A method of controlling travel of a vehicle equipped with an antilock braking system, including the steps of determining potential for one or more wheels to lift off the ground, deactivating the system in respect of the wheels with the lift off potential so the speed of these wheels is not taken into consideration when determining if anti-lock braking is required, applying a low-level test braking force to one or more of the wheels that has the lift off potential, monitoring the speed of the one or more wheels, and if the test braking force causes the wheel speed to fall below a predetermined percentage of the vehicle speed, triggering a stability alarm signal and/or applying a controlled braking force to reduce the vehicle speed.

Vehicle stability control method

A control system for electronically controlled vehicle dynamics control systems and ride control systems includes a system ECU and a diagnostics ECU, each having a memory with vehicle parameters stored thereon. When one of the system ECU and the diagnostics ECU is replaced, the other one communicates via a communications link the vehicle parameters stored in the memory thereof to the replaced one of the system ECU and the diagnostics ECU. The vehicle parameters stored on at least one of the system ECU and the diagnostics ECU are user modifiable, and when the vehicle parameters stored on one of the system ECU and the diagnostics ECU are modified by a user, the one of the system ECU and the diagnostics ECU on which the vehicle parameters were modified communicates via the communications link the modified vehicle parameters to the other one.
