A vehicle information providing system is realized, which is capable of providing appropriate vehicle information depending on a used driving energy source. The kind of fuel used when refueling a vehicle is identified based on image information from a camera provided in a service station, and/or payment information for the refueling. The magnitude of the environmental burden caused by the identified fuel is specified so as to change, according thereto, a background color of an instrument panel of the vehicle. Also, a turn-on/turn-off state and a lighting color of an eco-lamp provided on a rear surface of the vehicle is changed. Thus, the appropriate vehicle information is provided in consideration of differences in the environmental burden depending on the used fuel even when the vehicle model is the same.

Vehicle information providing system

A gear change control device according to an embodiment includes a detection unit configured to detect the gear stage of a transmission and measure the input rotation rate of the transmission and the rotation rate of an engine and a controller configured to decrease the torque of a clutch to a second reference value from a first reference value when a first time elapses from a time point at which the rotation rate of the engine and the input rotation rate of the transmission become different from each other due to a gear change from a certain gear stage to a gear stage one or a plurality of stages higher than the certain gear stage that is performed by the transmission.

Gear change control device

A first dog ring and a second dog ring are biased toward each other by means of springs. When the first dog ring and the second dog ring are moved away from each other, bias force produced by the springs is applied to the second dog ring in a direction to draw the second dog ring toward the first dog ring. Accordingly, when the first dog ring is moved away from the second dog ring during shifting, the second dog ring is drawn toward the first dog ring under the bias force, and third engaging teeth of the second dog ring and meshing teeth of a first-speed gear are promptly disengaged from each other.

Transmission for vehicle

This apparatus is provided with a clutch mechanism. The clutch mechanismis interposed between an engineand a transmission, and is coupled to a clutch pedal. An operating mode of the clutch mechanismchanges in conjunction with a change of an operating position of the clutch pedal. In the case that an execution condition is met, the apparatus lowers a maximum operating speed of the clutch mechanismin comparison with a state in which an execution condition is not met. The execution condition includes the following execution start condition that 'the operating position of the clutch pedalis a position setting the clutch mechanismto a disengaged state, and a changing speed of the operating position of the clutch pedalin an engaging direction at a time of setting the clutch mechanismto an engaged state from the disengaged state is equal to or higher than a predetermined starting speed'.
