Apparatus, key remote, and method for controlling operating conditions of a key module

A key partner for a transportation vehicle, the key partner comprising:

• a communication interface for radio communication with a key module for the transportation vehicle;
• and
• a control module for:
• controlling the communication interface,
• receiving, via the communication interface, a shutdown request of the key module,
• determining an authorization to shut down the key module based on whether a present state of the transportation vehicle permits shutdown of the key module, and
• transmitting, via the communication interface, a response to the shutdown request of the key module for the key module, wherein the response indicates whether the key partner authorizes the shutdown of the key module.

A method for a key module for a transportation vehicle, the method comprising:

• determining information about a key module motion;
• and
• controlling an operating state from a plurality of operating states of the key module based on the information about the key module motion, wherein the plurality of operating states comprises at least a first operating state, a pre-shutdown operating state and a shutdown state, by:
• activating the first operating state in response to the key module motion being above a motion limit value,
• activating the pre-shutdown operating state in response to the key module motion being below the motion limit value over a period of time,
• transmitting a shutdown request via a radio communication to a key partner of the transportation vehicle in response to the key module being in the pre-shutdown operating state, and
• shutting down the key module, in response to a response of the key partner of the transportation vehicle to the shutdown request indicating an authorization for shutdown of the key module while the key module continues to be in the pre-shutdown operating state.

A method for a key partner for a transportation vehicle, the method comprising:

• receiving, via a radio communication, a shutdown request of the key module;
• determining an authorization to shut down the key module based on whether a present state of the transportation vehicle permits shutdown of the key module;
• and
• transmitting, via the radio communication, a response to the shutdown request of the key module for the key module, wherein the response indicates whether the key partner of the transportation vehicle authorizes the shutdown of the key module.

A non-transitory computer readable medium including a program having a program code for performing a method for a key module for a transportation vehicle, when the program code is executed on a computer, a processor, a control module or a programmable hardware component the method comprising:

• determining information about a key module motion;
• and
• controlling an operating state from a plurality of operating states of the key module based on the information about the key module motion,
• wherein the plurality of operating states comprises at least a first operating state, a pre-shutdown operating state and a shutdown state, by:
• activating the first operating state in response to the key module motion le being above a motion limit value,
• activating the pre-shutdown operating state in response to the motion of the key module motion being below the motion limit value over a period of time,
• transmitting a shutdown request via a radio communication to a key partner of the transportation vehicle in response to the key module being in the pre-shutdown operating state, and
• shutting down the key module, in response to a response of the key partner of the transportation vehicle to the shutdown request indicating an authorization for shutdown of the key module while the key module continues to be in the pre-shutdown operating state.

• determining an authorization to shut down the key module based on whether a present state of the transportation vehicle permits shutdown of the key module;
• and
• transmitting, via the radio communication, a response to the shutdown request of the key module for the key module, wherein the response indicates whether the key partner for the transportation vehicle authorizes the shutdown of the key module.
