System and method for adjusting an engine speed and / or an engine load in order to improve the force of material economy without excitation of by means of a fahzeuginsassen perceptible vehicle vibrations

摘要

A system according to the principles of the present disclosure includes a vibration level module and a motor operation control module. The vibration level module estimates a first level of oscillation in a vehicle which, due to the contact between the tire of the vehicle and a road surface, when the vehicle travels over the surface of the road. The vibration level module estimates a second level of oscillation in the vehicle, the by a motor is caused in the vehicle. The motor operation control module represents a rotational speed of the engine and / or a load on the motor selectively when the second level of oscillation is lower than the first level of oscillation.
