1. A commercial vehicle comprising:
a cab configured to support an operator of the vehicle;
a chassis;
a semi-active suspension component operably coupling a front portion of the cab to the chassis;
a passive suspension component operably coupling a rear portion of the cab to the chassis;
a first sensor operably coupled to the cab and configured to sense an acceleration of the cab;
a second sensor operably coupled to the chassis and configured to sense an acceleration of the chassis; and
a controller operably connected to the semi-active suspension component and the first and second sensors, wherein the first sensor is configured to provide an input signal to the controller related to the acceleration of the cab, wherein the second sensor is configured to provide an input signal to the controller related to the acceleration of the chassis, and wherein the controller is configured to change a damping characteristic of the semi-active suspension system component based at least in part on the acceleration of the cab and the acceleration of the chassis.
