A lubrication loop includes a main flow path connected to a lubrication flow path, a control valve connected to the main flow path, a return flow path connected to the control valve and configured to return the fluid to the fluid pump, and a sub-flow path branching off from the main flow path. The control valve includes a discharge port at a distance from a supply port of a valve housing chamber and connected to the return flow path, an open port formed at one end of the valve housing chamber to discharge the fluid, an annular recessed portion formed on an outer circumferential surface of the spool has a width extending from the supply port to the discharge port, and a sub port annularly formed between the discharge port and the open port on an inner circumferential surface of the valve housing chamber and connected to the sub-flow path.

Fluid pressure loop

A vehicle includes a motor configured to drive a vehicle wheel, a battery configured to supply electric power to the motor, and a radiator configured to exchange heat between a coolant for cooling the motor and outside air. The radiator is disposed below a floor surface of the vehicle and in a gap between the motor and the battery in a front-rear direction of the vehicle.

Vehicle having cooling arrangement disposed below floor surface

An opening end of an inboard section includes: an end surface composed of a plane positioned farthest from the center of a differential device in the axial direction and perpendicular to the axial direction; a ledge positioned adjacent to the end surface in the circumferential direction of the opening end and closer to the center than the end surface in the axial direction; and a tapered section in a slope shape formed continuing to the inner diameter side of the ledge at the opening end, slanting toward the inner diameter side of the opening end and approaching the center. Lubricating oil supplied to the opening end of the inboard section flows to the tapered section via the ledge and flows from the tapered section into a spiral groove formed on an inner periphery of the inboard section.

Lubrication structure for differential device

A vehicle automatic transmission includes a plurality of gears provided on an input shaft, a countershaft, and an output shaft and are meshed with one another. A plurality of hydraulic clutches are each configured to couple any of the gears to the input shaft, the countershaft, or the output shaft to establish a predetermined shift stage. An engagement unit is configured to couple a reverse gear to the input shaft or the countershaft to establish a reverse shift stage. A shift-position detection unit is configured to detect a shift position. A vehicle-speed detection unit is configured to detect a vehicle speed. A control unit is configured to detect, based on an output of the shift-position detection unit, a first time and a second time. The control unit is configured to delay a timing when the engagement unit operates after the shift position changes to an R-position.

Vehicle automatic transmission

In a location confirmation system, one navigation terminal connects a line to an information center to transmit timing information, and the information center identifies other navigation terminals for exchanging information indicating current locations to transmit the timing information to them. Thereafter, other navigation terminals having received the timing information and one navigation terminal transmit and receive the information indicating each current location at almost equal timing in accordance with the timing information.

Location confirmation system and information transmitting method for use in the system

A communication navigation system is provided with: a communication navigation terminal () and a communication center apparatus () with a communication network () for connecting them. The communication navigation terminal is provided with a traveling locus recording device () for preferentially holding a traveling locus recorded when a movable body is driving out of a service area of the communication navigation system; and a processing device () for performing a route search and the like on the basis of this preferentially held traveling locus.

Communication navigation system and method, program storage device and computer data signal embodied in carrier wave

A communication type navigation apparatus can communicate with a server device via a communication path. The navigation apparatus requests route search, and the server device executes route search to produce route information of a searched route. Then, the meshes necessary to travel along the searched route are determined, and the navigation apparatus obtains necessary mesh data from the server device. The navigation apparatus may request newer mesh data to the server device based on the updating information of the mesh data. By appropriately determining the mesh data to be and not to be downloaded from the server device, the communication cost necessary for obtaining the mesh data can be saved.

Communication-type navigation apparatus and server device

A communication state monitoring section of a terminal unit installed in a vehicle checks whether communication is possible between the terminal unit and a server system . If the section in question finds communication is not possible, information regarding the current position of the vehicle and its target point and search condition acquired by the terminal unit is stored in an internal memory, and communication is suspended. Communication state is checked at predetermined intervals. As soon as it is confirmed that communication is possible, the server system determines a path to be taken by the mobile body and a signal notifying the path is transmitted to the terminal unit , which then guides the navigation of the vehicle. According to this system, it is not necessary to restart operations even if communication is interrupted and recovers after a certain interval, which will improve the utility of the system.
