Abstract: A system has memory that stores instructions executable by the processor to instruct operation of at least one vehicle system (e.g., braking system, propulsion system, steering system, suspension system) in a minimum time mode for travel of the vehicle from a starting point to a destination point of a roadway. The system collects roadway data for the roadway from the starting point to the destination point. Based on the roadway data, the system determine a minimum time path from the starting point to the destination point and speed along the minimum time path. In response to a maximum acceleration input from a human driver of the vehicle when the vehicle is at the starting point, the system initiates the minimum time mode and instructs operation of at least one vehicle system to pursue the minimum time path and speed along the minimum time path from starting point to destination point.

Abstract: A computer is programmed to receive a plurality of first values for a respective plurality of variables transmitted over a communications network of a vehicle; determine a similarity measure between the first values and a plurality of second values of the variables; determine whether to transmit a collection of data transmitted over the communications network based on the similarity measure; and, upon so determining, transmit the collection of data to a server remote from the vehicle. The second values are a most similar set of values from an activation surface for a feature of the vehicle. The activation surface is a surface in a space defined by the variables dividing the space into regions in which activation of the feature is more or less likely than not, respectively, to have occurred when the variables have values in that region.

Abstract: Systems and methods for road disturbance detection and torque vectoring control. A vehicle may comprise: a torque vectoring system for independently varying torque to a plurality of wheels, an external sensor suite, and an electronic control unit. The control unit may comprise one or more processors and memory storing executable instructions that, as a result of execution by the one or more processors, cause the one or more processors to implement an appropriate torque vectoring strategy. The torque vectoring strategy may comprise biasing torque towards or away from a wheel/motor/axle.

Abstract: A first distance is determined between a location of a host vehicle and a received location of a remote vehicle, the remote vehicle being forward of the host vehicle. A second distance is determined between a target vehicle and the host vehicle. A time to reach is predicted between the target vehicle and the remote vehicle based on the first distance and the second distance. A brake of the host vehicle is pre-charged when the predicted time to reach is below a time threshold. Pre-charging of the brake of the host vehicle is suppressed when the predicted time to reach is above the time threshold.
