PCT No. PCT/GB88/00382 Sec. 371 Date Feb. 15, 1990 Sec. 102(e) Date Feb. 15, 1990 PCT Filed May 16, 1988 PCT Pub. No. WO89/00517 PCT Pub. Date Jan. 26, 1989.A motor vehicle having a transmission comprising a clutch (14), a clutch control (18, 20) and a change-speed gearbox (12). The gearbox (12) has a plurality of mutually exclusively engageable gear ratios any desired one of which can be engaged by a manually operated gear lever (16) which comprises a shaft (33) pivoted at (34) and a hand knob (42) on a tube (40) rockably pivoted in force relatively to the shaft (33), a signal is sent to the clutch control (18, 20) causing automatic disengagement of the clutch (14). Further manual force on the tube (40) pivots the shaft (33) in direction (A) or (B) to the opposite side of a gear shift pattern. The clutch control (18, 20) receives a signal (54') that a new gear ratio has been engaged and automatically reengages the clutch (14). Clutch control (18, 20) includes a memory (68) which memorizes in which direction the gear lever (16) was pivoted to engage the currently engaged gear ratio, and disengagement of the clutch (14) when the tube (40) is rocked in the same direction as that in which the gear lever (16) was pivoted to cause the engagement of the currently engaged gear ratio. |
