Embodiment Construction

[0061] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0062] This embodiment is based on Tesla model 3 as an example to illustrate the control process method of the vehicle adaptive cruise system based on information sharing:

[0063] Use the millimeter wave and camera installed in this model as components, process the information obtained by these components with its built-in intelligent driving program, and transmit the obtained information to the on-board CPU described in this solution. An adaptive cruise system (vehicle H) based on information sharing, its components are as follows:

[0064] 1) Environmental perception module: including millimeter-wave radar and camera, used to obtain the position and motion state data of objects around the...

Abstract

The invention discloses a self-adaptive cruise control method and system based on information sharing. The control method comprises the steps that the current driving state of a vehicle and positionsand motion states of objects around the vehicle are obtained; the state information is interacted with surrounding vehicles, then importance screening is conducted on the state information and the environment information of the surrounding vehicles; and information possibly generating interference on the vehicles is obtained and input into a vehicle-mounted CPU for decision making and then a control execution module performs braking. Therefore, self-adaptive vehicle speed control over the vehicle is achieved.

Description

technical field [0001] The invention relates to an adaptive cruise control method and system based on information sharing, and belongs to the fields of advanced vehicle auxiliary driving control and vehicle active safety. Background technique [0002] With the increasing maturity of vehicle electronic control technology, the intelligence level of vehicles is also constantly improving. Different from the completely unmanned driving system, the application of advanced assisted driving functions in vehicles is becoming more and more extensive. At present, passenger cars with L2 level assisted driving systems have begun to appear on the market. The advanced assisted driving function collects and comprehensively analyzes the information of the environment and the vehicle through various sensors on the vehicle, and provides auxiliary control for the vehicle in certain scenarios, which can reduce driver fatigue to a certain extent and increase the safety of the vehicle during drivi...
