Embodiment Construction

[0028] Embodiments of the system and method for real-time analysis of traffic reference data of the present invention will be described in detail below.

[0029] When the vertical and horizontal automatic control is realized, the vehicle can be automatically controlled to run according to the given target and constraints. Therefore, from the perspective of the car itself, autonomous driving is comprehensive longitudinal and lateral control. But to truly achieve point-to-point autonomous driving, vehicle control systems must acquire detailed dynamic information on road and surrounding traffic conditions and have highly intelligent control performance. A complete traffic information system, high-performance, high-reliability on-board sensors and intelligent control systems are important prerequisites for autonomous driving. Due to the difficulty of point-to-point automatic driving, people put forward the concept of first realizing the automatic driving section, that is, to open...

Abstract

The invention relates to a passage reference data real-time analysis system, which comprises an ultrasonic ranging mechanism arranged at the front end of a vehicle and used for measuring the distancefrom a front target to the front end of the vehicle; the signal conversion equipment is used for sending a frame body extending signal when the distance from the front target to the front end of the vehicle is smaller than a preset distance threshold value, otherwise, sending a frame body contracting signal; and the frame body driving motor is connected with the signal conversion equipment and thesafety protection frame, and is used for enabling the safety protection frame to extend out of a vehicle body at the front end of the vehicle and to be fixed at the front end of the vehicle when receiving the frame body extending signal. The invention further relates to a traffic reference data real-time analysis method. The passage reference data real-time analysis system and the passage reference data real-time analysis method are wide in application and have a certain automation level. Due to the fact that the feasibility that the vehicle keeps the current speed to bypass the front crack is judged under the condition that the multiple relevant parameters are obtained, important driving auxiliary data are provided for a vehicle driver.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a system and method for real-time analysis of traffic reference data. Background technique [0002] Automatic vehicle control, in fact, is to apply some automatic control technologies to the traffic system, from improving mechanical performance in the past to assist or partially replace or completely replace human manipulation, so as to reduce accidents caused by human limitations and reduce driving. Intensity aims to improve traffic efficiency and reduce pollution. [0003] The vehicle speed control is the control in the direction of the driving speed, that is, the automatic control of the vehicle speed and the distance between the vehicle and the front and rear vehicles or obstacles is a kind of longitudinal control. This type of control problem boils down to the control of engine output and braking. Various engine models, vehicle operation models and braking process models are...
