Ash removal control device and method for vehicle

Abstract

The invention discloses an ash removal control device and method for a vehicle. The ash removal control device comprises an engine oil quality sensor and a main control module, wherein the engine oilquality sensor is used for detecting the content of each element in engine oil; and the main control module is electrically connected with the engine oil quality sensor and used for determining inorganic substance integral information according to the content of each element in the engine oil, and issuing an ash removal instruction when detecting that the inorganic substance integral information reaches a set integral threshold value. According to the ash removal control device and method for the vehicle, the engine oil quality sensor is used for detecting the content of each element in the engine oil; the main control module is used for determining the inorganic substance integral information according to the content of each element in the engine oil, and issuing the ash removal instruction when detecting that the inorganic substance integral information reaches the set integral threshold value; and the ash accumulation condition of a DPF is determined by analyzing the inorganic substance content in the engine oil, and when the ash removal content, namely the set integral threshold value is reached, the ash removal instruction is generated to remind a driver to remove ash, so thatthe driving hidden danger caused by the blockage of the DPF is avoided, and the driving safety is improved.

Description

technical field [0001] The embodiment of the present invention relates to DPF dust removal technology, and in particular to a vehicle dust removal control device and method. Background technique [0002] As we all know, the diesel engine will have a certain amount of oil consumption during the working process, that is, the oil will be left on the inner wall of the piston and discharged out of the engine after burning the diesel. Due to various additives and other reasons, the content of inorganic substances in engine oil is much higher than that of diesel oil. These inorganic substances will form ash after entering the post-treatment DPF with the exhaust gas. These ash cannot be regenerated by high temperature. Therefore, when the ash content of the DPF accumulates to a certain extent, it needs to be removed for cleaning or purging. [0003] However, it is difficult to judge the ash accumulation degree of DPF in the prior art, which brings uncertainty to the DPF ash cleanin...
