Title
(EN) Method and system for modifying a control unit of an autonomous car
Abstract
(EN)

Sensor data is recorded during testing of a control unit of an autonomous car in an autonomous driving mode. In response to being triggered by a disengagement event, recorded sensor data from an analysis time window prior to the disengagement event is logged. The logged sensor data is processed in a simulator using the control unit to control a virtual autonomous car to identify the inadequately operating component of the control unit. The component may be modified and retested until the disengagement event is avoided in the simulator. The control unit with the modified component may then be used to record new sensor data during testing of the control unit in the autonomous driving mode, and the simulation repeated on the new data.
