A damping control device for a hybrid vehicle is provided that make it possible to suppress behavior that differs from a request of a driver. The damping control device includes a controller that calculates an amount of change in a target driving torque, and calculates an amount of change in a target motor torque. The damping control device also includes a damping rate variation unit that sets the damping of a feed forward control unit to a first damping rate when the target driving torque change amount and the target motor torque change amount both are positive or negative, and to a second damping rate, which is smaller than the first damping rate, when the target driving torque change amount and the target motor torque change amount have opposite positivity or negativity.

A damping control device for an electric vehicle is having a continuously variable transmission between a motor and left and right front wheels. The damping control device drive system includes a feedback control unit, which suppresses a vibration accompanying a disturbance in the rotational speed of the motor, and an operation determination unit, which determines whether or not an absolute value of a second-order differential of the transmission ratio is equal to, or greater than, a predetermined value, wherein when the absolute value of the second-order differential of the transmission ratio is equal to, or greater than, the predetermined value. The feedback control unit performs control of the output torque of the motor whereby a compensation torque component for suppressing a vibration accompanying a gear shift is subtracted from a compensation torque.

A system for controlling a motor vehicle hybrid powertrain includes a set of calculators and a switch that determine the operating point and the overall consumptions of the powertrain and a combustion engine raw torque setpoint, determine a gradient of an equivalence factor as a function of the consumptions of the powertrain, determine a crankshaft torque gradient as a function of the target torque required at the wheel and of the step-down gear ratio, determine combustion engine torque gradient minimum and maximum values as a function of the gradient of the equivalence factor, of the crankshaft torque gradient, and of look-up tables, and determine an optimal torque setpoint as a function of the raw torque setpoint and of the combustion engine torque gradient minimum and maximum values.
