Systems and methods described herein relate to managing the freshness of the fuel in a vehicle. One embodiment tracks a freshness level of the fuel in the vehicle as time passes; determines a fuel consumption plan based, at least in part, on a predetermined refueling schedule for the vehicle and the freshness level of the fuel in the vehicle; and activates an internal combustion engine of the vehicle automatically on one or more occasions in accordance with the fuel consumption plan to consume at least a portion of the fuel.

A vehicle controller for use with a vehicle is configured to control the vehicle. The vehicle includes an internal combustion engine, an electric generator, an auxiliary machine, an electricity storage device, and a DC-DC converter. The controller is configured to execute an automatic stop process of stopping combustion control of the internal combustion engine in response to an automatic stop request of the internal combustion engine, and an increase process of operating, when the automatic stop process is executed, the DC-DC converter to increase an amount of electricity supplied to the electricity storage device, thereby increasing an electricity generation amount of the electric generator.

On satisfaction of conditions to shift to scavenging control in response to a stop request of an engine, a hybrid vehicle performs engine power limitation control that limits the power output from the engine with an engine upper limit power as an upper limit.

Disclosed are a system and method for remotely controlling and monitoring a vehicle based on the IoT. A system for remotely controlling and monitoring a vehicle based on an IoT includes a communication unit configured to receive a remote control signal and an event signal and transmit monitoring information, a gear mode sensing unit configured to sense a gear mode, a control unit configured to generate a start-up control signal for a vehicle in response to the remote control signal or the event signal, output or stop a start-up control signal in response to a gear mode, output a monitoring signal when start-up is performed, perform transmission control through the communication unit by generating the monitoring information, generate and output an associated vehicle control signal in response to an event, and a start-up device configured to be turned on in response to the start-up control signal.

An automotive electronic control unit is configured to: determine the current operation status of an automotive dual battery electrical system defined by the current electric charge statuses of a main electrical energy source and of an auxiliary electrical energy source and by the current electrical energy demand of electrical loads, determine which operation area of an operation plane of the automotive dual battery electrical system the current operation status of the automotive dual battery electrical system belongs to, and control the operation of the automotive dual battery electrical system, and enable or disable the implementation of one or more of the functionalities of automatic start and stop of the internal combustion engine, of regenerative braking and of electric charging depending on the operation area which the current operation status of the automotive dual battery electrical system belongs to.

In a vehicle control method, when drive force which a second electric motor is requested to output increases in a state where an internal combustion engine is stopped, drive force which the second electric motor outputs by using electric power supplied by a battery is limited to a lower level than maximum drive force determined from electric power which can be supplied by the battery to drive an electric-powered vehicle. Then, the drive force which the second electric motor outputs by using the electric power supplied by the battery is increased over time in a period from when the second electric motor outputs the drive force limited to the lower level to when the internal combustion engine is fired up and a first electric motor starts power generation.

A vehicle includes an engine, a motor, and a controller. The engine and motor are each configured to deliver torque to a torque converter impeller. The controller is programmed to, responsive to a demanded impeller torque exceeding an upper motor torque threshold while the motor alone is delivering torque to the impeller, increase motor torque to a value that is less than the threshold and that depends on a torque converter bypass clutch torque capacity and a torque converter turbine speed.

Apparatuses, systems, methods, and techniques relating to engine start/stop functionality are disclosed. Automatic engine start/stop controls can be disabled during engine operating conditions in which one or more combustion parameters indicate a lack of combustion stability in one or more cylinders of the engine. Engine start/stop controls are enabled when the one or more combustion parameters satisfy combustion parameter conditions indicating combustion stability in the one or more cylinders.

Methods and systems are provided for controlling engine operation in a hybrid electric vehicle equipped with stop/start capabilities under conditions where requested power or torque is in a hysteresis region between an engine pull up threshold and an engine pull down threshold. In one example, a method comprises obtaining an adjusted engine pull down threshold upon the requested power or torque remaining in the hysteresis region for more than a threshold duration, and commanding the engine deactivated in response to the adjusted engine pull down threshold being equivalent to the requested power or torque. In this way, a motor/generator may be used to meet the requested torque response rather than the engine under such conditions, which may improve fuel economy.

When it is determined that control of warm-up of a catalyst is necessary at the time of start of an engine, an ECU starts warm-up control. Initially, the ECU performs first processing for a first set time period. In the first processing, the ECU sets the engine to an idle state and fully opens a waste gate valve. When the first set time period has elapsed since the first processing was started, the ECU performs second processing. In the second processing, the ECU sets the engine to a prescribed rotation speed and fully closes the waste gate valve. When a second set time period has elapsed since the second processing was started, the ECU quits the second processing and quits warm-up control.
