill Assist (HA) module for hill start assistance and a Hill Descent Control module for limiting the downhill speed, and actuators (to) controlled by said calculator for acting on the different driving parameters. The calculator further includes a Hill Assist Descent Control (HADC) for driveability control assistance in slopes, that enables or disables the Hill Assist (HA) and Hill Descent Control (HDC) modules based on specific control rules for managing intermediate life situations between the situations managed by the Hill Assist (HA) module and those managed by the Hill Descent Control (HDC) module. The invention also relates to automobiles and to automobile driving assistance systems.

Assistance system for driving in slopes for automobiles

An anti-skid device for the driving wheels () of a vehicle, in particular an automotive vehicle, includes an active braking device () of the torque to be transmitted to the driving wheels; a torque regulator () providing a control signal (Cb) to the active braking device () according to information on the regulation deviations (&#x394;v) relative to a set predetermined regulation; a control unit () providing the regulator () with regulation initialization information (In). The control unit () obtains the regulation initialization information (In) from evolution parameters of the vehicle on all terrains, such as the adhesion and the speed of the driving wheels, the slope and/or slant of the terrain. Application: anti-skid device for the wheels of an automotive vehicle.
