Sensing device for behavior recognition of driver and recognition method thereof

Abstract

The invention discloses a sensing device for behavior recognition of a driver and a recognition method thereof. The sensing device comprises a camera, an image processor, an intention recognition processor and a power supply module. The camera is connected with the image processor; the image processor is connected with the intention recognition processor; the intention recognition processor is connected with a vehicle CAN through a CAN bus; the camera is installed on the upper front portion of a driver seat; and the included angle between the primary optical axis of the camera and the horizontal plane is 30-60 degrees, and a camera lens faces downwards. According to the method, intentions of the driver are divided into decelerating, vehicle following, braking and steering. The steering intention is recognized based on the head turning angle and frequency, and the turning angles of a steering lamp and a steering wheel; the decelerating and vehicle following intentions are recognized based on the open degree and the starting speed of an accelerator and the gear; and the braking intention is recognized based on a braking switch, the releasing speed of an accelerator pedal and the gear. The misrecognition problem caused by an abnormal single signal can be effectively solved, and recognition accuracy is improved.

Description

technical field [0001] The invention relates to a sensing device, more specifically to a driver behavior recognition sensing device and a recognition method thereof, belonging to the technical field of automobile driving assistance systems. Background technique [0002] Automotive Driver Assistance System (ADAS) will warn the driver or directly control the vehicle before the danger occurs, which requires the identification of the driver's intention for reasonable intervention. If the driver's intention cannot be effectively recognized, the system will give false warnings and brakes, which will annoy the driver and may even lead to accidents; as ADAS is more and more widely used, it is necessary to accurately obtain the driver's driving intention Information becomes a burning problem. [0003] At present, the existing driver identification functions are all integrated in different ADAS controllers, and the driver's intention is often identified through a single signal such a...
