Abstract

The invention discloses a method, device and system for fault solution of an electronic throttle valve, and a storage medium. The method comprises the steps that an initial deviation distance betweena current position of the electronic throttle valve and a preset standard position is acquired; whether the initial deviation distance exceeds a preset deviation threshold is judged, wherein if the preset deviation threshold is exceeded, valve scouring is conducted on the electronic throttle valve, and an actual deviation distance between the electronic throttle valve and the preset standard position is acquired when the valve scouring is completed; and if the actual deviation distance does not exceed the preset deviation threshold, the electronic throttle valve can be deemed to be free of faults. The valve scouring is conducted on the electronic throttle valve when the deviation distance between the current position of the electronic throttle valve and the standard position exceeds the deviation threshold; then, whether the actual deviation distance from the standard position after the valve scouring exceeds the preset deviation threshold is detected; and if the preset deviation threshold is not exceeded, success of the valve scouring can be judged, and the electronic throttle valve is deemed to have no blocking faults, so the problem of blocking of the electronic throttle valve can be detected and solved effectively in time, and driving and riding experience can be improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method, device, system and storage medium for troubleshooting an electronic throttle valve. Background technique [0002] Environmental protection is one of the important issues facing human beings in modern life. With the rapid development of the economy, automobiles have entered thousands of households and become the current mainstream way of travel. At the same time, the issue of automobile exhaust emissions has attracted more and more attention from the public. [0003] With the upgrading of emission requirements, electronic throttle valves have been widely used in internal combustion engines such as diesel engines and gasoline engines. Diesel engine throttle valves are generally arranged in front of the exhaust gas recirculation (Exhaust Gas Recirculation, EGR) outlet, so that the exhaust gas from EGR will condense into liquid droplets and flow back to the position of...
