A hydraulic hammering device enables an auto-stroke mode and an idle strike prevention mode to coexist with a simple circuit configuration. The device includes a first control valve to control advancing and retracting movements of a piston, an auto-stroke mode and an idle strike prevention mode, and a second control valve to select either of the auto-stroke mode or the idle strike prevention mode. To the second control valve, a shared spool is slidably fitted and a mode selection means is disposed. When the mode selection means allows supply of pressurized oil to an auto-stroke setting portion of the shared spool and prohibits discharge of pressurized oil from an idle strike prevention setting portion, the auto-stroke mode is selected. When prohibiting supply of pressurized oil to the auto-stroke setting portion and allowing discharge of pressurized oil from the idle strike prevention setting portion, the idle strike prevention mode is selected.

A parking management system is provided that addresses the problem of parking difficulties in auto-valet situations where vehicle size is not taken into account. It includes a target parking position determination unit, a route generation unit, and a vehicle control unit. The determination unit considers parking block sizes, empty vehicle space position, and the own vehicle's size to find a suitable parking spot. The route generation unit creates a guidance route from the entrance to the target parking position. The vehicle control unit autonomously drives the own vehicle along the generated route. The system generates potential routes based on entrance or exit positions and determines a turning point on the route. If the own vehicle can safely navigate the turning point considering parked vehicle sizes and minimum turning radius, that route is selected as the guidance route.

A host lane environment recognition unit acquires an operation of a target vehicle traveling in a host lane and a road environment. An adjacent lane environment recognition unit acquires operation of vehicles traveling in an adjacent lane and a road environment. A lane changeable space determination unit determines whether the host vehicle can change lanes using road environment information of the adjacent lane. A lane change control unit determines whether the target vehicle traveling in the host lane is allowed to change lanes, based on the operation of the target vehicle and the adjacent vehicle traveling in their lanes. The lane change control unit causes the host vehicle to change lanes based on determining whether the host vehicle can change lanes in the adjacent lane by the lane changeable space determination unit and whether or not the target vehicle is allowed to change lanes.

Vehicle control device and control method

A hydraulic hammering device is capable of sufficiently transmitting blow energy to bedrock while further strengthening cushioning action and suppressing damage to equipment. The device includes a pushing piston disposed behind a transmission member and having a smaller propulsive force than that of a main body, a damping piston positioned behind the pushing piston to slide reciprocally forwards and backwards and having a greater propulsive force than that of the main body, a direction-restrictor in a high-pressure circuit between pushing and damping chambers, to which hydraulic fluid is supplied for providing the pistons with propulsive forces, and a fluid supply source. The direction-restrictor restricts an outflow from the chambers side to the fluid supply source side while allowing fluid inflow from the fluid supply source side to the chambers and the pushing chamber sides. A throttle in a drain circuit discharges leaked fluid from a sliding contact location to a tank.

Provided is a hydraulic hammering device having improved hammering efficiency and of low cost. A piston has a valve switching groove between large-diameter sections thereof. A cylinder has three control ports at positions corresponding to the valve switching groove. A switching valve mechanism has a valve presser for always pressing a valve in one direction and also has a valve controller for moving, when supplying pressurized oil, the valve in the opposite direction against the pressing force of the valve presser. A valve control port communicates with the valve controller so as to supply the pressurized oil to the valve controller and is separated from a piston front chamber and a piston rear chamber. Only either a piston retraction control port or a piston advance control port communicates with the valve control port depending on advance or retraction of the valve switching groove.
