An evaluation unit includes a front-rear acceleration sensor and an up-down acceleration sensor. The evaluation unit calculates a length of a track obtained by plotting detected front-rear and up-down accelerations on a three-dimensional space along a time axis within a period from gear shift start of an automatic transmission to gear shift end, calculate a track length per unit time by dividing the length of the track by a time interval from the gear shift start to the gear shift end, and evaluates that a gear shift shock is larger as the track length per unit time is longer.

The disclosure relates to a dual-mode bus which is operable on a guideway under automatic control and also operable on ordinary surface streets or highways under the control by a bus driver. The dual-mode bus comprises a rear axle having at both ends thereof traction wheels, a frame supported on the axle and a current collector. A floating support is connected between a differential gear housing of the rear axle and the frame and has two spaced portions, first one of which is disposed nearer to the axle than second one of the two spaced portions thereof. An arm having two spaced portions is provided, first one and second one of which are connected to the first and second portions of the floating support, respectively. The arm carries the current collector at a third portion spaced on the same side as the first portion of the arm, from the second portion of the arm. The third portion is spaced, further than the first portion of said arm, from the second portion of the arm. Two parallel links having the same length pivotally interconnects the corresponding portions of the arm and the floating support and means is provided for selectively urging the collector on the arm to its extended operative position and moving the collector to its stored inoperative position.

A guide arm is mounted via a ball joint to a support structure. A guide linkage, connected to the arm and foldable at its mid point, is also connected by a ball joint to the support structure. A second guide linkage guides the arm to a near vertical storage position when a motor folds the first linkage.
