Abstract

The invention provides an assisted driving system for actively dodging large vehicles in a lane, including a perception module, a decision-making module, a planning module, a tracking module and a controller, the perception module includes an environment perception sensor, and the environment perception sensor signal is connected to the decision-making module The input terminal of the decision-making module determines the four states of the assisted driving system through the signal of the environment perception sensor, and the output signal of the decision-making module is connected to the input terminal of the planning module. The module output signal is connected to the input of the tracking module. The assisted driving system for actively dodging large vehicles in a lane according to the present invention can realize automatic target recognition, decision-making, active dodging trajectory planning and dodging action execution functions in the scene of overtaking large vehicles, and can improve the performance of the vehicle in this scene. Side collision safety, as well as the peace of mind of drivers and passengers.

Description

technical field [0001] The invention belongs to the technical field of active safety technology, advanced driving assistance system, automatic driving perception, decision-making, planning and tracking, and in particular relates to an auxiliary driving system for actively dodging large vehicles in a lane. Background technique [0002] ADAS (Advanced Driver Assistant System) is an advanced driver assistance system that collects road and environmental vehicle parameters in the vehicle driving environment through on-board sensors, and performs target identification, detection and tracking, so that it can predict the risks that the vehicle may encounter and actively change the vehicle. The state of motion of the vehicle or actively remind the driver to improve safety. Commonly used sensors in ADAS systems include: millimeter wave radar, laser radar, ultrasonic radar, camera, etc. According to the actuators controlled by its assisted driving system, ADAS systems can be divided i...
