Assistance system (2) situated in a vehicle V1, which system comprises a position module (4) adapted to determining the vehicle's current location, a map module (6) containing map data and adapted to delivering a map signal (8) comprising information which defines a future horizon with a predetermined length for a future section of road for the vehicle, and a communication module (10) adapted to identifying a vehicle V2 and to establishing a communication link (12) with said vehicle for transmitting and receiving information according to a predetermined communication protocol. The assistance system further comprises an overtaking module (14) comprising a calculation unit (16) and a memory unit (18) and adapted to receiving a first set of vehicle parameters VP1 for the driver's vehicle V1. The communication module (10) is adapted to receiving from vehicle V2 a set of vehicle parameters VP2, and to conveying them to said overtaking module, the overtaking module (14) is adapted to determining that said vehicle V2 is a vehicle ahead, in which case the calculation unit (16) in the overtaking module is adapted to continuously calculating the distance D between the driver's vehicle and the vehicle ahead at one or more predetermined future locations for the driver's vehicle, based on the vehicle parameters VP 1 and VP2, the calculated distances D are stored continuously in said memory unit (18), the calculation unit (16) is further adapted to analysing how D changes, and the overtaking module (14) is adapted to generating overtaking instructions based on the analysis and intended to be presented to the driver of vehicle V1. |
