Problems solved by technology

Therefore, if the driver wants to reactivate creep, this is limited, for example, to requesting the brake pedal again, which may prove illogical and even potentially dangerous in some situations (eg on sloped roads or while manoeuvring)

Embodiment Construction

[0028] The object of the present invention is in particular to provide a control method and an associated control device D for controlling the creep of an automated vehicle V comprising a power system, a brake pedal and an accelerator pedal .

[0029] In the following, as a non-limiting example, the automated vehicle V is considered to be motorized. The automated vehicle is, for example, a passenger car. But the invention is not limited to this type of automated vehicle. In fact, the invention relates to all types of land automated vehicles provided with a power system comprising, on the one hand, at least one internal combustion engine MT and / or at least one (electric, hydraulic or compressed air) coupled to energy storage means The auxiliary engine (or electric machine), on the other hand, includes a component steering system responsible for automatically adapting the reduction gear of the powertrain to the wheels, or does not require a steering system of this type. Accor...

Abstract

A device (D) for controlling a "creep" mode of a vehicle (V) capable of causing the vehicle (V) to ) moves at a low speed. Said means (D) comprise control means (MC) configured to analyze, when said mode is activated, immediately after actuating the brake pedal for a first duration less than a selected first threshold a parameter value representing the current speed of the vehicle (V), and when the analyzed value remains less than a selected second threshold value during a selected second time period, said control means is configured to, immediately after said first The deactivation of the mode is triggered after a selected second time period after the time period.

Description

technical field [0001] The present invention relates to so-called automated vehicles, and more precisely to the control of so-called "rampante" (rampage) modes in such vehicles. Background technique [0002] An "automated vehicle" is understood here as a vehicle comprising a component manipulation system capable of adapting the reduction gears of the drivetrain (or GMP) of the vehicle to the wheels in an automatic manner (for example via a gearbox); An "automated vehicle" is also understood as a vehicle that does not require this type of control system (for example a vehicle with a purely electric powertrain). Therefore, the present invention particularly relates to vehicles with purely electric powertrains, vehicles with hybrid powertrains, and vehicles with automatic mechanisms including reduction gears (such as automatic manual gearboxes, dual-clutch gearboxes, automatic gearboxes or continuously variable gearboxes) powertrain of the vehicle. [0003] Furthermore, "cree...
