Abstract

Speed limiter system for vehicles. The system of the invention completely automatically prevents any vehicle equipped with it from exceeding the maximum speed allowed in the different sections of a road, city, etc. To do this, it has been provided that a radio frequency emitting device, associated with sending a coded signal, corresponding to each signal, is associated with the limiting and end-of-speed signals. The limiting device associated with each vehicle incorporates a cpu (6), associated with the control unit (7) of the vehicle, equipped with programming firmware to limit the injection of fuel into the engine according to the speed recorded by the speedometer (9). ), in order to prevent exceeding a pre-established speed level, which level is determined by the radio frequency signal emitted by each signal, and which is received by the device through a radiofrequency receiver module (10) associated with the cpu.

Description

Speed limiter system for vehicles.

Object of the invention

The present invention relates to a system which has been specially designed to totally avoid automatic than vehicles traveling on a certain route exceed the speed limit allowed and associated with said stretch.

The object of the invention is to avoid accidents that occur due to speeding.

The invention thus falls within the scope of Road safety.

Background of the invention

As is known, most accidents of traffic are due to speeding by vehicles.

Trying to solve this problem are used information campaigns as well as detection systems for speeding, such as fixed or mobile radars, that if well in some cases they have a deterrent character, not always They get the proposed effects.

It is true that on certain occasions said speeding may be due to a mistake by the driver, so while there are limiting devices for speed, these devices must be activated manually by users, who, due to lack of attention or distraction, may forget about connecting them, for example when crossing a population, or simply by being clueless and not seeing the corresponding signal of limitation for a certain section.

Description of the invention

The speed limiter system for vehicles that the invention proposes resolves in a fully satisfactory manner the problem described above, when acting on speed of the vehicle fully automatically.

To do this, and more specifically, in said system, each of the speed limiting signals are installs a radio frequency emitting device, in charge of emit an encoded signal, corresponding to the limit of speed set for each section of road.

Complementarily, at the end of said section, will establish the corresponding end of limitation signal of speed, equipped with another radio frequency emitting device, responsible for sending the corresponding end of prohibition.

Thus, each vehicle will incorporate a speed limiting device itself that receives said signals and acts accordingly.

The specific device comprises a CPU, equipped with a programming firmware to limit the fuel injection into the vehicle's engine through the electronic control of the injectors, for which said CPU is Connects to the vehicle control unit, being able to control it.

So the CPU will check the signals that register the switchboard, coming from the speedometer, acting on if necessary on the said injectors to prevent that the speed in question be exceeded in each case. For receive the aforementioned speed limitation signals, the cited CPU is associated with a radio frequency receiver module.

Optionally, the limiting device of speed may incorporate a GPS navigation module, associated with a road map storage memory, with the particularity that in said memory they are stored together with the roads drawn the maximum speeds allowed in each section.

Said GPS navigation module will be connected to the CPU, which acts on the switchboard and consequently on the speed of the vehicle depending on its position.

Finally, and according to another of the characteristics of the invention, the limiting device of speed itself may incorporate means of activation / deactivation thereof, as well as signaling means of its operating / inoperative state.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows a representation schematic of the different elements that participate in a system speed limiter for vehicles made in accordance with the object of the present invention.

Figure 2.- Shows an electrical scheme of the different modules that participate in the limiting device proper, associated with the vehicle.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as in the vehicle speed limiter system which is recommended, it is planned that in correspondence with each of the speed limiting signals (1) an associated radio frequency emitting device (2), responsible for sending a encoded signal, corresponding to the speed limit established for each section of road (3), so that, at at the end of said section the corresponding end signal will be established of speed limitation (1 '), to which it is also associated another radio frequency emitting device (2), this one in charge of send the corresponding prohibition end signal.

In this way, the vehicles (4) will be capable of incorporating a speed limiting device proper (5), responsible for receiving and processing said signs.

More specifically, and as you can observe in the diagram of figure 2, the limiting device of speed itself (5) comprises a CPU (6), associated with the vehicle control unit (7), CPU equipped with a firmware programming responsible for limiting fuel injection in the vehicle engine (4), through electronic control of the injectors (8), depending on the speed recorded by the speedometer (9), in order to prevent exceeding a speed level preset, and that will be determined by the signal of Radio frequency emitted by each traffic signal.

To do this, a CPU is associated with a radio frequency receiver module (10), the entire assembly being connected to a power supply (11) installed in the vehicle.

Optionally, the limiting device of Speed may incorporate a GPS navigation module (12), associated with a storage memory (13) of road maps, with the particularity that in said memory they are stored together with the roads drawn the speeds maximum allowed in each section.

Said GPS navigation module (12) will be connected to the CPU (6), which acts on the control unit (7) and consequently on the vehicle speed depending on the its position, recorded by the satellite (16), ensuring that it complies with traffic regulations or at least as far as refers to the preset maximum speed limit.

Finally, it should be noted that the device speed limiter itself incorporates means of activation / deactivation thereof, such as a switch (14) as well as means of signaling its operating / inoperative state, such as a warning light (15) that can be integrated into the control panel of the vehicle.
