Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2022149614
Kind Code:
A
Abstract:
To provide a vehicle control device that can suppress occurrence of noise due to electrical resonance when driving an electric motor.SOLUTION: An vehicle control device mounted on a vehicle configured such that a first drive source being an electric motor outputs torque to a first wheel, comprises: a storage part storing a first resonance map; and a control unit that calculates a first torque command value showing a value of torque which the first drive source is made to output and can switch the control method of the first drive source. In the first resonance map, one or a plurality of operation points in which resonance occurs in an operation region of the first drive source to which rectangular wave control is performed, are shown as first resonance points (X1). When a predicted movement destination (k3) of an operation point (A) of the first drive source overlaps with the first resonance point, the control unit switches the control method of the first drive source from rectangular wave control to sinusoidal wave control.SELECTED DRAWING: Figure 6
