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 applied.

[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 interse...

Abstract

The present application relates to a driving assistance method for assisting a driver in safely driving a vehicle called a host vehicle, and the method is implemented by an on-board processor of the host vehicle. The host vehicle includes means for obtaining first information related to the host vehicle and means for obtaining second information about at least one other vehicle in the vicinity of the host vehicle, the first information and the The second information is obtained at a specified time, and the method includes triggering an intervention of a collision avoidance system. The method comprises an intervention decision step (51) adapted to decide, on the basis of additional first information and additional second information to be obtained between the current instant (Tc) and the subsequent instant (Tl), whether to intervene at The current moment (Tc) triggers the intervention of the collision avoidance system, or delays the intervention decision until the later moment (Tl), the additional first information and the additional second information have associated probability distributions . The invention also relates to a related driver assistance system.

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...
