A control apparatus for a vehicle drive-force transmitting apparatus which includes a gear mechanism and a continuously-variable transmission mechanism and which establishes selectively a first state in which a drive force is transmitted by the gear mechanism and a second state in which the drive force is transmitted by the continuously-variable transmission mechanism. The control apparatus sets a shift-up-action permitted gear ratio of the continuously-variable transmission mechanism, which makes a state-switch-requiring shift-up action is permitted to be executed. When a running speed of the vehicle is not higher than a given value, a predetermined high gear ratio value is set as the shift-up-action permitted gear ratio. When the running speed is higher than the given value, a predetermined gear ratio range ranging from the predetermined high gear ratio value to a predetermined low gear ratio value is set as the shift-up-action permitted gear ratio.

A control apparatus for a vehicle drive-force transmitting apparatus which establishes selectively a first state in which a drive force is transmitted by a gear mechanism and a second state in which the drive force is transmitted by a continuously-variable transmission mechanism. The control apparatus executes a shift-up action requiring the first state to be switched to the second state, in (a) a case in which a state of the drive-force transmitting apparatus satisfies a first condition that a gear ratio of the continuously-variable transmission mechanism is not lower than a first gear ratio value and in (b) a case in which the state of the drive-force transmitting apparatus satisfies a second condition that a lap-down control is executed with the gear ratio of the continuously-variable transmission mechanism being not lower than a second gear ratio value that is lower than the first gear ratio value.

In a constant-velocity joint, a center locus of a ball rolling on a first outer large-diameter portion has an arc shape having an arc center, and a center locus of the ball rolling on a second outer large-diameter portion has an arc shape having an arc center. Center loci of the ball rolling on an outer extension portion are positioned, throughout their lengths, in a region inducing a tangent line to an opening-side end portion of the center locus of the ball rolling on the second outer large-diameter portion, the region being positioned outward of the tangent line in a radial direction of the outer joint member. An opening-side end portion of the center locus of the ball rolling on the outer extension portion is positioned outward of the tangent line in the radial direction of the outer joint member.

While a microcomputer is executing a self-diagnosis (A), second diagnosis pulse output means of a B-system microcomputer is not used utterly. Further, during this time, the B-system microcomputerB does not execute a processing relating to at least the self-diagnosis (A) utterly. By shifting the timings for the A-system and the B-system to output the diagnosis pulses, independencies can be secured between respective diagnosis processing (self-diagnoses (A) and (B)). Thus, the independencies between the A-system and the B-system can be verified briefly by the self-diagnosis (A) on the A-system side. Further, first diagnosis pulse group are outputted parallel and simultaneously from first diagnosis pulse output means. Thus, since cyclic control is not required for respective external input devices, it can be done to verify the independencies between the A-system and the B-system within a short period of time.
