Assistance system for driving in slopes for automobiles
First Claim
1. An assistance system for driving a motor vehicle in slopes, wherein the system comprisessensors for continuous measurements of physical quantities related to the movement of the vehicle,an electronic path-correcting computer named ESP computer integrating a hill assist module for uphill starting assistance and a hill descent control module for limiting downhill speed, andactuators controlled by the ESP computer in order to act on different driving parameters of the vehicle,wherein the computer further integrates a hill assist descent control module for assistance with control of driveability in slopes which orders the entry into action and withdrawal of either one of said hill assist and hill descent control modules for handling intermediate life situations of the vehicle between situations managed by the hill assist module and those managed by the hill descent control module,wherein the hill assist descent control module controls (i) when the vehicle is starting on an uphill slope and when the vehicle is starting on a downhill slope, entry into action of the hill assist module for starting assistance, (ii) gradual withdrawal from operation of the hill assist module after an operating time of the hill assist module longer than a predetermined duration, and (iii) the vehicle then being in movement, entry into action of the hill descent control module if the speed of the vehicle is higher than a predetermined speed on a downhill slope, so as to slow down the vehicle to this predetermined speed.

Abstract
The system of the invention includes sensors (11, 12, 13) for measuring physical values useful for driving assistance, a path correction electronic calculator (20) including a Hill Assist (HA) module for hill start assistance and a Hill Descent Control module for limiting the downhill speed, and actuators (31 to 35) 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.
