The position data can be processed further within the update device in order to allow accurate and prompt updating of a subregion of the map without this requiring communication with the map manufacturer or service provider. ## Claims ### Claim 1 An update device of a first vehicle for generating and updating a digital map for the first vehicle, said update device of the first vehicle comprising: a communication unit for receiving update data from a second vehicle, the update data including position information of the second vehicle and roadway information detected by a driving dynamic system of the second vehicle; and an update unit for generating or updating the roadway for the first vehicle on a basis of the update data, wherein the driving dynamic system includes at least one of an anti-lock brake system (ABS), a Traction Control System (TCS), an Electronic Stability Program (ESP) and an Electronic Differential Lock (EDL). ### Claim 2 (depends on 1) The update device as claimed in claim 1, wherein the second vehicle is situated in surroundings of the first vehicle, so that the update data relate to a portion of the digital map which is located in the surroundings of the first vehicle. ### Claim 3 (depends on 1) The update device as claimed in claim 1, wherein the update device has an input device which a driver can use to determine which portion of the digital map needs to be updated. ### Claim 4 (depends on 1) The update device as claimed in claim 1 further comprising: a capture unit for capturing a measured value for a position of the first vehicle; wherein the communication unit is configured to transmit second update data, which is based on captured measured value, to the second vehicle. ### Claim 5 (depends on 1) The update device as claimed in claim 1, wherein the first update data are transmitted directly from the second vehicle or from a control center to the first vehicle. ### Claim 6 (depends on 1) The update device as claimed in claim 1, wherein the update device is configured to statistically evaluate all received update data. ### Claim 7 (depends on 1) The update device as claimed in claim 1 further comprising: a memory device for storing an update for the digital map. ### Claim 8 (depends on 1) The update device as claimed in claim 1 further comprising: a warning device to warn a driver of hazards which have been identified on a basis of the update data. ### Claim 9 (depends on 1) The update device as claimed in claim 1, wherein the digital map is a digital navigation map. ### Claim 10 (depends on 1) An update system for generating and updating a digital map for a first vehicle, said update system comprising: a first and second update device as claimed in claim 1 in a first vehicle; and a control center for receiving update data from the first vehicle and for transmitting the update data to the second vehicle. ### Claim 11 (depends on 1) The use of an update device as claimed in claim 1 in a vehicle. ### Claim 12 A method for generating and updating a digital map for a first vehicle, said method comprising the following steps: receiving update data in the first vehicle from a second vehicle, the update data including position information of the second vehicle and roadway information detected by a driving dynamic system of the second vehicle; and generating or updating the roadway for the first vehicle on a basis of the update data, wherein the driving dynamic system includes at least one of an anti-lock brake system (ABS), a Traction Control System (TCS), an Electronic Stability Program (ESP) and an Electronic Differential Lock (EDL). ### Claim 13 A computer program product which, when executed on a processor, instructs the processor to perform the following steps: receive update data in a first vehicle from a second vehicle, the update data including position information of the second vehicle and roadway information detected by a driving dynamic system of the second vehicle; and generate or update the roadway for the first vehicle on a basis of the update data, wherein the driving dynamic system includes at least one of an anti-lock brake system (ABS), a Traction Control System (TCS), an Electronic Stability Program (ESP) and an Electronic Differential Lock (EDL). ### Claim 14 A non-transitory computer-readable medium which stores a computer program product which, when executed on a processor, instructs the processor to perform the following steps: receive update data in a first vehicle from a second vehicle, the update data including position information of the second vehicle and roadway information detected by a driving dynamic system of the second vehicle; and generate or update the roadway for the first vehicle on a basis of the update data, wherein the driving dynamic system includes at least one of an anti-lock brake system (ABS), a Traction Control System (TCS), an Electronic Stability Program (ESP) and an Electronic Differential Lock (EDL).
