An oil pump includes a first spill passage formed on a side surface () of a pump chamber () to communicate a hydraulic pressure chamber () with a first high pressure discharge passage () when the entire hydraulic pressure chamber () is positioned between the first high pressure discharge passage () and a first low pressure discharge passage (). Therefore, when the hydraulic pressure chamber () passes between the first high pressure discharge passage () and the first low pressure discharge passage (), the hydraulic pressure inside the predetermined hydraulic pressure chamber () escapes to the first high pressure discharge passage () through a first spill passage (), so a hydraulic pressure value inside the hydraulic pressure chamber () is maintained at the pressure value inside the first high pressure discharge passage (). As a result, fluid is inhibited from flowing into the hydraulic pressure chamber () from the first high pressure discharge passage () through a space between inner peripheral teeth () and outer peripheral teeth ().

Vehicular internal gear type oil pump

A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced.

Vehicular power transmitting system

An apparatus includes a laser projector and a laser beam ECU that is connected to a vehicle communication apparatus for communicating with an information center that provides a guidance service by an operator. According to an operation guidance by the operator, information indicating a switch to be operated is sent from the information center to the laser beam ECU through the vehicle communication apparatus. Then, the laser beam ECU identifies the switch to be operated based on the information and controls the laser projector to direct a laser beam to the switch to be operated.

Information is displayed by irradiating a visible light on a specific position based on at least one of vehicle state information, vehicle surrounding information, and vehicle interior information. For example, the visible light is irradiated on a target switch based on signals indicating an on/off state of a headlamp operation switch and an on/off state of a key switch. A usercan easily confirm the target switch and unerringly operate the target switch. A visible light irradiatoris arranged in a vehicle compartment and irradiates the visible light to display information in the vehicle compartment. The information can be provided for the userin a novel manner.

Interior information display apparatus and light irradiation apparatus used for the same

A projector projects a visible laser beam onto a region of a vehicle compartment. A control unit controls a direction of projecting the visible laser beam to provide information to at least one occupant in the compartment. The control unit expands the region of an object to which the visible laser beam is projected when the seatbelt has been fastened.

A visible laser beam projection system for a vehicle projects visible laser beam onto an instrument panel in a vehicle compartment. The instrument panel is provided with highly reflecting portions, which are scattered on the upper surface of the instrument panel. The highly reflecting portions having a diffuse reflectivity for the wavelength of a visible laser beam higher than that of other portions of the instrument panel. The visible laser beam is projected to the highly reflecting portions.

A visual ability improvement device installed in a vehicle includes a noise generator, a surrounding situation detector, a driver status detector, a vehicle status detector, an operation switch, and a noise output device. A controller of the noise generator determines an optimum strength based on the surrounding situation from the surrounding situation detector, the driver's status from the driver status detector, the vehicle's status from the vehicle status detector, and the correspondence of the optimum representative noise to the above situation and statuses from the correspondence memory. Then the controller generates a noise with the determined the optimum representative noise strength, and outputs to the noise output device such as passenger compartment light a control signal which depends on the generated noise.

An electronic device mounting structure includes a thermally conductive base, a busbar located on the base, an electronic device mounted on the busbar, a thermally conductive wall standing on the base and having first and second portions located opposite each other across the electronic device, and a plate spring supported by the first and second portions of the wall. The plate spring presses the electronic device against the base so that thermal resistance between the electronic device and the base is reduced. The plate spring has a thermal conductivity so that heat in the electronic device is transferred to the wall through the plate spring.

A visible laser beam projection system determines a target point of position to which a visible laser beam is to be projected, a start point and a trajectory from the start point and the target point based on data of conditions inside and outside of a vehicle. The system starts projecting the visible laser beam from the start point, moves the visible laser beam while it is being projected along the trajectory and stops the projection of the visible laser beam. The start point, target point and the trajectory may be changed depending on contents to be indicated.

A visual ability improvement supporting device includes a noise outputting device and a noise generating device. The noise generating device generates noise with intensity which is optimum to a threshold intensity of visibility. The optimum intensity is optimum to induce stochastic resonance (SR). The noise outputting device includes a room lighting device, which illuminates a surrounding area when a lighting switch is turned on, and outputs the visual noise according to the generated noise even when the lighting switch is turned off not to illuminate the surrounding area.

To simplify the assembling of a vehicular cockpit module assembly, an instrument panel and its peripheral devices are divided into a plurality of sub module assemblies each of which having a corresponding main device. Each of the assemblies is assembled as a unit, and then the assemblies are mutually assembled. The assembling of each sub module assembly is completed to form a unit in advance.

Vehicular cockpit module assembly and assembling method

In an assembling structure of a vehicle center cluster, plural electrical devices are detachably assembled to a holding member to be removed from an inside of a passenger compartment while the holding member is fixed to a dashboard. Therefore, for example, when a CD deck is removed from the center cluster into the passenger compartment among the electrical devices, only the CD deck can be removed from the holding member into the passenger compartment without removing the other electrical devices, in a fixed state of the holding member to the dashboard. Accordingly, removing operation of the electrical devices can be made simple.
