Systems and methods for improving operation of a driveline disconnect clutch for a hybrid vehicle shifting are presented. In one example, pressure of a working fluid supplied to the driveline disconnect clutch is adjusted in response to a rate of change in accelerator pedal position. Further, pressure of the working fluid may be decreased responsive to selected operating conditions.

A vehicle failure warning system is disclosed that is in communication connection with a plurality of vehicles and is capable of warning the vehicles of an imminent failure.

A method for operating a motor vehicle. At least one electric engine designed for driving the motor vehicle is used to recuperate electric energy. In this case, a travel of the motor vehicle during a period of time lying ahead is taken into account. During the use of at least one electric engine for recuperating the electric energy, it is taken into account whether during a thermal load of the at least one electric engine in the period lying ahead, a reduction of the power that can be output by at least one electric engine is to be expected. The at least one electric engine then recuperates an amount of electric energy during the deceleration of the motor vehicle which is smaller than the amount of electric energy that can be recuperated during the deceleration by the at least one electric engine. The invention relates in addition also to a motor vehicle.

A control unit of a vehicle, which is configure to travel in a first traveling mode in which power outputted from an electric motor according to electric power supplied from a generator and an electric storage device is used and in a second traveling mode in which power outputted from an internal combustion engine and the electric motor according to the electric power supplied from the electric storage device is used, includes: a vehicle speed acquisition unit; a driving force acquisition unit configured to acquire a driving force in the first traveling mode according to a vehicle speed and a driving force in the second traveling mode according to the vehicle speed; and a traveling mode control unit configured to drive the vehicle in the traveling mode capable of obtaining a large driving force at the vehicle speed based on a comparison result of the driving forces.

Since a maximum rotation speed is set to a lower value when a supercharging pressure from a supercharger is high than when the supercharging pressure is low, an engine torque is decreased at a relatively low engine rotation speed and the engine rotation speed is less likely to fall into a high-rotation state. Since the maximum rotation speed is set to a relatively high value when the supercharging pressure is relatively low and the engine rotation speed is less likely to fall into a high-rotation state, the engine torque is not decreased at a relatively high engine rotation speed and power performance can be easily secured. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the engine torque and to prevent the engine rotation speed from falling into a high-rotation state.

An apparatus for controlling an environment-friendly vehicle, a system having the same, and a method thereof are provided. The apparatus includes a processor to perform a control operation to expand an operable area based on a motor efficiency gain and a state of charge (SOC) of a battery in an Homogeneous Charge Compression Ignition (HCCI) operation or a lean burn operation, and a storage to store the motor efficiency gain and the SOC of the battery, which are acquired by the processor.

The drive control system includes an actuator configured to output a driving force for the vehicle to travel, an output sensor configured to detect a driving force requested by the operation of the driver, and a control device configured to control operation of the actuator based on the requested driving force detected by the output sensor. The control device sets a target output value by adding a given delay time to a requested output value set corresponding to the requested driving force, and controls the actuator so as to output the target output value based on a response characteristic of the actuator.

A vehicle includes a first rotary electric machine, a second rotary electric machine, and a control circuit.
