Energy regeneration device and work machine provided with energy regeneration device
An energy regeneration device which can regenerate energy of a working fluid discharged from an actuator while controlling a flow rate of the working fluid, and a work machine including the device. The regeneration device includes a boom cylinder, an inertial fluid container, an oil tank, an accumulator, a low-pressure-side opening/closing device, and a high-pressure-side opening/closing device. A calculation unit calculates an opening area of each of the low-pressure-side opening/closing device and the high-pressure-side opening/closing device in accordance with a desired flow rate of a hydraulic fluid discharged from the boom cylinder. A regeneration control unit adjusts an opening area of each of the low-pressure-side opening/closing device and the high-pressure-side opening/closing device, and selects alternately the low-pressure-side opening/closing device and the high-pressure-side opening/closing device as a destination with which the inertial fluid container communicates, to supply a discharged hydraulic fluid to an accumulator.
Chassis power management
A vehicle control system includes a brake module operably coupled to a braking system to provide a braking torque request, a steering module operably coupled to a steering system to provide a steering input request, a power supply, and a power management module. The power supply is operably coupled to the brake module and the steering module to provide power to the brake module and the steering module. The power supply has a power budget indicating a maximum power providable to the brake module and the steering module. The power management module is operably coupled to sensors to receive a power draw indication from one of the brake module or the steering module and control power draw of the other of the steering module or the brake module to maintain a combined power draw of the brake module and the steering module below the power budget.
