Abstract: A set of first candidate topologies of first candidate roadside infrastructure nodes at respective mounting locations in a geographic area is randomly generated. For each of the first candidate topologies, first simulations, including detection of objects according to selected sensor parameters, installation parameters, and environment parameters for the candidate nodes at the respective mounting locations, are executed. First fitness scores are determined for each of the first candidate topologies by comparing results of the first simulations to ground truth data. Upon identifying one of the first fitness scores as exceeding a threshold, the candidate topology associated with the identified first fitness score is identified for deployment.

Abstract: A computer can execute instructions to collect vehicle sensor data from sensors on a vehicle. Based on a determination that the vehicle is within a threshold distance of a road infrastructure geofence indicating a presence of a target road infrastructure element, the instructions further include to identify selected data from the vehicle sensor data; and transmit the selected data to a remote server.

Abstract: An infrastructure system includes at least one sensor, a transceiver, and a computer communicatively coupled to the at least one sensor and to the transceiver. The computer is programmed to receive data from the at least one sensor indicating respective locations and motions of objects in an environment surrounding the at least one sensor; in response to one of (a) the data from the at least one sensor or (b) a request from a user, generate a virtual traffic marker at a first location in the environment; and instruct the transceiver to broadcast the virtual traffic marker to vehicles in the environment. The first location is based on the data from the at least one sensor, and the virtual traffic marker is data including the first location and traffic instructions corresponding to the first location.

Abstract: A system includes a shaft extendable from a vehicle roof, a sensor mount mounted to the shaft, a plurality of sensors supported by the sensor mount, and a computer communicatively coupled with one or more of the sensors to receive data from the one or more of the sensors, the computer including a processor and a memory. The memory stores instructions executable by the processor to extend the shaft to position the sensor mount to a specified height above the roof.

Abstract: An engine of a stop/start vehicle, after the engine has been automatically stopped, may be commanded to automatically restart in response to detecting that the vehicle is in a turn lane based on traffic data in a vicinity of the vehicle such that the engine is automatically restarted before a brake pedal is released and a steering wheel is turned.

Abstract: Methods and systems are provided for improving vehicle torque control accuracy. Data points of an engine torque data set are adjusted en masse by an on-board vehicle controller while also being adjusted individually by an off-board controller. By adjusting engine operation based on a torque data set that is updated by each of the on-board and off-board controllers, engine torque errors can be reliably determined and compensated for.

Abstract: A stop/start vehicle includes an engine and a stop/start system that prevents an auto stop of the engine when a speed of the vehicle is approximately zero in response to the vehicle being located within a specified distance from a body of water or in response to the vehicle being located in a user identified geographic region.

Abstract: A stop/start vehicle includes an engine and a stop/start system that prevents an auto stop of the engine when the speed of the vehicle is approximately zero in response to the vehicle being located at a service location or in response to the vehicle being located in a user identified geographic region.

Abstract: A controller in a stop/start vehicle may anticipate a vehicle stop and engine shutdown event in response to detecting a vehicle approach to an intersection. The controller may disable a power steering system or otherwise prepare vehicle subsystems for shutdown prior to the anticipated shutdown event. The controller may also enable the power steering system in response to anticipating an automatic restart event.
