Measurement device for braking reaction time of motor vehicle driver - uses audible or visual signal to start timer and contacts on pedal to stop it, with facility for various start signals

摘要

The reaction time measurement device generates various audible and visual signals and records the driver's reaction time and whether or not driver responded to a predetermined signal and not to other signals. The measurement unit has sets of switches (10,11) to preselect the sequence of signal it will issue. The signals are delivered to a visual transducer and to an audible transducer. The movement of the pedals is monitored by contacts (20,21). The contacts control the operation of the monitoring unit, stopping a counter to record reaction time. The unit has a display (13) that shows the reaction time or produces an alarm signal if the user operated the brakes in error. USE - Instruction aid for person learning to drive vehicle.
