Embodiment 1

[0028] Such as figure 1 As shown, an intelligent public transport safety driving behavior auxiliary supervision system consists of vehicle-mounted terminals, roadside terminals and ADAS cloud control center, and the surrounding peripheral systems include Beidou / GPS differential base stations and real-time signal lights. The vehicle-mounted terminal integrates and manages the DSRC perception communication unit, 360° panoramic video module, various sensors and high-precision positioning modules through the vehicle control host, accesses the vehicle CAN bus information and GPS / Beidou differential information, and provides the core vehicle active safety defense early warning Features. The roadside terminal integrates and manages the DSRC unit, the roadside video pedestrian and vehicle detection unit through the roadside control host, accesses information such as real-time signal light control, broadcasts the detected early warning information through the DRSC, and interacts with t...

Embodiment 2

[0035] A control method for an intelligent public transport safety driving behavior auxiliary supervision system, comprising:

[0036] S1. The vehicle-mounted terminal composes the active safety defense system of the vehicle through various sensors such as forward-facing ADAS cameras and vehicle-mounted radars. It senses roads, vehicles and pedestrians, and provides anti-collision warning information according to road conditions during driving.

[0037] S2. Vehicle-mounted terminals use GPS / Beidou base stations and high-precision maps deployed in the demonstration area, combined with precise positioning technologies such as GPS / Beidou differential and inertial navigation, to provide specific business location data information on sidewalks, traffic lights, bus stops, etc., for supply Autopilot system use.

[0038] S3. The vehicle-mounted terminal and the vehicle-mounted terminal form V2V perception and communication, and provide V2V-based collision warning information in all di...

Abstract

The invention discloses an intelligent bus safe driving behavior auxiliary supervision system and a control method. The system comprises a vehicle-mounted terminal, a roadside terminal and an ADAS cloud control center, a peripheral system comprises a Beidou / GPS differential base station and a real-time signal lamp, and a deep convolutional network and an SVM classifier are adopted to process driving behavior scale data. Parameter matching of a rear-end collision alarm / anti-collision algorithm is realized based on a driver abnormal behavior mode and experimental data statistics, vehicle CAN bus information and GPS / Beidou differential information are accessed to the vehicle-mounted terminal, a core vehicle active safety defense early warning function is provided, information such as real-time signal lamp control is accessed to the roadside terminal, and cooperative interaction with the vehicle-mounted terminal is realized; the Beidou / GPS differential base station is built in a demonstration area, accurate position information service is provided for the vehicle-mounted terminal in specific service position data information, the system can be used by an automatic driving system, user experience is good, the intelligent degree is high, input cost is low, data stability is good, and reliability is high.

Description

technical field [0001] The invention relates to an intelligent public transport safe driving behavior auxiliary supervision system and a control method, belonging to the technical field of intelligent public transport safe driving behavior. Background technique [0002] In recent years, advanced driver assistance systems have been widely used in some high-end vehicles, such as the "fatigue driving warning system" equipped by BYD, which uses the driver's facial features, eye features, head movement, etc. to infer the driver's fatigue status, And carry out alarm prompts and take corresponding measures; the "fatigue recognition system" equipped by Volkswagen records the driver's driving behavior for a long time, and judges the driver's fatigue level according to the change of his behavior; the "fatigue recognition system" equipped by Mercedes-Benz "Attention Assist System" uses 71 sensors on the car to detect longitudinal and lateral acceleration steering wheel and pedal sensor...
