[PROBLEMS] To provide a coaxial connector assembly maintaining a characteristic impedance and allowing floating. [SOLUTION] First to third coaxial connectorstoare provided. A second center conductorof the second coaxial connectorhas a second shaft portionA held by a second dielectric body, a right columnar one-end-side contact portionB to be fitted in a first receiving portionB of the first coaxial connector, and the other-end-side contact portionC to be fitted in a third center contact portionB of the third coaxial connector. The one-end-side contact portionB is larger than the outer diameter of the second shaft portionA. A distance in a radial direction between the one-end-side contact portionB and a first fitting portionB of a first external conductoris impedance-matched to an impedance between a first center conductorand the periphery thereof and an impedance between the second shaft portionA of the second center conductorand the periphery thereof. The first and second coaxial connectorsand the second and third coaxial connectorsform floating structures.

Coaxial connector assembly

A coaxial connector assembly including a plug connector and a receptacle connector each holding a coaxial terminal including a center and an external terminal surrounding the center terminal, wherein housings of the plug connector and the receptacle connector have an engageable/disengageable lock mechanism, in an engagement state, a range of relative movement between the coaxial terminals in an axial direction is smaller than a shorter one of a center terminal effective fitting length, which is a distance from a start position to an end position of contact between the center terminals, or an external terminal effective fitting length, which is a distance from a start position to an end position of contact between the external terminals, and an impedance in the axial direction range of the minimum effective fitting length is matched to a specific impedance.

Disclosed is an information terminal for electric-powered vehicles or a cruise controller therefor to provide a driver with a traveling method that can shorten a total required time to a destination including a charging time. An information terminal for electric-powered vehicle configured to calculate a required time for the vehicle to travel a route from a current position to a destination in accordance with map information, includes: route setting means that searches for a route to the destination; recharging place setting means that sets a charging place on a way of the route to the destination set by the route setting means; and charging facility information acquisition means that acquires information on the charging place set by the recharging place setting means. A recommended vehicle speed or a vehicle speed range including the recommended vehicle speed at a section to the charging place is calculated.

Information terminal and cruise controller for electric-powered vehicle

A running control device for an electric vehicle includes: a first calculation unit that calculates a predetermined reference torque required for braking/driving the motor that provides a beneficial effect with regard to power consumption of the electric vehicle; a second calculation unit that calculates interval allocation between a first interval in which the electric vehicle is propelled by braking/driving the motor at the predetermined reference torque and a second interval in which the electric vehicle is coasted without the motor being braked or driven; a third calculation unit that calculates a control requested torque for braking/driving the motor intermittently, so as alternatingly to repeat running of the electric vehicle in the first intervals and coasting of the electric vehicle in the second intervals; and a running control unit that performs running control of the electric vehicle by braking/driving the motor intermittently according to the control requested torque.

Running control device for electric vehicle

A connector to be connected to a mating connector, includes a connector main body including a cylindrical member, a supporting member disposed in the cylindrical member, a terminal supported on the supporting member, and a fitting portion having an engaging portion; a movable sleeve including a diameter control portion; an elastic deformation member disposed to be elastically deformable in a radial direction thereof; an accommodating portion disposed between the connector main body and the movable sleeve for accommodating the elastic deformation member; and a transmission unit for transmitting a force in the axial direction from the movable sleeve to the elastic deformation member when the movable sleeve moves, and for transmitting a force in the radial direction from the elastic deformation member to the movable sleeve when the elastic deformation member returns to an original shape.

A driving control device for a vehicle in which one of a front-wheel side and a rear-wheel side is driven by an engine and an other of them is driven by a motor, reduces a driving force by the motor to recover a grip and estimates a road friction coefficient. The driving control device further transmits an engine driving force to drive wheels, and temporary increases the motor driving force in accordance with the engine driving force and the motor drive wheel grip limit line according to an estimated road friction coefficient.
