Problems solved by technology

[0003] The sensitivity of the existing advanced driving assistance systems when predicting the potential collision of the vehicle usually depends on the sensitivity threshold for predicting potential collisions manually set by the driver; After setting the sensitivity for predicting potential collisions, it is difficult to actively change the sensitivity setting during actual driving. Therefore, in the face of complex driving environments, the ADAS only uses the fixed sensitivity set by the driver. Threshold to predict potential collisions, which may not meet the safety requirements of driving

Embodiment Construction

[0074] In related technologies, an ADAS (Advanced Driver Assistant System, Advanced Driver Assistance System) system can usually be divided into different subsystems according to specific functions to be realized.

[0075] For example, the functions that can be realized by ADAS system can usually include: automatic braking, adaptive cruise control, lane departure warning, lane keeping replication, collision prediction, collision warning or collision mitigation and other functions. Therefore, the architecture of the ADAS system can include AEB (Autonomous Emergency Braking, autonomous emergency braking) system, ACC (Autonomous Emergency Braking, adaptive cruise control) system, LDW (Lane Departure Warning, lane departure warning) system, LKA (Lane Keeping Aid , lane keeping assist) system, collision prediction system, collision warning system or collision mitigation system and other subsystems corresponding to the above functions that need to be realized.

[0076] Among them, t...

Abstract

The invention provides a method for pre-judging vehicle collision. The method includes detecting dangerous driving behavior for vehicles; increasing collision time threshold values set by drivers until the collision time threshold values reach set safety values in response to the detected dangerous driving behavior; pre-judging vehicle collision on the basis of the increased collision time threshold values. The method has the advantages that the collision pre-judging sensitivity can be improved by the aid of the method under the condition that driving scenes of the dangerous driving behavior are detected, and accordingly the driving safety can be effectively enhanced.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method and system for predicting vehicle collisions. Background technique [0002] With the development of the automobile industry, the application of advanced driver assistance systems (ADAS) in automobiles has become more and more extensive. The advanced driver assistance system uses various sensors installed on the vehicle, such as on-board radar sensors, to sense the driving environment in real time during the driving process of the vehicle, collect data, and identify, detect and track static and dynamic objects, thereby Let the driver be aware of the impending collision in advance, effectively increasing the safety of driving. [0003] The sensitivity of the existing advanced driving assistance systems when predicting the potential collision of the vehicle usually depends on the sensitivity threshold for predicting potential collisions manually set by the driver; After s...
