The invention discloses a vehicle transverse control exit algorithm strategy, relates to the technical field of intelligent driving, and solves the problem that a transverse control system in an auxiliary driving system of an existing vehicle is difficult to judge whether to directly exit or not according to real-time driving conditions; and when the middle transverse control exits, the safety is relatively low. Comprising the steps that when a transverse control stage exits, a slow retreating stage is introduced, and in the slow retreating stage, a descent coefficient is generated according to real-time driving state information; generating a final output control quantity according to the descent coefficient; performing transverse control on the vehicle according to the final output control quantity; and according to the final output control quantity and the slow retreat time, controlling the exit of the slow retreat stage. The slow retreating stage is introduced, various working conditions during retreating can be considered, corresponding parameters are adjusted according to driving state information and driver control information during retreating, normal retreating of the system can be guaranteed, various working conditions during retreating can be considered, and system safety is effectively improved.
本申请公开了一种车辆横向控制退出算法策略,涉及智能驾驶技术领域,解决了现有车辆的辅助驾驶系统中的横向控制系统难以根据实时的行驶情况判断是否能够直接退出;当中横向控制在退出时,安全性较低的技术问题;包括:在横向控制阶段退出时,引入缓退阶段,在缓退阶段内,根据实时的行驶状态信息生成下降系数;根据下降系数生成最终输出控制量;根据最终输出控制量对车辆进行横向控制;并且根据最终输出控制量以及缓退时间,控制缓退阶段的退出;引入缓退阶段,可以兼顾退出时的各种工况,根据退出时的行驶状态信息和驾驶员操控信息对相应的参数进行调整,既能保证系统正常退出,又能考虑在退出阶段的各种工况,有效提升了系统安全性。
