Vehicle-mounted vehicle driving deviation detection apparatus and detection method

Abstract

The invention discloses a vehicle-mounted vehicle driving deviation detection apparatus and detection method. The vehicle-mounted vehicle driving deviation detection apparatus includes a magnetic attraction seat, a vehicle terminal, and a wireless laser bar code scanner. The vehicle terminal is composed of a GPS positioning module, a single-chip microcomputer main control module, a data transmission and display module, an interface module, an alarm module and a power module. The host of a mobile station acquires the vehicle trajectory information in real time and sends the information to a reference station via a radio station in the host, a differential algorithm is formed in the system to obtain the high-precision mobile station coordinate, the deviation amount of the vehicle to be measured is processed and calculated through the main control chip of the single-chip microcomputer main control module, the result of the deviation amount is displayed on a four-bit digital display screen after the testing is finished, and the vehicle speed is displayed in the testing process in real time. The apparatus is simple in structure and convenient to detach, and can realize the display of the deviation amount and the vehicle speed, is suitable for automobile manufacture enterprises to do streamline test, and has wide market potential and application prospect.

Description

technical field [0001] The invention belongs to the technical field of vehicle performance testing, and in particular relates to a vehicle-mounted vehicle deviation detection device and detection method. Background technique [0002] Running deviation is the phenomenon that when the vehicle is driving straight on a flat road, it deviates to one side by itself, resulting in the phenomenon that the line connecting the center of the front and rear axles of the vehicle is inconsistent with the driving direction. Vehicle deviation is more harmful, ranging from gnawing tires and scrapping tires, to causing dangerous driving conditions such as tire blowouts and vehicle loss of control. Therefore, it is very important to detect vehicle deviation. [0003] At present, there are few devices that can be used to detect vehicle deviation, mainly including gyroscope and V-BOX non-contact vehicle tester. The gyroscope measures the acceleration of the carrier in the inertial reference syste...

Problems solved by technology

The hardware line connection of the system is complicated, the data transmission network environment is very demanding, and all of them use wireless network transmission. Radio frequency interference will delay the time for users to send and receive data, and cause conflicts, which is difficult to meet the high-intensity and high-frequency pipeline detection.
