Wheel attitude angle online measurement device

Abstract

The invention discloses a wheel attitude angle online measurement device. The device comprises a magnetic base and further comprises a wheel and a diffused reflection plate installed at the side of the wheel, wherein the magnetic base is provided with a large arm fixing base, the large arm fixing base is provided with a large arm fixing rod, a round cross fixing clamp and a small arm telescopic rod are sleeved on the large arm fixing rod, the small arm telescopic rod is installed on the large arm fixing rod by using the round cross fixing clamp, a plurality of infrared measurement devices areuniformly installed on the diffused reflection plate, one end of the infrared measurement device is provided with a measurement installation plate, one end of the measurement installation plate is provided with a measurement plate base, and the measurement plate base is fixedly connected with the small arm telescopic rod. The wheel attitude angle online measurement device adopts a non-contact measurement manner as well as a principle of determining a plane through three points, calculates and outputs turning angles and other attitude angles of a wheel online in real time, and feeds back to a driving robot for closed loop feedback control, thereby solving a technical problem of measuring wheel turning angle online.

Description

technical field [0001] The invention relates to an online measuring device for a wheel attitude angle, belonging to the technical field of intelligent measuring devices. Background technique [0002] At present, smart cars are developing at a high speed. In order to give better feedback on the control and operation capabilities of smart cars, the corresponding test equipment should also follow the pace to continuously improve the detection accuracy and control accuracy. Only higher precision test capabilities can be real. Feedback the real control ability and response ability of smart cars; only the testing ability with higher precision can better help the development of smart cars. In the smart car bench simulation test, the manufacturer of the driving robot cannot monitor and test the vehicle steering action directly online, and can only estimate the steering angle of the wheel through the angle of the steering wheel and transmission parameters, especially in indoor dynami...
