Abstract: Examples of techniques for classifying roughness of a road are disclosed. In one example implementation, a method includes performing a first temporal analysis based at least in part on a speed of each of a plurality of wheels of a vehicle. The method further includes performing a second temporal analysis based at least in part on a combined wheel speed of the plurality of wheels. The method further includes performing a frequency analysis based at least in part on the speed of each of the plurality of wheels of the vehicle. The method further includes classifying the roughness of the road based at least in part on the first temporal analysis, the second temporal analysis, and the frequency analysis.

Abstract: A system for controlling exhaust noise in a vehicle includes a variable exhaust valve for an exhaust system, and an exhaust valve controller operatively connectable to the variable exhaust valve. The exhaust valve controller is configured to retrieve two or more control conditions, and determine an operational intent based on the two or more control conditions. The exhaust valve controller is configured to generate a control signal based on the operational intent and the two or more control conditions, and transmit the control signal to the variable exhaust valve. The control signal changes an exhaust valve position of the variable exhaust valve. The exhaust valve position is configured to create an exhaust noise response associated with the operational intent.

Abstract: A system comprises a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to receive sensor data including wheel speed measurements, suspension displacement measurements, and tire leak detection data from a vehicle, estimate a rough road measurement based on a deviation of a wheel speed with respect to an average wheel speed and or based on suspension displacement sensor signals and generate temporal spatial map data indicative of a location and a roughness severity metric of a roadway portion based on the rough road measurement and tire leak detection data.

Abstract: A distributed computing system for determining road surface traction capacity for roadways located in a common spatio-temporal zone includes a plurality of vehicles that each include a plurality of sensors and systems that collect and analyze a plurality of parameters related to road surface conditions in the common spatio-temporal zone. The distributed computing system also includes one or more central computers in wireless communication with each of the plurality of vehicles. The one or more central computers execute instructions to determine a road surface traction capacity value for the common spatio-temporal zone.

Abstract: A system comprises a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to receive geoindexed detected vehicle event data from at least one vehicle occurring within a predefined time period, normalize the geoindexed detected vehicle event data according to Global Position System (GPS) data corresponding to a geoindex map, and generate an infrastructure recommendation based on the normalized and aggregated geoindexed detected vehicle event data.

Abstract: Embodiments include methods, systems and computer readable storage medium for a method for detection and notification of a tire leak is disclosed. The method includes receiving, by a tire leak detection system, sensor data from one or more tires. The method further includes determining, by the tire leak detection system, an occurrence of a leak anomaly in at least one of the one or more tires based on the sensor data. The method further includes predicting, by the tire leak detection system, a time and/or distance the at least one of the one or more tires will function ineffectively. The method further includes outputting, by the tire leak detection system, a code to a user or server indicating a leak type associated with the leak anomaly.
