Vehicle zone-crossing control method, device and system

Abstract

The invention provides a vehicle zone-crossing control method, device and system and used for overcoming one or more defects that in the prior art, it is difficult to guarantee consistency and compliance of vehicle electricity receiving / vehicle sensing before and after zone crossing. The vehicle zone-crossing control method includes the steps that after a first vehicle enters a control cross connecting zone, a first road segment sends vehicle information of the first vehicle to a third road segment which is adjacent to the first road segment and to which the first vehicle drives; or, after the first vehicle enters the control cross connecting zone, the first road segment continues sensing and control over the first vehicle till the first vehicle drives out of the control cross connecting zone; the vehicle information is used by the road segment to which the vehicle drives, and a sensor element group is selected from a sensor element array arranged in the road surface zone or a road side zone for positioning the vehicle; or the road segment to which the vehicle drives uses the sensor element array which is arranged in the road surface zone or the road side zone and located in a length range of the control cross connecting zone for conducting one or more operation of obtaining the vehicle position information, obtaining the vehicle information or conducting driving control on the first vehicle driving into the control cross connecting zone. By means of the method and device, rapid transmission of vehicle information between road segments can be achieved, consistency and compliance of vehicle electricity receiving / vehicle sensing before and after zone crossing can be achieved, and practicability is achieved.

Description

technical field [0001] The present invention relates to the field of transportation, in particular to a method, device and system for vehicle overrun control. Background technique [0002] The future road integrates electrification and intelligence, and is a comprehensive platform that provides driving channels, driving power and driving control for vehicles. [0003] Considering the convenience of technical realization, it is a common power supply method in subways and high-speed rails to divide a road of several hundred kilometers into several shorter road sections and provide power supply in units of road sections. In the future, electrified roads and / Or in the construction of intelligent roads, it is also practical to use segmented power supply, segmented control, and segmented management. In the case where power supply, control, and perception are implemented in segments, the vehicle must cross the road section when it is running on the road. In the process of the ve...

Problems solved by technology

[0012] The existing APS (Advanced Power Supply: Advanced Power Supply System) system and Italy's Tramwave ground power supply system also supply power to vehicles traveling along fixed tracks, and do not involve accurate perception of the vehicle's driving posture, as long as the power is supplied on the road A sensor that can sense the position of the vehicle's power receiving shoe is arranged on the rail, and it is enough to use the induction signal to trigger the power supply rail to turn on the power. This sensing method cannot realize the trigger power supply for the driving posture / trajectory of the road trackless vehicle. The section controller of the road section needs to know the authentication result before supplying power to the vehicle from the previous section. If the authentication result is obtained, it is not given in the existing ground rail vehicle power supply technology. Therefore, the power receiving vehicle’s It is difficult to determine the identity, and it is difficult to guarantee the compliance of power receiving, because if the authorization of the vehicle is not reviewed on the new road section after the handover, some vehicles will be connected to the power supply network without authentication at the road section handover

[0013] Although the existing patented technology provides a method for guiding the receiver to be connected during the connection process, it does not provide information about the vehicle's identity and driving posture during the vehicle's driving process, especially during the vehicle's crossing process. The method of perception, etc., does not give the method of how to maintain the continuity of power supply and obtain authentication information during the handover process

[0014] Existing cross-area power supply technology is difficult to guarantee the continuity and compliance of road trackless vehicles before and after cross-area vehicle power reception / vehicle perception
