Method for identifying vehicle steering process

Abstract

The invention provides a method for identifying vehicle steering process. The method includes the following steps: calculating yaw angular velocity short-term average energy in preset time at a firstcalculation moment; when the yaw angular velocity short-term average energy calculated at the first calculation moment is greater than a first set threshold, recording the first calculation moment asa start time of the vehicle steering process; calculating yaw angular velocity short-term average energy in preset time at a second calculation moment; and when the yaw angular velocity short-term average energy calculated at the second calculation moment is less than a second set threshold, recording the second calculation moment as an end time of the vehicle steering process. Since the steeringprocess is identified based on the yaw angular velocity short-term average energy, compared with a conventional direct identification method using yaw angular velocity signals, the method of the invention has high roughness to micro-steering operation in a driver operation process, and the start point and the end point of the steering operation can be more easily and accurately determined.

Description

technical field [0001] The invention relates to a method for identifying a vehicle steering process. Background technique [0002] Conventionally, there is known a method of directly recognizing the steering process of the vehicle based on the yaw rate. However, the direct recognition based on the yaw rate signal is too sensitive to the small change of the driver's steering wheel angle, and will recognize the driver's small correction operation and other unconscious steering processes during the straight-line driving of the vehicle. The start point and end point of the steering process. Contents of the invention [0003] In view of the above circumstances, the present invention aims to provide a method for recognizing a vehicle steering process that has high recognition accuracy and can more easily and accurately determine the start point and end point of the steering process. [0004] The technical scheme adopted in the present invention is: [0005] An embodiment of t...
