Problems solved by technology

[0004] 1) During the driving process, it is difficult for the driver to drive with the most efficient driving curve in response to complex route conditions, and the operating efficiency is relatively low
[0005] 2) The comfort of passengers depends on the driver's driving behavior. If the driver accelerates and decelerates frequently, brakes too quickly, etc., the comfort of passengers will be affected
[0006] 3) The driver needs to watch the whole process and operate manually, and the workload is relatively large

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0032] Such as figure 1 As shown, based on the automatic driving system of trams that operate autonomously, this system is applied to some long and large sections with good road conditions, including two parts: the on-board system and the trackside Beidou differential base station system. The vehicle-mounted system includes two sets of redundant vehicle-mounted control hosts (including a main-standby switching unit), two route management antennas, two beac...

Abstract

The invention relates to a tramcar automatic driving system based on train autonomous operation. The tramcar automatic driving system comprises a vehicle-mounted subsystem and a trackside Beidou differential base station subsystem which are connected with each other. The vehicle-mounted subsystem comprises a vehicle-mounted control host, a route handling antenna, a beacon reader, an automatic driving host, a Beidou satellite antenna, a Beidou satellite receiver, an obstacle detection laser radar, an obstacle detection camera, a vehicle-mounted signal switch and a vehicle-mounted terminal driver interface. The trackside Beidou differential base station subsystem comprises a Beidou base station antenna, a Beidou positioning base station receiver and a continuous operation reference station system server which are connected in sequence. Compared with the prior art, the system has the advantages that the overall operation efficiency is improved, and the comfort level of passengers is high.

Description

technical field [0001] The invention relates to an automatic driving system for a tram, in particular to an automatic driving system for a tram based on the autonomous operation of a train. Background technique [0002] Modern tram, as a mode of traffic operation with medium traffic volume, has the characteristics of high efficiency, green and environmental protection. Compared with traditional urban rail transit methods, the construction cost of modern tram lines is much lower than that of subway projects. For medium-sized cities, trams are a practical and inexpensive option. [0003] Trams at home and abroad are currently running on open roads. The operating system mainly includes functions such as train positioning, planned local management, auxiliary alarms for speeding and red light violations, on-board automatic / manual processing, and priority application for intersections. The operating environment of trams is complex. During the operation process, the driver’s visu...
