CONSTITUTION:Each output signal is inputted into an ECT computer 50 from a car speed sensor 110 and a shift p...

PURPOSE:To reduce time lag at starting so as to improve the feeling of a driver by shifting a clutch to a gear stage set in advance when the car speed becomes in the range of set value after releasing an acceleration pedal. CONSTITUTION:In an electronic control circuit 31, when detected that an engine revolution number is below the rated idling number by an engine revolution sensor 32, a clutch ac...

PURPOSE:To make emergency starting at the time of trouble in a vehicle smoothly performable, by setting the relationship between an accelerator pedal operating quantity and a fuel supply down to a nonlinear form. CONSTITUTION:When trouble occurs in an electronic controller 1 and a vehicle becomes undrivable, a power source is selected to an emergency controller 2 by a power selector switch 14, mak...

PURPOSE:To promote the improvement of fuel consumption and acceleration characteristic, by providing an external signal setter, in which the driver enables an output signal, able to be added to and subtracted from a vehicle speed signal, to be optionally set and output, so that the driver can select a speed change point by his will. CONSTITUTION:A CPU5e in a control unit 5 reads a car speed from a...

PURPOSE:To make the device compact, and improve the life of a belt, by carrying out continuous speed change by a V-belt type continuously variable mechanism during forward running, carrying out power transmission by gears with a fixed gear ratio during reverse running, and arranging gear trains for driving, forward running and reverse running in a line.
