Abstract: A control computer includes a computer memory and a computer processor programmed to execute instructions stored in the memory to perform a lidar calibration test. The instructions include collecting texture data output by a lidar sensor, the texture data representing a detected texture of an interior surface of a first jig disposed about the lidar sensor, comparing the texture data output by the lidar sensor to a known texture of the interior surface of the first jig, determining that the lidar sensor needs to be calibrated as a result of comparing the texture data to the known texture, and calibrating the lidar sensor by uploading updated values for use with the lidar sensor.

Abstract: A computer includes a processor and a memory storing instructions executable by the processor to determine at least one of a vehicle pitch or a longitudinal center of gravity from data measured while deactivating a first brake for a first axle and applying a second brake for a second axle, and operate the vehicle based on the at least one of vehicle pitch or longitudinal center of gravity. The instructions may further include to determine a vehicle weight from the data, and operate the vehicle based on the vehicle weight.

Abstract: A vehicle computer includes a memory and a processor programmed to execute instructions stored in the memory. The instructions include receiving a first minimum risk condition (MRC) event recommendation from a first platform controller and a second MRC event recommendation from a second platform controller, selecting one of the first and second MRC event recommendations as a selected MRC event, controlling an autonomous host vehicle according to the selected MRC event.
