Problems solved by technology

However, the disadvantages of this approach are also obvious. Unplug the speed sensor, there is no speed display, and it is easy to cause driving anxiety; unplug the ABS system, which seriously affects driving safety.
Therefore, for the data memory problem of commercial vehicle dispatching and transportation, there is currently no method that takes into account safety, economy, versatility, and portability

Abstract

The invention relates to a data memory method and device based on a scheduling mode, and the method comprises the steps: firstly, judging whether a scheduling mode triggering condition is established or not, if so, entering a scheduling mode, enabling a vehicle to be in the scheduling mode, enabling a vehicle-mounted controller to perform data collection, processing and storage normally, and enabling a vehicle-mounted display device to display a mileage value and an outgoing mileage value to be 0; and in the scheduling mode, judging whether a scheduling mode exit condition is established or not, if so, exiting the scheduling mode, and resetting the mileage data stored in the vehicle-mounted controller. According to the invention, a main engine plant is facilitated to reduce the sales and transportation cost of the whole vehicle, meanwhile, other problems are not generated, and safety, economy, universality and portability are fully considered.

Description

technical field [0001] The invention relates to the technical field of vehicle data storage, in particular to a data memory method and device based on a scheduling mode. Background technique [0002] With the rapid advancement of automobile electrification, intelligence, networking, and sharing, the amount of automobile data has shown an unprecedented blowout growth trend, which has raised many new issues in the fields of data collection, processing, and storage. [0003] In the prior art, in terms of data storage and backup, the ECU stores data based on time based on the type of current mode power supply, and also saves data based on event triggers. For example, the mileage of a car is generally specified how many kilometers to save once or when the power is turned ON. The general saving strategy is relatively fixed. Once saved, the user cannot modify it. [0004] Consider a scenario where a vehicle is rolled off the assembly line from the assembly plant to the dealer’s sa...
