Sensor output signal identification method and device

Abstract

The invention discloses a sensor output signal identification method and device. The method comprises the steps: obtaining an output signal of a target sensor, and extracting the target features of the output signal of the target sensor; and taking the target features as the input of an identification model, and determining the type of the output signal of the target sensor by using the identification model, wherein the category of the output signal comprises any one of rainwater striking and user touch, and the identification model is obtained by training by using a machine learning algorithmbased on historical features, carrying category labels, of the output signals of a plurality of groups of historical sensors. Therefore, the category label of the output signal of the target sensor can be accurately obtained by using the identification model, that is, whether the category of the output signal of the target sensor is rainwater strike or user touch can be accurately identified by using the identification model, and missing identification and error identification are effectively avoided.

Description

technical field [0001] The present application relates to the field of vehicle body control and machine learning, in particular to a method and device for identifying output signals of sensors. Background technique [0002] With the development of vehicle technology, the keyless entry and start system (Passive Entry and PassiveStart, PEPS) has brought great convenience to users. The so-called PEPS means that the user can touch the sensor inside the door handle outside the car door, such as a capacitive sensor, and the door handle recognition module recognizes the level signal output by the capacitive sensor. If the level signal is touched by the user, a control command is sent to the control module to realize the action of opening the car door. [0003] However, in the conventional technology, when the door handle identification module identifies the level signal output by the capacitive sensor, there may be missed identification and false identification. The so-called lea...

AI Technical Summary

Problems solved by technology

The so-called misrecognition means that when rainwater hits the capacitive sensor, the door handle recognition module recognizes the type of the output signal of the capacitive sensor as a user touch, thus causing the control module and even the vehicle control system to execute a cycle corresponding to opening the door. Actions that cause the car's battery to lose power
