Problems solved by technology

However, there are two problems in the current GPS method, one is the positioning accuracy problem, the general error is on the order of 10 meters, which is not enough for vehicle collision avoidance; the other is the integrity problem of information acquisition, for example, only the accuracy can be obtained through GPS The low speed of the vehicle not only has problems in accuracy, but also the information of other vehicles can only be obtained by estimation

Abstract

The invention provides an adaptive cruising system and a vehicular apparatus. The system comprises: a point cloud data collector for collecting a plurality of point clouds in a front road scene during driving of a motor vehicle; a multi-dimensional vehicle candidate area determining device for determining a ground plane in the front road scene based on the plurality of point clouds output by the point cloud data collector, wherein a plurality of multi-dimensional areas are generated on the ground plane according to preset vehicle dimensions and whether the multi-dimensional areas are multi-dimensional vehicle candidate areas or not is determined; a ranging device for detecting spacing between the motor vehicle and the multi-dimensional vehicle candidate areas according to the multi-dimensional vehicle candidate areas determined by the multi-dimensional vehicle candidate area determining device; and a controller for carrying out crushing control for the motor vehicle according to the spacing. The system and apparatus allow vehicles in the front road scene to be recognized and positioned quickly and accurately and allow for adaptive crushing control.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicle environment perception, in particular to an adaptive cruise system and vehicle-mounted equipment. Background technique [0002] Among the automobile safety problems, the automobile collision problem should be paid enough attention. The current automobile anti-collision technology focuses on the research on the collision prevention of rear-end collisions of straight-line vehicles, the core of which is the calculation of the safe distance between vehicles. [0003] In related technologies, GPS is mainly used for vehicle distance measurement, and GPS information is used to obtain information such as latitude and longitude, speed, and heading of the vehicle, so as to calculate the braking distance. However, there are two problems in the current GPS method, one is the positioning accuracy problem, the general error is on the order of 10 meters, which is not enough for vehicle collision avo...
