Abstract: In an apparatus for controlling a motorized vehicle, a rotary electric machine controller is configured to perform intermittent operation by periodically alternating between a driving period and a coasting period. A torque determiner is configured to determine a first torque during the driving period and a second torque during the coasting period. A transition period determiner is configured to determine whether to set a transition period between the driving period and the coasting period. If the transition period is determined to be set, the torque determiner determines a third torque between the first torque and the second torque and within a predetermined rang. The rotary electric machine controller sets the transition period between the driving period and the coasting period and drive the rotary electric machine with the third torque during the transition period.

Abstract: A vehicle-mounted cooling system includes an air-conditioning refrigerant circuit including a refrigerant passage, a compressor, a heat source-side heat exchanger and a use-side heat exchanger, a battery, and a battery cooling unit cooling the battery using the refrigerant. A control device controls a drive state of the compressor in response to an air-conditioning request and a battery cooling request. The control device includes an abnormality determination unit configured to determine whether an abnormality has occurred in the air-conditioning refrigerant circuit, and a control mode change unit configured to perform, under a situation where the battery cooling request has occurred and it is determined that an abnormality has occurred in the air-conditioning refrigerant circuit, a change of a refrigerant-circulation control mode while permitting the battery cooling unit to continuously cool the battery based on the refrigerant, the refrigerant-circulation control mode representing how the refrigerant is circulated in the air-conditioning refrigerant circuit.

Abstract: A control apparatus for a vehicle includes processing circuitry. The processing circuitry calculates a target torque such that the greater the amount of brake operation is, the smaller the target torque becomes. The processing circuitry controls the drive motor such that the creep torque is smaller when brake operation is being performed by the driver than when the brake operation is not being performed by the driver. The control circuitry controls the brake device such that, when the brake operation is being performed by the driver, the brake torque approaches a target brake torque. The processing circuitry sets a decrease gradient of the creep torque to be smaller than a decrease gradient of the target torque when the brake operation amount is increased under a condition in which the creep torque is being output by the drive motor.

Abstract: In an apparatus for controlling a motorized vehicle equipped with a main rechargeable battery, electrical loads electrically connected to the main rechargeable battery via a voltage converter, a converter operating point setter is configured to, when current is passing between the main rechargeable battery and the electrical loads, based on a charging/discharging amount of the main rechargeable battery, set operating points of the voltage converter, each specifying a power conversion efficiency representing a ratio of input power to the electrical loads to output power of the main rechargeable battery and an output current of the voltage converter. A converter controller is configured to, based on the operating point set by the converter operating point setter, cause the voltage converter to convert the voltage of the main rechargeable battery, thereby supplying power to the electrical loads.

Abstract: A cooling control device has an inverter control unit that executes switching control of an inverter for driving a rotary electric machine, and a cooling control unit. On condition that the switching control is stopped, if it is judged that a control temperature is below a threshold value thereof, the cooling control unit executes driving and control of a cooling device such as to lower a degree of cooling of a cooling target component below the degree of cooling when it is judged that the control temperature is above the threshold value. The cooling target component is composed of at least one of the rotary electric machine and the inverter. The control temperature is either a detected temperature value of the cooling target component or an estimated temperature value from a temperature estimation unit that estimates the temperature of the cooling target component.
