Abstract: A computer includes a processor and a memory, and the memory stores instructions executable by the processor to receive a set of points indicating a lane boundary; select a first subset of the points, wherein the set of points includes a first point that is not in the first subset; determine a path of the lane boundary based on the first subset of the points; and, upon determining that the first point is greater than a threshold distance from the path, add the first point to the first subset.

Abstract: Based on a set of planned control parameters defining a planned path for a vehicle, a set of reference control parameters corresponding to the set of planned path control parameters are identified. Optimized controller inputs associated with the identified set of reference control parameters, the set of planned control parameters, and operation noise data are input to a vehicle dynamics model that outputs a vehicle state model. Based on the vehicle state model, an actual path for the vehicle and an operating range for the actual path are determined. The planned path is determined to be one of verified or unverified based on the operating range.

Abstract: A power system for a vehicle includes a control module, a low-voltage battery electrically coupled to the control module, a high-voltage battery electrically coupled to the control module, an engine electrically coupled to the high-voltage battery, and a computer. The computer is programmed to, while the vehicle is in an off state, in response to a pending download to the control module, provide power to the control module with one of the low-voltage battery, the high-voltage battery, or the engine upon determining whether the low-voltage battery and the high-voltage battery have sufficient charge to power the control module for the download.

Abstract: A system includes a virtual-driver module, a DC/DC converter electrically coupled to the virtual-driver module, a low-voltage battery electrically coupled to the virtual-driver module, a high-voltage battery electrically coupled to the DC/DC converter, and a computer communicatively coupled to the DC/DC converter. The computer is programmed to, in response to a request to start a vehicle including the virtual-driver module in a manual mode, the vehicle being in an off state at the time of the request, set a setpoint of the DC/DC converter at a first voltage; then perform at least one pre-drive test on the vehicle; and then set the setpoint of the DC/DC converter at a second voltage lower than the first voltage.

Abstract: A computer includes a processor and a memory, the memory storing instructions executable by the processor to receive a request to activate a vehicle, receive diagnostic data for one or more vehicle components from an activation component, arbitrate the request and the diagnostic data to identify an activation mode of the vehicle that is one of an unpowered mode, a power-up mode, or a fully-started mode, and instruct the activation component to activate one or more vehicle components associated with the identified activation mode.
