Transport vehicle towing system

Abstract

The invention discloses a transport vehicletowing system. The systemcomprises a range extending controller, a motor controller and a high-voltage distribution box, wherein the range extending controller is connected with an engine controller through a relay controller; the engine controller is connected with an instrument system through an APU bus; the engine controller is connected with the motorcontroller through a CAN bus; the motor controller is connected with the high-voltage distribution box through a coaxial parallel control system; a voltage conversion circuit is arranged in the high-voltage distribution box; and the control end of the voltage conversion circuit is connected with the motor controller through the signal acquisition circuit. The system starts from the combination ofglobal optimization and real-time optimization, a range extender control strategy is formulated, the controllers and the actuators in the system structure are in one-to-one correspondence, the hierarchy is clear, the functions are clear, the control efficiency is high, and the anti-interference performance is high.

Description

technical field [0001] The embodiment of the present invention relates to the field of transport vehicle technology, and in particular to a transport vehicle trailer system. Background technique [0002] At present, in order to solve the problem of power outage maintenance or emergency repair, Dongguan Power Grid needs to purchase a set of 110kV mobile substation as a new substation to solve the urgent need for electricity for new loads but the new substation fails to be put into operation as scheduled, and users need to temporarily use substations and existing substations Due to the problem of urgent restoration of power supply after the equipment of the whole station is damaged by natural disasters, higher requirements are put forward for the towing device of the transport vehicle. The current transport vehicle towing system still has the following problems: [0003] (1) Although the current control strategy in the trailer system reduces the number of charge and discharge ...

Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a trailer system for a transport vehicle, which uses the SOC follow-up control algorithm to obtain the state of charge threshold of the power battery, formulates the control strategy for the start and stop time of the range extender, the power output strategy, and the start process control strategy. In the system structure, the controller and the actuator correspond one-to-one, with clear layers, clear functions, high control efficiency, and strong anti-interference to solve the problem of the narrow working area and high cost of the generator in the trailer system of the transport vehicle in the prior art. High, high interference, and short battery life issues
