摘要:
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.

The invention relates to a vehicle control device comprising: —means (10, 20, 30) for generating various control modes dependent on parameters concerned with the way in which the vehicle is moving such as, rotational speed of the wheels, yaw rate, lateral acceleration and longitudinal acceleration, pressure on the brake controls exerted by the driver, and a vehicle life situation mode chosen by the driver from various preestablished life situations corresponding to different types of road and terrain and different vehicle rolling conditions, —estimating means (40) for estimating the vehicle life situation, the device being configured to determine an optimum control mode (32, 34, 36, 38) from among the various control modes that can be generated by the device as a function of the estimated vehicle life situation and the life situation mode chosen by the driver.
摘要:
A braking process to increase the stability of a vehicle taking a bend while the driver is braking in which the activation of the brakes of the rear wheels is decoupled from depression of the pedal, the process including: detecting an entry condition including a bend test and a braking test; and, while the entry condition is verified, determining a base braking force from the depression of the brake pedal; correcting the base force to obtain a corrected force smaller than the base force; modulating the corrected force to obtain a reference force smaller than the corrected force; and applying the corrected braking force to the outside rear wheel and the reference braking force to the inside rear wheel.
摘要:
A process for braking a vehicle provided with brake calipers which can be activated as a function of a target braking force, at least the activation of the brake calipers of the rear wheels being decoupled from depression of a brake pedal, including: detecting a logical entry condition including at least a deceleration test verified when an instantaneous value of the deceleration of the vehicle is greater than a threshold deceleration; calculating of a rear base braking force by correcting the braking force required by the driver so that the rear base braking force is greater than the front base braking force; and applying the rear base braking force as target braking force for the rear wheels, so that the pitching motion of the vehicle is reduced on deceleration.
