Abstract

The invention discloses a calibration method and device for a steering angle sensor and relates to the information processing technology to solve the problems that in the process of calibrating a steering angle sensor in the prior art, operation is complex, and calibration time is long. The method includes the steps that automatic driving is performed according to a preset linear track, and calibration data in the automatic driving process is acquired; a high-precision calibration interval of the steering angle sensor is calibrated according to the calibration data collected in automatic linear driving; left steering closed track driving and right steering closed track driving are performed respectively in a manual driving mode, and left steering calibration data and right steering calibration data are acquired; low-precision calibration intervals except the high-precision calibration interval of the steering angle sensor are calibrated according to the left steering calibration data and the right steering calibration data. According to the technical scheme, the calibration method and device can be applied to automatic driving devices of agricultural machines.

Description

technical field [0001] The invention relates to information processing technology, in particular to a calibration method and device for a steering angle sensor. Background technique [0002] To achieve high-precision automatic driving control of agricultural machinery, it is necessary to ensure high-precision calibration of the steering angle sensor of agricultural machinery. The calibration method of the steering angle sensor in the prior art is: to perform high-precision calibration on all angles within the value range of the steering angle sensor. The specific steps may include: according to the value range of the steering angle sensor, respectively setting the left steering trajectory and the right steering trajectory, such as figure 1 As shown; the driver drives the agricultural machine manually according to the left steering trajectory and the right steering trajectory, and obtains the position data during the manual driving process; according to the position data and...
