<p>In order to monitor the operation of two brake pedal switches (A, B), an aspect of vehicle performance which should only occur during braking is detected (20, 22, 23, 24, 26). When this aspect is detected, the status of the brake pedal switches (A, B) is checked for consistency. If at least one of the switches does not indicate that the brake has been applied, cruise control of the vehicle is suspended until repairs have been effected. Such a technique can be applied to transducers other than brake switches and to systems other than vehicles, and allows dormant failures to be detected.</p> |
