Abstract

The invention provides a method for controlling an air inlet throttle valve, a control device, an electronic control unit and a vehicle. The method comprises the steps that the electronic control unit sends an operation mode of an engine to an automatic gearbox control unit, when the automatic gearbox control unit recognizes that the operation mode comprises a heat management mode or a diesel particulate filter driving regeneration mode, gear shifting control and rotating speed correction control are conducted on an automatic gearbox, so that the engine operates in a large-load area, the exhaust temperature of the engine is increased, and ending of the heat management mode or the diesel particulate filter driving regeneration mode is accelerated. Then, when the electronic control unit obtains that the automatic gearbox control unit is in the gear shifting control mode, the opening size of the air inlet throttle valve of the engine is corrected according to the obtained accelerator pedal opening degree or the accelerator pedal opening degree change rate, an opening of the air inlet throttle valve is temporarily increased, and the dynamic property of the engine is improved.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a method, device, electronic control unit and vehicle for controlling an air intake throttle valve. Background technique [0002] In order to meet the emission requirements, the National VI engine is installed with a diesel particulate filter (Diesel Particulate Filter, DPF) to capture the soot particles in the exhaust. When the carbon load of the diesel particulate filter reaches a certain value, it will be regenerated Oxidizes soot particles in the diesel particulate filter. [0003] When the regeneration mode of the diesel particulate filter is in progress, the electronic control unit (Electronic Control Unit, ECU) needs to reduce the opening of the intake throttle valve to increase the exhaust temperature. In addition, when the exhaust temperature is low, the engine enters the thermal management mode, and the purpose of thermal management is achieved by reducin...
