Embodiment Construction

[0019] As required, detailed embodiments of the present invention are disclosed herein. It is to be understood, however, that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The drawings are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0020] A description of illustrative embodiments follows.

[0021] refer to above figure 1 and figure 2 In the described system, if the key 2 is identified as being located in the vehicle 1 , it is generally also possible to start the vehicle 1 without actively using the key 2 by pressing the starter knob on the dashboard. To this end, it is tested whether the key 2 is visibly...

Abstract

The disclosure relates to a method to lock, unlock and start a vehicle without using a radio key or electronic vehicle key. According to the disclosure, the function of starting the vehicle without actively using the key is blocked when the vehicle is locked. When the vehicle is unlocked in a manner secured against relay station attacks, the possibility exists of starting the vehicle without actively using the key.

Description

technical field [0001] The invention relates to a method for locking, unlocking and starting a vehicle, in particular a motor vehicle, with a radio key or an electronic vehicle key. Background technique [0002] A keyless remote start system is a system for unlocking a vehicle without actively using a vehicle key (so-called passive vehicle unlocking) and starting the vehicle only by actuating a starter knob. For this, the user only needs to carry a radio key or an electronic vehicle key. If only passive vehicle unlocking is possible, this is called keyless entry. [0003] When a user approaches the vehicle or eg touches a door handle of the vehicle, the device installed in the vehicle wakes up and transmits a radio signal containing a coded interrogation signal to the radio key with a first frequency in the range of 30 to 300 kHz. Such as figure 1 As shown, the radio key decodes the interrogation signal, provides the interrogation signal with a new code and retransmits th...
