Abstract

A device and a method for transmitting an activation decision for an actuator system from a first to at least one second control unit is provided, the second control unit activating the actuator system as a function of at least two messages from the first control unit.

Claims

1. A method for transmitting an activation decision, the method comprising:

transmitting an activation decision for an actuator system from a first control unit to at least one second control unit, wherein the activation decision is made in the first control unit and is comprised of at least two messages; and

activating the actuator system as a function of the at least two messages that includes the activation decision from the first control unit, wherein the second control unit is set to an active state by the first message and the second message brings about the activation of the actuator system if the second control unit has been set to the active state.

2. The method of claim 1, wherein the first and the second control unit respectively activate different actuator systems.

3. The method of claim 1, wherein the activation takes place when the second control unit receives at least two messages, the second message having been generated by a third message from the second control unit to the first control unit.

4. The method of claim 1, wherein the first and the second control unit respectively activate different actuator systems, wherein the second control unit is set to an active state by the first message and the second message brings about the activation of the actuator system if the second control unit has been set to the active state, and wherein the activation takes place when the second control unit receives at least two messages, the second message having been generated by a third message from the second control unit to the first control unit.

5. A method for transmitting an activation decision, the method comprising:

transmitting an activation decision for an actuator system from a first control unit to at least one second control unit; and

activating the actuator system as a function of at least two messages from the first control unit;

wherein the first control unit activates a personal protective arrangement and the second control unit activates at least one of an electronic stability program and a brake system.

6. A first control unit for a vehicle, comprising:

a first evaluation circuit to generate an activation decision as a function of a sensor signal, wherein the activation decision is made in the first control unit and is comprised of at least two messages; and

a transmitting arrangement to transmit the at least two messages that includes the activation decision via a first interface for the activation decision, wherein the first control unit is set to an active state by the first message and the second message brings about the activation of the actuator system if the first control unit has been set to the active state.

7. The first control unit of claim 6, wherein the activation decision is used to activate a personal protective arrangement.

8. A control unit system for a vehicle, comprising:

a first control unit;

a first evaluation circuit to generate an activation decision as a function of a sensor signal, wherein the activation decision is made in the first control unit and is comprised of at least two messages;

a transmitting arrangement to transmit the at least two messages that includes the activation decision via a first interface for the activation decision;

a second control unit; and

a second evaluation circuit that activates an actuator system as a function of two messages that are provided by a second interface, wherein the second control unit is set to an active state by the first message and the second message brings about the activation of the actuator system if the second control unit has been set to the active state.

9. The second control unit of claim 8, wherein the second control unit is configured to activate at least one of an electronic stability program and a brake assist system.

10. A device for transmitting an activation decision, comprising:

a transmitting arrangement to transmit an activation decision for an actuator system from a first control unit to a second control unit, wherein the activation decision is made in the first control unit and is comprised of at least two messages, the second control unit activating the actuator system as a function of the at least two messages that includes the activation decision from the first control unit, wherein the second control unit is set to an active state by the first message and the second message brings about the activation of the actuator system if the second control unit has been set to the active state.

11. The device of claim 10, wherein the first control unit and the second control unit respectively control different vehicle systems.

12. A device for transmitting an activation decision, comprising:

a transmitting arrangement to transmit an activation decision for an actuator system from a first control unit to a second control unit, the second control unit activating the actuator system as a function of at least two messages from the first control unit;

wherein the first control unit is configured for activating a personal protective arrangement and the second control unit for activating at least one of an electronic stability program and a brake assist system.

13. A method for transmitting an activation decision, the method comprising:

transmitting an activation decision for an actuator system from a first control unit to at least one second control unit; and

activating the actuator system as a function of at least two messages from the first control unit;

wherein the first control unit activates a personal protective arrangement and the second control unit activates at least one of an electronic stability program and a brake system, wherein the second control unit is set to an active state by the first message and the second message brings about the activation of the actuator system if the second control unit has been set to the active state, and wherein the activation takes place when the second control unit receives at least two messages, the second message having been generated by a third message from the second control unit to the first control unit.
