<p>A method and apparatus for use in a driver trainer simulator of the type wherein a clutch pedal is provided for operation by the student under simulated driving conditions. In the embodiment described below, the clutch pedal is mechanically linked to a plurality of switches which each sequentially connect to a number of associated contacts as the pedal is pressed and released. One of these contacts is associated with the point at which the clutch pedal would be engaged in a conventional vehicle and when the switch is connected to this contact an associated capacitor is charged through a resistive network. The next contact encountered by the switch as the now engaged clutch pedal is further released connects the charged capacitor across a relay coil so that the relay remains activated only if the rate at which the clutch pedal was released through the friction point was slow enough for the capacitor to charge to a given level. Thus deactivation of the relay coil represents a popped clutch and causes controlled switches to produce an indication on the simulator that a stall condition has been produced.</p> |
