When the state of charge of a battery is greater than or equal to a lower limit value and less than or equal to an upper limit value, an electronic control unit calculates a charging electric energy transferred between a motor-generator and the battery such that the battery is neither charged nor discharged. When the state of charge is less than the lower limit value, a required torque of the engine is calculated based on the charging electric energy, a power consumption of an auxiliary device, and a driving torque. When the state of charge is greater than or equal to the lower limit value and less than or equal to the upper limit value, the required torque is calculated based on the charging electric energy and the driving torque, without taking the power consumption into consideration.

Vehicle power supply device and method for controlling vehicle power supply device

A drive control section automatically stops an engine by stopping fuel injection and by closing a throttle valve that adjusts the amount of intake air when a predetermined specified condition is satisfied. A stopping-angle detection section detects a crank angle when the engine is automatically stopped as a stopping angle. The drive control section cranks the engine before an in-cylinder negative pressure period, in which pressure in a cylinder of the engine is negative pressure, elapses after starting to automatically stop the engine if the stopping angle is outside an allowable crank-angle range in which it is possible to restart the engine by cranking the engine by the motor generator.

Start controller and start controlling method

A vehicle charge control device includes a charge unit and a correction unit. The charge unit is configured to perform a charge operation for suppressing a deterioration in a battery by charging the battery until a charge end phase in which an acceptance current of the battery is smaller than a predetermined current value, the battery being mounted on a vehicle. The correction unit is configured to correct a charge rate of the battery based on a behavior of the acceptance current. In addition, the correction unit is configured to correct the charge rate based on the behavior in the charge end phase, in synchronization with the charge operation.

Vehicle charge control device to correct a state of charge

A control system of a vehicle includes an electronic control unit. The electronic control unit is configured to (a) measure characteristics of a battery installed on the vehicle, (b) determine whether the battery is a designated battery or a non-designated battery, based on at least one of the characteristics, and (c) determine whether an idling stop function of the vehicle is permitted to be executed, based on a threshold value of at least one of the characteristics of the battery. The threshold value is set to a first threshold value when the battery is determined as the designated battery, and set to a second threshold value that is different from the first threshold value when the battery is determined as the non-designated battery.

Control system and control method of vehicle

A control apparatus for a vehicle having an idle stop function includes a measurement unit that measures the characteristic of a battery provided in the vehicle, an identification unit that identifies the type of the battery based on the measured characteristic, and a control unit that stops the idle stop function in a case where the identified type of the battery indicates that the battery is not for an idle-stop vehicle, and permits execution of the idle stop function in a case where the execution of the idle stop function is permitted by an input of a predetermined signal from an external terminal even when the identified type of the battery indicates that the battery is not for the idle-stop vehicle.

Control apparatus, vehicle, and control method

A power unit is equipped with a power generator connected to an electric load, a first storage device connected to the electric load and the power generator, a second storage device connected to the electric load, the power generator, and the first storage device, and a charge control device that controls charge/discharge of the second storage device. The charge control device controls the discharge of the second storage device such that a power is supplied to the electric load and the first storage device when a predetermined condition corresponding to a high possibility of an increase in a power generation amount of the power generator is fulfilled, and controls the discharge of the second storage device such that a power is supplied to the electric load when the predetermined condition is not fulfilled.

Charge control device controlling discharge of power

A current density changing portion is formed in a heating process on an upper base side with respect to a center portion of a flat metal plate in a direction of current flow, by passing current from a lower base side to the upper base side of the flat metal plate which is rectangular when viewed from above. As a result, a quenchable portion is formed on the upper base side with respect to the center portion of the flat metal plate in the direction of current flow, and a non-quenchable portion is formed on the lower base side with respect to the center portion of the flat metal plate in the direction of current flow. The flat metal plate is press-formed after the heating process, so a complex die cooling structure is not necessary during press-forming, which enables the die cost to be reduced.

Press-forming method and press-formed part

A driving force controlling apparatus for a vehicle including an electric generator and a motor for driving a wheel other than a driving wheel, with electric power from the electric generator, includes a requested electric power computing means that computes requested electric power required for operation of the motor. Target output of the electric generator is set based on the requested electric power and maximum output that the electric generator can output stably. The driving force controlling apparatus for a vehicle including the motor for driving a wheel other than a driving wheel driven by an engine, with electric power from the electric generator, enables the electric generator to stably output electric power.

Driving force controlling apparatus for vehicle

A vehicle driving apparatus that can execute cranking of an internal combustion engine by transmitting a mechanical power from a rotor of a motor to an engine output shaft without executing an engaging/disengaging operation of a clutch. A driving apparatus of a hybrid vehicle includes a first speed change mechanism capable of receiving mechanical power from an engine output shaft by a first input shaft and transmitting the mechanical power to drive wheels, a second speed change mechanism capable of receiving the mechanical power from the engine output shaft and a rotor by a second input shaft engaged with the rotor and transmitting the mechanical power to the drive wheels, a first clutch capable of engaging the engine output shaft with the first input shaft, and a second clutch capable of engaging the engine output shaft with the second input shaft.

Vehicle driving apparatus

A driving apparatus includes a first transmission mechanism receiving mechanical power from an engine output shaft by a first input shaft, a second transmission mechanism receiving the mechanical power from the engine output shaft and a motor by a second input shaft, and a first clutch capable of engaging the engine output shaft with the first input shaft. When performing cranking of an internal-combustion engine, an ECU selects a gear position of the first transmission mechanism and the second transmission mechanism to reduce speed of the mechanical power received by the second input shaft and transmit the power to the first input shaft, and puts the first clutch into an engaging state. The speed of the mechanical power from the motor is reduced by the first and second transmission mechanisms to increase torque, and power is transmitted to the engine output shaft through the first clutch.

Driving apparatus for vehicle

During a starting operation or a low-speed drive of a vehicle on a slope, the drive control of the invention sets a gradient-corresponding rotation speed N&#x3b8; as a rotation speed of an engine to output a required driving force against a longitudinal vehicle gradient &#x3b8;fr (step S), and sequentially sets a low-&#x3bc;-road correction rotation speed Nlow upon identification of a low-&#x3bc;-road drive condition, a vehicle speed difference-compensating rotation speed Nv based on a vehicle speed V, and a brake-based correction rotation speed Nb based on a brake pressure Pb (steps Sthrough S). The drive control sets a target engine rotation speed Ne* based on these settings (step S) and subsequently sets a target throttle opening THtag (step S). The operation of the engine is controlled with the greater between the target throttle opening THtag and a required throttle opening THreq corresponding to an accelerator opening Acc (step S). This arrangement effectively prevents an unexpected slide-down of the vehicle along the slope.

Motor vehicle and control method of motor vehicle

When a driver returns a brake pedal on a climbing road, brakes of front wheels to which power is output from an engine with brakes of rear wheels being held are released (S), and a throttle opening TH is gradually increased so that a rotation speed of the engine reaches a target rotation speed Ne* according to a road gradient &#x3b8; (S). When an outputtable torque Tem that can be output to the front wheels and the rear wheels becomes larger than a target torque Td* according to the road gradient &#x3b8;, the brakes of the rear wheels are released (S) to start a vehicle. This allows a smooth start of the vehicle on the climbing road. On the other hand, when a slip of the front wheels is determined before the outputtable torque Tem reaches the target torque Td*, the brakes of the front wheels are returned to the original state, climbing road start control is prohibited (Sand S), and a stopping state is held. This properly addresses the problem when the vehicle cannot smoothly start.
