Problems solved by technology

At present, the articulation angle parameters of automobile trains are generally measured directly by angle sensors. This measurement method is more suitable for full-trailer trains, but for semi-trailer trains, due to the particularity of the saddle structure and the difference in s

Abstract

The invention relates to a truck combination hinge angle measuring and controlling system, which mainly consists of a truck combination hinge angle measuring portion and a hinge angle controlling portion and particularly comprises a GPS (global positioning system) tester, input equipment, a microprocessor, a steering wheel rotation angle sensor, a driving front-wheel steering controller, an executing mechanism and power supply equipment. The GPS tester, the input equipment and the steering wheel rotation angle sensor are respectively connected with the microprocessor, the steering wheel rotation angle sensor is connected with a steering wheel of the truck combination, the microprocessor is connected with the driving front-wheel steering controller which is connected with the executing mechanism, the executing mechanism is connected with a truck combination steering mechanism, and the power supply equipment supplies power for the integral system. By the truck combination hinge angle measuring and controlling system, truck combination hinge angle can be measured accurately, steering harmony and running stability of the truck combination during insufficient steering and over-steeringcan be effectively controlled by the truck combination hinge angle measuring and controlling system utilizing the hinge angle as control variable.

Description

technical field [0001] The present invention relates to vehicle handling stability, and more specifically, the present invention relates to a combined vehicle steering articulation angle measurement and control system comprising a motor tractor and a trailer. Background technique [0002] The automobile train is a combined vehicle composed of motor tractors and trains articulated. Due to the connection and interaction between the vehicles through the hinge mechanism, the dynamic characteristics of the vehicle are more complicated than that of a single vehicle. At present, the control method and system of single-vehicle handling stability have been relatively mature. Tilting control technology has gradually emerged and developed widely. The most important control variables of the current control method are yaw rate, lateral acceleration, side slip angle, and roll angle, etc., which have a good effect on the stability of single-vehicle handling, but for automobiles and trains...
