Methods and apparatus for adjusting a suspension of a vehicle are described herein. An example apparatus includes a memory storing a plurality of suspension profiles. Each of the suspension profiles includes a stored performance parameter of a vehicle and a suspension setting. The apparatus includes a sensor to detect a driver performance parameter of a driver driving the vehicle. The driver performance parameter represents a behaviour of the driver of the vehicle. The apparatus further includes a processor to compare the driver performance parameter to at least one of the plurality of suspension profiles stored in the memory, and a controller to adjust a suspension of the vehicle according to a first suspension setting of a first suspension profile of the plurality of suspension profiles if the driver performance parameter corresponds to a first stored performance parameter of the first suspension profile.

Methods are provided for proactively controlling a component of a system. The system may comprise a vehicle and the component may comprise a suspension of the vehicle. According to various aspects, methods may include obtaining information regarding a travel surface along a travel path that the system will travel at a future time and, based on the information regarding the travel surface, controlling the component of the system to traverse the travel surface. Controlling the component based on the information regarding the travel surface may comprise comparing the information regarding the travel surface to information regarding at least one physical constraint of the system and/or comparing frequency content of the information regarding the travel surface to a threshold frequency. Proactive control methods may provide improved response to disturbances and improved tracking and isolation because a suspension may be controlled with reduced or substantially zero delay.

An agricultural work machine includes a geographic position sensor that detects a geographic location of the agricultural work machine. An in-situ sensor detects a value of a dynamic response characteristic of the agricultural work machine corresponding to the geographic location. A predictive model generator generates a predictive model that models a relationship between the terrain feature characteristic and the dynamic response characteristic based on a value of the terrain feature characteristic in a prior information map at the geographic location and a value of the dynamic response characteristic sensed by the in-situ sensor at the geographic location. A predictive map generator generates a functional predictive dynamic response map of the field, that maps predictive values of the dynamic response characteristic to the different geographic locations in the field, based on the values of the terrain feature characteristic in the prior information map and based on the predictive model.
