Description

Technical Field

[0001] The present invention relates to the technical field of intelligent driving, and in particular to a steering wheel steering misoperation warning method, device, equipment, system, storage medium and vehicle. Background Art

[0002] During the use of the vehicle, safety accidents often occur due to improper operation of the steering wheel by the user. For example, during driving, when turning a wide bend or in an emergency avoidance scenario, the user often slams the steering wheel, causing the steering angle of the steering wheel to be too large, which can easily cause the vehicle to skid or tilt too much and cause safety accidents; during parking, when the car is rubbed too many times, the user is likely to forget the current steering wheel position, making it difficult to adjust it correctly to the center position, resulting in the user being unable to park correctly in the parking space, greatly affecting the parking / driving efficiency, and even causing scratches and collisions; when parking, the user is likely to forget to return the steering wheel to the center, causing the front wheels of the parking wheel to bear static loads and damage the steering system, and it is easy to scratch when the vehicle starts; and some users habitually do not hold the steering wheel in the correct posture, such as not placing both hands on the left and right center, but on the upper or lower position of the left and right center, which will lead to the inability to correctly grasp the current steering wheel angle. Therefore, it is very necessary to design a method or product that can warn the driver of misoperation of the steering wheel, but there is currently no product in the automotive market that can warn the driver of misoperation of the steering wheel.
