1. A control unit for a vehicle, wherein the control unit is configured to:
- receive and/or transmit one or more safety-related vehicle cooperation messages via a physical channel of a communication unit of the vehicle;
administer a logical control channel for receiving and/or transmitting the one or more safety-related vehicle cooperation messages via the physical channel;
administer a logical service channel for receiving and/or transmitting one or more non-safety-related vehicle cooperation messages via the physical channel; and
assign the physical channel of the communication unit either to the logical control channel for receiving and/or transmitting the one or more safety-related vehicle cooperation messages or to the logical service channel for receiving and/or transmitting the one or more non-safety-related vehicle cooperation messages,receive sensor data from one or more sensors of the vehicle,determine a probability of a risk of conflict with another road user in a first time period on the basis of at least one of the received sensor data and received safety-related vehicle cooperation messages;
if the determined probability of the risk of conflict is below a predefined threshold value, assign the physical channel, which is otherwise reserved for the logical control channel to exchange safety-related vehicle cooperation messages, by a temporary changeover in the first time period at least partially to the logical service channel; and
receive and/or transmit a non-safety-related vehicle cooperation message via the physical channel of the communication unit of the vehicle when the physical channel is assigned to the logical service channel.

Abstract
An efficient implementation of intelligent transportation systems is provided. A control unit for a vehicle is designed to receive and/or to transmit a safety-relevant vehicle cooperation message via a physical channel of a communication unit of the vehicle. The control unit is designed to determine an indication of the vehicle having a reduced risk of conflict with another road user in a first period of time. The control unit is designed to receive and/or to transmit a non-safety-relevant vehicle cooperation message via the physical channel of the communication unit of the vehicle in the first period of time.

-
receive and/or transmit one or more safety-related vehicle cooperation messages via a physical channel of a communication unit of the vehicle; administer a logical control channel for receiving and/or transmitting the one or more safety-related vehicle cooperation messages via the physical channel; administer a logical service channel for receiving and/or transmitting one or more non-safety-related vehicle cooperation messages via the physical channel; and assign the physical channel of the communication unit either to the logical control channel for receiving and/or transmitting the one or more safety-related vehicle cooperation messages or to the logical service channel for receiving and/or transmitting the one or more non-safety-related vehicle cooperation messages, receive sensor data from one or more sensors of the vehicle, determine a probability of a risk of conflict with another road user in a first time period on the basis of at least one of the received sensor data and received safety-related vehicle cooperation messages; if the determined probability of the risk of conflict is below a predefined threshold value, assign the physical channel, which is otherwise reserved for the logical control channel to exchange safety-related vehicle cooperation messages, by a temporary changeover in the first time period at least partially to the logical service channel; and receive and/or transmit a non-safety-related vehicle cooperation message via the physical channel of the communication unit of the vehicle when the physical channel is assigned to the logical service channel. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9)

10. A method for transmitting vehicle cooperation messages, the method comprising the acts of:
-
receiving from and/or transmitting to a control unit at least one safety-related vehicle cooperation message via a physical channel of a communication unit of a vehicle; administering a logical control channel for receiving and/or transmitting the at least one safety-related vehicle cooperation messages via the physical channel; administering a logical service channel for receiving and/or transmitting at least one non-safety-related vehicle cooperation messages via the physical channel; and assigning the physical channel of the communication unit either to the logical control channel for receiving and/or transmitting the at least one safety-related vehicle cooperation messages or to the logical service channel for receiving and/or transmitting the at least one non-safety-related vehicle cooperation messages, receiving sensor data from one or more sensors of the vehicle, determine a probability of a risk of conflict with another road user in a first time period on the basis of at least one of the received sensor data and received safety-related vehicle cooperation messages; if the determined probability of the risk of conflict is below a predefined threshold value, assign the physical channel, which is otherwise reserved for the logical control channel to exchange safety-related vehicle cooperation messages, by a temporary changeover in the first time period at least partially to the logical service channel; and receive and/or transmit a non-safety-related vehicle cooperation message via the physical channel of the communication unit of the vehicle when the physical channel is assigned to the logical service channel.
