Air inlet throttle valve control method and device and electronic equipment

The invention discloses an air inlet throttle valve control method and device and electronic equipment, and is applied to the technical field of engines. The method comprises the steps that a target braking grade is determined based on braking parameters of a vehicle, and the total braking power corresponding to the target braking grade is determined; obtaining a target predicted temperature of a current post-processing system of the engine; carrying out braking power distribution on the total braking power based on the target predicted temperature to obtain braking power in an engine cylinder; and according to the braking power in the engine cylinder and the target braking grade, the target opening degree parameter of the air inlet throttling valve is determined, so that the opening degree of the air inlet throttling valve is controlled based on the target opening degree parameter. On the basis of braking staged treatment, more suitable braking power is distributed in the engine cylinder so as to guarantee t
