Problems solved by technology

However, the recognition accuracy is low, especially in the case of insufficient light, and it is often difficult to distinguish. If a high-definition, high-sensitivity light-sensitive camera is used to solve the problem, it will lead to a significant increase in equipment cost and volume.

Abstract

The invention discloses a driver identity identification device. The driver identity identification device comprises a controller, an output interface which is connected with the controller and outputs an identification signal, and a camera and a pressure sensor which acquire driver head portrait and body weight signals to the controller. The invention has the advantages that 1, the identity of a driver is identified, and the body weight measurement of the driver of the pressure sensor is added; in normal situations, the distinction degree of the body weight characteristic is very obvious and is not affected by light rays in a vehicle and the coat dress of the driver; and the identity identification accuracy of the driver can be greatly improved by combining the driver head portrait information characteristics acquired by the camera and a reasonable algorithm; and 2, the adopted pressure sensor is a universal sensor, is low in cost, simple in structure, and wide in application; and compared with the modes such as fingerprint scanning and retina scanning, the driver identity identification device is easy to obtain, and the cost advantage is obvious.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a device for driver identity automatic identification technology. Background technique [0002] With the increasing popularity of automotive electronic information technology and the continuous improvement of people's requirements for driving comfort, the automatic and personalized configuration of car driving parameters has become a highlight of high-end car configuration. For example, according to the different drivers, it can automatically adjust the driving parameters such as the seat position, the wind power of the air conditioner, and the position of the rearview mirror, so that the driver can obtain the most comfortable driving experience. If an illegal driver is detected, it can also send out an audible and visual alarm or even cut off the power of the car. One of the most critical devices is the driver identification device. There are two main implementations of d...
