Optimal driving speed control system and method for valuable transport fleet

Abstract

The invention discloses an optimal driving speed control system for a valuable transport fleet and belongs to the technical field of transport fleet speed control. The system comprises a positioning navigation satellite, a plurality of vehicle-mounted satellite positioning modules, a plurality of inter-vehicle data communication modules, a pilot vehicle operation and storage module, a pilot vehicle vibration measurement module, a pilot vehicle image display and voice broadcast unit, a following vehicle operation and storage module, a following vehicle vibration measurement module and a following vehicle image display and voice broadcast unit. According to the invention, a driver of the following vehicle can display the current horizontal driving speed of the following vehicle through the image display and voice broadcast unit; when the following vehicle passes through the concave-convex part of the vertical height level value of the known convex-concave point in front, the allowed maximum running speed and the recommended following speed value of the current following vehicle quickly judge the optimal running speed of the following vehicle where the following vehicle is located, acorresponding voice broadcast prompt is obtained, and the overall average running efficiency of the motorcade is improved.

Description

technical field [0001] The invention belongs to the technical field of speed control of transport fleets, and in particular relates to a system and a method for controlling optimal driving speeds of valuables transport fleets. Background technique [0002] Large-scale valuables are transported in teams of multiple trucks, which have strict requirements on the vibration level of the transported goods during long-distance transportation. Generally, the convoy is required to set the lead vehicle as the leading vehicle, and keep the preset distance between adjacent vehicles. Within the vehicle-to-vehicle distance interval, and the following vehicle cannot exceed the following vehicle vibration threshold preset by human experience, the vibration threshold can be characterized by the instantaneous vertical motion acceleration of the cargo. In actual working conditions, transport vehicles achieve the purpose of vibration reduction by driving slowly and laying shock absorbers on une...

Problems solved by technology

[0008] In order to solve the problem that when the existing convoy transports valuables, it completely relies on the personal experience of the driver of the leading vehicle to judge the road conditions, and uses mobile communication equipment to verbally notify the following vehicles to control the speed of the entire convoy. This old method has large human errors, The timeliness of communication is poor, and the optimal following speed value of the following vehicle cannot be accurately given, which leads to untimely deceleration of the following vehicle and excessive turbulence, which seriously affects the safety of valuables transportation, or causes the entire fleet to fail to meet the premise of safety standards The highest speed per hour increases the burden on the road and restricts the technical problems of transportation efficiency. The present invention provides an optimal driving speed control system and method for valuables transportation fleets.
