Research on Active Collision Avoidance Strategy for Intelligent Vehicles under Dangerous Working Conditions
In order to effectively solve the problem of using a single braking collision avoidance control strate-gy to adapt to the collision avoidance needs of different emergency conditions in existing active collision avoidance systems,and improve the active safety of intelligent vehicles,this paper proposes an active collision avoidance strategy that combines braking and steering collision avoidance modes.Firstly,an emergency braking safety dis-tance model and an emergency turning safety distance model are established through kinematics.Then,the safe-ty benefit range of different collision avoidance modes is distinguished based on road adhesion coefficient and rela-tive speed.Finally,the intervention mode of the active collision avoidance strategy is determined.
