A construction machine traveling control system is provided. The construction machine traveling control system includes first and second electric traveling pedals for outputting manipulation values including electric signals in response to the driver's manipulation and thereby operating first and second traveling motors connected thereto, respectively; a traveling pattern input means installed in the driving room so as to enable the driver to input a construction machine traveling pattern; a controller electrically connected to the first and second electric traveling pedals and to the traveling pattern input means; and a hydraulic circuit electrically connected to the controller so as to control the flow rate of operation oil supplied to the first and second traveling motors, as well as the flow of the operation oil, according to the command values delivered from the controller.

An energy storage tank defining a tank volume for heat transfer fluid and comprising a partition dividing the tank volume into a first volume and a second volume, wherein the partition is movable to/from any position between a minimum energy storage position corresponding to a minimum second volume, and a maximum energy storage position corresponding to a maximum second volume, the energy storage tank further comprising a biasing device being arranged such that movement of the partition away from the minimum energy storage position corresponds to storing energy in the biasing device, and movement towards the minimum energy storage position corresponds to releasing energy from the biasing device.

An automobile or other wheeled vehicle includes various hydraulic components, including a hydraulic gearbox, transmission, clutch, and brake energy recovery system. Such hydraulic components supplement or replace traditional mechanical components of the automobile or other wheeled vehicle to improve the overall operational efficiency thereof.

A dual-motor power system or a dual-motor hybrid power system for a vehicle comprises a first motor, a second motor, an intermediate shaft, a first gear set disposed between a first driving shaft, and an intermediate shaft. The first driving shaft couples with the intermediate shaft via the first gear set, a second gear set disposed between the second driving shaft and the intermediate shaft, and a single synchronizer disposed around the second driving shaft. The synchronizer can be switched between a neutral position, a first-speed-ratio position, and a second-speed-ratio position. In the neutral position, the second driving shaft is decoupled from the first and second gear sets. In the first-speed-ratio position, the synchronizer couples the second driving shaft with the intermediate shaft via the first gear set. In the second-speed-ratio position, the synchronizer couples the second driving shaft with the intermediate shaft via the second gear set.

Embodiments of an intelligent power allocation system include a ground traction undercarriage controllable to propel a hybrid combine over terrain, a separator device configured to separate grain from other crop material ingested by the hybrid combine, a mechanical powertrain including an internal combustion engine, and an electric drive subsystem containing a rechargeable battery pack and a motor/generator (M/G). A controller architecture is configured to monitor a current separator load placed on the hybrid combine when driving movement of the separator device during active harvesting. The controller architecture further selectively places the intelligent power allocation system in a separator power splitting mode in which the M/G and the internal combustion engine concurrently drive movement of the separator device based, at least in part, on whether the current separator load exceeds an upper load threshold.

A control device supplies electric power to a shift-by-wire system to a sub power supply until starting of an engine by automatic start control is completed after the engine has been stopped by automatic stop control. The control device performs a stopped range switching process in response to outputting of a signal for requiring switching of a shift range from a selection device when electric power is supplied from the sub power supply to the shift-by-wire system. In the stopped range switching process, the shift range is switched to a selected shift range when a voltage of the sub power supply is equal to or greater than a threshold value. On the other hand, the shift range is switched to a neutral range when the voltage of the sub power supply is less than the threshold value.

A fuel cell vehicle includes a bypass valve positioned downstream of a compressor and upstream of a fuel cell stack to selectively direct airflow from the compressor to an exhaust bypassing the fuel cell in an attempt to clear a partially or fully obstructed exhaust pipe. The bypass valve may be opened by a controller when an exhaust throttle valve is at or near a wide-open throttle position. The controller may also increase compressor flow and adjust airflow to the fuel cell stack until compressor pressure, speed, or temperature exceed corresponding limits.

A seatbelt of a work vehicle includes: a first stay provided in correspondence with a first fixing portion of a vehicle body on either one of right/left sides of a seat; a belt reeling portion that reels and stores a belt main body and is attached to the first fixing portion via the first stay; a second stay provided in correspondence with a second fixing portion on the other one of the right/left sides of the seat; and a buckle portion that fixes an insertion fixture extending from the belt reeling portion and is attached to the second fixing portion via the second stay. A first cover member is mounted to the first stay and covers an outward exposed portion of the first stay. A second cover member is mounted to the second stay and covers an outward exposed portion of the second stay.
