Being the tachometer and the tachometer and

摘要

By continuously moving the pointer (11) on a (i) scale scale (10), the apparatus for a vehicle having a multi-gear transmission, indicating analogue tachometer display the number of revolutions per unit time of the vehicle engine and (8), to determine the expected engine speed at least one receives an input signal representing the vehicle speed and the actual engine speed and actual (ii), corresponding to the vehicle speed actually the on the basis of the ideal transmission gear ratio of at least one computer processing unit CPU and (12), as well as digitally displayed adjacent to the current position of the pointer (11), the gear number (15), the ideal gear of said at least one current corresponding to the current engagement gear is digitally displayed next to the scheduled engine speed of the response on the memory scale, the memory scale gear indicator display adjacent to (10) the ideal gear number corresponding to (16), and (14) contains. As an effect, the present invention can incite to be engaged with the optimal gear is achieved by displaying the results of the engine speed to engage the optimal gear with optimal gear.
