Definitions

• the invention relates to a method for remote control of the locking / unlocking and starting functions of a motor vehicle by means of a mobile telecommunication device.
• the invention is concerned with an improvement in the remote starting process of the engine of a motor vehicle by means of a single authenticated mobile telecommunication device.
• the invention relates to the field of management and transmission of information and data between mobile devices called “smart devices” and motor vehicles.
• Some motor vehicles are today equipped with electronic, digital and software control systems capable and intended to manage in a secure manner requests for activation of various functions of the vehicle, received from remote mobile devices carried by the user. of the vehicle or passengers and paired or paired with the control system.
• control systems reconcile the information and data exchanged by short-range waves with identifying elements associated with the vehicle in question and recorded in mobile devices.
• the expression “mobile device” or “identifying element” will denote any means, element or equipment, authorized to activate the various functions of a motor vehicle. It can thus be a key, a badge, or any other means and, in particular, of the smartphone, digital tablet, connected watch type, etc., which, in the process of the invention or by implementing the process, will be authorized to trigger the command to activate the specific functions of the vehicle in question. More specifically, the identifying elements integrate codes which are recognized by the motor vehicle with which the mobile devices are paired to recognize each other. An exchange of data (for example according to a Bluetooth connection protocol) between the electronic control system of the vehicle and the identifying element makes it possible to achieve the execution of a command or a function on the vehicle, for example , unlocking the doors or starting the vehicle engine.
• the user and his mobile device must already be positioned inside the passenger compartment.
• the vehicle cannot connect on its own initiative to a mobile device and the decision to connect to the vehicle control system can therefore only be made by the mobile device.
• these existing control systems and methods do not allow the secure starting function of the vehicle engine to be controlled from a mobile device from outside and away from the passenger compartment.
• Document EP1336938 describes a system which makes it possible to identify the last mobile device connected to the vehicle to give it priority over the locking, unlocking and starting commands for the vehicle.
• a remote control method for starting a vehicle was the subject of a parallel patent application by the applicant. This process consists in widening the field of the detection and identification area of the mobile device by the on-board control system in order to ensure, at the same time, greater coverage and increased security for remote control of motor vehicle start-up.
• this method provides that the detection and identification area of the mobile device extends outside the passenger compartment by defining an extended coverage for receiving notifications sent by the control system to destination of this mobile device.
• this control method is not concerned with the problem relating to the selective sending of a notification for validation of the start-up to the only mobile device which has commanded the prior unlocking of the doors of the vehicle.
• the decision to display the notification before starting is taken by the vehicle.
• the specific technical problem in which the present invention is concerned therefore consists in finding a solution for selectively transmitting the start notification only to the mobile device which has previously ordered the unlocking of the vehicle.
• the present invention aims to solve the technical problems posed by the prior art by proposing a method for selectively displaying a start notification on the only mobile device which has just unlocked the vehicle and not on other devices mobiles present near this same vehicle.
• the message flow is sent periodically every 100 ms.
• control system communicates with said mobile devices according to a Bluetooth protocol.
• the flow of messages sent by the control system is encrypted and indicates to mobile devices that it is available for data exchange (so-called “advertising” mode).
• the control system does not authorize effective start until reception in return d 'a validation message.
• the method of the invention provides that the control system allows the engine to be stopped only on the instruction of the mobile device having previously ordered the start. In addition, if the mobile device having previously ordered starting leaves the vehicle after starting the engine, the control system sends it a warning message.
• Another object of the invention is a control system for the remote control of the locking / unlocking and starting functions of the engine of a motor vehicle using the method defined above.
• Yet another object of the invention is a computer program comprising instructions for the execution of the steps of a method as defined above.
• the invention also relates to a motor vehicle equipped with a control system allowing the implementation of the method as defined above for the remote control of the starting of the engine by means of a mobile telecommunications device.
• the improved method according to the invention thus makes it possible, at the same time, to avoid “polluting” other mobile devices, previously paired with the vehicle, with unnecessary notifications and, at the same time, to eliminate the risks of conflicts. validation in response to multiple parallel notifications.
• connection identifier in the stream of encrypted messages, called "advertising" makes it possible to ensure that only the mobile device having ordered the unlocking of the vehicle will connect to retrieve the request for display of the notification before starting.
• the improved method according to the invention allows, at the same time, a saving of execution time (a single connection against currently several potential connections depending on the number of paired devices), an improvement operational ergonomics (no untimely notification display on mobile devices potentially close to the vehicle but not involved in the start-up phase), better driver responsibility with regard to the start-up decision and a greater safety of the remote control.
• the improvement of the invention improves the relevance and the speed of display of the start-up notification.
• the method of the invention is intended for the remote control of the locking / unlocking and starting functions of a motor vehicle by means of mobile telecommunications devices.
• This method is implemented by means of a control system on board the vehicle and includes a step of receiving a command to unlock the vehicle from one of the mobile devices,
• the control system when the engine is running, the control system periodically broadcasts a continuous stream of messages (called “advertising" stream) that all mobile devices paired with the vehicle can decipher. These messages indicate the status of the vehicle in real time.
• the messages sent by the control system are encrypted and indicate to mobile devices that it is available for data exchange.
• the improved method of the invention provides that this stream of encrypted messages broadcasts, after opening the vehicle and before starting the engine, on the one hand, the connection identifier of the mobile device having previously ordered the unlocking of opening and, on the other hand, an invitation for this device to connect in order to receive a startup notification.
• the control system upon receipt of the unlocking command, the control system sends a stream of messages to the paired mobile devices connected to the vehicle which are simultaneously in its environment, in particular, that is to say those in possession of the driver or holder of the vehicle and passengers.
• the messages sent by the control system comprise, on the one hand, an identification data item of the mobile device having ordered the unlocking and, on the other hand, an invitation for this device to connect to receive a start-up notification.
• the method of the invention aims to selectively transmit the start notification only to the mobile device which has ordered the unlocking.
• the control system will only allow effective start-up upon receipt of a validation message from the selected mobile device.
• the decision to display the notification before starting is taken by the vehicle.
• control system will allow the engine to be stopped from the detection and identification area only by the same mobile device having previously ordered the initial unlocking and starting of the vehicle.
• the engine can then be started, either by traditionally placing the mobile device in the restricted "removal" area located inside the passenger compartment in the immediate environment of the system.
• on-board control either remotely from the vehicle from a single mobile device located in an extended detection and identification area which accepts, by sending a validation signal back, the notification sent by the system control.
• the control system sends successive signals to the selected mobile device to determine in real time its position relative to the vehicle, within a monitoring perimeter.
• the vehicle control system tracks the mobile device that was used to unlock and start the vehicle in a surveillance perimeter located in the detection area.
• this mobile device will receive start-up notifications, for example, every 100 ms, to confirm its presence in the detection zone of the control system and validate in response, if the user wish, a new start of the vehicle.
• the decision to connect to the vehicle control system is made by the mobile device.
• the vehicle cannot therefore connect on its own initiative to the mobile device.
• the decision to send a start notification to the mobile device must be previously registered in the vehicle control system in order to manage the priorities between the different start means. Thus, there is no notification sent in the presence of both a "hands-free" key and a mobile device.
• the dimensions of the reception area by the mobile device of notifications sent by the vehicle control system are a few meters and are compatible with the Bluetooth protocol used by the control system to communicate with the mobile device.
• This method always offers the driver or passengers the possibility of freely using the mobile device which has been used for the start control during the journey.
• control system can also authorize the engine to be stopped from the extended detection and identification area.
• control system Even if the mobile device leaves the detection zone after starting the engine, the control system considers that it is still present in this area, while the engine is still running. However, in such circumstances, the control system then sends a warning signal or message to the vehicle's interior handset.
