Abstract
Methods are provided for supervising a motor control unit with at least two separate channels, each of the two channels including at least: means for executing a given application task AS, the application task AS including a plurality of successively executed computations between which latency periods elapse; a first component capable of performing the computations; a second component capable of storing data; the application tasks AS of the channels being capable of communicating. The method includes the following steps: a) detecting a latency period; b) performing, during this latency period, an operating state test of at least one of the components; and c) determining a state of the component corresponding to a failure state or a healthy state.
