A vehicle has an engine (10) which drives wheels (16,24) of the vehicle via a CVT (11). The vehicle also has a driver operated braking system which brakes wheels of the vehicle, and an electronic control system (28,60) which, in the event of deceleration of the vehicle, detects when the driven wheels are about to lock and increases the currently operative CVT ratio to allow the locking wheels to speed up towards a rotational speed corresponding with the current vehicle speed whilst ensuring that any braking operation selected by the driver is maintained subject to the avoidance of wheel locking. The CVT is of the hydrostatic/mechanical power split type and the braking system includes an anti-lock braking (ABS) function which can provide the wheel speed and vehicle speed values and prevent wheel locking under braking.
