Definitions
- the present invention relates to the use of devices designed to transmit and receive radiofrequency data from a geolocation satellite module, or satellite guidance system (GPS, "Global Positioning System”), of selectively, and intended to equip motor vehicles to signal the occurrence of an imminent overshoot using an audible and / or visual alert.
- GPS Global Positioning System
- the goal is to secure dangerous overtaking.
- This use allows the reporting of the presence of at least one vehicle close to another, with assistance implementing the GPS data analysis.
- the exchange of GPS data allows passengers of the car receiving the signal transmitted by radiofrequency, to become aware of the imminence of an overrun based on reliable information.
- a radiofrequency communication system between different vehicles for exchanging data relating to their positioning is known from the patent application US20040061600.
- This type of system is designed to automatically activate alerts or automatically initiate actions, which must take effect in the receiving vehicle.
- such a system does not allow competitors to partially manage the data transmitted by the system, and to be able to override automated actions initiated subsequent to the receipt of these data.
- the present invention aims to allow the receiving automobile to exceed the request to improve the quality of decision making to take the appropriate measures to ensure overtaking in optimal safety conditions, such as alert between vehicles that all the passengers involved are well aware of the imminence of an overtaking.
- vehicle or “automobile” must be interpreted broadly in the context of the present invention and they include cars, trucks, motorcycles, quads, etc.
- the present application concerns, according to a first aspect, a method of assisting the passing of a vehicle in the context of an automobile race comprising the steps of:
- analyzing the geolocation data transmitted by the requesting vehicle from the receiving vehicle and depending on the relevance of the analyzed data, from the receiving vehicle, notify the pilot of the imminence of an overshoot and transmit manually or automatically, a radio frequency signal to the requesting vehicle, to prevent said requesting vehicle that the receiving vehicle has been made aware of the impending overshoot.
- Such a method implementing the GPS data analysis for the study of the relevance of a request for overshoot, facilitates the decision-making of the competitors of a car race through the filtering of radio frequency messages received. It also avoids triggering irrelevant alerts, which disrupt competitors, as is the case when the radio frequency module is not coupled to a GPS, the objective being to increase the safety of dangerous overtaking. More particularly, such a method provides an intelligence engine that makes it possible to take into account, or ignore, a request for overshoot, or an alarm, depending on the respective positions of the vehicles, their distance, caps and speeds and situations where there are more than two vehicles. This process is suitable both in rally and on circuit, to warn according to the level of danger presented by the zone where the overtaking is prepare. Such a method can be used to generate alarms for reporting danger situations other than overruns.
- the delay between two radiofrequency transmissions for the same request for overshoot (or an alarm) by the requesting vehicle is random and less than 250 ms (milliseconds), advantageously this delay is between 0 and 60 ms, and preferably this delay is between 20 and 40 ms.
- the requesting vehicle sends a message including its position (latitude and longitude), speed, heading, reference number, race number, category (truck, auto ...) and the overflow request indicator. An event is recorded in his journal. The very short message is sent in several bursts of several messages spaced by random delays to avoid collisions.
- the emissions are continuous every second, synchronized in time using the very precise time reference provided by the GPS module.
- the emissions are continuous every second, they are synchronized in time by using the very precise reference time provided by the GPS module, in order to avoid that the pilot has to report manually a request for exceeding.
- the synchronized automatic transmission on circuit allows each vehicle to have a map of nearby vehicles. This method is suitable for circuit operation, because the number of vehicles is limited and we want an automatic report. It is not adapted for the rally where the number of competitors can be of several hundreds, in this context the requests for manual overtaking are then preferred.
- the position will be advantageously characterized by the abscissa on the circuit calculated from the longitude and latitude data provided by the GPS (the transmission of the message is automatic once per second).
- a delay of at least 6 seconds must be observed in order to renew an overtaking request to the same receiving vehicle.
- the transmission of the same overflow request message is blocked for at least 6 seconds, which is automatically managed by a delay system interfaced with the motherboard serving as a bus between, inter alia, GPS and radio frequency modules. This delay prevents competitors from warning of overtaking all at the same time.
- a competitor issues a request for overtaking, another request can not be issued by the same competitor until at least 6 seconds after the previous one.
- no request for exceeding can be issued by the same automobile, except by an action that forces the request (as the press for more than 2 seconds on an override request button).
- Such an action can be logged, that is to say kept in memory to reconstruct the course of an event.
- the invention relates to a device for managing the overtaking between different vehicles of an automobile race incorporating:
- a radiofrequency transmission and reception module coupled to the geolocation module via a computer mainboard;
- a processor equipped with a system for memorizing the data acquired, and connected to the motherboard.
- Such a device is well suited for use during motor racing to warn overtaking or danger situations.
- the device according to the invention is provided more particularly for to equip the vehicles during the rallies, it then operates in manual override mode.
- This device is also well suited to equip cars on events on motor circuits, it then operates in request mode automatic overrun by continuous transmission of the position message.
- the competitors can, thanks to the manual actuator, make a request for overtaking, and, when within a certain time the competitors do not pay the request for overtaking, an automatic signal is sent thanks to an automatic actuator to signal that the competitor did receive the request, but did not validate it.
- the signaling means is a buzzer in rally. It is advantageously a beeper ("buzzer” or “beeper” in English) of more than 110 decibels, possibly supplemented with an LED lamp. On circuit, preferably, the signaling means is visual, it is advantageous to use an LED lamp or a small HD (high definition) screen of 3 to 3.5 inches and a quarter of VGA (in English: "Video Graphics Array ").
- the device according to the invention comprises two manual actuators which consist of a main remote button, for overflow requests, and a secondary remote button, for the activation of alarms.
- the alarm activation concerns dangerous situations, other than overtaking, such as accidents, blind falls or stops at the exit of the dune.
- the LED lamp seen previously in the context of the invention, can be used to make the distinction between a request for overshoot and an alarm.
- the buttons are remote, that is to say they are placed so that they can be accessed by both the pilot and his co-pilot in all circumstances (these buttons are not used on a circuit where the transmission by radiofrequency is continuous).
- the power supply is advantageously a triple input power supply (internal battery, external main power supply, external emergency power supply).
- the processor analyzes the data received in several steps consisting essentially of analyzes of the relevance of the geolocation data in terms of position and relative speed of the requesting vehicles. On the circuit, more precision is needed and the processor also compares the automotive profiles. These profiles are recorded during qualifying sessions. The analysis of these profiles and the comparison with the actual progression of the cars makes it possible to refine the calculation of the delay before passing and thus makes it possible to warn the pilot preferably 2 seconds before the overtaking.
- the screen is a transflective color screen (3 to 5 inches transflective) controlled by the motherboard, very high quality (quarter VGA type HD) and having a security indication display mode to serve as a signaling medium.
- a transflective color screen (3 to 5 inches transflective) controlled by the motherboard, very high quality (quarter VGA type HD) and having a security indication display mode to serve as a signaling medium.
- FIG. 1 shows the architecture of a device according to the invention.
- the device 1 whose architecture is visible in FIG. 1, comprises a box enclosing various elements, mainly:
- a GPS module 4 which provides the geolocation information at a programmable frequency of 2 to 10 Hz;
- radiofrequency module 7 which allows the signaling between a
- safety signaling means a buzzer 9 of high power (1 10 dB) and a flash 12;
- a processor 33 configured on the basis of a set of rules that analyzes any received message and studies: the validity of the message, the relevance; and which triggers (or not) the over or alarm signaling (audible or visual) as a function of the respective positions, heading and speeds and performance profiles for the circuit mode;
- a memory 36 for recording the trace provided by the
- GPS module and events such as: sending or receiving messages, acknowledgments; what serves in case of accident or litigation to analyze the situation.
- Device 1 is a security system, it is designed to operate autonomously, so it includes dual devices, which are: an external GPS antenna for precision and internal for security, an external power supply and an emergency power supply on internal batteries. In the event of an accident, as far as possible, it can continue to function.
- I / O security means In / Out to the security media: namely media that must work absolutely: buzzer, flash to report and button overflow and alarm for actions.
- This input / output stage is more secure, for example using connectors, than for other media that have no implication in the pilot safety.
- the applicant activates the override request button 15.
- the processor 33 collects in real time the GPS data which essentially concern the position, course and speed of the requesting vehicle. On circuit there is no need to activate a button because the transmission of the signaling message is continuous at the frequency of once per second.
- the applicant sends a message containing the following information: the name of the competitor, the number of the equipment, the position, the heading, the speed, and an indication that he is making a request for exceeded.
- This message is repeated three times, and between each repetition are interspersed short random delays to increase the robustness of the transmission.
- the message is sent as a broadcast (from one to all). On transmission circuit of this message is automatic once per second so there is no need to request manual override.
- All the devices 1 with radio range receive the message by the radiofrequency module 7.
- the receiving vehicles engage an analysis of the message received via the processor 33:
- the receivers activate the signaling "request for overrun "(in the case of circuit use, the message is ignored, and the next one is waited for, issued one second later).
- the GPS data are accurate (those received and their own data) but the applicant's speed is below a low threshold (6km / h configurable), the request is ignored.
- the processor activates or does not activate not the sound signaling.
- the receiver must inform the transmitter that the overtaking request has been signaled.
- This action can be manual (especially for trucks, cars in rally) by a brief press on the remote button acknowledgment 15, and within 6 seconds after receiving the request or automatic. It is automatic in the case of use on circuit, or for motorcycles in rally, or for cars and trucks in rally, if the manual acknowledgment has not been made.
- An acknowledgment message is then sent from the device 1 of the receiving vehicle.
- the device 1 of the overthrower requesting, receiving the "manual" acknowledgment, signals this acknowledgment by a brief activation of the buzzer 9 in the rally, or the flash 12 on the circuit.
- the transmitter will be warned by a message on the screen 27 if the vehicle to be overtaken is piloted by an inexperienced amateur pilot. This information is obtained through the competitor's number.
- the processor 33 controls the sending of an automatic acknowledgment from the radio module 7 of the device 1 of the receiving vehicle.
- the requesting vehicle then receives an automatic acknowledgment which is signaled to it by activation of the buzzer 9 with a specific sequence. He therefore knows that the request was received technically but that the receiving pilot did not acknowledge it.
- each device 1 all radio exchanges are logged and a trace is recorded. It is therefore possible to reproduce the deferred sequences in deferred time in case of dispute.
- the competitor decides to activate his alarm by pressing the alarm button 18. This operation is used in the case of rallies.
- the alarm can advantageously be given by the race controller equipped with a system and positioned on the edge of the circuit closest to the accident.
- a first analysis consists of checking the validity of the information received and activating the alarm report if the data is incorrect (this can happen if, for example, following a fall, the GPS antenna has been damaged).
- a speed check routine is activated. If you approach the speed limit, the buzzer 9 begins to "beep” until a continuous whistle when you reach the limit. When leaving the zone, the routine is deactivated.
- this mode is necessary for the update in a limited time of all the competitors (before the departure for example). These updates are done whenever there is a change in the route or parameters;
- the unloading dialog it allows to retrieve the trace and the events of each device 1;
- test dialog it allows to activate the signaling of a device 1 from computer hardware (PC). This function makes it possible to check the good functioning of the whole chain (radio and signaling media).
