Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sensors and relates to an electronic speed sensor. Background Art
[0002] With the development of technology, vehicles are popularized. For driving safety, vehicle accessories need to be tested, such as post-production testing or in-operation testing. To ensure the accuracy of the test results of the vehicle braking performance, when installing the speed sensor, the installation surface of the speed sensor should be perpendicular to the ground so that the arrow direction of the acceleration sensor is the same as the vehicle forward direction. In the prior art, the speed sensor is usually installed on a plane of the vehicle body that is relatively perpendicular to the ground, and it is generally fixed to the plane at the rear of the middle platform by strong tape to ensure the consistency of the arrow direction of the acceleration sensor and the vehicle forward direction. However, in the actual test process, since the vehicle needs to simulate jitter when driving, the measured value of the speed sensor is inaccurate, affecting the accuracy of the performance test results. At the same time, for its data reading, it generally needs to be transmitted to the terminal for display, and there is a certain distance between the two, so it cannot be observed in time, thus not meeting the use requirements.
