Abstract
A novel wheel slip control device and method improve upon conventional anti-lock brake systems by providing a user interface device which allows the vehicle operator to manipulate the slip ratio threshold of the anti-lock brake system on demand as he or she executes a slide or drift maneuver—thus preventing the system from interrupting the maneuver while also retaining the safety benefits of the anti-lock brake system during ordinary vehicle operation.
Claims12
An apparatus for controlling wheel slip in a vehicle operated by a rider, comprising:
- an anti-lock brake system, wherein the anti-lock brake system controls a braking force on a wheel of the vehicle in relation to a slip ratio of the wheel, such that the anti-lock brake system reduces the braking force if the slip ratio exceeds a threshold;
- and,
- a user interface device operably connected to the anti-lock brake system, the user interface device having an orientation, wherein the orientation of the user interface device is manipulable by the rider within a range of motion, and the anti-lock brake system varies the threshold along a range of values based at least in part on the orientation of the user interface device.
A method for controlling wheel slip in a vehicle operated by a rider and equipped with an anti-lock brake system, comprising:
- setting a slip ratio threshold of the anti-lock brake system to an initial value;
- applying a braking force to a wheel of the vehicle in response to the rider actuating a brake of the vehicle;
- increasing the slip ratio threshold from its initial value in response to the rider manipulating an orientation of a user interface device on the vehicle,
- determining a slip ratio of the wheel;
- and,
- reducing the braking force if the slip ratio exceeds the slip ratio threshold.
An anti-lock brake system controller for a vehicle operated by a rider, comprising:
- a control device configured to control a braking force on a wheel of the vehicle in relation to a slip ratio of the wheel, such that the control device reduces the braking force if the slip ratio exceeds a threshold,
- wherein the control device is further configured to receive a signal from a user interface device operably connected to the control device and having an orientation,
- wherein the orientation of the user interface device is manipulable by the rider within a range of motion,
- and wherein the control device is configured to vary the threshold along a range of values based at least in part on the orientation of the user interface device.
