## Abstract

A communication device for a vehicle comprises a plurality of communication means and a rule base. The communication device is designed to determine a communication means to use using said rule base. The communication device is further designed to: check with a remote server as to whether an update of the rule base is available, download the rule base update, and update the rule base using the downloaded rule base.

## Claims

### Claim 1

A communication device for a vehicle adapted to communicate with a remote server using one of a plurality of communication means; said communication device being on-board the vehicle and comprising a rule base to select a communication means to transmit data from the plurality of communication means; said communication device being adapted to determine a communication means of the plurality of communication means to use using said rule base; said determination being made as a function of on one or more of the following: a criticality of the data to be transmitted, price of communication, time period at which the data is to be transmitted, and a location of the vehicle at the time of transmission of data, wherein, the communication device is further designed to:
check with said remote server when the vehicle starts up as to whether an update of the rule base is available,
download the rule base update, and
update the rule base using the downloaded rule base;
after transmission of a data frame; save data related to the communication, the data related to the communication comprising one or more of the following: the communication means used for the communication, a bandwidth, a latency, an error rate, geolocation data indicating the position of the vehicle at the time of transmission, and a size of the file or files transmitted; and
transmit the data related to the communication to the remote server for use by the remote server for updating the rule base.

### Claim 2 (depends on 1)

The communication device according to claim 1, wherein the communication means comprises at least one of the following: Wi-Fi, 2G, 3G, 4G, 5G LTE cellular network or satellite link.

### Claim 3 (depends on 1)

The communication device according to claim 1, wherein the communication device is adapted to transmit data comprising a security message intended for an infrastructure or for another vehicle.

### Claim 4 (depends on 1)

A vehicle comprising the communication device according to claim 1.

### Claim 5

A communication method for a vehicle comprising one or more computers which control functions of the vehicle and a telematics computer comprising a memory and a communication device adapted to transmit data by way of a plurality of communication means for transmitting data; said telematics computer storing a rule base for selecting a communication means from among the plurality of communication means, the method comprising the steps of:
the telematics computer checking with a remote server as to whether an update of the rule base is available upon startup of the vehicle and downloading the update of the rule base if an update is available;
the telematics computer receiving a communication request to transmit a data frame comprising functional information related to the vehicle;
the telematics computer determining a communication means to select using said rule base; said determination being based on one or more of the following: a criticality of the data to be transmitted, price of communication, time period at which the data is to be transmitted, and a location of the vehicle at the time of transmission of data;
the telematics computer establishing communication with the selected communication means and transmitting said data frame;
the telematics computer saving data relating to the communication, the data related to the communication comprising one or more of the following: the communication means used for the communication, a bandwidth, a latency, an error rate, geolocation data indicating the position of the vehicle at the time of transmission, a size of the file or files transmitted; and
the telematics computer transmitting said data relating to the communication to said remote server.

### Claim 6 (depends on 5)

The communication method of claim 5 further comprising:
checking with the remote server as to whether an update of the rule base is available,
downloading of the rule base update, and
updating the rule base stored on a computer of the vehicle using the downloaded rule base.

### Claim 7

A communication system comprising a remote server and at least one vehicle; said remote server storing a communication rule base, and said at least one vehicle comprising one or more computers which control functions of the at least one vehicle and a telematics computer adapted to communicate with said remote server and comprising a memory and a communication device adapted to transmit data by way of a plurality of communication means for transmitting data; said telematics computer storing a rule base for selecting a communication means from among the plurality of communication means, wherein said telematics computer is adapted to:
upon startup of the at least one vehicle, check with the remote server as to whether an update of the rule base is available and download the updated rule base if an update is available;
receive a communication request from the one or more computers to transmit a data frame comprising functional information related to the vehicle;
determine a communication means to use to transmit said data frame using said rule base; said determination being based on one or more of the following: a criticality of the data to be transmitted, price of communication, time period at which the data is to be transmitted, and a location of the vehicle at the time of transmission of data;
establish communication with the remote server using the selected communication means and transmit said data frame;
save data relating to the communication, the data related to the communication comprising one or more of the following: the communication means used for the communication, a bandwidth, a latency, an error rate, geolocation data indicating the position of the vehicle at the time of transmission, a size of the file or files transmitted; and
transmit said data relating to the communication to said remote server;
wherein the remote server is adapted to update the rule base stored on the server using the data relating to the communication transmitted from the at least one vehicle.
