A ground compaction sensing system for a work machine includes a chassis, a ground-engaging mechanism coupled to the chassis, and an attachment movably coupled to the chassis. Multiple sensors are configured to generate a chassis angle signal, an attachment angle signal, an attachment spacing signal, and a location signal. The controller has a non-transitory computer readable medium with a program instruction to grade a surface. The program instructions when executed cause a processor of the controller to receive the aforementioned signals and determine an as-built grade of the surface based on an attachment reference point at a first location of the location signal; and a compaction value when a chassis reference point reaches the first location as the work machine traverses across the surface. The program instructions may then include modifying movement of the attachment based on the compaction value.

Ground compaction sensing system and method for a work machine

A work vehicle may include a chassis, a ground-engaging blade, a first sensor, a second sensor, and a controller. The blade may be movably connected to the chassis via a linkage assembly configured to allow the blade to be raised and lowered and moved in a roll direction. The first sensor may be configured to provide a chassis inclination signal indicative of a main fall angle, a chassis roll signal indicative of a cross slope angle, and a chassis heading signal. The second sensor may be configured to provide a blade inclination signal and a blade roll signal. The controller may be configured to receive the signals, determine a target grade, determine a distance error based on the signals indicative of a distance between the blade and the target grade, and send a command to move the blade toward the target grade based on the distance error.
