Problems solved by technology

The inter-vehicle distance control of the vehicle formation is mainly the planning and control of the speed of the following vehicles. At present, the vehicle speed control of the vehicle formation control mainly considers the relative distance between vehicles. The speed of the vehicle is oscillating; in addition, the existing formation control methods rarely consider the brake pedal feedforward, which makes it difficult for the following vehicle to cope with the emergency braking scene of the leading vehicle

Abstract

The invention relates to a formation control method based on vehicle-to-vehicle communication. The method comprises the following steps that S1, information of adjacent leading vehicles is acquired through vehicle-to-vehicle communication equipment; s2, calculating the relative vehicle distance, the relative vehicle speed and the relative acceleration between the vehicle and the adjacent leading vehicle according to the position posture and state information of the vehicle; s3, the expected acceleration of the following vehicle is obtained according to brake pedal feedforward and error feedback, and limit value judgment is conducted on the expected acceleration; s4, the pedal opening degree is obtained through table look-up of the expected acceleration, and therefore the pedal opening degree of the vehicle is adjusted. Compared with the prior art, the method has the advantages of improving the safety of the formation vehicles in emergency and improving the running stability of the formation vehicles.

Description

technical field [0001] The invention relates to the field of intelligent vehicles, in particular to a formation control method based on vehicle-to-vehicle communication. Background technique [0002] In recent years, with the continuous increase of domestic car ownership, the traffic efficiency and safety of road traffic have received extensive attention. Appropriate vehicle spacing can not only improve road traffic efficiency and driving safety, but also reduce the wind resistance of high-speed driving to improve economic efficiency. In addition, the vehicle formation based on information interaction can learn the posture and information of adjacent formation vehicles, which can effectively improve vehicle driving. security. [0003] Vehicle formation means that the intelligent networked vehicle learns the pose, behavior, speed, acceleration and heading of the surrounding formation vehicles through vehicle-to-vehicle communication, comprehensively considers the information...
