CZ2011129A3 - Remote control system of vehicle door and cover locks - Google Patents

Abstract

The vehicle door and lid remote control system comprises a mobile signal transmitter (3) with at least one first control element (5) for separately controlling the boot lid (2) and a second control element (6) for unlocking the boot lid (2) located outside the vehicle (1). After locking the vehicle (1), it is possible to open the luggage compartment lid (2) separately by unlocking the second operating element (6) through the first operating element (5), leaving the other doors and lids locked. After such a separate opening and subsequent closing of the luggage compartment lid (2), the second control element (6) is again locked up after a specified time delay (Z). This allows the user to reopen the boot lid (2) during this time delay (Z) if he discovers after leaving the lid that he has left the mobile transmitter (3) in the luggage compartment.

Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a system for remote control of vehicle door locks and lids, which, after locking the vehicle, allows separate opening of the boot lid.

BACKGROUND OF THE INVENTION

Various remote control systems for door locks and vehicle lids are currently known. These systems have remote controls, generally integrated in the key, which allow the user to lock and unlock the vehicle from a distance from the vehicle, making it very easy to operate. If the remote control is not integrated directly in the key, it is usually on a common bundle. The remote control systems are either connected to the central locking system which controls the locks of all doors and lids simultaneously, or this function is integrated directly in them. A frequently used useful option in such systems is the addition of an additional control button to the remote control, which only controls the boot lid separately. Thanks to this function, the boot lid can be opened after the entire car has been locked, while the doors remain locked. Pressing the control button on the remote control either opens the lid directly or unlocks the control button located outside the vehicle, usually directly on the lid in the area of the grip handle. Pressing this button then unlocks the lock and the lid can be opened. This button is used to open the lid when the vehicle is unlocked, but is locked when the vehicle is locked. After the above-described separate opening of the boot lid and its subsequent closing (slamming), the lid is automatically locked immediately and the whole vehicle is again locked.

The disadvantage of such a system is the risk that the user, after opening the boot lid separately, leaves the remote control inadvertently in the boot when handling the load. When the lid is locked, the lid is immediately locked and the remote control in the vehicle is locked. Mostly doing so

happens that the user of the vehicle realizes that he does not have the remote control with him, realize just when the lid slams respectively. very soon after this slamming, but he has no chance of correcting this mistake and will remain at his own locked vehicle with no access to it.

Furthermore, the so-called keyless remote control systems of locks are known, in which the vehicle is equipped with a number of receivers monitoring the position of the mobile transmitter. If it approaches the vehicle, it will automatically unlock the vehicle. One of the sensors is also in the luggage compartment, and if it detects the presence of a mobile transmitter, it will not allow the lid to be locked. However, such systems are too expensive and complicated to be used only in expensive vehicles.

SUMMARY OF THE INVENTION

These drawbacks are overcome by the remote control system of the vehicle door locks and lids of the invention. The system comprises a mobile signal transmitter with at least one first control element for separately operating the boot lid and a second control for unlocking the boot lid lock and / or opening the boot lid located outside the vehicle. After the vehicle has been locked, the luggage compartment lid can be opened separately or the second control element can be unlocked by means of the first control element, while the other doors and lids remain locked. If the vehicle is equipped with an alarm, it is usually deactivated to prevent the alarm from being triggered by intrusion of the guarded area or by the activation of the shock sensor when handling the load.

However, after such a separate opening and then closing of the boot lid, the second control element is only locked again after a specified time delay. Thus, during the time delay after the lid slams, the boot lid can still be opened by means of the second control before it is again locked. This time delay allows the user of the vehicle to open the lid if he realizes that the mobile signal transmitter is not with him, but that he has probably put it in the trunk. The user thus releases the lid lock or the lock via the second control. opens the boot lid

The door will remain locked and the system will wait for the lid to close.

Preferably, the time delay is adjustable or completely deactivated by the user, for example in the vehicle control menu. This gives the vehicle user a choice of whether or not to use this function. the possibility to set a suitable delay yourself. This is easier for the user than if, for example, this function could only be set by a diagnostic tool and would have to be serviced with the vehicle for adjustment.

The time delay is preferably more than one and less than fifteen seconds. A shorter time delay would not allow the user to make use of the second control and a longer delay would increase the safety risk that the user would already be away from the vehicle so that an unauthorized person could access and open it. A time delay of four to five seconds appears to be particularly advantageous.

In a preferred embodiment, at least one lamp in the rear of the vehicle is activated for at least part of the time delay period. The user is thus warned that the vehicle is not fully locked and is therefore not fully secured by unauthorized use.

Advantageously, the time delay can be signaled by the flashing of at least a third stop lamp and the end of the time delay can be signaled by direction indicators. The third stop lamp is usually located substantially higher than the other lamps, often at eye level, and therefore the user notices its lighting not only in poor visibility, but also on a sunny day.

The end of the time delay is preferably signaled by an audible signal. The user is thus informed about the final security of the vehicle without having to observe it.

If a vehicle with a remote control system for door locks and vehicle lids according to the invention is provided with an alarm, it is at least partially deactivated upon opening the boot lid separately or unlocking the second control element by means of the first control element. After the lid is opened and closed, the alarm can be automatically re-activated at least partially after a time delay, that is to say below the locking of the second control. The partial activation of the alarm may include, for example, the activation of motion detectors in the interior of the vehicle, where the lid closure sensor is not yet activated.

In some cases, it may be more convenient to reactivate the alarm automatically when the lid is closed. If the lid is opened in the time delay by an authorized user, the alarm will trigger an alarm, but such a user can easily find the mobile signal transmitter and clear the alarm. Conversely, when opened by an unauthorized user, the authorized user is informed of the unauthorized intrusion and can return to the car from which it is only a few steps away.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 schematically illustrates a vehicle with a remote control system for door locks and lids of a vehicle according to the invention; and Figure 2 is a time sequence of system operation.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 schematically illustrates a vehicle 1 with a remote control system for door locks and lids of a vehicle according to the invention. The vehicle 1 has a luggage compartment lid 2, which is provided with a button 6 on its outer side in the region of the grip handle. The button 6 unlocks the luggage compartment lid lock (not shown). Furthermore, the vehicle 1 comprises a remote control 3 integrated in the ignition key, which is provided with a button 4 for unlocking and locking the vehicle and a button 5 for unlocking the boot lid 2 separately.

Fig. 2 shows the time sequence of operation of the system according to the invention. Depending on the time, the status of the button 5, the activation / locking of button 6 and its status, the position of the boot lid 2 and the state of the third brake light 7 are shown here. In this state, the button 6 is disconnected from the system and pressing it causes no operation of the lid lock. At moment A the user presses button 5 on the remote control 3, the system deactivates the alarm and connects button 6, which is usually signaled by the flashing of the indicator lights not shown. At moment B, the user presses button 6 as a result of which the system unlocks the boot lid lock and the user opens the lid. After handling the load, the user will latch the boot lid 2 at moment C. Button 6 is not locked by the system immediately, but only after a time delay Z, at time D. This time delay Z allows the user to

realizes that he apparently left the remote control 3 in the trunk of the vehicle 1 to press button 6 again at moment B 'and open the trunk lid 2.

In this case, the state of the system returns to B.

For the duration of the time delay Z, the third brake light 7 flashes to warn the user that the vehicle is not sufficiently locked and that the lid 2 can be opened again.

At the moment D, the flashing of the turn signals and the acoustic signal signal the end of this phase and the vehicle is fully locked. The delay time Z can be set by the user in the vehicle control menu or in another user-friendly manner.

If necessary, the user can also completely deactivate this time delay in this setting, then essentially the moment D coincides with C and the vehicle is completely locked as soon as the boot lid 2 slams.

The alarm is only fully activated at the moment D when button 6 is locked, opening the boot lid 2 in time delay Z does not cause an alarm. However, the system can also be adapted to trigger at least partial activation as soon as C lid 2 slams. For example, on vehicles with a sedan body, sensors monitoring the interior can already be activated because there is no risk of an alarm when lid 2 is reopened. however, at time C it can also serve as a security against unauthorized use during time delay Z. A user carrying the remote control 3 and leaving immediately after the boot lid 2 has slammed away from the vehicle would be informed of an unauthorized intrusion into the vehicle. the car. Conversely, if the remote control 3 really leaves the boot and the lid 2 slams, it can deactivate the alarm triggered by the remote control found after opening the lid 2.

Industrial applicability

The remote control system of the vehicle door locks and lids according to the invention can be used on vehicles with a separate remote control of the boot lid,
