Abstract

A vehicle dispatching system for controlling dispatching communications between vehicles and a control center mainly includes a control center and at least one vehicle. Every vehicle has equipped with a car phone. The control center includes a control computer and a data transmission device. The car phone consists of a broadcast receiver, a data transceiver, a GPS receiver, and a distance counter. By means of the system of the invention, the available vehicle nearest customers may be dispatched to meet customer service requirements at minimum communication costs.

Claims

1. A vehicle dispatching system comprising a control center which based on customer requesting services controls dispatching communication to at least one vehicle which equipped with a car phone, wherein:

the control center includes at least a control computer and a data transmission device, the control computer having software resided therein to perform mission information coding and display information, current mission schedules, and performing status of dispatched vehicles, the data transmission device being allowed to couple with an existing broadcast system including GSM handsets and paging services established by telecommunication companies;

the car phone includes;

a broadcast receiver for receiving broadcast information from the control center;

a data communication device for transmitting and receiving data and information;

a GPS receiver for receiving positioning signals emitting from positioning satellites stationed on earth obits; and

a distance (time) counter for calculating relative distance between vehicle location and a mission location.

2. The vehicle dispatching system of claim 1, wherein the car phone is coupled with a handfree handset device which includes a handfree handset which has a microphone and a speaker for entering voice speech or delivering voice speech output to perform conversation operations for the handfree handset.

3. The vehicle dispatching system of claim 1, wherein the car phone includes an audio module for outputting broadcasting signals in voice speech fashion.

4. The vehicle dispatching system of claim 1, wherein the car phone has a control key for stopping return call or transmitting verbal messages to the control center to reject dispatching commands.
