Bluetooth communication-based vehicle oil quantity indicating system and automatic navigation method

Abstract

The invention discloses a Bluetooth communication-based vehicle oil quantity indicating system and an automatic navigation method. The system comprises a Bluetooth forwarding module and an intelligent mobile phone, wherein the Bluetooth forwarding module is connected with a vehicle ECU (Electronic Control Unit) through an OBD (On-Board Diagnostics) interface to acquire vehicle oil quantity information and accelerator pedal information acquired by the ECU; the vehicle oil quantity information and the accelerator pedal information are forwarded to the intelligent mobile phone; a navigation module, an oil quantity indicating module and a remaining travelable mileage indicating module are arranged on the intelligent mobile phone; and when the remaining travelable mileage is smaller than a preset threshold value, the navigation module automatically searches position information of petrol stations within a remaining travelable range and automatically navigates. Under the condition that a vehicle body structure is not modified, a vehicle oil level indicating function can be transferred to the intelligent mobile phone, vehicle functions are upgraded at a low cost, the remaining travelable mileage can be calculated and displayed on the basis of real-time oil quantity consumption in the process that the intelligent mobile phone indicates vehicle oil quantity, and under the condition of low oil quantity, nearby petrol station information can also be automatically given.

Description

technical field [0001] The invention relates to automotive electronic technology, in particular to an automotive fuel quantity indicating system and automatic navigation method based on bluetooth communication. Background technique [0002] Vehicle fuel level indication is an essential element in vehicle indication information, and is a vehicle parameter that many drivers are very concerned about. During driving, if the vehicle fuel level information is ignored, it will cause passive parking halfway, which will affect driving on the one hand. On the other hand, it increases the proportion of road rescue, causing unnecessary traffic accidents or traffic jams. [0003] In the prior art, vehicles of different manufacturers and models have different fuel quantity indication methods. For high-end brands, the instrument panels have relatively perfect functions and good user experience, but the cost is relatively high. Low-end brands, although the cost is not high, but their instr...

[0002] Vehicle fuel level indication is an essential element in vehicle indication information, and is a vehicle parameter that many drivers are very concerned about. During driving, if the vehicle fuel level information is ignored, it will cause passive parking halfway, which will affect driving on the one hand. On the other hand, it increases the proportion of road rescue, causing unnecessary traffic accidents or traffic jams

[0003] In the prior art, different manufacturers and different models of vehicles have different fuel quantity indication methods. High-end brands have relatively complete instrument panel functions and good user experience, but the cost is relatively high

Low-end brands, although the cost is not high, but their instrument functions are relatively simple, it is relatively difficult to improve from the car body itself, and the existing models prompt the remaining mileage in time, but it is difficult for the driver to judge in time while driving The distance from the gas station, often due to missing the gas station, the fuel-depleted vehicle stalls often occur
