Abstract

The invention relates to the technical field of vehicles, and particularly discloses an active heat management control method and device, a vehicle and a storage medium. The active heat management control method comprises the following steps: 1, determining the basic time and basic temperature of active heat management based on a low-temperature working condition proportion obtained in the vehicle testing process through testing the vehicle; 2, acquiring environmental parameters and correcting the basic time based on the environmental parameters to determine target time of active heat management; and 3, performing active heat management based on the target time and the basic temperature. The influence of environmental factors on main heat management is fully considered, the target time of active heat management is corrected through the environmental factors, the method can adapt to the environment where the vehicle is located, and the adaptability and the service life of a post-processing system are improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to an active thermal management control method, device, vehicle and storage medium. Background technique [0002] The diesel engine after-treatment system of the National VI emission standard includes DOC (diesel oxidation catalyst), DPF (diesel particulate filter), and SCR (selective catalytic reduction device). The weakening of passive regeneration in the environment leads to multiple challenges such as fast carbon deposition in the DPF and high risk of SCR crystallization when the exhaust temperature is low; these problems will lead to frequent failures of the after-treatment system, excessive emissions, shortened life, and affect vehicle operating efficiency. [0003] In this regard, in order to solve the above problems in the prior art, the actual temperature of the exhaust gas post-treatment device is usually detected and compared with the threshold temperature. When ...
