Problems solved by technology

For the angle sensor in the steering wheel of the vehicle, it can detect the angle and angular velocity of the steering wheel during the running of the vehicle, and provide the necessary data for the electronic steering assist system. If the steering angle data is inaccurate or the data is abnormal, the electronic assist The steering system will fail, which will increase the driver's driving burden and form a safety hazard

Abstract

The invention discloses a testing device and a testing method for a corner sensor, and relates to the technical field of functional verification devices for the angle, the angular speed and additionalfunctions of the corner sensor. The invention in particular relates to the testing device and the testing method for the corner sensor. The device comprises a stepping motor, a bracket, a stepping motor speed reducer, a tested sensor mounting position, a transmission shaft, a transmission shaft fixing device, a chassis, a sensor fixing device and a slide rail, the support, the transmission shaftfixing device and the sliding rail are arranged on the chassis, the stepping motor is arranged on the left side of the support, the stepping motor speed reducer is arranged on the right side of the support, and one end of the stepping motor speed reducer is connected with the stepping motor. After the technical scheme is adopted, the invention has the beneficial effects that under the condition ofunmanned operation, the operation of a driver on a steering wheel can be accurately simulated by running test scripts, and various different driver operation modes can be verified by setting different test scripts.

Description

technical field [0001] The invention relates to the technical field of a function verification device for the angle, angular velocity and additional functions of a rotation angle sensor, in particular to a testing device and a testing method for a rotation angle sensor.
