Problems solved by technology

[0007] One of the problems encountered is: the indicator collision time is uncertain, but safety must be ensured
However, in the case of early intervention, a high false alarm rate may occur
This high false alarm rate may be detrimental to driver acceptance of the system

Embodiment Construction

[0018] figure 1 A traffic scenario 1 is illustrated in which there is a risk of collision and in which the driver assistance system and method according to the invention are used.

[0019] In traffic scenario 1 , two vehicles 2 and 4 are approaching a two-way stop road intersection 5 between a first road 6 and a second road 8 . Vehicles on the second road 8 should stop at the intersection 5 according to the usual road marking symbols of the signs 10 , 12 as shown.

[0020] exist figure 1 In the scenario of , it is assumed that vehicle 2 is the host vehicle including the driving assistance system, also referred to as the ego vehicle. The vehicle 4 is another vehicle within a predetermined vicinity of the vehicle 2, referred to as another vehicle or a nearby vehicle.

[0021] figure 1 The situation represented in is a normal traffic situation considering that both vehicles 2 and 4 have straight trajectories on their respective roads, however, multiple scenarios at intersecti...

Abstract

The invention concerns a method of driving assistance for assisting a human driver in safely driving a vehicle called host vehicle, implemented by a processor on board of said host vehicle. The host vehicle comprises means for obtaining first information relative to the host vehicle and means for obtaining second information relative to at least one other vehicle in a neighborhood of the host vehicle, said first and second information being obtained at regular time instants, comprising triggering an intervention of a collision avoidance system. The method comprises a step (51) of intervention decision adapted to decide whether to trigger the intervention of the collision avoidance system at a current time instant (Tc) or to postpone said intervention decision at a later time instant (Tl) depending upon additional first and second information to be acquired between the current time instant (Tc) and the later time instant (Tl), said additional first and second information having an associated probability. The invention also concerns an associated system of driving assistance.

Description

technical field [0001] The present invention relates to a driving assistance method for assisting a driver in safely driving a vehicle called a host vehicle and implemented by an on-board processor of the host vehicle, and a related driving assistance system. [0002] The field of the invention is that of active safety systems implemented in vehicles. Background technique [0003] There is always a need to improve road safety and prevent traffic accidents. Currently, vehicles such as private cars are equipped with various sensors which, when used in conjunction with road map databases, allow obtaining first information about the vehicle's position and the position of its movements. Furthermore, the vehicle may be equipped with additional sensors that provide second information about other vehicles driving on adjacent roads (referred to as neighboring vehicles). Such additional sensors include laser locators, radars and cameras. Alternatively, the vehicle may be adapted to...
