The user's manipulated parameter includes at least one of a user's manipulated variable and a user's manipulated setting. In the control apparatus, a storage unit stores at least one mobility parameter that enables the driving quantity to be determined based on the user's manipulated parameter. A parameter acquiring unit acquires parameter information inputted by a user. The parameter information includes at least one of (i) a user's selected at least one mobility parameter and (ii) information related to the user's selected at least one mobility parameter.

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: 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.

Abstract: A control apparatus for a vehicle determines whether to perform either of a first control and a second control. In the first control, power is transferred between a power supply facility outside a vehicle and a power storage apparatus during stopping of the vehicle. In the second control, power is transferred between a rotating electric machine and the power storage apparatus through an inverter during traveling of the vehicle. In response to the first control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a first limit value. In response to the second control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a second limit value. The apparatus sets at least either of the first and second limit values to a value suppressing decrease in drivability of the vehicle.

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: 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: In a starter, current is passed through a solenoid to use the generated electromagnetic force when pushing a pinion gear toward a ring gear, so that the ring gear is engaged with the pinion gear. For this purpose, the starter includes an electromagnetic solenoid, a spring for urging the pinion gear in a direction opposite to that of the electromagnetic solenoid, a connecting member connected to the pinion gear, a stopper for limiting movement of the connecting member to a predetermined position. Being urged by the spring, the pinion gear is disengaged from the ring gear, and the connecting member is retracted to a predetermined position. The starter includes a control circuit that implements control of passing a predetermined current through the solenoid after the disengagement but before retraction of the connecting member to the predetermined position.
