Problems solved by technology

However, how to use the control-by-wire all-axis technology to realize the controllable wheel trajectory of the rubber-tired train, and even ensure the trajectory overlap rate of the wheels in the forward direction, so as to increase the trajectory overlap rate between the rear wheel and the front wheel in the forward direction and reduce the steering " Inner wheel difference" and reducing the "blind sight angle" are technical problems that have not been well resolved.

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 and figure 2 Shown, the control system of virtual track vehicle train of the present invention comprises:

[0027] The head state detection assembly 1 is installed on the head assembly 4 and includes a positioning unit 101, a first steering axle steering angle sensor 102, a first wheel speed sensor 103, a second steering axle steering angle sensor 104, a second wheel speed sensor 105, The steering wheel angle sensor 106 and the second steering axle electronically controlled steering device 8 . The positioning unit 101 is a satellite positioning system or sensors such as accelerometers, gyroscopes, and magnetic direction sensors to obtain vehicle position information; the first steering axle steering angle sensor 102 and the second steering axle steering angle sensor 104 are installed on the steering wheel of...

Abstract

The invention discloses a control system of a virtual rail bus or train. The control system comprises a vehicle head detection assembly which is mounted on a vehicle head assembly and is used for acquiring a state signal of a vehicle head, a compartment state detection assembly which is mounted on a compartment assembly and is used for acquiring a state signal of a compartment, a vehicle tail state detection assembly which is mounted on a vehicle tail assembly and is used for acquiring a state signal of a vehicle tail, and a trace following controller which is used for reckoning coordinate information of the mass center of each compartment body and coordinate information of each axle according to data detected by the state detection assemblies, wherein the trace following controller transmits a steering instruction to a drive-by-wire steering gear of each axle through a communication network to follow traces of rear wheels and front wheels. The control system of the virtual rail bus or train has the advantages of simple theory, convenient operation, capability of achieving optical control effect and the like.

Description

technical field [0001] The invention mainly relates to the field of urban rail transit systems, in particular to a control system suitable for virtual rail trains. Background technique [0002] The urban rail transit system is a special-line public transportation system with continuous guidance capability, and its characteristic is that it has a whole dedicated track and cannot be mixed with motor vehicles. For example: no crossroads, no crosswalks, no bicycle lanes and no motor vehicle lines in the construction of road subgrades. Usually, urban rail transit systems are mostly built underground or on viaducts. It realizes its free running in the track line by using the blocking mode. The urban rail transit system can also use a fully automated operation mode. In addition, urban rail transit systems are divided into two types: heavy and light, such as subways and light rails. However, this form obviously requires a large investment in infrastructure construction. [0003...
