a wireless communication unit configured to receive external data from an external device; an online receiver configured to: receive vehicle data from one or more devices within the vehicle via one or more first input channels and at least a portion of the external data via the wireless communication unit; and identify a situation requiring braking as online information from the external data and vehicle data received by the online receiver; a first offline receiver configured to: receive at least a portion of the vehicle data from the one or more devices within the vehicle via one or more second input channels; and identify the situation requiring braking as first offline information from the vehicle data received by the first offline receiver; and at least one second offline receiver comprising one or more sensors that are placed such that they can at least record traffic in a direction of travel as traffic data, and wherein the at least one second offline receiver is configured to identify the situation requiring braking as second offline information from the traffic data received by the at least one second offline receiver; and a comparator configured to: compare the online information, the first offline information, and the second offline information; generate a positive or negative result on a basis of the comparison; and transmit the positive result to the brake controller in order to activate the brake controller in response to generating the positive result. ### Claim 2 (depends on 1) The braking system according to claim 1, wherein the comparator is configured to: generate the positive result in response to at least two of the following occurring: the situation requiring braking being identified as the online information in the online receiver, the situation requiring braking being identified as the first offline information in the first offline receiver, and/or the situation requiring braking being identified as the second offline information in the at least one second offline receiver. ### Claim 3 (depends on 1) The braking system according to claim 1, wherein the online receiver is configured to take into account only external data that have a temporal validity when identifying the situation requiring braking as online information. ### Claim 4 (depends on 1) The braking system according to claim 1, wherein the online receiver is configured to take into account only external data that contain a directional vector when identifying the situation requiring braking as online information. ### Claim 5 (depends on 1) The braking system according to claim 1, wherein the one or more devices within the vehicle are connected to the online receiver and to the first offline receiver for an identical transmission of the vehicle data. ### Claim 6 (depends on 1) The braking system according to claim 1, wherein the first input channels and second input channels are separated from one another. ### Claim 7 (depends on 1) The braking system according to claim 1, wherein the comparator is configured to: generate the negative result in response to one or less of the following occurring: the situation requiring braking being identified as online information in the online receiver; the situation requiring braking being identified as the first offline information in the first offline receiver; or the situation requiring braking being identified as the second offline information in the at least one second offline receiver; and issue a warning in response to generating the negative result. ### Claim 8 (depends on 1) The braking system according to claim 1, wherein the wireless communication unit is equipped for vehicle-to-vehicle or vehicle-to-everything communication. ### Claim 9 (depends on 1) The braking system according to claim 1, wherein the one or more sensors for the offline receiver comprise at least one imaging sensor. ### Claim 10 (depends on 1) The braking system according to claim 1, wherein the brake controller is configured to control the actuating drive to control the braking force in response to the positive result. ### Claim 11 (depends on 1) The braking system according to claim 1, further comprising a display placed such that it can be seen by at least a driver, wherein the braking system is configured to show the positive result as information on the display. ### Claim 12 (depends on 1) The braking system according to claim 1, wherein the comparator is configured to: compare and weight differently the online information received from the online receiver, the first offline information received from the first offline receiver, and the second offline information received from the at least one second offline receiver; and generate the positive or negative result on a basis of the weighted comparison. ### Claim 13 (depends on 1) The braking system according to claim 1, further comprising: at least one additional offline receiver configured to identify the situation requiring braking as further offline information and send it to the comparator, wherein the comparator is configured to compare the online information, the first offline information, the second offline information, and the further offline information and generate the positive or negative result on a basis of the comparison. ### Claim 14 (depends on 1) The braking system according to claim 1, wherein the online receiver is configured to evaluate all of the vehicle data and external data it receives itself, wherein the first offline receiver is configured to evaluate all of the vehicle data it receives, and wherein the at least one second offline receiver is configured to evaluate the traffic data. ### Claim 15 (depends on 1) A vehicle comprising the braking system according to claim 1, wherein the vehicle is configured to perform autonomous operation.
