The present invention controls torque of a hybrid vehicle that calculates power and torque of each motor when the hybrid vehicle provided with two motors operates at a transient state are used. More specifically, target power of a battery is determined. Then calculations are performed to determine target torque of the first motor, target torque of the second motor, target torque of an engine, and target speed of the engine at a steady state. The torque of the first motor at a transient state is calculated from the target torque of the second motor at the steady state and speeds of the first and second motors. Finally, torque of the second motor at the transient state is calculated from the torque of the first motor at the transient state and the speeds of the first and second motors.

Location information may be used to adjust the engine start/stop characteristics of a hybrid electric vehicle (HEV) in order to increase the amount of electric vehicle (EV) mode driving, particularly near a destination in which an ignition-off event may occur. Common ignition-off locations may be learned and stored in a database along with the number of ignition-off occurrences associated with each learned location. The vehicle may calculate current distance to a nearest ignition-off location stored in the database using positioning system coordinates and may determine whether to adjust one or more engine pull-ups based at least in part on the distance and the corresponding number of ignition-off occurrences.

Motor traveling using only an output of a rotating electrical machine utilizing power of a vehicle-mounted power storage device is applicable to an electrically-powered vehicle, within a region inside a maximum output line in motor traveling. The maximum output line is composed of straight line portions defining an upper limit torque and an upper limit vehicle speed and a curved line portion defining upper limit output power, in motor traveling. When an output power upper limit value from the power storage device is limited due to an increase in a current load or a reduction in the SOC of the power storage device, a driving region to which motor traveling is applicable is narrowed.

When the actuator drive torque of a hydraulic pump is lower than a switching torque τ0, a controller closes a solenoid switching valve and makes a rotary electric machine function as a generator. With the increase in the actuator drive torque, the controller controls a pressure compensated flow control valve so that the flow rate of hydraulic fluid supplied from the hydraulic pump to a rotary hydraulic device decreases. When the actuator drive torque is higher than the switching torque, the controller opens the solenoid switching valve, makes the rotary electric machine function as an electric motor, and controls the pressure compensated flow control valve so that the hydraulic fluid discharged by the hydraulic pump is not supplied to the rotary hydraulic device. Consequently, shocks due to flow rate fluctuation are prevented when operational states of the rotary hydraulic device and the rotary electric machine are switched. 1.

Provided are a vehicle, control method, and computer program with which reliable starting is possible without modifying hardware. When a clutch is disconnected, an inverter determines whether the time period in which the absolute value of the rotational speed of a motor becomes a predetermined first threshold or less and the torque of the motor becomes a predetermined second threshold or greater has continuously equaled or exceeded a predetermined third threshold. When the clutch is disconnected and it is determined that the time period in which the absolute value of the rotational speed of the motor becomes the predetermined first threshold or less and the torque of the motor becomes the predetermined second threshold or greater has continuously equaled or exceeded the predetermined third threshold, an HV-ECU controls the motor to restrict the torque of the motor and also controls the clutch to connect the clutch.

The disclosed vehicle smoothly generates the torque requested by the driver. The vehicle includes an elapsed time measurement unit, a torque limit value deciding unit, and an electric motor torque control unit. The elapsed time measurement unit measures the time elapsed since the vehicle has started moving in an EV mode, in which travel or starting is performed only with the drive force of an electric motor. The torque limit value deciding unit decides a torque limit value of the electric motor by means of the time elapsed since starting and the acceleration opening amount originating from the driver's instructions. The electric motor torque control unit controls the electric motor so as to limit the torque of the electric motor to or below the limit value. The disclosed control method can be used in hybrid vehicles.
