Problems solved by technology

This mode of operation does not take into account the driver's desire to reduce the speed of the host vehicle to the end of the deceleration phase, for example because he wants to continue overtaking during the bend in question. speed thoughts
Moreover, this mode of operation may cause a slowing of the traffic flow which may be incomprehensible to at least one of the vehicle drivers following the slowed vehicle, even when one of these drivers does not The slowdown may prove dangerous when noted, especially when the slowdown is too weak to generate a signal

Embodiment Construction

[0025] The object of the present invention is, inter alia, to provide a speed regulation method and an associated speed regulation device DR for allowing regulation especially in the presence of bends The velocity of the vehicle V driving at least partially automatically (or autonomously).

[0026] In the following, as a non-limiting example, the vehicle V is considered to be of the motorized type. The vehicle is for example a car, such as figure 1 shown above. However, the invention is not limited to this type of vehicle. The present invention relates in fact to any type of land vehicle which is driven at least partially automatically and which can travel on a land traffic lane.

[0027] exist figure 1 The road R is schematically and functionally shown on the road, which includes a first traffic lane VC1 and a second traffic lane VC2, and two vehicles V' and V are respectively in the first traffic lane and the second traffic lane. Traffic on the traffic lane. The first ...

Abstract

A method is intended to regulate the speed of an at least partially self-driving vehicle, knowing the radius of curvature of a future position it is preparing to adopt on a course along which it is travelling. This method comprises a step (10-90) in which the speed is regulated as a function of a speed setpoint and, if a radius of curvature of the future position representative of a bend is detected, a phase of deceleration down to a chosen speed followed by a phase of acceleration until the speed setpoint is obtained are imposed on the vehicle. In this step (10-90), when the driver imposes acceleration on his vehicle during the deceleration phase, this deceleration phase is halted and then another phase of acceleration until the speed setpoint is obtained is imposed on the vehicle.

Description

technical field [0001] The invention relates to vehicles driven at least partially automatically, and more precisely to the regulation of the speed of such vehicles. [0002] In the following, when a vehicle is driven automatically (i.e. partially or fully (without driver intervention)) during an automated driving phase, or when manually (and thus accompanied by the driver of said vehicle at the steering wheel) during a manual driving phase and / or intervention on the pedals), the vehicle is considered to be driven at least partially automatically (or autonomously). Background technique [0003] Some vehicles driven at least partially automatically comprise regulating means responsible for regulating the speed of the vehicle according to a speed setpoint, optionally selected by the driver of the vehicle. [0004] Vehicles are traveling on the traffic lane, in some cases the adjustment device is able to adapt the speed of said vehicle according to the radius of curvature of t...
