Abstract: A route searching device according to an embodiment of the invention includes an estimated fuel consumption amount computing unit that computes an estimated fuel consumption amount of each interval constituting plural routes from a departure point to a destination and an optimum route selecting unit that selects a route in which a total of the estimated fuel consumption amount from the departure point to the destination is minimized. The estimated fuel consumption amount may be obtained by adding a cruise fuel consumption amount, a gradient fuel consumption amount, and a vehicle-speed fluctuation fuel consumption amount. In a further aspect, an average fuel consumption value for each speed range of an interval may be determined based on limited fuel consumption data, and fuel consumption values may be updated using measured probe data.

Abstract: An energy map for a motor vehicle and an energy mapping system for making the energy map are disclosed. The energy map includes energy information related to energy consumption and energy recharging of various power sources along various roadway segments. The energy mapping system may include a navigation system for a motor vehicle comprising a GPS receiver, various energy level sensors, and an electronic control unit. A probe vehicle may be used to measure energy consumption and energy recharging for various power sources. The energy mapping system may also include a service provider. The navigation system may measure energy levels for the various power sources along various roadway segments and transmit the measurements to the service provider. The service provider may then associate differences in the measured energy levels for each of the various power sources with the various roadway segments.

Abstract: A user selects route preferences related to weighing or considering different factors when determining a requested candidate route to a destination and chooses a candidate route ranking. A motor vehicle detects a condition associated with a vehicle state. The motor vehicle displays the candidate route based on the detected vehicle condition in a preselected order determined by the route ranking.

Abstract: Minimum energy routes for a motor vehicle are determined. The minimum energy routes can be calculated using an energy map. Energy management information is determined and provided along the minimum energy route.

Abstract: A navigation system displays multiple alternative routes, some of which use a carpool lane. The calculation of multiple alternative routes allows the user the choice to select a route with a desired number of passengers after the routes and comparative times to travel those routes has been calculated.

Abstract: A comparator is supplied with a hold visit code and a visit guidance message, which are received by a receiver from a broadcasting device via radio waves. Alternatively, the comparator is supplied with a hold visit code and a visit guidance message, which are received by a communicating unit from a server through a public circuit network, a wireless link, a cellular phone unit, and another wireless link. The comparator then compares the supplied HVC with an HVC that is stored in a message table in a storage unit. If the HVCs compared by the comparator agree with each other, then an information output unit resets the HVC stored in the message table, and outputs the visit guidance message to an output unit.

Abstract: A studless tire comprises tread blocks having a narrow-width center portion, a heel-side increasing-width portion and a toe-side increasing-width portion, wherein the axial width of the block becomes minimum in the narrow-width portion and increases toward the heel edge and toe edge in the heel-side and toe-side increasing-width portions, and the minimum width in the narrow-width portion being in the range of from 0.5 to 0.9 times the average of the maximum width in the heel-side increasing-width portion and the maximum width in the toe-side increasing-width portion, whereby the stress produced in the block rubber when a braking force or driving force acts thereon increases the apparent block rigidity to decrease the block edge lifting and thereby uneven wear can be decreased.

Abstract: A studless tire with a tread pattern comprising blocks that are defined by longitudinal and transverse grooves and having at least one row of blocks that extends in the peripheral direction of the tire. The peripheral rows of blocks are such that at least one sub-block is provided within one pitch of the tread pattern outside an adjacent block in the tire's rotating axle. And the sub-block is separated from the block by a sub-groove less deep than the longitudinal and transverse grooves and has the longer side in the peripheral direction and the shorter side in the direction of the rotating axle.
