Integrated Vehicle Dispatching and Navigation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current taxi dispatching methods in busy cities are inefficient and inconvenient for drivers, requiring manual operation of navigating devices while driving and lacking integration with dispatching systems.
Innovation Solution
A vehicle-dispatching method and system that uses a service center to communicate with vehicles equipped with a navigating device, allowing for automatic route calculation and navigation from the vehicle's current position to the passenger's location, minimizing manual operations for drivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual navigation operation is required for taxi drivers, then navigation functionality can be provided, but driver workload increases and safety decreases
Solution Approach 1:
The patent combines the dispatching system and navigation system into an integrated vehicle-mounted device. The dispatching module receives task information from the service center, and the navigation module automatically generates routes based on this information, merging two previously separate functions into one unified system that eliminates manual operations.
Solution Approach 2:
The system enables automatic route generation and navigation by the vehicle-mounted device itself. When the dispatching module receives task information, the navigation module automatically calculates the route from current position to destination without requiring driver intervention, allowing the system to serve itself.
2Adaptability or versatility
If separate dispatching and navigation systems are used, then system functionality is comprehensive, but system complexity increases
Solution Approach 1:
The patent integrates the dispatching module and navigation module into a single vehicle-mounted device with shared hardware resources (processor, memory, display, GPS receiver). This merging reduces system complexity while maintaining comprehensive functionality through modular software design.
Solution Approach 2:
The vehicle-mounted device is designed as a multi-functional universal platform that can perform both dispatching operations (receiving tasks, communicating with service center) and navigation operations (route calculation, guidance display). This universal design reduces the need for separate specialized devices.
3Extent of automation
If automatic route generation is implemented, then driver workload is reduced, but system automation complexity increases
Solution Approach 1:
The navigation module automatically generates routes by receiving task information from the dispatching module and independently calculating the optimal path from current position to destination. This self-service automation reduces driver workload while keeping the automation logic contained within the navigation module itself.
Solution Approach 2:
The system performs preliminary route calculation automatically as soon as task information is received, before the driver needs to navigate. The route is pre-computed based on current position and destination, ready for immediate navigation without requiring complex real-time decision-making during driving.

AI summary
A vehicle-dispatching system includes a service center and a plurality of hosts disposed in respective vehicles, and one of the vehicles is selected for dispatching when the service center receives a vehicle request from a passenger. For facilitating drivers to decide whether to accept the task, a message including location information of the passenger is sent to dispatching units of the hosts by the service center to trigger navigating units of the hosts to reveal respective route information for the drivers' reference. Once one or more drivers decide to accept the task, they may trigger the dispatching units to issue respective task-accepting signals to the service center. The service driver then selects one of the vehicles for dispatching by sending a dispatching signal to the dispatching unit of the selected vehicle. The dispatching signal then triggers the navigating unit of the selected vehicle to automatically reveal navigating information.
