A transporter trailer system

Abstract

The invention discloses a trailer system for a transport vehicle, which includes a range extender controller, a motor controller and a high-voltage distribution box. The range extender controller is connected to an engine controller through a relay controller, and the engine controller is connected through The APU bus is connected with an instrument system, the engine controller is connected to the motor controller through the CAN bus, the motor controller is connected to the high-voltage distribution box through a coaxial parallel control system, and the high-voltage distribution box is internally provided with A voltage conversion circuit, the control end of the voltage conversion circuit is connected to the motor controller through a signal acquisition circuit, the system starts from the combination of global optimization and real-time optimization, and formulates a range extender control strategy. In the system structure, the controller and the actuator One-to-one correspondence, clear levels, clear functions, high control efficiency, and strong anti-interference.

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
