Automobile speed limitation and maintenance reminding method and vehicular speed limitation and maintenance reminding system

Abstract

The invention provides an automobile speed limitation and maintenance reminding method and a vehicular speed limitation and maintenance reminding system, and relates to the field of automobile safety. According to the reminding method, real-time driving speed value of an automobile is detected, a preset driving speed value inputted by a user is acquired, the real-time driving speed value and the preset driving speed value are compared, different real-time driving speed values adopt different alarm modes to remind users to pay attention to decelerate and slowly drive, unsafe accidents caused by divided attention due to viewing an instrument panel in the driving process are avoided, accumulated mileage is acquired based on accumulated real-time driving speed value, the accumulated mileage and preset mileage are compared, the user is reminded when the automobile needs to be maintained, the preset driving speed value is inputted, road information cannot be acquired by GPS (global position system) signals, and the reminding method solves the problem that navigation software is opened, so that over-speed is reminded, and GPS signals are unstable. After the automobile stops, a system enters dormancy, a power supply of an input unit is turned off, the input unit cannot receive preset driving speed values inputted by users, and energy consumption is reduced.

Description

Technical field [0001] The invention relates to the field of automobile safety, in particular to a method for reminding automobile speed limit and maintenance and a vehicle-mounted speed limitation and maintenance reminding system. Background technique [0002] With the rapid development of automotive electronics technology, the functional complexity of vehicles is increasing, safety, environmental protection, and energy-saving regulations are becoming stricter. Customer needs for comfort, flexibility, and individualization vary widely. Global market competition has shortened the development cycle. , A large number of electronic controllers are widely used in automobiles, leading to huge challenges in the development of vehicle diagnostics. [0003] When the vehicle is driving, taking into account the road speed limit or safety issues, a series of speed limit methods will be used to limit the speed. It is more common to limit the speed through the speed detection included in the n...

Problems solved by technology

[0004] However, if the navigation software is used to remind speeding, the navigation software must be turned on all the time, and it cannot be reminded when the software is not turned on.

The alarm made of GPS is affected by the GPS signal. In places where there is no GPS signal, such as tunnels, the speed cannot be obtained, and the alarm function cannot be played.

In addition, when the car navigation software sends out an alarm signal, the driver will generally inadvertently compare it with the car instrument, and at the same time will produce a visual blind spot, especially when the distance between the front car and the car is relatively close, accidents are likely to occur

And the vehicle needs to be maintained after driving a certain mileage, and the user needs to remember the mileage of the car during the last maintenance to know the mileage of the car after the last maintenance. Users tend to forget or misremember the mileage of the last maintenance And lead to unnecessary waste of excessive maintenance of the vehicle or lack of maintenance will affect the operation of the car engine and reduce the service life of the vehicle
