VEHICLE SYSTEMS AND METHODS FOR DYNAMIC DRIVER TUNING

Vehicles and related systems and methods are provided for assisting operation of a vehicle by enabling dynamic tuning of vehicle responsiveness. One method involves obtaining an auxiliary driver input indicative of an auxiliary driver command to influence responsiveness of the vehicle from an auxiliary human-machine interface device different from a primary human-machine interface device for receiving primary driver input indicative of a driver command to influence a trajectory of the vehicle. In response to the auxiliary driver input, a relationship between a vehicle state command and the driver input is adjusted based on the auxiliary driver input, wherein an actuator control system operates one or more actuators of the vehicle in accordance with the adjusted vehicle state command to influence the trajectory of the vehicle responsive to the primary driver input.
