1. In a sensor for responding to the rate of change of changing rotational speeds of a vehicle wheel and including a flyweight coupleable for rotation in response to wheel rotation and selectively decoupleable in response to the exertion on the flyweight of a torque having a magnitude greater than a threshold magnitude due to a change in rotational speed of the wheel, control means operatively connected with the flyweight for exerting on the flyweight torques resisting decoupled rotation of the flyweight, and signalling means operatively connected with the control means and responsive to decoupled rotation of the flyweight for signalling occurrences of an excessive rate of change in changing rotational speeds of the wheel, an improvement in said control means comprising means for exerting on said flyweight an average of a plurality of resistive torques.
