Display device for driver's cab signals with target and Actual speed display for vehicles, in particular rail-bound locomotives

The innovation concerns a display device for driver's cab signals with target and actual speed display for vehicles, in particular rail-bound locomotives.

So far, the exact value of the specified target speed is displayed, which gives the vehicle driver the Task falls to the tolerance range, i. H. the permissible overshoot or undershoot of this value by the Estimate actual speed yourself. The result is often an uneconomical and unsafe driving style. Of the PA 9/414/609

The innovation is based on the task of the vehicle driver from estimating what is permissible for the driving style of the vehicle Tolerance range of the actual speed and any additional tolerance ranges for initiated control processes, z. B. Braking or accelerating to free "

According to the innovation, this object is achieved in that for the target speed display a below a slotted scale playing two-dimensional pointer with a strip-shaped Display area is arranged, each of which is more visible depending on the pointer deflection of different lengths Section marked a target speed range to be observed. According to another partial feature of the innovation, it is It is advisable to provide other colored stripes directly next to the stripes for the target speed display, whose cutouts visible in the slot scale are adjacent areas for speed control processes, e.g. B. different Mark the levels of acceleration or deceleration that are required when the actual speed deviates from the target speed range.

Further 'partial features of the innovation are based on the following an embodiment shown in the drawing for a speed display device.

Fig. 1 shows the front view of the target and actual speed display device.

Pig. 2 shows the course of the strip-shaped display areas, which can be attached to the surface of a drum or to the tape of a tape indicator.

Figures 3 to 5 show schematically !! different Options for adjusting the flat pointer.

In Fig. 1 are two adjacent slots and J

to display the target speed V and the actual speed

age V. provided. The speed V. is here by the end of a at 0 km / h. beginning band-shaped Pointer Zi displayed. The target speed range is by an areal playing under the slot S. Pointer Zs with a strip-shaped display surface sw (Fig. 2) displayed, depending on the pointer deflection in the slot S. Section A of a given length is visible. This section marks the target speed range to be observed. If the actual speed is within this range, the driver can let the vehicle roll freely. An area is marked by the adjoining section V of the strip rt, which when it is reached by the actual speed the vehicle driver decelerates the vehicle, e.g. B. by. Activation of the first of several braking levels, trigger got to. If the actual speed also exceeds this range, it can be seen that the braking is even stronger is required.

In a corresponding manner, the section B of the Stripe bl marks an area, "when it is reached through the actual speed the first "acceleration stage or if it falls below this, the next higher acceleration level must be switched on.

To mark the sections A, B and Y, as shown in FIG. 3 a drum T can be used, which is about an axis parallel to the slot S corresponding to the mean setpoint speed is rotated. On the outer surface Ft of this drum, the directly adjacent ones run strip-shaped display areas bl, bw and rt in diagonal Direction. The width of these strips and thus the visible length of the cut-outs are to be taken into account by the Operating conditions, e.g. B. Braking and acceleration, medium target speed range, economical driving style etc., given.

The strip-shaped display areas are expediently executed in different colors, z. B. blue (bl), black (sw) and red (rt). There is always only a small section of the stripes is visible through the slot S, the areas for target speed, deceleration and acceleration seem to wander along the scale and change their width when the display drum is rotated.

Pig. 4 schematically shows an embodiment of the display device with a display tape Pb on which the strip-shaped display surfaces are appropriate, depending on the mean target speed is adjusted transversely to the slot S by means of the rollers W1 and W2.

Pig. 5 shows schematically a display device with a coordinate drive. Here are the strip-shaped display areas bl, sw and rt arranged on a character carrier Pk, corresponding to the mean target speed in the longitudinal direction of the slot S and by means of guides, for. B. one stationary groove N and a pin Mj attached to the character carrier is adjustable across the slot.

For the easy observation of additional message and command displays by the vehicle driver, it is expedient to provide optical display devices 1 to 8, in particular lamps, in the immediate vicinity of the speed scales. These additional signals can, for example, be special commands that provide information about the type of journey, e.g. maneuvering or normal driving, or the permissible deceleration value. It can also be useful to install additional display devices for the operational

readiness, the vehicle or train length and other vehicle properties to be provided in the display device.

The use τοη two separate slots S and J to compare 'the actual speed with the displayed Ranges of the target speed is not necessary. It is also possible to "make both displays in one slot, if namely "for example the" ribbon-shaped pointer for the The actual speed is displayed on the flat pointer is arranged for the display of the target speed and consists of a transparent material.

To indicate several levels of acceleration and / or deceleration, additional stripes can also be used Display areas on the flat target speed range pointer to be appropriate.
