Abstract: This invention pertains to an attachment to an electric wheelchair. The attachment enables an electric wheelchair to be used in areas that would not otherwise be possible. An electric wheelchair, though very useful and necessary, has several mobility drawbacks. Off road areas such as beaches, mud, and even tall grass pose a problem to the electric wheelchair. This invention provides an attachment to an existing electric wheelchair and powered off of that wheelchair's motor that allows the user to explore terrain that would not be possible in conventional wheelchair designs. By designing a drive system that works off of the electric wheelchair's power, the attachment can remain purely mechanical. With no motors or electric parts on the attachment, the design is simple and user friendly.

Abstract: A four-wheel drive anti-lock brake control in which the existence of torque transfer between the front and rear wheels of the vehicle is detected based on differences in the duration of ABS control used at each of the independently controlled wheels. Such differences are used to determine a ratio of rear-to-front (or front-to-rear) ABS control. If the ratio indicates the presence of torque transfer, the wheel causing the transfer is identified and its brake pressure released as required to alleviate the detected torque transfer, so long as the release will not cause a change in vehicle deceleration.
