SAFETY OPERATION LIMITER

ABSTRACT

PROPOSED SOLUTION TO THE PROBLEM

  Complex features of electronic equipment in a vehicle are disabled while the vehicle is moving. This reduces distraction of the driver and therefore enhances traffic safety.

  The solution described here reduces the number of control functions of an in-vehicle communica- tions device to a minimum while the vehicle is mov- ing. Use of the equipment may even be disabled completely.

   Firstly, a sensor detects the movement of the vehicle and generates a signal. This signal is fed into the device that is to be controlled. As soon as the vehicle starts moving, the device sets all keys, knobs, buttons, switches etc. to a default function or disables them completely.

  At this time, the driver cannot any longer enter functions that need significant attention, Softkeys, those keys with varying functionality which depend on previous actions, get fixed pre-defined functions assigned to them. These functions are such that the driver does not need to watch the display to decide and check his inputs.

  The display may be arranged to show only the most relevant or basic data to reduce the risk of dis- tracting the driver. For example, a 2-way radio may allow only changes to the volume and the squelch while moving. The changing of IDS or frequencies would be disabled. The display may show only the channel number.

  If the vehicle comes to a stop, the complete functionality of the keys, switches, control buttons etc. is then resumed. The display would then show more advanced information again. The driver could then once more make use of all the features and functions of the device.

INTRODUCTION

  This paper describes a way of reducing the safety risks of operating a vehicle and using telecommunications equipment simultaneously. The number of control options available in the equip- ment is limited while the vehicle is in motion. PROBLEM TO BE SOLVED

  Cars, trucks, buses and other vehicles are often equipped with communications devices which have complicated and complex control options. The oper- ator has to monitor the devices' optical and acoustic outputs. Keys may have different functions depend- ing on previous key pres...
