Instrument and vehicle employing same

Abstract

The invention discloses an instrument which comprises an instrument body, a plurality of display lamps and a controller, wherein an index dial comprises a scale area and is arranged on the instrument body, and the scale area comprises a plurality of scales and a plurality of light-transmitting areas corresponding to the scales; the display lamps are arranged in the instrument body and are opposite to the light-transmitting areas; the controller is used for determining the rotating speed range of a fuel consumption economic area and the rotating speed range of a high-fuel consumption alarm area according to a current output curve of an engine and controlling the lightening of the corresponding display lamps according to the rotating speed range of the fuel consumption economic area and the rotating speed range of the high-fuel consumption alarm area. The instrument disclosed by the embodiment of the invention can accurately display the rotating speed range of the fuel consumption economic area and the rotating speed range of the high-fuel consumption alarm area, the applicability of the instrument is improved, the cost is reduced, and the energy is saved. The invention also discloses a vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an instrument and a vehicle with the same. Background technique [0002] In the related art, most tachometers are pointer-type tachometers, and the pointer-type tachometers are roughly divided into four parts: a pointer, a dial, a motor and a driving circuit. Among them, such as figure 1 As shown, the dial prints the engine speed from 0 to the maximum value, so that the driver can read the engine speed according to the position of the pointer. Among them, the output torque of the engine increases with the increase of the engine speed, but after the torque value reaches the peak, the torque value will continue to decline, such as figure 2 As shown, so the engine speed works at the peak for a long time, which will improve the economy of fuel consumption. In order to remind the driver where the "peak" is, a green area will be printed on the dial (such as image 3 As shown in ar...

Problems solved by technology

[0003] However, the pointer tachometer in the related art can only meet the demand of a certain type of engine for a certain short time, but with the use of the engine, the output curve of the engine will change, resulting in the green area and red area on the dial after the change. zone will no longer be accurate

In addition, the output curves of different types of engines are also different after adjustment, resulting in different dials, which not only increases the cost, wastes energy, but also is prone to installation errors, which is not easy to install
