A driving control method of a hybrid vehicle is provided. The method includes when a specific zone related to discharge of exhaust gas is detected ahead on a path, determining whether a current state of charge (SoC) of a battery is greater than a first value. When the current SoC is greater than the first value, driving in a first mode for charging the battery in power of an engine in a first section disposed before entrance into the specific zone. Upon entering a second section corresponding to the specific zone, a current mode into a second mode for driving using power of a motor only is converted, battery consumption is reduced using at least one step along with a change in the current SoC in the second section.

A method of managing charging of a traction battery and corresponding devices, the traction battery including a thermal regulating system, the thermal regulating system including a compressor, the method including transmitting information between a control device for the compressor and a device for managing the charging of the traction battery, before activating the compressor or before activating a device for charging the traction battery.

A vehicle includes an internal combustion engine, an electric machine, and a controller. The electric machine is rotatably coupled to the engine and is configured to deliver electrical power to electrical accessories. The controller is programmed to, in response to a control signal loss between the electric machine and the controller, limit torque output of electric machine to less than a torque threshold that corresponds to the power threshold. The controller is further programmed to, in response an accessory power demand being greater than the power threshold, control the engine to power the electric machine to increase the torque output of electric machine to greater than the torque threshold to meet the accessory power demand.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a pump system, and a driveline. The driveline includes a front axle coupled to the chassis, a rear axle coupled to the chassis, an energy storage system, an engine coupled to the chassis, and an electromechanical device coupled to the chassis, the engine, and at least one of the front axle or the rear axle. The driveline is a dual drive driveline such that, during any and all modes of operation of the driveline, the electromechanical device is incapable of or prevented from charging the energy storage system at any time when driven by the engine.

Systems and methods for improving shifting of a manual transmission coupled to an engine are presented. In one example, a load provided to the engine is increased in response to a transmission gear upshift so that engine speed may be quickly decreased to synchronize with transmission input speed, thereby allowing quicker manual transmission gear shifts.

A vehicle accessory power management assembly includes a vehicle speed sensor, an accelerator sensor, an accessory device, a power transmitting device and a controller. The power transmitting device receives rotational power from a power device and transmits it to the accessory device. The power transmitting device is switchable between a first operating state and a second operating state. In the first operating state the accessory device is operated at a first power consumption level and in the second operating state the accessory device is operated at a second power consumption level lower than the first power consumption level. The controller is configured to switch the switching part from the first operating state to the second operating state in response to determining that a current level of acceleration requested of the power device is of greater importance than operating the accessory device at the first operating state.

A military vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a driveline. The driveline includes an engine, an energy storage system, a front end accessory drive positioned in front of and coupled to the engine, a transmission coupled to at least one of the front axle or the rear axle, a second motor coupled to the transmission and electrically coupled to the energy storage system, and a clutch positioned between the engine and the second motor. The front end accessory drive includes an air compressor and a first motor. The first motor is electrically coupled to the energy storage system. The clutch is spring-biased into engagement with the engine and pneumatically disengaged by an air supply selectively provided thereto based on operation of the air compressor. The driveline is operable in an engine-only mode and an electric-only mode.

A method for operating a drivetrain of a motor vehicle, includes, when the motor vehicle is at a standstill and upon demand for a drive torque of the motor vehicle, increasing power (25p) supplied to a separate electric pump drive (25) such that a pressure chamber whose pressurization effects a complete closure or lock-up of a launch element (3) is fast charged with hydraulic pressure from a pump (24). The method also includes performing a launch process of the motor vehicle with the drive source (1) and with a closed or locked-up launch element (3) and reducing the power (25p) supplied to the separate electric pump drive (25) after fast charging the pressure chamber. A related drive train module is also provided.

A vehicle is provided. The vehicle includes an engine, an electric machine, an electric heater, and a controller. The electric machine is configured to recharge a battery through regenerative braking. The electric heater is configured to heat an engine coolant. The controller is programmed to redirect regenerative braking power to the electric heater in response to the engine coolant temperature being below a threshold.

Provided is hybrid construction machine that can charge/discharge an electrical storage device appropriately and can suppress stop of an engine accompanying sharp increase of a load. The present invention includes a hybrid controller 22 that controls power of a hydraulic pump 17 and electric power of an inverter 15 in response to storage battery characteristics of the electrical storage device 16, and an output command unit 22F of the hybrid controller 22 is configured to control at least either one of the power of the hydraulic pump 17 and the electric power of the inverter 15 on the basis of at least either one of electric current or voltage of the storage battery characteristics and at least either one of temperature or a state of charge of the storage battery characteristics.
