1. A method of controlling travel of a vehicle equipped with an antilock braking system, the method comprising the steps of:

  • determining a potential for one or more wheels of the vehicle to lift off the ground;

    deactivating the anti-lock braking system in respect of the wheels with the potential to lift off the ground so that the speed of these wheels is not taken into consideration when determining to apply anti-lock braking control;

    applying a low-level test braking force to the wheels with the potential to lift off the ground;

    monitoring the speed of the wheels with the potential to lift off the ground;

    triggering a stability alarm signal and/or initiating a control intervention to reduce the vehicle speed when the test braking force causes the speed of the wheels with the potential to lift off the ground falls below a predetermined percentage of the vehicle speed; and

    increasing the braking force applied to the wheels without potential to lift off the ground by a greater amount than the braking force applied to the wheels with potential to lift off the ground when it is determined that there is potential for one or more of the wheels to lift off the ground during braking following braking demand from a driver of the vehicle, or when the driver issues a demand for braking during a braking test pulse, where the braking demand requires a braking force which is below a predetermined level.
