Description

A driving reminder method and device

This application claims the priority of the Chinese patent application with the application number 202110353633.0 and the invention titled "A Driving Reminder Method and Device", which was submitted to the State Intellectual Property Office of China on April 1, 2021, the entire contents of which are incorporated herein by reference Applying.

technical field

The present application relates to the field of intelligent driving, and more particularly, to a driving reminder method and device.

Background technique

At present, with the continuous development of technology, the electronic equipment in the car can provide the driver with services such as navigation, music and voice calls. However, in the process of driving the car, if the driver's attention is focused on the electronic device for a long time, the time for the driver to pay attention to the road conditions will be reduced, which is prone to traffic accidents.

To this end, the existing driving reminder method mainly includes the following steps: First, the driving speed of the vehicle where the driver is located is obtained. Secondly, if the driving speed of the vehicle in which the driver is located is greater than the preset speed, record the length of time that the driver watches the electronic device. Thirdly, if the driver watches the electronic device for longer than the safe time, then output safe driving prompt information to avoid the driver from causing a traffic accident.

Based on the above steps, it can be known that the traditional driving reminder method mainly determines whether the driver is in a dangerous driving state according to the driving speed of the vehicle the driver is in and the length of time the driver watches the electronic device. If it is determined that the driver is in a dangerous driving state, safe driving prompt information is output.

However, the above-mentioned existing driving reminder methods only focus on the driving speed of the driver's vehicle and the length of time the driver watches the electronic device, ignoring the relationship between the vehicle and other vehicles, that is, without considering the possible occurrences between the vehicle and other vehicles. Therefore, the above-mentioned existing driving reminder methods cannot provide appropriate safe driving reminder information based on the conditions of other vehicles around the vehicle.

Therefore, how to give appropriate safe driving prompt information based on the conditions of surrounding vehicles has become an urgent problem to be solved at present.
