Abstract

The invention provides a traffic jam auxiliary system and belongs to the field of automobile safe driving. The traffic jam auxiliary system comprises a front camera detecting information of surrounding environment of an automobile in front, and transmitting the environment information to a radar probe in front via a CAN bus, the front radar probe detecting front environment information and automobile information and receiving pedestrian information sent by the front camera and re-determining the automobile information, receiving self-automobile state information, conducting fuse processing to determine a distance between two automobiles and sending out an instruction to a related vehicle-mounted ECU executing unit, and a vehicle-mounted ECU executing unit receiving an instruction of a processing unit and executing the instruction. The front camera, the front radar probe and the vehicle-mounted ECU executing unit are connected via a vehicle-mounted CAN network; and the traffic jam auxiliary system aims to achieve seamless connection between low-speed traffic jam assistance and high-speed high-way road assistance.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a traffic congestion assisting system. Background technique [0002] When the road is congested, the driving speed of the vehicle is low (vehicle speed <60km / h) and the driving condition is single. Generally, it creeps forward following the vehicle in front. At this time, the driver is prone to carelessness, impatience, fatigue and accidents due to monotonous driving, so it is urgently needed A function capable of driving instead of a human in such conditions. [0003] The traffic jam assistance function belongs to partial automatic driving, which is suitable for assisting driving in monotonous driving conditions, and can ensure the driver's safe and easy driving in traffic jams. The driver needs to keep monitoring the vehicle and the surrounding environment at all times; the system can simultaneously control the vehicle's lateral and longitudinal directions. The system integrat...
