Disclosed are a vehicle control unit (VCU) and an operation method thereof that calculate a speed variation of a vehicle based on input information, predict an average speed of the vehicle based on the calculated speed variation, generate a first speed profile based on the predicted average speed, and generate a second speed profile by applying speed noise information to the first speed profile.

A vehicle is provided and includes a GPF (gasoline particulate filter) that is configured to store a soot generated in an engine and burn the soot and a sensor that is configured to detect a first soot mass included in the GPF. A controller is configured to calculate a second soot mass estimated at the ignition off based on the detected first soot mass and determine an inlet temperature of the GPF based on the second soot mass and a predetermined reference value. The engine is then operated based on the determined inlet temperature of the GPF.

An electronic control unit to control an engine control module of an engine is disclosed. The electronic control unit may receive, from a load monitoring device, power command information associated with a load of an engine. The electronic control unit may determine, based on the power command information, a total power command of the engine. The electronic control unit may determine, based on the total power command, a target engine speed for the engine. The electronic control unit may cause an engine control module to control the engine to operate in association with the target engine speed.

Upon determining that a vehicle is operating within an area, a stop time for the vehicle in the area is estimated based on operation data from an infrastructure element in the area. A vehicle sensor that is available to transition to a low power mode is identified based on the estimated stop time. Upon stopping the vehicle in the area, the available vehicle sensor is transitioned to the low power mode based on the estimated stop time being greater than a threshold.

To provide a technique for reliably acquiring a required braking power during travel and for efficiently using a regenerative power generated during braking. A work vehicle calculates a regenerative power outputted from an electric motor and a target hydraulic driving power for driving a hydraulic pump, supplies the regenerative power to the generator motor operating as a motor and makes the generator motor consume the regenerative power in a case where the regenerative power is equal to or smaller than the target hydraulic driving power, and supplies the regenerative power to the generator motor operating as the motor and makes an exhaust brake consume a power equivalent to a difference between the regenerative power and the target hydraulic driving power in a case where the regenerative power is larger than the target hydraulic driving power.

Provided is a travelable distance display apparatus that can accurately estimate a travelable distance of an electric vehicle and display the travelable distance according to the state of use of the electric vehicle.

A travelable distance display apparatus 60 mounted on an electric vehicle 10 having a battery 40 for supplying travel power includes a travelable distance calculation device 62 and a display device 65. The travelable distance calculation device 62 calculates a travelable distance of the electric vehicle 10 based on the average speed of the electric vehicle 10 and the power consumption of an air-conditioning apparatus 80 mounted on the electric vehicle 10. The display device 65 can display the travelable distance of the electric vehicle 10 in a case where each of the average speed of the electric vehicle 10 and use/non-use of the air-conditioning apparatus 80 is changed.

Methods and systems are provided for extending a duration of engine idle-stop while reducing a frequency of engine restart from idle-stop. In one example, in response to engine restart conditions where combustion torque is not necessary, an engine can be rotated electrically, without fuel delivery, via an electric motor. The unfueled engine spinning via the motor drives an FEAD which in turns drives an actuator coupled to the FEAD, such as an AC compressor or an automatic transmission oil pump.

An apparatus of controlling a hybrid vehicle may include: an engine configured to an engine power; a drive motor to assist the power of the engine and selectively operate as a generator to generate electrical energy; a clutch disposed between the engine and the drive motor; a battery to supply electrical energy to the drive motor or to be charged by the electrical energy generated by the drive motor; an electric supercharger installed in an intake line through which an ambient air is supplied to a combustion chamber of the engine; and a controller to operate the electric supercharger and control the engine power output from the engine and a drive motor power output from the drive motor based on a desired power of a driver and a SOC (state of charge) of the battery.

A prime mover and a method for operating a prime mover are disclosed. The prime mover, which may be a tractor, includes a drivetrain and is configured to attach to an attachment. The drivetrain includes at least one drive motor, a gearbox, at least one power take-off, and at least one ancillary unit. The prime mover has a driver assistance system that controls the drivetrain and that includes a computing unit, a memory unit, and an input/output unit. The driver assistance system comprises an engine droop governor that works based on a characteristic curve, wherein the engine droop governor is configured for optimized control of the drivetrain depending on selectable control strategies saved in the memory unit and/or optimization target variables.

A hybrid vehicle using an engine driving a generator to supply power to electric drive motors through a system power bus, and a method for controlling power regeneration in a hybrid vehicle are disclosed. Ground drive controllers associated with the drive motors are configured to determine a slope of a surface on which the vehicle is driving and set a maximum downhill speed of the vehicle based thereon. A generator controller, in response to the drive motors generating power through regenerative braking, regulates power on the bus by directing the generated power to recharge the battery when the battery has capacity, reducing an output of the generator to the bus when the battery is fully charged, and driving a driveshaft to drive the engine with the generator to consume excess power on the bus when the generator output is reduced to zero.
