TACHOMETER AND GEAR INDICATING APPARATUS

摘要

This apparatus for a vehicle having a multi-gear transmission comprises (i) an analogue tachometer display device (8) indicating by continuously displacing a pointer (11 ) against a graduated scale (10) the number of revolutions per unit of time of a vehicle engine; (ii) a computer processing unit CPU receiving input signals representative of the actual engine speed and of the actual vehicle speed and determining at least one forecast engine speed corresponding to said actual vehicle speed, based on at least one speculated transmission gear ratio; and a gear indicator display (14) adjacent to the graduated scale (10) on which a current gear figure (15) corresponding to the currently engaged gear is digitally displayed next to the current position of the pointer (11 ), and a speculated gear figure (16) corresponding to the at least one speculated gear is digitally displayed next to the corresponding forecast engine speed on the graduated scale. In effect the invention can incite to engage the optimum gear which is achieved by displaying not only the optimum gear but also the consequence on engine speed of engaging the optimum gear.
