Distributed electric vehicle congestion following control system and method

Abstract

The invention discloses a distributed electric vehicle congestion following control system and method. A data collection system collects vehicle status information and environmental information duringnormal driving of a vehicle; a vehicle following intention of a driver is collected through a human-vehicle interaction system; an overall vehicle control system judges whether or not the vehicle isin a safe state and whether or not the driver has the vehicle following intention according to vehicle status information and environmental information, if it is judged that the vehicle is in a unsafestate, the whole vehicle control system controls a safety early warning system to give an alarm; when the driver has the vehicle following intention, the overall vehicle control system sends a control instruction to an actuator system, the vehicle running speed, direction and driving modes are adjusted, vehicle following running is conducted on the condition that the vehicle distance is kept unchanged. Accordingly, vehicle following running in traffic jam road sections is achieved, all or part of operation of the driver is liberated, and the fatigue of the driver is relieved.

Description

technical field [0001] The invention belongs to the technology of distributed electric drive vehicles, and relates to a control system and method of distributed electric drive vehicles. Background technique [0002] With the increase in the number of cars in my country, traffic jams on highways occur frequently, and traffic lights in dense roads in cities delay traffic flow; drivers need to operate frequently to control the car, so as to follow the car in front. This frequent switching makes the vehicle's Both energy consumption and driver's energy consumption are on the high side. At present, most of the follow-up systems for urban congestion conditions are only for fuel vehicles and ordinary electric vehicles. Due to their own limitations, although fuel vehicles have automatic start-stop technology that can properly reduce energy consumption, the effect is not obvious; Electric vehicles are relatively complex in terms of control technology, which affects driving comfort an...

[0002] With the increase in the number of cars in my country, traffic jams on highways occur frequently, and traffic lights in dense roads in cities delay traffic flow; drivers need to operate frequently to control the car, so as to follow the car in front. This frequent switching makes the vehicle's Both energy consumption and driver energy consumption are high

At present, most of the follow-up systems for urban congestion conditions are only for fuel vehicles and ordinary electric vehicles. Due to their own limitations, although fuel vehicles have automatic start-stop technology that can properly reduce energy consumption, the effect is not obvious; Electric vehicles are relatively complex in terms of control technology, which affects driving comfort and economy
