Abstract:
The driving force controller for an electric vehicle that controls driving force of a motor in the drive system of an electric vehicle includes: a target driving force setting unit for setting the target driving force based on a request from a driver; a dividing unit for computing a first motor torque command value by dividing the target driving force by a reduction ratio; a target acceleration computing unit for computing target acceleration by dividing the target driving force by inertia of the drive system; an actual acceleration computing unit for computing actual acceleration by differentiating actual rotational speed of the motor; a correction amount computing unit for computing a correction amount for reducing deviation between the target acceleration and the actual acceleration; and a command value computing unit for computing a second motor torque command value by adding the correction amount to the first motor torque command value.
