A control method for an automatic car-following system oriented to low-speed stop-and-go working conditions in urban environments

Abstract

The invention discloses an automated queue assistance system for a low-speed operating-and-stopping condition of an automobile in an urban environment and a control method thereof. A control system comprises a sensor, a controller and an actuator. The sensor comprises a millimeter-wave radar and an on-vehicle DSRC wireless communication receiving module. The actuator comprises the components of an engine power control unit, an ESC active brake unit, an electronic parking braking unit, an automatic transmission and an engine idle stop-start unit; wherein the engine power control unit, the ESC active brake unit, the electronic parking braking unit, the automatic transmission and the engine idle stop-start unit are based on on-vehice CAN bus communication. According to the control method, by means of automobile-automobile communication, automobile-road communication and collaborative control of the actuators, automatic automobile following is realized in a parking condition, a starting condition and a braking condition, thereby replacing throttle operation and braking operation of a driver. The automated queue assistance system has advantages of realizing automatic automobile following of a driver in the low-speed operating-and-stopping condition of the city, reducing driving fatigue, combining Internet-of-vehicles technology and collaborative control of a plurality of executing mechanisms, and effectively improving safety, fuel economy and sitting comfort in the automobile following process.

Description

technical field [0001] The invention relates to an automobile driver assistance system, in particular to a control method for an automatic follow-up system oriented to low-speed stop-and-go working conditions of automobiles in an urban environment based on vehicle-vehicle communication and vehicle-road communication. Background technique [0002] The vigorous development of the automobile industry has brought great convenience to people's lives, and has also caused a series of problems such as road congestion, traffic accidents, environmental pollution, energy shortages, etc. For this reason, it is necessary to coordinate the human-vehicle-road relationship in essence. relationship between. The Advanced Driver Assistance System (ADAS) is human-centered. By improving people's perception and decision-making ability of vehicles and roads, it can effectively reduce human-induced traffic accidents and improve driving comfort. Benefiting from information perception and vehicle co...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a low-speed stop-and-go operating system based on vehicle-to-vehicle communication and vehicle-to-road communication for the above-mentioned deficiencies in existing urban low-speed / stop-and-go working conditions. The control method of the automatic car-following system realizes multi-objective coordinated control and multi-actuator cooperative control. While effectively reducing the hidden danger of fatigue driving, it promotes the development of the assisted driving system in the direction of intelligence and practicality in an all-round way to meet driving safety. , riding comfort, fuel economy and other requirements
