Abstract

The invention provides a super highway auxiliary system, and belongs to the field of safe driving of automobiles. The super highway auxiliary system comprises a radar sensor, a camera sensor, a central controller and a vehicle-mounted ECU execution unit, wherein the radar sensor is used for detecting environmental information and vehicle information around a current vehicle; the camera sensor is used for collecting the environmental information around the current vehicle; the central controller is used for receiving the information transmitted from the radar sensor and the camera sensor, collecting the vehicle information of the current vehicle transmitted by an ECU, integrating the information for processing and judgment, and issuing an instruction to the relevant vehicle-mounted ECU execution unit; and the vehicle-mounted ECU execution unit is used for receiving the instruction and controlling the current vehicle to execute the instruction. Through the adoption of the super highway auxiliary system provided by the invention, the hands and feet of a driver are liberated to the greatest extent, so that driver fatigue due to a monotonous driving mode is avoided; the seamless connection between super highway assist and traffic jam assist is realized; and two cases that changing lanes is dangerous and changing lanes is safe are distinguished by the system, and different assists are provided for the driver, so that not only is the lane change security guaranteed, but also the convenience of lane change is provided, and the driving pleasure is improved.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a highway auxiliary system. Background technique [0002] The working conditions of highways are relatively simple compared with urban roads, and most of the vehicles on highways travel long distances. If the driver drives for a long time, it will undoubtedly cause fatigue. HWA (Highway Assist System) was developed for such working conditions. The Highway Assist system is a part of autonomous driving, which requires the driver to keep monitoring the vehicle and the surrounding environment at all times. The highway assist system can control the lateral and longitudinal directions of the vehicle at the same time; the longitudinal control can realize the speed range of (0-130) km / h; the lateral control can realize the speed range of (0-180) km / h, which can support high speed Highway and better urban road conditions (simple road conditions without intersections, pedestrians, battery ca...
