Internal-combustion engine controlling method for motor vehicle, involves executing resonance detection with actual value and applying corrective measures or containment actions to internal-combustion engine based on actual value

摘要

The method involves forming an actual value by processing signals of a sensor device. The actual value is compared with a given threshold value. Moment interference is resulted in an internal-combustion engine when the actual value exceeds the threshold value. Resonance detection is made with the actual value in a flow control after checking input conditions that fall below a number of revolutions of the internal-combustion engine. Corrective measures or containment actions are applied to the internal-combustion engine based on the actual value. The moment interference in the engine is caused by a change of an opening angle of a throttle valve, a change of the injection amount, a change of the injecting angle, a change of the dwell angle of a control valve and/or a change of the ignition of the internal-combustion engine.
