Abstract
An evaluation computing system may implement techniques to validate a vehicle controller, such as based on an update thereto. The evaluation computing system may access data associated with an operation of the vehicle in an environment as controlled by the controller. The evaluation computing system may modify a portion of the data representative of a fault associated with the controller. The evaluation computing system may run a simulation utilizing modified log data to determine whether the controller detects and/or mitigates the fault within a threshold time. Based on a determination that the controller does not detect and/or mitigate the fault within the threshold time, the evaluation computing system may determine an error associated with the controller. Based on a determination that the controller detects and/or mitigates the fault within the threshold time, the evaluation computing system may validate the controller.
