BRT bus longitudinal automatic driving control method and control system

Abstract

The invention discloses a BRT bus longitudinal automatic driving control method and control system, and the method comprises the steps: obtaining the speed information and positioning signals of a bus, and judging the current position of the bus and the course angle of the bus; determining a preset area code corresponding to the position of the bus lane according to the positioning signal; according to the vehicle course angle and a preset lane course angle, the driving direction of the bus and a preset lane code are judged; according to the current lane code and the corresponding road information, speed limit information and station information, a target vehicle speed is obtained through calculation according to an automatic driving algorithm, a motor control signal is obtained through comprehensive calculation, and a motor is controlled to operate. Through the technical scheme of the invention, automatic following driving is realized, the bus spacing can be dynamically adjusted, overall planning is realized, the control behaviors of a driver can be greatly reduced, the driving fatigue degree of the driver is relieved, and the riding experience of passengers is improved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a BRT bus longitudinal automatic driving control method and a BRT bus longitudinal automatic driving control system. Background technique [0002] BRT urban buses operate on closed or semi-closed special roads, with fixed routes and large distance between stations. Manual driving is mainly divided into horizontal control, namely the steering wheel, and longitudinal speed control, namely accelerator and brake. [0003] In this driving scenario, the driver needs to pay attention to whether the speed of the vehicle is overspeed, and has to keep stepping on the accelerator and brake to control the speed of the vehicle, which is prone to fatigue driving. Moreover, different drivers have different driving habits, which are prone to rapid acceleration and rapid deceleration, which will bring bad feelings to passengers. Different driving styles also lead to uneven int...

[0003] In this driving scenario, the driver needs to pay attention to whether the speed of the vehicle is overspeed, and has to step on the accelerator and brake to control the speed of the vehicle, which is prone to fatigue driving

Moreover, different drivers have different driving habits, which are prone to rapid acceleration and rapid deceleration, which will bring bad feelings to passengers

Different driving styles also lead to uneven inter-vehicle spacing on the line, which is too far from the regulation of one shift at a fixed time, and the passenger experience of waiting for the bus is not good.
