Abstract:
A vibration suppression device of a vehicle includes a controller, a memory a vibration detector. The controller determines whether the vehicle is in a normal driving condition. The controller obtains data of a longitudinal vibration of the vehicle from the vibration detector. The controller determines whether a vibration level corresponding to a reference frequency band is greater than a vibration level threshold. The controller calculates a torque generated by each cylinder and a correction amount for the fuel injection amount for each cylinder so that a torque difference among the plurality of cylinders is reduced. The controller corrects the command fuel injection amount for each cylinder based on the calculated correction amount, controls each fuel injection device based on the corrected command fuel injection amount, and stores the calculated correction amount in the memory member.

Claim (Index 1):
A vibration suppression device of a vehicle, wherein the vehicle is equipped with an engine that includes a plurality of cylinders, each having a fuel injection device for fuel injection, comprising:\n a controller calculating a command fuel injection amount for each cylinder based on operating conditions of the engine and controlling each fuel injection device based on the calculated command fuel injection amount; a memory storing a correction amount for a fuel injection amount for each cylinder; and a vibration detector detecting a vibration of the vehicle, wherein the controller determines whether the vehicle is in a normal driving condition, the controller obtains data of a longitudinal vibration of the vehicle from the vibration detector if the controller determines that the vehicle is in a normal driving condition, the controller determines whether a vibration level corresponding to a reference frequency band is greater than a vibration level threshold with regard to the data of the longitudinal vibration of the vehicle, wherein the reference frequency band are set depending on a rotation speed of the engine, the controller calculates a torque generated by each cylinder and the correction amount for the fuel injection amount for each cylinder so that a torque difference among the plurality of cylinders is reduced if the vibration level corresponding to the reference frequency band is greater than the vibration level threshold, and the controller corrects the command fuel injection amount for each cylinder based on the calculated correction amount, controls each fuel injection device based on the corrected command fuel injection amount, and stores the calculated correction amount in the memory.
