The invention discloses a heat dissipation control method and device for a hybrid electric vehicle and a storage medium, and belongs to the technical field of vehicle engineering. The heat dissipationcontrol method comprises the steps that in the process that the hybrid electric vehicle is in a starting state, a current running mode of the hybrid electric vehicle is determined; a corresponding running state of a vehicle-mounted air conditioner of the hybrid electric vehicle in the current running mode of the hybrid electric vehicle is obtained; fan control parameters of the hybrid electric vehicle are determined according to the current running mode of the hybrid electric vehicle and the running state of the vehicle-mounted air conditioner; and according to the fan control parameters, a fan of the hybrid electric vehicle is controlled, so that heat dissipation control over the hybrid electric vehicle is achieved. According to the heat dissipation control method, the fan control parameters are determined according to the running mode of the hybrid electric vehicle and the running state of the fan, so that the hybrid electric vehicle can be cooled accurately according to the fan control parameters, the situation that the heat dissipation effect of the hybrid electric vehicle is poor or excessive is improved, and the heat dissipation efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of vehicle engineering, in particular to a heat dissipation control method, device and storage medium of a hybrid electric vehicle. Background technique [0002] With the development and rise of the new energy market, plug-in hybrid vehicles have attracted more and more attention because of their advantages such as low fuel consumption and no mileage anxiety. Among them, plug-in hybrid vehicles can be driven by batteries, motors, engines, etc. Therefore, the performance of batteries, motors, and engines will affect the power, economy and environmental protection of hybrid vehicles. The temperature of the battery, motor, and engine is one of the factors that affect the performance of the battery, motor, and engine. Therefore, in order to avoid affecting the performance of the battery, motor, or engine due to excessive temperature of the battery, motor, or engine, it is usually necessary to control t...
