Abstract

The present invention relates to a hood adjustment assembly comprising a hood (11), first gap sensor (21), second gap sensor (22), hood gap adjuster (12) and hood gap controller (30) comprising processing circuitry (31) configured to- receive a first input signal (SI) from the first gap sensor (21) and a second input signal (S2) from the second gap sensor (22), - determine whether a first criterion for a desired hood gap is fulfilled,- if the first criterion is not fulfilled, determine a desired adjustment of the hood (11),- generate a control signal (C) configured to cause the hood gap adjuster (12) to apply the determined desired adjustment, and wherein the hood gap adjuster (12) is configured to- receive said control signal (C) from the processing circuitry (31), and- move the hood (11) to adjust the hood gap (hg) based on said control signal (C).The invention also relates to a computerized method, a non-transitory computer-readable storage medium and a manufacturing method.
