A vehicle drive system including: a front drive unit in a front part of a vehicle, which has an engine and a torque converter integrally assembled to one another; a rear drive unit in a rear part of the vehicle, which has a transmission and a differential integrally assembled to one another; and a drive shaft connecting the torque converter of the front drive unit and the transmission of the rear drive unit. The drive shaft is configured to be elastically twistable for damping vibration transmission between the front and rear drive units.

A cutting tip having a three-layer laminated structure is provided. The tip is made from a disc-shaped three-layer laminate wherein a second layer consisting of a hard sintered compact of CBN or diamond is sandwiched by a first layer and a third layer consisting of a tool material such as cemented carbide. Prismatic blanks of rectangular cross-section are cut out by cutting the three-layer laminate in strips. Semi-completed tips of a desired shape are obtained by cutting up the prismatic blanks. Desired cutting edges are formed on the semi-completed tips to produce completed tips. Because prismatic blanks are obtained from a three-layer laminate and semi-completed tips are cut out from the prismatic blanks like this, the semi-completed tips can be obtained in large numbers, yield is high, and the manufacturing cost of the tip can be reduced.

摘要:
A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which a vehicle speed sensor which output an analog quantity corresponding to a current vehicle speed is provided, a vehicle speed determining circuit which derives the current vehicle speed on the basis of the analog quantity derived from the vehicle speed sensor and determines whether the derived current vehicle speed is below a predetermined speed above which the cruise speed control run is appropriate is furthermore provided independently of a control unit of the system. When the vehicle speed determining circuit outputs a determination signal indicating that the current vehicle speed is below the predetermined speed and the control unit outputs a predetermined control command signal, a power supply line connected to a throttle valve actuator is, at first, interrupted. Then, the power supply to the control unit is interrupted.

A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which whether a microcomputer of a control unit is enabled to perform a cruise speed control is determined on the basis of a plurality of determining factors and a power supply of a throttle actuator for actuating an engine throttle valve so as to adjust an opening angle of the throttle valve is enabled only when all of the determining factors satisfy a condition of enabling the cruise speed control via the actuator and is disabled when at least one of the determining factors does not satisfy the condition.

A flexible printed circuit substrate is bent in a flattened rectangular C-shape and electronic parts generating heat are mounted on the inner surface of a central portion of the C-shaped substrate. Then a radiating heat-sink plate is adhered on the outer surface of that central portion. Temperature-sensitive electronic parts are mounted on one end portion of the C-shaped substrate and parts consisting of a power supply circuit are mounted on the other end portion. Then the entire assembly is accommodated in a housing having a connector.

A battery unit comprises plural side connection portions which are provided at its both-side end portions in a vehicle width direction and connected to said vehicle-body member, and these connection portions are connected to a high rigidity portion of a vehicle-body member, concretely, to the vehicle-body member at a specified position where floor cross members integrally connected to a vehicle floor panel are located, to the vehicle-body member at a specified position where a torque box is located, or to the vehicle-body member at a specified position where a kick-up portion of the vehicle floor panel is located. Accordingly, the torsional rigidity of the vehicle body can be increased by utilizing the battery unit mounted below the vehicle body floor (vehicle floor panel).

A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which in addition to a control unit and a throttle actuator through which an opening angle of an engine throttle valve is adjusted so that the vehicle speed detected by a vehicle speed sensor coincides with a target cruise speed set by a vehicle driver through a set switch, a vehicle speed determining circuit is provided for determining whether the vehicle speed detected by the vehicle speed sensor exceeds a lowest speed limit above which the cruse control by the control unit and throttle actuator becomes effective. When the vehicle speed is below the lowest speed limit, the power supply to the throttle actuator is interrupted so that the cruise control by means of the throttle actuator is cancelled.
摘要:
A cruise control system for an automotive vehicle with a manual or automatic transmission, includes an inhibition circuit. The inhibiting circuit blocks communication between a power supply and an actuator and/or a controller when the manual transmission is set in a predetermined gear or when the automatic transmission is set in a driving range other than the drive range, so as to inhibit the controller from operating in the cruise control mode. When the vehicle is provided with an automatic transmission which is selectively set in first, second, third or fourth gear while the shift lever is set in the drive range position, the cruise control system includes a first inhibiting circuit which blocks the communication when the shift lever is set in a position other than the drive range position, and a second inhibiting circuit which blocks the communication when the automatic transmission is set in either the first or second range while the shift lever is set in the drive range position.
