Control method for providing stable kickdwon signal for gearbox

The invention relates to the technical field of gearbox gear shifting control, in particular to a control method for providing a stable kickdwon signal for a gearbox. The opening degree of an accelerator is monitored in real time, and when the opening degree of the accelerator is larger than or equal to a first preset opening degree value, a kickdwon signal is triggered and set; the set kickdwon signal is sent to the gearbox, and the set kickdwon signal is sent to the gearbox; and after the kickdwon signal is set for a set time length, the kickdwon signal is automatically reset, and the reset kickdwon signal is sent to the gearbox. According to the method, the phenomenon that the AMT frequently shifts gears when a driver operates a large accelerator when the accelerator pedal used by a matched AMT vehicle does not have a mechanical kickdown function or has the mechanical kickdown function but the point is large in scatter difference or fails is improved in a targeted mode, and the method has important signifi
