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: Method and apparatus are disclosed for monitoring and adjustment of gaps between vehicles. An example vehicle includes a rear sensing device and a controller. The controller is to determine a target lead gap for following a lead vehicle during adaptive cruise control and measure, via the rear sensing device, a trailing distance to a trailing vehicle. The controller also is to determine a target trailing gap for the trailing vehicle. The example vehicle also includes a cruise control unit to increase, responsive to the trailing distance being less than the target trailing gap, the target lead gap based on the trailing distance.
