The present disclosure relates to a vehicle impact sensor arrangement (25), the vehicle (1) having a forward direction of movement (D). The sensor arrangement (25) comprises a vehicle bumper beam (8) and a vehicle bumper absorbing material (7) with a channel (11), which all have a respective longitudinal extension (L) that mainly extends across the forward direction of movement (D). The sensor arrangement (25) further comprises at least one channel air pressure sensor (12a, 12b). When struck by an object that at least partly compresses the channel (11), it is arranged to confer an air pressure detected by said air pressure sensor (12a, 12b) that first increases from an initial air pressure (P 0 ) to a maximum air pressure (P 1 ), then decreases, falling below the initial air pressure (P 0 ) to a minimum air pressure (P 2 ) before increasing again. This is due to at least one air passage (14, 15, 16, 17) formed between the channel (11) and ambient air. The present disclosure also relates to a corresponding method.
