A 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. The method includes: acquiring the speed information and positioning signal of the bus, and judging the current position of the bus and the heading angle of the vehicle; determining the location of the bus according to the positioning signal The preset area code corresponding to the location of the bus lane; according to the vehicle heading angle and the preset lane heading angle, judge the driving direction of the bus and the preset lane code; according to the current lane code and the corresponding road information, speed limit information and station Information, according to the automatic driving algorithm, calculate the target vehicle speed, comprehensively calculate the motor control signal and control the operation of the motor. Through the technical solution of the present invention, it is possible to automatically follow the bus, dynamically adjust the distance between buses, realize the overall planning, and greatly reduce the driver's manipulation behavior, relieve the driver's driving fatigue, and improve the passenger's riding experience.

Description

technical field [0001] The 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 city buses run on closed or semi-closed dedicated roads, with fixed routes and large distance between stops. Manual driving is mainly divided into lateral control, namely 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 or not, and has to constantly step on the accelerator and brake to control the vehicle speed, which is prone to fatigue driving. Moreover, different drivers have different driving habits, and are prone to sudden acceleration and sudden deceleration, which will bring bad feelings to passengers. Different driving styles also lead to uneven spacing between cars o...

Problems solved by technology

[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.
