1. A controller for aiding the stability control of a commercial vehicle, the controller comprising:
- one or more inputs for receiving configuration data indicative of a configuration of the vehicle;
one or more inputs for receiving operational data indicative of a stability risk;
a logic applying arrangement for selecting one of a plurality of control tuning modes based on the configuration data received, the logic applying arrangement adapted to determine one or more intervention thresholds based on the selected control tuning mode, wherein the logic applying arrangement compares the operational data to the one or more intervention thresholds and generates a control signal representative of a corrective action as a function of the comparison; and
an output for sending the control signal to an operational system of the vehicle for initiating the corrective action.

Abstract
A system and method for providing stability control for a commercial vehicle. The system may include multiple selectable control tuning modes or sensitivities for defining when the system may intervene to provide corrective action to aid vehicle stability. The control tuning modes may be representative of different vehicle configurations/conditions and a source of input data indicative the present configuration/condition of the vehicle may be provided.

12. A stability control system for a commercial vehicle, the system comprising:
-
a source of input data indicative of a vehicle configuration;
a memory portion for storing two or more selectable sensitivities for the system;
a controller in communication with the source of input data and the memory portion, the controller adapted to receive the input data and select one of the two or more system sensitivities from the memory portion based on the input data; and
a device in communication with the controller for sending operational data to the controller, wherein the controller is adapted to analyze the operational data to determine if a stability risk exists and to send a control signal to an operational system of the vehicle for initiating a corrective action based on the determination. - View Dependent Claims (13, 14, 15, 16, 17, 18)
