The driving force control device for a hybrid vehicle comprises a PCM configured to: identify a vehicle acceleration; estimate an average torque output by an engine; estimate a torque fluctuation component of the torque output by the engine; set a countertorque for suppressing the estimated torque fluctuation component; and control an electric motor to output the set countertorque, wherein the PCM is operable, under a condition that an engine speed and the average torque output by the engine are constant, to set the countertorque such that, as the absolute value of the vehicle acceleration becomes smaller, the absolute value of the countertorque becomes larger.

A method to control a road vehicle during a slip of the drive wheels, which are caused to rotate by an internal combustion engine provided with a plurality of cylinders arranged in two banks, and with a plurality of fuel injectors each injecting fuel into a corresponding cylinder. The control method comprises the steps of: detecting a slip of at least one drive wheel; and controlling the internal combustion engine, only during a slip of at least one drive wheel, with a signalling law, which causes the internal combustion engine to work in an abnormal manner so as to generate an abnormal vibration and/or an abnormal noise, which can be perceived by the driver. The internal combustion engine has two twin control units, each of which is associated with a corresponding bank, controls all and the sole injectors of its own bank and actuates the signalling law completely independently of and autonomously from the other control unit.

A park brake system for adjusting a tension in a brake cable that is coupled to a park brake. The park brake system can include a driver that is communicatively coupled to a microcontroller, and an actuator that is rotatably displaceable by operation of the driver. An equalizer assembly can be linearly displaced along the rotating actuator to adjust a tension in the brake cable. The microcontroller can monitor a current being drawn by the driver as the driver is operated, and generate instructions to cease operation of the driver upon the current reaching a predetermined current threshold that corresponds a maximum force that is to be applied by the park brake. The microcontroller can also, when the park brake is being released from a set position, count pulses outputted by an encoder in connection with determining whether the park brake has reached a running clearance position.

A powertrain system is described, and includes an internal combustion engine and an electric machine configured to generate propulsion torque responsive to a driver torque request.

A motor control device according to an embodiment includes a hardware processor configured to: calculate a first torsion torque generated by a motor shaft according to fluctuation of an engine torque based on a difference between a motor angle as a rotation angle of the motor shaft and a shaft angle as a rotation angle of a transmission shaft of a transmission on the downstream side of a damper; calculate a first vibration damping torque to be output by a motor generator to damp vibration of the motor shaft based on the first torsion torque and a drive state value indicating a drive state of an engine; and output a motor torque command value to be provided to the motor generator based on the first vibration damping torque.

A hybrid vehicle controller includes processing circuitry configured to execute a particulate matter (PM) deposition amount estimation process that estimates a deposition amount of PM deposited in the filter. The processing circuitry is configured to switch between a first mode and a second mode as a control mode that defines control of the engine and the motor. A use of the engine is limited in the first mode as compared with the second mode. The processing circuitry is configured to execute a display process that notifies a user that the filter needs to be regenerated when the control mode is the second mode if the estimated deposition amount is greater than or equal to a predetermined amount, and not to execute the display process when the control mode is the first mode even if the deposition amount is greater than or equal to the predetermined amount.
