Abstract: A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected at least one of driving modes. The driving modes include a low-gear all-wheel driving mode and a high-gear all-wheel driving mode. In a case in which the low-gear all-wheel driving mode is selected in the high-gear all-wheel driving mode when the engine is in a stopped state with a vehicle power transmission apparatus being in a non-driving position that disables transmission of a drive power, the engine control portion maintains the stopped state of the engine until completion of switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode, and starts the engine after the completion of the switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode.

Abstract: A fuel cell system according to one embodiment performs refresh control of an electrode catalyst of a fuel cell, by reducing a stack voltage as a voltage of the fuel cell to a refresh voltage at which the electrode catalyst is activated. The system includes the fuel cell that generates electric power by an electrochemical reaction using fuel gas and oxidation gas, a stack voltage sensor that sensors the stack voltage, and a controller that controls power of the fuel cell. When a high load demand that makes the stack voltage lower than a given voltage is made on the fuel cell, the controller causes the fuel cell to deliver power commensurate with the high load demand, and performs refresh control when the stack voltage becomes lower than the given voltage through the above control.

Abstract: A control apparatus for a vehicle that includes an engine as a drive power source, a rotating machine as an electric power generator, and an electric storage device. The control apparatus executes an automatic drive control for automatically controlling a torque of the drive power source in accordance with a requested drive torque without requiring an acceleration/deceleration operation by a driver of the vehicle. During an engine running of the vehicle, the rotating machine is rotated by the engine to generate an electric power, and a charging amount, by which the electric storage device is to be charged, is controlled by controlling the electric power generated by the rotating machine. The control apparatus is configured, during an automatic driving of the vehicle, to set the charging amount such that the charging amount is smaller when the requested drive torque is small than when the requested drive torque is large.

Abstract: A control apparatus for a hybrid electric vehicle includes: an engine control portion configured to control an operation state of an engine in accordance with an engine operation condition; and a driving-mode control portion configured to control the vehicle so as to realize selected at least one of driving modes. The driving modes include a towing mode in which the vehicle tows a towed vehicle, a main-drive-wheel driving mode in which a drive power is distributed to main drive wheels, and an all-wheel driving mode in which the drive power is distributed to the main drive wheels and auxiliary drive wheels. The engine operation condition is determined such that an engine operation ratio is higher in a case in which the towing mode is selected, than in a case in which the all-wheel driving mode is selected without the towing mode being selected.

Abstract: In a hybrid vehicle including an engine, a motor driven by a battery output, and a continuously variable transmission, when acceleration is requested, an ECU executes feeling-of-acceleration producing control for gradually increasing an engine rotation speed from an initial value NEini lower than an optimum rotation speed. With the battery output, the ECU makes up for a shortfall of engine output caused by the feeling-of-acceleration producing control. When starting the feeling-of-acceleration producing control, the ECU calculates a basic initial value NEini_base lower than the optimum rotation speed, and calculates, based on an atmospheric pressure, a lower limit value NEmin that allows the battery output to be maintained to be equal to or lower than prescribed electric power. The ECU selects a larger one of basic initial value NEini_base and lower limit value NEmin as initial value NEini.
Abstract translation: 在包括发动机，由电池输出驱动的电动机和无级变速器的混合动力车辆中，当要求加速时，ECU执行感觉加速度生成控制，以从初始值NEini下降逐渐增加发动机转速 比最佳转速。 通过电池输出，ECU弥补了由加速感产生控制引起的发动机输出不足。 当开始加速感觉产生控制时，ECU计算低于最佳转速的基本初始值NEini_base，并且基于大气压计算允许将电池输出保持为的下限值NEmin 等于或低于规定的电力。 ECU选择基本初始值NEini_base和下限值NEmin中较大的一个作为初始值NEini。

Abstract: A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected driving mode or modes. The driving modes include a main-drive-wheel driving mode in which a drive power is distributed to main drive wheels, and an all-wheel driving mode in which the drive power is distributed to the main and auxiliary drive wheels. When the all-wheel driving mode is selected in the main-drive-wheel driving mode with the engine being in a stopped state, the engine control portion is configured to maintain the stopped state of the engine until completion of switching from the main-drive-wheel driving mode to the all-wheel driving mode, and to start the engine after a predetermined operation is executed by the driver of the vehicle to drive the vehicle.

Abstract: A vehicle includes an engine, a second MG for running, a battery that supplies and receives electric power to and from the second MG, and an ECU. The ECU is configured to control the engine and the second MG and to execute intake air amount learning. When the SOC of the battery exceeds a second threshold value that is higher than a first threshold value while the vehicle is running using the second MG with the engine in a stopped state, the ECU maintains the engine in the stopped state and maintains the second MG in a driven state, and then does not execute the intake air amount learning. When the SOC of the battery takes a value between the first threshold value and the second threshold value, the ECU starts the engine, drives the second MG with constant torque, and executes the intake air amount learning.

Abstract: An amount of electric power generated by a power supply device is input, an upper-limit current value is calculated using a relationship which varies with operation of the conversion circuit, a lower-limit voltage of the conversion circuit is calculated based on the amount of generated electric power and the upper-limit current value, and control is performed such that a voltage on an output side of the conversion circuit is higher than the lower-limit voltage. Accordingly, even when a voltage conversion device restricts a current output from the conversion circuit, it is possible to curb an influence on an output of the power supply device.

Abstract: A fuel cell system of the present disclosure performs a first and a second catalyst activation process, and the first catalyst activation process is performed where a flow rate of the air supplied to the fuel cell by the air compressor is reduced to be less than that before the refresh control is performed while keeping an amount of a current drawn from the fuel cell by the fuel cell converter at the same value as that before the refresh control is performed, and the second catalyst activation process is performed where the value of the current drawn from the fuel cell by the fuel cell converter is increased to be greater than that before the refresh control is performed while keeping the flow rate of the air supplied to the fuel cell by the air compressor at the same value as that before the refresh control is performed.
