Abstract

The present invention relates to an automotive with doors with a remote keyless system to permit or deny access to the automotive. The system comprises means to manually generate electrical power, which can be driven by the door handle.

Description

Automotive with manual electrical power generation
The present invention relates to an automotive with doors with a remote keyless system to permit or deny access to the automotive.
From the state of the art, for example DE 197 24 085 C1 or DE 100 38 152 A1 access systems for automotives are known, which are, however, not remote.
It was therefore the problem of the present invention, to provide an automotive with a convenient and safe access-system.
The problem is solved with an automotive with doors with a remote keyless system to permit or deny access to the automotive, whereas it comprises means to manually generate electrical power.
The inventive automotive comprises a remote keyless system to permit or deny access to automotives (RKE). Remote keyless systems operate by broadcasting radiofrequency waves and/or low frequency waves and in particular a frequency or frequencies, which are received by an RKE-receiver. The functions of a remote keyless entry system are contained on a keyfob or built into the ignition key handle itself. Remote keyless entry broadcasts a radio frequency and/or low frequency with a designated distinct digital identity code. In case, this code is identical with a code stored in the RKE-receiver, the RKE-receiver transmitts a signal to the door latch so that it is unlocked or locked or can be locked or unlocked. The comparison between the sent code and the stored code is done by an electrical control unit (ECU), which is connected to the latch of the car to eventually send a signal to the latch to lock or unlock the latch. The connection between the latch and the ECU can be via wires or wireless. Preferably, the RKE-receiver is part of the ECU. The ECU for the RKE can be part of the general ECU of the car or a separate ECU. In case it is a separate unit, it is preferably located in the door, most preferably near the latch.
The automotive further comprises means to manually generate electrical power. Due to the power generation, electrical energy can be provided to an electronic control unit (ECU) that comprises or is attached to the RKE-receiver and/or the door latch , so that at the ECU and/or the door latch are operable. This is especially desirable in case of a failure of the battery of the automotive or in other emergency cases in which no electrical energy can be provided to the ECU and/or the latch.
Preferably, the manual electrical power generation works by either manually putting the entire car, or more preferably, only a part of the car into motion. This motion is transferred to an electrical power generator, for example a dynamo, which generates electrical energy. Most preferably, the electrical power generator is actuated by actuating the door handle, preferably, by pulling and/or turning the door handle in and out.
Preferably, pulling and/or turning the door handle once, activates, wakes-up, the ECU, so that it can receive and process the radio frequency- and/or low frequency signal and send, if applicable, a signal to the door latch to open it.
In a prefered embodiment, the door handle is actuated several times so that not only the ECU is initiated (wake-up) but also energy is stored in an energy storage unit, which can be part of the ECU or remote from the ECU.
The storage unit can be connected to the lightning dynamo, that also provides electrical energy for example to the motor and the other electrical energy consumers of the automotive.
The invention is now explained according to figures 1 and 3.
These explantions do not limit the scope of the present invention.
Figure 1 shows one embodiment of the inventive vehicule.
Figure 2 shows the embodiment accordiing to figure 1 with an energy storage system incorporated into the ECU.
Figure 3 shows an embodiment where all the components are incorporated into the car door. Figure 1 shows parts of the inventive vehicle. This vehicule comprises at least one door 3 with a door latch 1 , to lock the door and a handle door 2 to open the door latch 1 manually. Furthermore, the car comprises an electrical control unit (ECU) 4, which comprises a RKE-receiver and an energy storage system charged by the vehicle. Furthermore, the car comprises a Keyfob 7 or any part alike, that is able to wirelessly communicate with the RKE-receiver 5 for example via radio- or low frequency 8. The keyfob 7 sends a signal 8 to the RKE-receiver 5, which transmits this signal to the ECU 6 where it is processed; i.e. where it is analysed whether the transmitted digital 8 signal matches with the stored signal in the ECU.
Based on this comparision, a signal is sent to the door latch 1 via wire 10 to unlock the door or the unlocking of the door is denied; i.e. no signal is sent to the door latch 1.
In case that the energy storage system 6 is empty, an electrical energy generating system, for example a dynamo, (not depicted) is actuated by pulling and/or turning the handle once. The person skilled in the art understands, that preferably the power generator can be actuated each time the handle is activated, regardless of the power status of the battery. This generated energy is transmitted via electrical wire 9 to the ECU and is at least sufficient to process the RF- and /or LF signal received and to send an electrical signal via electrical connection 10 to the door latch, so that the door can be unlocked. Afterwards, the battery can be charged by means known by person skilled in the art.
Figure 2 essentialy shows the embodiment according to figure 1. However, in this case, the ECU comprises an energy storage system. By pulling and/or turning the handle at least twice, not only a wake-up signal as in the embodiment according to figure 1 is transmitted to the ECU but more energy is generated, so that energy can be stored in the storage system 6. The person skilled in the art understands that the energy storage system can be also charged by the vehicule.
Figure 3 shows another embodiment of the inventive vehicle. In this case, all components are stored in the door of the vehicule, and the energy storage system is separated from the ECU. The ECU can be part of the entire door ECU. The system works as explained according to figure 2.
