Embodiment Construction

[0038] Embodiments of the present invention provide a fleet maintenance method, which can effectively maintain the clustering degree of vehicles.

[0039] Embodiments of the present invention provide an on-vehicle information system capable of timely providing suggested driving speeds of vehicles so as to keep the vehicles in the fleet.

[0040] The fleet maintenance method according to this exemplary embodiment is to enable vehicles in the same fleet to exchange information (for example, the position coordinates and driving speed of each vehicle) with each other through a stable and low-cost connection method, and through this information The degree to which each vehicle should be accelerated and decelerated can be judged. That is to say, through these information exchanges, the system can remind the driver to accelerate appropriately when the vehicle is behind the entire convoy, and the system can remind the driver to slow down appropriately when the vehicle is too far ahead...

Abstract

The invention relates to a motorcade maintaining method and a vehicle-mounted communication system. In the motorcade maintaining method, the suggested advance vehicle speed of each vehicle is provided by utilizing the exchange and dispersion type algorithm of a vehicle position and vehicle speed information to maintain the degree of motorcade clustering. The method comprises the following steps of: grouping vehicles into a plurality of sub-motorcades and recognizing conducting vehicles and member vehicles in the sub-motorcades; obtaining position coordinates and advance vehicle speed of each vehicle in each sub-motorcade and converting the position coordinates of each vehicle into corresponding one-dimensional coordinates; calculating a sub-motorcade gravity center of each sub-motorcade and a motorcade gravity center of the whole motorcade according to the converted one-dimensional coordinates; and generating the suggested advance vehicle speed of all the conducting vehicles accordingto the gravity center distances of all the conducting vehicles and accordingly generating the suggested advance vehicle speed of all the member vehicles.

Description

technical field [0001] The invention relates to a fleet maintenance method and a vehicle communication system. Background technique [0002] With the advancement of science and technology and the development of transportation means, the mobile demand of modern people has greatly increased, so users are quite eager for an information system that can provide destination guidance or map guidance. Due to the popularization of personal mobile devices and the commercialization of the Global Position System (GPS), GPS guidance devices have emerged. [0003] Current portable electronic devices can be combined with GPS technology for navigation and positioning purposes, mainly used for navigation and positioning of vehicles, ships, and airplanes, and the above-mentioned portable electronic devices are, for example, built-in or external GPS antennas Portable electronic devices such as modular mobile phones, personal digital assistants or navigators. Today, with the increasing popula...
