Embodiment Construction

[0019] The following description is merely exemplary in nature and is not intended to limit the disclosure, its application, or uses.

[0020] According to an exemplary embodiment, figure 1 A vehicle 100 is shown having an active roll control system (ARC system 102 ). The ARC system 102 controls the roll of the vehicle 100 when the vehicle 100 rolls from center to one side or the other, such as when the vehicle 100 is turning. The driver's side sensor 104 a is associated with a driver's side or driver's side tire 106 a of the vehicle 100 . The passenger side sensor 104b is associated with a passenger side or passenger side tire 106b of the vehicle 100 . The driver side sensor 104 a and the passenger side sensor 104 b provide signals that can be used to determine the roll angle of the vehicle 100 . In one embodiment, the driver side sensor 104a and the passenger side sensor 104b are electrical sensors that respectively measure an electrical parameter (eg, current or resistan...

Abstract

A vehicle, and a system and method of controlling the roll of the vehicle are disclosed. The system includes a roll control actuator, a first switch, a second switch and a processor. The first switch is configured to couple the roll control actuator to a first power source. The second switch is configured to control an electrical connection between the roll control actuator and the ground. The processor is configured to operate the first switch to electrically decouple the roll control actuator from the first power source and operate a second switch to the ground to short an ARC motor to the ground to control the roll of the vehicle.

Description

technical field [0001] The subject disclosure relates to an active roll control system for a vehicle, and in particular, to a method of operating an active roll control system during a loss of power from a power source. Background technique [0002] Active roll control systems are systems designed, for example, to reduce vehicle roll in turn, and are typically powered by connecting the system to a high power source, such as a car battery. However, if the high power supply fails or is otherwise disconnected from the active roll control system, the system is allowed to freewheel, which can result in undesired vehicle motion and / or loss of vehicle stability control. Accordingly, it is desirable to provide control of an active roll control system during a loss of power from a high power source. Contents of the invention [0003] In one exemplary embodiment, a method of controlling vehicle roll is disclosed. The roll control actuator is electrically isolated from the first po...
