Abstract

The invention provides a motorcade autonomous car following system, a portable device and a method; the system comprises the following parts: a GPS module in a data acquisition unit is used for gathering vehicle positioning information, and an inertial navigation module in the data acquisition unit is used for gathering vehicle acceleration information and angular velocity information; a fusion positioning module in a data processing unit is used for fusing the GPS information and inertial navigation information in real time, thus obtaining a self-vehicle absolute pose; a car following controlcalculation module is used for planning an absolute route according to the self-vehicle absolute pose information, front vehicle absolute pose information and a head vehicle history route, updating an absolute route table, and calculating to obtain a vehicle target velocity and direction turning angle for vehicle control. The system and method can realize combined positioning via the GPS module and the INS module, are high in positioning precision, high in data refreshing frequency, and cannot be affected by illumination and weather environment factors, thus effectively improving the autonomous car following system precision and reliability. The device is portable and easy to construct, and low in cost.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to the technical field of autonomous car following, and in particular, to an autonomous car following system for a team, a portable device and a method. Background technique [0002] With the emergence of diversified transportation needs, autonomous driving technology has gradually been more widely used. Autonomous vehicle-following technology, that is, a leading vehicle in the vehicle queue is driven by an operator, and other vehicles follow the path of the leading vehicle to drive automatically, which can effectively solve problems in various scenarios. For example, the short-distance movement of a large number of cars, the use of autonomous car-following technology can reduce the number of drivers; another example is short-distance multi-person connection, the use of autonomous car-following technology can increase the number of people carried under a limited number of ve...
