Abstract

The invention discloses an automatic vehicle-following device and a method and belongs to the technical field of a vehicle. The device comprises an acquiring device and a control module, wherein the acquiring device is used for acquiring driving states of surrounding vehicles and confirming operations executed by the surrounding vehicles according to the driving states; the surrounding vehicles are arranged as the vehicles in a preset scope surrounding a first vehicle; the running state of each vehicle comprises one or more of driving speed, gear, brake use condition, engine running condition, steering of a steering wheel, distance away from the first vehicle, and a driving track; the operations of each vehicle comprise one or more of shifting D-gear, shifting P-gear, braking, starting an engine and stopping the engine; the control module is used for controlling the first vehicle to execute a first operation after the automatic vehicle-following is started and the first operation is executed by the surrounding vehicles which are greater than or equal to the preset proportion in all the surrounding vehicles; the first operation is one of the operations. According to the invention, the vehicle-following reliability under a traffic jam condition is ensured and the driving fatigue is effectively relieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automatic vehicle following device and method. Background technique [0002] With the rapid growth of car ownership, road congestion has become a common phenomenon and is becoming more and more serious. What traffic jams bring to drivers is the distress of nervousness and frequent gear changes. [0003] The current automatic car-following device or system obtains the distance from the vehicle in front in real time through sensors and cameras in front of the vehicle, and keeps it within a set range through acceleration or braking actions to achieve car-following. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] The existing technology always follows a certain target in the front, which has great limitations. When the road condition is congested, there are many vehicles, ...
