Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0024] When driving a vehicle at high speed, the driver's attention is very concentrated and he is always in a state of high mental tension. With the continuous increase of speed and the extension of driving time, the driver will gradually feel tired. Driving on the expressway, the road environment is monotonous, the traffic interference is less, the speed is stable, the noise and vibration frequency during driving are small, it is easy to make the driver feel monot...

The invention provides a driving prompt system. The driving prompt system comprises a speed sensor, a first analog-digital converter, a steering wheel sensor, a second analog-digital converter, a controller and a vibration device, wherein the speed sensor is connected to the output end of an engine and used for outputting a vehicle speed signal; the first analog-digital converter is connected to the output end of the speed sensor and used for converting the vehicle speed signal from an analog form to a digital form; the steering wheel sensor is connected to a steering wheel and used for outputting a steering wheel turning angle signal; the second analog-digital converter is connected to the output end of the steering wheel sensor and used for converting the steering wheel turning angle signal from the analog form to the digital form; the controller is used for receiving the vehicle speed signal and the steering wheel turning angle signal which are in the digital form, enabling a virtual timer to time through programs when the variation ranges of the vehicle speed signal and the steering wheel turning angle signal are smaller than reference values at the same time, and outputting a control signal when timing time is up; the vibration device is arranged under a driver seat and used for receiving the control signal and vibrating according to the control signal.
Description
technical field [0001] The invention relates to the field of vehicle electronics, in particular to a driving prompt system. Background technique [0002] The development of automobiles not only has a huge effect on social economy, but also has an important impact on human life. Automobiles have become the main means of transportation for people to travel, and their convenience is unmatched by airplanes, ships and trains. [0003] As an emerging economy, China has become the world's largest automobile consumer. At present, the number of motor vehicles in my country has exceeded 100 million. [0004] Driving fatigue refers to the phenomenon that the driver's physiological function and psychological function are out of balance after driving continuously for a long time, and the driving skill declines objectively. The driver's sleep quality is poor or insufficient, and he is prone to fatigue after driving for a long time. Driving fatigue can affect various aspects such as dri...
