AI summary

A computer system and computer-implemented method for verifying primary and secondary motion control systems of an automated or semi-automated vehicle are disclosed. A computer system has processing circuitry to send a manoeuvring request to each of the primary motion control system and the secondary motion control system, acquire a first response to the manoeuvring request for the primary motion control system, acquire a second response to the manoeuvring request for the secondary motion control system, and determine if each of the first and second responses are within a threshold of a reference response. The reference response is based on the respective manoeuvring request and/or the other of the acquired first and second responses.
