Classification: 303/160

Pressure or specific condition (e.g., deceleration) determines wheel speed instead of direct speed sensor:

(under subclass 121) Speed control in which the rate of a road engaging member of a typical vehicle is found by changes in, for example, a compressed fluid system, rate per time change, vehicle rate, displacement, coefficient of friction, to decide braking action.
