Abstract

The invention provides a carbon canister load control method and device and a computer readable storage medium. The carbon canister load control method comprises the steps that a current actual oil vapor adsorption load of a carbon canister is obtained at any moment; whether the adsorbability of the carbon canister is insufficient or not is judged according to the current actual oil vapor adsorption load of the carbon canister; and if the adsorbability of the carbon canister is insufficient, an engine is controlled to start, a carbon canister control valve is opened, and the carbon canister is subjected to washing desorption treatment so as to reduce the oil vapor adsorption load of the carbon canister. According to the carbon canister load control method, the risk that in the prior art, oil vapor overflows due to the fact that too much oil vapor enters the carbon canister and exceeds the adsorption capacity of the carbon canister can be solved.

Description

technical field [0001] The invention relates to the technical field of automotive electronic control, in particular to a method and device for controlling a canister load and a computer-readable storage medium. Background technique [0002] For hybrid vehicles that can run purely on electric power for a long time, due to the shorter engine running time, the chance of flushing the canister is reduced, which may reduce the adsorption capacity of the canister and increase the risk of oil vapor overflowing the atmosphere from the atmospheric port of the canister, resulting in evaporative emissions. deterioration. With the newly added evaporative system leakage diagnosis requirements in China VI, the fuel tank of strong hybrid or plug-in hybrid vehicles is generally designed as a non-integral carbon tank system that only controls refueling and emission, such as figure 1 As shown, the main components involved in the system are: pressure fuel tank 1, fuel tank pressure sensor 2, f...
