Hand-off driving monitoring method and device as well as vehicle and storage medium

Abstract

The invention relates to the technical field of vehicles, in particular to an off-hand driving monitoring method and device as well as a vehicle and a storage medium. The method comprises the following steps: obtaining temperature parameters of the surface and / or the nearby position of a steering mechanism; and judging whether or not the vehicle is currently in an off-hand driving state accordingto the temperature parameters. According to the off-hand driving monitoring method and device as well as the vehicle and the storage medium provided by the invention, the temperature parameters replace pressure or torsion parameters to serve as judgment basis of off-hand driving, and whether or not the driver adopts off-hand driving can be detected without applying force to the steering mechanismby the driver, thereby achieving a low misjudgment risk, small data calculation amount and low manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hands-off driving monitoring method, device, automobile and storage medium. Background technique [0002] The steering wheel is the main steering mechanism used by many vehicles such as automobiles, and the driver controls the direction by turning the steering wheel. Leaving hands off the steering wheel for a long time can easily lead to traffic accidents. Therefore, many cars will monitor and remind the behavior of hands-off driving. [0003] There are currently three main monitoring methods for hands-off driving, which are as follows: [0004] ①Install a pressure sensor on the steering wheel: If the hand holds the steering wheel tightly, the pressure sensor senses the pressure value, and the system judges that the driver is holding the steering wheel; if the hand does not hold the steering wheel tightly, the pressure sensor cannot sense the pressure value, and the system...

AI Technical Summary

Problems solved by technology

[0008] Monitoring methods ① and ② both require the driver’s hands to be in contact with the steering wheel and generate a large external force to the steering wheel; however, in many cases, especially when the car is driving straight, the driver’s hands may only be lightly placed on the steering wheel, It is not enough to generate a large pressure or torque, so it is difficult to trigger the pressure sensor and torque sensor. At this time, the system is easy to misjudge that the driver is in a state of hands-off driving;

[0009] Monitoring method ③ too high requirements for image processing technology

On the one hand, the speed of the car is very fast, so the speed of image analysis must be very fast, otherwise it is easy to cause the analysis results to seriously lag behind the actual driving state; Greatly increases the difficulty of visual image processing

Therefore, the monitoring method ③ has higher requirements on hardware devices such as memory and processing unit, and correspondingly, the manufacturing cost is also higher
