DE10342785A1 - Brake lights and turn indicating winking lights for road vehicle trailer have control system drawing current from battery on trailer and give flashing signal if vehicle connection is disconnected - Google Patents

Abstract

The trailer has a 12V or a 24V battery (4). This is connected to a control module (3) with a photocell. The amount of light received may control the action of a flashing warning light circuit (2). A plug (1) connects this circuit to the normal electric circuit of the trailer. The trailer lights may be actuated automatically if the electrical connection to the tractor vehicle is lost.

Description

Basic idea "increase in the Traffic safety ":

fuse single and multi-axle SOLO trailers or semi-trailers, the inevitable near or within traffic areas left without towing vehicle Need to become.

1. Basic technical forecast:

own electric 12V / 24V lighting system. Warning light, driving lights and possibly. Perimeter lighting. Power supply through 13pol./7pol. plug connection to the towing vehicle.

2. Additional facility:

installation a trailer's own Battery 12V / 24V at a suitable place (if not already available). installation the system described below.

3. The circuit:

The Circuit comes from a hazard warning lights, as well as a daylight controlled circuit, for switching on the Fz lighting when entering Dusk.

4th function:

The Emergency hazard warning system becomes electrical, mechanical and galvanic separated from the trailer's own Lights and hazard warning lights installed.

she can either as usual only from the coupled towing vehicle, or after separation from the coaches, through the new on-board supply cable of the trailer operate.

Both at the same time is not possible.

This sensory part of the system may be in the intended installation not affected by headlights of passing vehicles become..

The system is expandable
(eg operation by photovoltaic, alarm system, connection for warning light, etc.)

5. Battery capacity, charge:

For all trailers, the following applies: In the trailer order, the battery is removed from the towing vehicle via the contacts 10 (Permanent plus) and 11 (Mass for 9-13) loaded.

Alternatively, the battery can also over the lines 5 (right tail light) and 3 (Mass 1-8) of the driving light supply are loaded.

By a current limit (fuse 4A) in the charging line needs the Line protection of the lighting system in the towing vehicle should not be changed.

One Return current over the Charging line of the trailer battery in the electrical system of a possibly coupled towing vehicle becomes electronic through two intermediate power diodes prevented.

The on-board battery can also as usual after removal (strongly recommended !!) with a commercially available charger to be charged and maintained.

optional let yourself for caravans, truck trailers and semitrailers with solid construction also through the battery load a photovoltaic module.

6. Function performance:

The Performance of the battery should be the function of the system for one Ensure a period of up to 12h - night, Day / night, night / day. Empbhlen is the application of a battery in the order of magnitude that of the towing vehicle. A bungler in the order of 12V / 55Ah is intended for the intended Operating time sufficient.

Of the Operation of the onboard safety device by warning light unbind not on duty, accident site or traffic impairing Secure in the manner prescribed by StVO (warning triangles around.).

electrical function

• 1. The battery of the new emergency warning flashers will be operated by a towing vehicle via the contacts during operation 5 (Right tail light) and 3 = (Mass for 1-8) charged via a fuse 4A. Provided the parking or driving light in this configuration (operating situation !!) is turned on.
• 2. A small electronic circuit in the charging line prevents a power delivery of the trailer own battery into the electrical network of towing vehicle and trailer.
• 3. Without wertere internal connection is during driving on the emergency hazard warning lights only the 12V potential of the supply battery. (None Earth connection = no function)
• 4. After electrical and mechanical decoupling from towing vehicle, If necessary, the plug of the trailer hitch with the now pendant own Supply cable connected. At this moment receives the emergency hazard warning lights the ground contact required for the function and switches on automatically immediately. Depending on the brightness, the headlights plus any outline lighting, (optional also rear fog light) same or later.
• 5. The functional life depends on the performance of the battery.
• 6. The operation of the on-board safety device by warning light does not exempt you from the duty of having an accident site or traffic impairing Secure in the manner prescribed by StVO (warning triangles around.).
