Description

Method for remotely controlling the automatic steering of a motor vehicle

Technical Field

The present invention relates to the field of motor vehicle technology, and more particularly to a method for remotely controlling automatic maneuvering of a motor vehicle.

Background

Currently, a user may activate a function of a motor vehicle even when the user is away from the motor vehicle. For this purpose, the user has a remote control, for example an electronic key. The function concerned may be, for example, the locking or unlocking of a door of a motor vehicle.

Such remote control devices can also be used to trigger automatic operation of the motor vehicle equipment or of the motor vehicle itself. The automatic operation may be, for example, opening or closing of a door, or a parking operation.

Remote control devices are often provided with control members, such as buttons. In order to ensure the safety of such automatic actuation, provision is made for the automatic actuation to be carried out as long as the holding button is pressed and for the automatic actuation to be interrupted when the button is released. The purpose of this manner of proceeding is to ensure that the user knows that automatic manipulation is being performed.

However, it may be that the automatic manipulation is accidentally triggered. For example, when the control device is in a pants pocket, pressure may be accidentally applied to the button. The user may then not know that an automated manipulation is being performed, which represents a risk, since in this case the user is not monitoring the performance of the automated manipulation.

Disclosure of Invention

The present invention aims to solve the problem just mentioned by proposing a control method that makes it possible to verify the responsiveness of the user when the automatic manipulation is triggered.

To this end, the invention relates to a method for remotely controlling automatic maneuvering of a motor vehicle by means of a remote control device comprising a plurality of control members for motor vehicle functions, the automatic maneuvering being triggered by actuating the control members of the remote control device in a predetermined sequence.

According to one embodiment, the predetermined sequence comprises the following successive operations:

-actuating the first control member;

-actuating the second control member before expiry of the first predetermined delay.

According to one embodiment, the first control member and the second control member are push buttons, the first control member being kept pressed for more than a first predetermined time, the first predetermined delay starting when the first control member is released.

According to one embodiment, a warning signal is generated when the first predetermined time elapses.

According to one embodiment, the first predetermined time is in the range of 100ms to 500 ms.

According to one embodiment, the first predetermined delay is in the range of 1s to 30 s.

According to one embodiment, the automatic manipulation is performed as long as the second control member remains depressed, the automatic manipulation being interrupted when the second control member is released.

According to one embodiment, the automatic steering resumes when the second control member is actuated again before the expiration of the second predetermined delay.

According to one embodiment, the automatic manipulation is performed when the second control member is released, and the automatic manipulation is interrupted when the second control member is actuated again.

According to one embodiment, the automatic steering is interrupted as soon as any one of the control members other than the second control member is actuated.

According to one embodiment, the method comprises the step of detecting a failure of the first control member, the failure corresponding to an actuation time of the first control member being greater than a second predetermined time, wherein the actuation of the first control member is not considered to belong to the predetermined sequence.

Drawings

The invention and its various applications will be better understood by reading the following description and by studying the single drawings, which schematically show examples of the background of application of the invention. The drawings are only for purposes of illustrating the invention and are not to be construed as limiting.

Fig. 1 shows a motor vehicle 1 and a remote control 2 for automatic steering of the motor vehicle 1. The control device 2 is produced, for example, in the form of a remote control.

Detailed Description

In the context of the present invention, "automatic maneuvering of a motor vehicle" is understood as: the maneuvering of the motor vehicle itself, i.e. maneuvers involving displacement of the vehicle, such as parking maneuvers; or the operation of motor vehicle equipment, such as the opening or closing of doors, tailgates or roofs.

The control device 2 comprises, for example, three

control members

21, 22, 23 for the so-called "static" function of the motor vehicle 1. In this example, the first control member 21 is dedicated to the locking and unlocking of the tailgate of the motor vehicle 1, the second control member 22 is dedicated to the locking of the side door of the motor vehicle 1, and the third member 23 is dedicated to the unlocking of the side door of the motor vehicle 1. Preferably, the

control members

21, 22, 23 are buttons. The function of the motor vehicle 1 can be triggered by a click on the

control member

21, 22, 23.

As is known, the control device 2 communicates with a control unit 14 equipped with the motor vehicle 1 by means of radio frequency waves. The control unit 14 makes it possible to convert the actuation of the

different control members

21, 22, 23 into performing one or more functions on the motor vehicle 1.

According to the invention, the automatic steering is triggered by actuating the

control members

21, 22, 23 in a predetermined sequence. Thus, the intention of the user of the motor vehicle 1 to trigger an automatic manoeuvre can be demonstrated. The fact that the

control members

21, 22, 23 are actuated in a certain sequence enables control to be obtained with a low probability of failure, resulting in high reliability. It is practically impossible to accidentally complete the actuation sequence of the

control members

21, 22, 23.

According to one embodiment, the predetermined sequence is initiated by pressing the first button 21 for a long time, and then completed by pressing the second button 22 before the first predetermined delay has elapsed from the moment the first control member 21 is released. If the second button 22 is not actuated within the allotted time, the automatic manipulation will not be triggered. The first delay is preferably in the range of 1s to 30 s.

In the context of the present invention, "long press" is understood to mean that the button remains pressed for more than a first predetermined time. Conversely, the click corresponds to the button being actuated for less than a first predetermined time. The first predetermined time is, for example, in the range of 100ms to 500 ms.

Advantageously, a warning signal is generated when the first predetermined time has elapsed, to indicate that the first button 21 can be released. The warning signal is for example an audible signal, a visual signal, a vibration or a combination of the three.

Advantageously, a step of detecting a failure of the first control member 21 is provided. For this reason, it is checked whether the first control member 21 is not kept pressed for more than the second predetermined time. This time is for example equal to the maximum value of the first predetermined time plus an offset to distinguish faults that are triggered as unexpected sequences. The offset may be in the range of 100 to 1000 ms. When the first control member 21 is defective, its actuation is not considered to form part of the sequence. This detection step may ensure that the sequence is not accidentally initiated.

In the context of the present invention, the term "failure" covers failures of a physical nature, such as mechanical blockages or short circuits of the control member, as well as actions that accidentally actuate the control member.

Preferably, the automatic manipulation is performed as long as the second button 22 is kept pressed, and the automatic manipulation is interrupted if the second button 22 is released. Advantageously, the automatic steering may resume its execution when the second control member 22 is actuated again before the expiration of the second predetermined delay. Thus, the user of motor vehicle 1 can instantaneously release the pressure exerted on second push-button 22, for example in the event of his or her distraction, without having to restart the sequence from the beginning. The second delay is preferably in the range of 1s to 30 s. The second delay is set equal to the first delay, for example.

According to another embodiment, from the moment the second button 22 is actuated, an automatic manipulation is performed even if the second button 22 is released. Thus, the automatic manipulation may be triggered by clicking on the second button 22 and continued upon release of the second button 22. In this case, the automatic manipulation can be interrupted by pressing the second button 22 again. The automatic steering can then be resumed by pressing the second button 22 again.

Whichever embodiment is employed, an emergency stop procedure for the automated maneuver is advantageously provided to enhance the safety of the automated maneuver. The emergency stop may be performed by pressing any of the

buttons

21, 23, including the second button 22, when the second button 22 is not pressed at that particular moment. This makes it possible to perform an emergency stop in the fastest time in an emergency.

Several sequences may be provided to trigger different automated manipulations. In this case, the first control member 21 for starting the sequence serves as a common reference for all sequences. One advantage is that it is convenient to remember the sequence.

According to one embodiment, following the actuation of the first control member 21, the actuation of the second control member 22 is dedicated to a so-called "forward exploration" maneuver, during which the motor vehicle 1 advances as long as the second control member 22 is actuated, or until the motor vehicle 1 detects an obstacle. In this embodiment, again following the actuation of the first control member 21, the actuation of the third control member 23 is dedicated to a so-called "reverse exploration" maneuver, during which the motor vehicle 1 reverses, as long as the second control member 22 is actuated, or until the motor vehicle 1 detects an obstacle.

According to another embodiment, other manoeuvres may be assigned to the second and

third control members

22, 23, such as a manoeuvre to stop the motor vehicle in a parallel, scattered or angled parking space, which can be performed in a forward or backward mode.

Naturally, the invention is not limited to the embodiment just described and modifications can be envisaged without departing from the scope of the invention. It is possible in particular to construct a sequence comprising more than two control elements to be actuated.
