Definitions
- the present invention relates to methods and devices for stopping a moving vehicle.
- the present invention also relates to a computer program comprising instructions for the implementation of one of the methods, a recording medium readable by a computer on which is recorded a computer program comprising instructions for the execution steps of one of the methods and a vehicle comprising one of the devices.
- ADAS Advanced Driver-Assistance System
- Level 1 provides driving assistance that allows direction or acceleration and deceleration control
- Level 2 allows partial automation with one or more driver assistance systems that control both steering and acceleration and deceleration functions
- Level 3 allows control of all aspects of dynamic driving, but requires the driver to intervene appropriately when asked to intervene;
- Level 5 allows human control of all aspects of dynamic driving at all times, in all road conditions.
- the ADAS systems most commonly implemented in current vehicles allow lane keeping (LKA, from the English “Lane Keeping Assist”), the triggering of an alert during an involuntary lane change (LDW from the English “Lane Departure Warning”), the triggering of imminent collision alert (FCA for "Forward Collision Assist”).
- LPA Lane Positioning Assist
- SALC semi-automatic lane change systems
- ABS anti-lock braking assistance systems
- AEBC emergency braking assistance systems
- ESP Electronic Stability Program in English
- ACC adaptive cruise control
- ADAS systems can happen that a driver forgets to stop his vehicle correctly, for example by applying his handbrake or by going to cut his engine. The vehicle can then be in motion without any driver. It can also happen that the driver is inside the vehicle but unable to stop the moving vehicle because he is unconscious for example.
- the object of the present invention is in particular to stop a moving vehicle when this vehicle is not controlled by a driver. Summary of the present invention
- An object of the present invention is to stop a moving vehicle in the absence of a driver or when this driver is unable to stop the vehicle.
- Another object of the present invention is to improve road safety.
- the present invention relates to a method for stopping a moving vehicle, said method comprising the following steps:
- the time count is stopped and the information is no longer disseminated.
- the selected action is stopped or the actions of 'a combination of selected actions are stopped.
- the alert is audible.
- the alert is visual.
- the visual alert indicates the time countdown.
- the present invention relates to a device for stopping a moving vehicle, the device comprising a memory associated with a processor configured for the implementation of the steps of the method according to the first aspect of the present invention.
- the present invention relates to a vehicle, for example of the automobile type, comprising a device as described above according to the second aspect of the present invention.
- the present invention relates to a computer program which comprises instructions adapted for the execution of the steps of the method according to the first aspect of the present invention, this in particular when the computer program is executed by at least one processor.
- Such a computer program can use any programming language, and be in the form of source code, object code, or intermediate code between source code and object code, such as in a partially compiled form, or in any other desirable form.
- the present invention relates to a computer-readable recording medium on which is recorded a computer program comprising instructions for the execution of the steps of the method according to the first aspect of the present invention.
- the recording medium can be any entity or device capable of storing the program.
- the support may comprise a means storage, such as a ROM memory, a CD-ROM or a ROM memory of the microelectronic circuit type, or even a magnetic recording medium or a hard disk.
- this recording medium can also be a transmissible medium such as an electrical or optical signal, such a signal being able to be conveyed via an electrical or optical cable, by conventional or hertzian radio or by self-directed laser beam or by other ways.
- the computer program according to the present invention can in particular be downloaded from an Internet-type network.
- the recording medium may be an integrated circuit in which the computer program is incorporated, the integrated circuit being adapted to execute or to be used in the execution of the method in question.
- FIG. 1 schematically illustrates a driving environment of a vehicle, according to a particular and non-limiting embodiment of the present invention
- FIG. 2 schematically illustrates a device for stopping a moving vehicle, according to a particular and non-limiting embodiment of the present invention
- FIG. 3 illustrates a flowchart of the different steps of a method for stopping a moving vehicle, according to a particular embodiment of the present invention.
- a non-zero speed of the vehicle and an absence of pressure from at least one hand of the driver on the steering wheel of this vehicle are detected.
- a time countdown is triggered. This time countdown is initialized to a determined value. Throughout this time count, an alert is triggered inside the vehicle to broadcast information in the vehicle asking the driver of the vehicle to apply pressure on the steering wheel of the vehicle for a second determined duration, and to reduce the vehicle speed of a specified number of kilometers per hour.
- an action or a combination of at least two actions is selected from the following actions: control of a braking system of the vehicle to stop the vehicle; cutting off the vehicle engine if it is running; locking vehicle doors and windows; control of vehicle hazard warning lights ignition means; triggering of a vehicle alarm siren; and, if the vehicle is connected to a communication network, sending a notification to the driver to inform him of a state of the vehicle and of a geographical position of the vehicle.
- the vehicle can thus stop automatically even in the absence of the driver or if the driver is unable to stop the vehicle.
- Road safety is thus improved because the present invention prevents uncontrolled vehicles from being in motion.
- the present invention is advantageous because its implementation uses means already on board the vehicle such as its braking systems, warning means or even means for lighting hazard warning lights, and the control of these systems or means can be implemented by one of the computers already on board the vehicle.
