A vehicle information display control device includes: an automatic driving information obtaining unit that obtains automatic driving information including information indicating that each actuator of a vehicle is in a manual control mode or an automatic control mode; and a display controller that displays images on a first display area and a second display area of a display based on the automatic driving information. The display controller displays an image corresponding to an actuator in the manual control mode on the first display area and an image corresponding to an actuator in the automatic control mode on the second display area.

In a controller of an internal combustion engine equipped with an electric supercharger driven by a motor, an object is to attempt to improve fuel consumption of a vehicle. The controller includes an electric supercharger driven by a motor; a generator that performs power generation using the output of the internal combustion engine as power; a charging device which is charged by the generator and can store electricity; and an accelerator opening degree detector that detects an accelerator opening degree. In the controller, a configuration is made such that, the controller controls supply electricity to the electric supercharger and generated electricity by the generator by the output of the accelerator opening degree detector, output needed for the electric supercharger calculated depending on the accelerator opening degree, and an state of charge in the charging device.

A power supply device for a vehicle has connection changeover means for alternatively changing a connection of a capacitor and a battery over to any one of a parallel connection of the capacitor and the battery, a series connection of the capacitor and the battery and an independent connection of the capacitor and the battery. Electrical power is selectively supplied to a electric supercharger by any one of a parallel connection circuit of the capacitor and the battery, a series connection circuit of the capacitor and the battery and an independent connection circuit of the capacitor and the battery whose connection of the capacitor and the battery are alternatively changed over to by the connection changeover means.

An object is to provide a vehicle control apparatus capable of enhancing fuel economy when coasting is performed by disconnecting a clutch disposed between an engine and drive wheels of the vehicle. A travel path and a travel pattern of a vehicle are predicted by a vehicle outside information collection device, such as a navigation system. Also, amounts of fuel consumption by normal traveling and coasting are predicted and compared, so that coasting control is performed in a case where an amount of fuel consumption can be reduced by performing the coasting control.

Vehicle control apparatus

Internal combustion engine system includes an electric supercharger which supercharges sucked air; a throttle valve which adjusts the flow amount of intake air of supercharged air into a cylinder; an EGR path in which a part of exhaust gas exhausted from the exhaust manifold side is recirculated to the intake manifold side; an EGR valve which adjusts the amount of exhaust gas passing through the EGR path; and an internal combustion engine control unit which controls the throttle valve, the EGR valve, and the electric supercharger. This enables to satisfy both performance of the supercharger and fuel consumption of the internal combustion engine without complicating the structure of EGR.

The control device for a hybrid vehicle including an exhaust-gas driven generator includes: a turbine (); an exhaust-gas driven generator (); a motor generator (); a battery (); and a control unit () for performing overall control based on a result of reading of a status signal. When the control unit determines based on the result of the reading of the status signal that an output of the internal combustion engine is required to be assisted by the motor generator, the control unit further determines whether a power generation by the exhaust-gas driven generator is in an inhibited state or an allowed state. When the control unit determines that the power generation by the exhaust-gas driven generator is in the inhibited state, the control unit stops the power generation by the exhaust-gas driven generator to drive the motor generator by the power from the battery.

Provided is an internal combustion engine for improving fuel-economy performance in any of the case where supercharging performed by an electric supercharger is required and the case where the supercharging is not required. The internal combustion engine includes: an electric supercharger; a supercharger; an electric motor; and a controller, the electric supercharger being for compressing an intake air by rotation of the supercharger caused with rotation of the exhaust turbine by an exhaust gas energy to perform supercharging and for rotationally driving the supercharger with electric-motor assistance by the electric motor; an exhaust bypass passage provided to bypass the exhaust turbine; and an opening and closing the exhaust bypass passage unit. In the internal combustion engine, the opening and closing the exhaust bypass passage unit opens the exhaust bypass passage until the supercharging is started by the electric supercharger.

An on-off switch is provided between a first battery acting to supply an electric power to on-vehicle electrical equipment and a second battery acting to supply an electric power to an electric supercharger. In the case that charge voltage of the first battery is smaller than a predetermined value and operating power of an electric superchargeris larger than a predetermined value, the on-off switch is opened to suppress electrical effects on the on-vehicle electrical equipment. In other cases, the on-off switch is closed and the second battery is charged by a generator and the first battery. As a result, it is possible to suppress adverse effects on the on-vehicle electrical equipment due to voltage drop or voltage fluctuation of a power source occurring by driving the electric supercharger and thus to make a stable power supply.
