The inhibition device includes a micro-controller configured with a triggering condition including a number of intervals and, for each interval, a corresponding duration and a corresponding threshold. Each interval is a range specifying how much the vehicle's acceleration pedal has changed its position in terms of percentages of a pedal stroke. Each duration specifies the fastest time duration allowable for the acceleration pedal to attain a corresponding interval of pedal position change. The micro-controller converts progress signals of the acceleration pedal to corresponding percentages, obtains a difference DEF between the successive percentages, records a time duration RES between successive progress signals, and calculates DEF/RES=X. When X is greater than or equal to a threshold of a corresponding interval, the micro-controller sends an idle signal to the vehicle's engine control unit or intercepts the progress signals to prevent them from reaching the engine control unit.

An embodiment control device for discharging condensed water includes a signal receiver configured to receive a power-starting off signal, a temperature receiver configured to receive outdoor air temperature information, and a controller configured to perform a condensed water discharge mode maintaining an engine under an idling condition during a preset power-starting maintenance period in response to the power-starting off signal being received by the signal receiver and the outdoor air temperature information received from the temperature receiver being equal to or lower than a set temperature value.

Systems and methods for removing accumulated soot in an aftertreatment system are disclosed herein. A method includes: determining, by a controller, an adsorption amount of soot in an exhaust aftertreatment system; comparing, by the controller, the adsorption amount of soot to a predefined adsorption amount limit; in response to the adsorption amount exceeding the predefined adsorption amount limit, initiating, by the controller, an exhaust cleaning event to remove at least some accumulated soot in the exhaust aftertreatment system; receiving, by the controller, exhaust gas data during the exhaust cleaning event; determining, by the controller, a desorption amount of soot based on the exhaust gas data; comparing, by the controller, the desorption amount of soot to a predefined desorption limit; and ceasing, by the controller, the exhaust cleaning event based on the comparison.

Systems and methods for removing accumulated soot in an aftertreatment system for an engine are disclosed herein. A method includes receiving an indication that an engine of a vehicle has been operating in a low load condition for more than a predefined amount of time; in response, determining an adsorption rate of soot in an exhaust aftertreatment system of the vehicle; determining an adsorption amount of soot based on the adsorption rate for a predefined amount of time; comparing the adsorption amount to a predefine adsorption amount limit; and in response to the adsorption amount exceeding the predefined adsorption amount limit, initiating an exhaust cleaning event to remove at least some of the accumulated soot in the exhaust aftertreatment system.
