Problems solved by technology

[0004] However, truck cranes have the characteristics of long fixed-point working hours and low transition frequency. The hoisting conditions do not meet the driving regeneration conditions, and the carbon load of the DPF continues to increase. If the user cannot perform parking regeneration in time during use, the carbon load of the DPF will Continued increase will cause DPF blockage and damage, causing safety accidents

Abstract

The embodiment of the present invention discloses a power system control device and a control method thereof. The control device includes: a main control module and a particle catcher; the particle catcher is used to catch carbon particles during operation; the main control module is used to obtain particle The carbon load of the trap determines the target carbon load range to which the carbon load belongs, and controls switching to the target working condition corresponding to the target carbon load range in the next driving cycle. In the embodiment of the present invention, the working condition corresponding to the carbon load range is the working condition to ensure driving safety when the carbon load of the DPF is in the carbon load range. Under certain circumstances, the main control module controls the power system to switch to the target working condition corresponding to the target carbon load range in the next driving cycle, which can adjust the power performance of the power system in time to ensure driving safety, and can also remind the user to clear the DPF in time accumulated carbon particles.

Description

technical field [0001] Embodiments of the present invention relate to automatic control technology, and in particular to a control device and a control method for a power system. Background technique [0002] At present, the aftertreatment of truck cranes that meet the requirements of the National VI emission regulations are equipped with particle traps DPF. DPF is a particulate filter, so as the use time increases, there will inevitably be particle clogging. It is necessary to remove the carbon particles accumulated in the DPF. This removal operation is called DPF regeneration. DPF regeneration includes passive regeneration and active regeneration. . [0003] The truck crane is mainly used for hoisting operations. During the hoisting operation, the engine runs at low speed and low load, and the accumulation rate of carbon particles in the DPF is high. In addition, the exhaust temperature of the engine is low when the engine is running at low load, and the passive regenerat...
