Description

Vehicle indicators for generating hazard warning light signals on the vehicle reversing lights.

The usual design of car indicators is an electrical circuit in a housing with connections for the positive pole, negative pole, operating switch and flashing light bulbs. When an operating signal is present at its inputs, the car indicator module generates a flashing signal at its output connection using an astable flip-flop.

The invention specified in claim 1 is based on the problem of creating a motor vehicle indicator to warn against wrong-way drivers, which causes the reversing lights to flash, but nevertheless primarily ensures that the reversing lights are continuously lit when the transmission is in reverse gear.

This problem is solved with the features listed in claim 1.

The invention enables motor vehicles in traffic to signal two different types of light signals via the vehicle reversing lights. A primary permanent light when reverse gear is engaged and a flashing light when the wrong-way driver warning is activated.

The inventor intends to produce his vehicle hazard warning lights and, after the introduction of the wrong-way driver hazard warning light in traffic law, to equip all registered motor vehicles with his product.

An embodiment of the invention is explained using Figures 1, 2 and 3. They show:

Fig.1 the car indicator in block diagram representation Fig.2 the electrical circuit diagram of the car indicator Fig.3 the car indicator module

The figures show the structure and interconnection of the electrical components of the vehicle indicator.

The astable flip-flop (1) generates the flashing signal. The OR switch (2) passes the flashing signal and, primarily, the continuous signal from the gear connection (5) to the relay (3).

A possible structure of the individual circuit components (1, 2, 3) is shown in the electrical circuit diagram in Figure 2. The astable flip-flop (1) is constructed with an IC component (timer NE555), capacitors and resistors. When the wrong-way driver warning light switch (10) is closed, input (6) receives voltage and a flashing signal is generated in the astable flip-flop (1). When the reverse gear switch (9) of the vehicle gearbox is closed, a continuous signal is generated at input (5). In the OR switch (2), diodes determine the direction of the signals and a transistor combines the two. An existing signal opens the transistor. This means that the continuous signal always has priority over the flashing signal. When the primary signal is present, the relay (3) switches the main current from the positive pole (4) to the reversing light connection (8). The individual components are connected to the negative pole of the vehicle battery via connection (7).

Figure 3 shows a possible housing structure for the vehicle warning light module, a closed plastic housing (11) with protruding flat plug connections for the inputs (4 to 7) and the output (8) of the electrical circuit.

Claims (1)

Dieter Cellarius, DCGHOST 01 p.1/1 Protection claims 1. Vehicle indicator, an electrical circuit in a housing (11) for generating warning light signals on the vehicle reversing lights, characterized, that an additional circuit input (5) is available for connecting the reverse gear switch of the vehicle transmission, which, when reverse gear is engaged, primarily generates a continuous signal at the indicator output (8) via an OR switch (2) and thus enables the display of the vehicle reversing signal.
