Abstract
The invention discloses a steering wheel with a fatigue driving prompt function, which comprises a steering wheel body; the heart rate sensor is arranged on the steering wheel body and used for detecting the heart rate of a driver and outputting a heart rate signal; the processor is in signal connection with the heart rate sensor and is used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and the alarm device is in signal connection with the processor and is used for generating a prompt signal when the driver is in fatigue driving. The steering wheel can detect whether the driver is in a fatigue state in real time, and advises the driver to stop for a rest when judging that the driver is in the fatigue state.
Description
Technical Field
The invention relates to the technical field of driving assistance systems, in particular to a steering wheel with a fatigue driving prompting function.
Background
The driving fatigue refers to a phenomenon that a driver has a decreased driving skill objectively due to disorder of physiological and psychological functions after driving for a long time. The driver has poor or insufficient sleeping quality, and is easy to have fatigue when driving the vehicle for a long time. Driving fatigue affects the driver's attention, feeling, perception, thinking, judgment, consciousness, decision and movement. The factors that cause fatigue driving are manifold. Fatigue of drivers is mainly fatigue of nerves and sense organs, and fatigue of limbs caused by poor blood circulation due to long-term fixed posture. When a driver sits on a fixed seat for a long time, the action is limited to a certain degree, the attention is highly concentrated, the driver is busy judging stimulation information outside the vehicle, and the mental state is highly tense, so that the driving fatigue phenomena of blurred eyes, waist soreness and backache, slow response, inflexible driving and the like occur. The order of fatigue development is: it is also a considerable aspect that the eyes, neck, shoulders, waist, mainly the fatigue of the eyes and body and also the brain.
The existing eyeball tracking anti-fatigue technology can generally directly control the automobile to be flameout after multiple reminding or ineffective reminding after detecting the fatigue driving of a driver, and the direct flameout of the running vehicle has great influence on the rear vehicle, thereby easily causing safety accidents.
Disclosure of Invention
The purpose of the present invention is to provide a steering wheel that can prevent fatigue driving by a driver.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a steering wheel with a fatigue driving prompting function, comprising: a steering wheel body; the heart rate sensor is arranged on the steering wheel body and used for detecting the heart rate of a driver and outputting a heart rate signal; the processor is in signal connection with the heart rate sensor and is used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and the alarm device is in signal connection with the processor and is used for generating a prompt signal when the driver is in fatigue driving.
Further, the steering wheel body is provided with an irritant gas sprayer, and the irritant gas sprayer is in signal connection with the processor.
When the processor judges that the driver is in a fatigue state, the control module sends a starting signal to the irritant gas sprayer, and the irritant gas sprayer sprays irritant gas to the driver.
Compared with the prior art, the invention has the following technical effects:
according to the steering wheel, the heart rate sensor is arranged on the steering wheel body, the hands of a driver press the steering wheel body for a long time when the driver drives a car, the heart rate sensor obtains a real-time heart rate signal of the driver through contact with the hands of the driver, and the processor processes the heart rate signal obtained by the heart rate sensor to judge the fatigue degree of the driver; when the processor judges that the driver is in a fatigue state, the processor controls the alarm device to generate prompt information; the invention can detect whether the driver is in the fatigue state in real time, and advises the driver to stop for rest when judging that the driver is in the fatigue state.
For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic view of the structure of a steering wheel of the present invention.
Detailed Description
Referring to fig. 1, a steering wheel with fatigue driving prompt function includes a steering wheel body; the heart rate sensor is arranged on the steering wheel body and used for detecting the heart rate of a driver and outputting a heart rate signal; the processor is in signal connection with the heart rate sensor and is used for receiving and processing the heart rate signal to judge the fatigue degree of the driver; and the alarm device is in signal connection with the processor and is used for generating a prompt signal when the driver is in fatigue driving.
Preferably, the steering wheel body is provided with a vehicle speed detection device and an irritant gas sprayer, and the vehicle speed detection module and the irritant gas sprayer are respectively in signal connection with the processor.
When the vehicle speed detection module detects that the running speed of the vehicle is greater than 0 and the processor judges that the driver is in a fatigue state, the control module sends a starting signal to the irritant gas sprayer, and the irritant gas sprayer sprays irritant gas to the driver.
According to the steering wheel, the heart rate sensor is arranged on the steering wheel body, the hands of a driver press the steering wheel body for a long time when the driver drives a car, the heart rate sensor obtains a real-time heart rate signal of the driver through contact with the hands of the driver, and the processor processes the heart rate signal obtained by the heart rate sensor to judge the fatigue degree of the driver; when the processor judges that the driver is in a fatigue state, the processor controls the alarm device to generate prompt information; the invention can detect whether the driver is in the fatigue state in real time, and advises the driver to stop for rest when judging that the driver is in the fatigue state.
Furthermore, an irritant gas sprayer connected with the processor is arranged on the steering wheel body; when the processor judges that the driver is in a fatigue state, the processor controls the exciting gas sprayer to be started to spray exciting gas to the driver, so that the driver is prevented from neglecting the prompt information and continuing driving.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
