Embodiment Construction

[0019] figure 1 A side view of a vehicle 1 in which the invention is used is shown. The vehicle includes an instrument with a display unit 2 which is arranged in front of the driver in the immediate vicinity of the driver.

[0020] FIG. 2 schematically shows how the device according to the invention is arranged on the display unit 2 . The figure shows how two different embodiments of the invention are arranged on the display unit in the form of a speedometer 3 and a tachometer 4 . Furthermore, the display unit 2 has a number of different gauges, such as a time indicator 5, a fuel gauge 6, a transmission indicator 7, and the like.

[0021] Figure 3 shows a front view of a speedometer 3 arranged to indicate the speed of the vehicle 1, where the speed is shown in kilometers per hour (km / h).

[0022] A speedometer 3 is included in the display unit 2 . The speedometer 3 has a curved scale 8 delimited by a first outer circle 9 and a second inner circle 18 . Inside the arcuate s...

Abstract

Display device for indicating an operational state of a vehicle including a display unit, where the device shows graphical information on the display unit in the form of an arc-shaped scale and a number of numerals corresponding to the value of the operational state. The device includes an arc-shaped field with an extent from a first angle phi1 to a second angle phi2 and with an outer delimiting line that extends along the inside of the arc-shaped scale. The arc-shaped field is divided into a first segment A, which extends from the first angle phi1 to a third variable angle phi, and a second segment B, which extends from the third variable angle phi to the second angle phi2, where the third variable angle phi to the second angle phi2. The third variable angle phicorresponds to the relevant operational state of the vehicle and where phi1<=phi<=phi2, where the first segment A is arranged to assume a state that is visually distinguishable from the second area B.

Description

technical field [0001] The invention relates to a device for indicating the operating state of a vehicle according to the preamble of claim 1 hereinafter. Background technique [0002] In terms of motor vehicles, it is necessary for the driver to be able to read various operating states of the vehicle. According to known technology, motor vehicles are equipped for this purpose with some type of instrumentation in order to enable the driver to visually read said operating state, for example the speed of the vehicle. A common existing instrument is the speedometer, which shows the speed at which the vehicle is traveling, for example in kilometers per hour. Another common existing instrument is a tachometer, which shows the engine speed (engine speed) of the drive motor provided on the vehicle. [0003] In today's driver's environment with a lot of information, it is important for the driver to be able to fully understand the information given in the shortest possible time. ...
