    摘要： An exhaust brake torque system for a vehicle including an engine includes a controller configured to determine a current exhaust brake torque and a maximum exhaust brake torque. A display is configured to display at least one of the current exhaust brake torque, the maximum exhaust brake torque and a percentage corresponding to the current exhaust brake torque divided by the maximum exhaust brake torque. An engine speed sensor determines an engine speed of an engine. A pressure sensor is configured to sense turbine inlet pressure. The controller is configured to calculate the current exhaust brake torque and the maximum exhaust brake torque in response to the engine speed and the turbine inlet pressure.

    摘要： A system according to the principles of the present disclosure includes an exhaust braking enabling module, a driver torque module, and an engine actuator control module. The exhaust braking enabling module selectively enables exhaust braking based on driver input and independent of an accelerator pedal position. The driver torque module selectively determines a driver torque request based on a powertrain braking torque capacity when exhaust braking is enabled. The engine actuator control module controls fuel delivery to cylinders of an engine and a vane position of a turbocharger based on the driver torque request.

    摘要： A hybrid driving apparatus includes a diesel engine outfitted with an exhaust brake, and a clutch between the diesel engine and a hybrid motor. The exhaust brake is shiftable between an operational state and a non-operational state, and a switch is operable to change the exhaust brake from the non-operational state to the operational state. The switch is configured to automatically change the exhaust brake which is in the operational state while the vehicle is turned on to the non-operational state when the vehicle is turned off. The clutch is automatically changed from an engaged condition, in which the diesel engine and the hybrid motor are connected, to the disengaged condition, in which the diesel engine and the hybrid motor are disconnected, when the vehicle decelerates while the exhaust brake is in the non-operational state.

    摘要： 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.
