Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the technical solution and design principles of the present invention will be described in detail below only with an optimized technical solution, but the protection scope of the present invention does not limited to this.

[0036] Such as figure 1 The large vehicle turn warning system shown includes GPS positioning module, radar combination module, six-axis sensor, steering wheel angle sensor, electronic control unit ECU (Electronic Control Unit), body control module BCM (Body Control Module), lighting module, audio Generator, CAN bus and vehicle speed sensor; Among them, the electronic control unit ECU is used to obtain signals from the GPS positioning module, six-axis sensor, and steering wheel angle sensor through the CAN bus, determine the system working mode (turning or changing lanes), and calculate the comple...

Abstract

The invention relates to an oversize vehicle turning early warning method and system. The system starts to work when a steering lamp is turned on, an electronic control unit (ECU) acquires the steering angle of the steering wheel and GPS positioning information, judges the driving intention of a driver, and determines the turn-on mode of an indicator light belt, then the ECU obtains data of a vehicle speed sensor and a six-axis sensor, and an occupied road width range calculation model based on two degrees of freedom is established to determine the road width range to be occupied by the steering inner side. After the range is obtained, a body control module (BCM) uses the indicator light belt to mark the road width range to be occupied on the ground. radar combination module is started todetect obstacles on the steering inner side and determine the position, and if the obstacles exist in the road width range to be occupied, the vehicle body control module BCM gives out a prompt toneto remind the driver to pay attention to avoidance. The road surface through which an oversize vehicle is about to pass can be clearly marked, and surrounding vehicles and pedestrians are effectivelyreminded to avoid.

Description

technical field [0001] The invention belongs to the field of large vehicle turning early warning systems, and in particular relates to a large vehicle turning early warning method and system. Background technique [0002] When a large vehicle is turning, the running tracks of the front and rear wheels are different, and the rear wheels do not follow the track of the front wheels, and a deviation will occur. This deviation is called the inner wheel difference. The greater the length of the vehicle, the greater the resulting inner wheel differential. In truck accidents, the accidents caused by the inner wheel difference account for a large proportion. When the truck is turning, if the pedestrians or vehicles on the turned side are relatively close, accidents may occur where the front of the vehicle does not collide but the rear of the vehicle collides, and the middle and rear of the vehicle are in the driver's visual blind spot. Unable to respond to emergencies in time, lead...
