Disclosed is a method of controlling a hybrid electric vehicle having a transmission, an engine, and first and second drive motors. The method includes: performing charging through the first drive motor using the power of the engine by engaging an engine clutch disposed between the engine and the first drive motor while a vehicle is stopped with the gear stage shifted to the parking (P) range; turning off the engine and controlling the clutch of the transmission to enter an open state when the gear stage is shifted to the driving (D) range; and commencing movement of the vehicle using the second drive motor alone or using at least one of the first drive motor or the engine together with the second drive motor based on at least one of requested torque, available torque of the second drive motor, or the speed of the first drive motor.

A method to control a road vehicle provided with a dual-clutch, servo-assisted transmission and standing still with the internal combustion engine turned on; the control method generally includes, when the road vehicle is standing still with the internal combustion engine turned on, the steps of: engaging a forward gear associated with a first clutch; engaging a reverse gear associated with a second clutch, which is different from and independent of the first clutch; closing the first clutch so as to cause the first clutch to transmit a first torque; and closing the second clutch so as to cause the second clutch to transmit a second torque, which is equal to the first torque multiplied by the quotient between a gear ratio of the reverse gear and a gear ratio of the forward gear.

In an operating method for an emergency vehicle, especially a fire truck, having a vehicle body, a drive unit having a drive motor and a motor controller, front-wheel and rear-wheel pairs, an emergency aggregate, a signaling device, an illuminating device, and a mode-of-operation controller having a mode-of-operation selector switch having selectable operation modes and a memory with saved operating-data sets, by a sequence controller of the mode-of-operation controller, selecting a first operation mode corresponding to an emergency trip transmits from the memory to the target systems, and activates, first operating-data data sets. Selecting a second operation mode corresponding to an emergency mode deactivates the transmitted first operation mode operating-data sets, and transmits from the memory to the target systems, and activates, second operating-data sets. Selecting a third operation mode corresponding to a standard operation mode deactivates the transmitted data sets of the first, second or any further operation modes.

A coasting driving control method and system for a vehicle may determine virtual engine RPM for a current driving state using engine RPM, vehicle speed, and gear stage information by a controller when coasting is started with the clutch in the neutral position and outputs a downshifting instruction signal for a gear stage by the controller when the virtual engine RPM is less than a coasting engine RPM which is greater than an idling RPM by a predetermined value.

A charge control system for a vehicle, which is configured to control charging of a power storage device, includes a user detector that determines whether a user is present within a predetermined range relative to the vehicle, and a vehicle electronic control unit configured to permit the power storage device to be charged with electric power generated by the generator, in addition to the power from the outside of the vehicle, during external charging, when the user detector determines that the user is present within the predetermined range. The vehicle ECU is configured to inhibit power generation by the generator during external charging when the user detector determines that the user is not present within the predetermined range.

A vehicle includes an accelerator pedal, a brake pedal, an electric machine, friction brakes, and a controller. The electric machine is configured to propel the vehicle and to brake the vehicle during regenerative braking. The friction brakes are configured to brake the vehicle. The controller is programmed to, responsive to an operator selection of a one-pedal drive mode, decrease vehicle speed via regenerative braking in response to releasing the accelerator pedal. The controller is further programmed to transition the vehicle to an inhibit state in which the friction brakes are applied to prevent vehicle creep in response to receiving an automated signal to disable the one-pedal drive mode and vehicle speed becoming zero while the one-pedal drive mode is selected.

A method and a system for a vehicle comprising: one or more power sources including at least one electrical machine; and a drivetrain for transferring torque between the one or more power sources and at least one drive wheel of the vehicle. The method comprises: controlling, when no positive drive torque (T.sub.drive) is transferred from the drivetrain to the at least one drive wheel, the at least one electrical machine to provide a backlash torque (T.sub.backlash) to the drivetrain, the backlash torque (T.sub.backlash) having a controlled value for turning the drivetrain if there is a backlash present in the drivetrain.

Techniques are provided for generating a driving trajectory for a vehicle while the vehicle is blocked (e.g., the sensor of the vehicle have detected an object results in the vehicle being unable to move) by an object (e.g., another vehicle, bicycle, or a pedestrian) and executing the driving trajectory when the vehicle becomes unblocked. In addition, techniques are provided for updating a portion of a driving trajectory of a vehicle based on a determination that an object will cross a segment of the current driving trajectory at a later point, without recalculating the whole trajectory.

A plug-in hybrid electric vehicle capable of achieving a charging target in response to environmental change via a charging control method. The charging control method includes: setting reserved charging using external power based on a departure time and a target state of charge (SOC) of a battery; monitoring whether change in charging environment has occurred, determining whether the target SOC of the battery is capable of being achieved at a currently set departure time, when the charging environment has been changed; and performing series charging using an engine and a motor upon determining that the target SOC of the battery is incapable of being achieved.

The powertrain device for a vehicle includes an engine and an automatic transmission, the automatic transmission includes a plurality of friction fastening elements for selectively switching motive power transmitting paths, a predetermined friction fastening element among the plurality of friction fastening elements is a travel-start friction fastening element performing slip control in a travel start, and the powertrain device includes, between the engine and the automatic transmission, a motive power connection-disconnection clutch which is released at least in an engine start and is fastened earlier than the travel-start friction fastening element in a travel start of the vehicle.
