Abstract

The invention relates to an engine control device comprising a first control channel (V1) and a second control channel (V2), each control channel comprising a first sensor (CAV1, CAV2) and a second sensor (CBV2, CBV2), each configured to provide, respectively, a first measurement (A) and a second measurement (B) to each channel, each of the channels having an active or passive state defining an active channel (V1) or a passive channel (V2), the active channel (V1) being designed to control at least one actuator (ACT) of the engine while the passive channel (V2) is designed to take over for the active channel if the latter fails.
