Vehicle oil quantity indicating system and its indicating information switching control method

Abstract

The invention discloses a vehicle oil quantity indication system and an indication information switching control method thereof. The vehicle oil quantity indication system comprises a Bluetooth forwarding module and a smart phone matched with the Bluetooth forwarding module. The Bluetooth forwarding module is connected with an automobile ECU through an OBD interface. The automobile ECU is electrically connected with an oil quantity sensor, an accelerator sensor, an emergency lamp button, a wheel rotating speed sensor, a motor rotating speed sensor and a temperature sensor. The smart phone is provided with a navigation map display interface, an oil level indication interface, an engine parameter display interface and a vehicle operation parameter display interface. The emergency lamp button is used for generating a switching instruction. According to the vehicle oil quantity indication system and the indication information switching control method thereof, function upgrading is conducted on an existing low-end vehicle, and on one hand, the indication function of oil quantity information and other operation parameters is achieved through the smart phone, and on the other hand, the emergency lamp button arranged on the vehicle is utilized to achieve control over display information of the smart phone.

Description

technical field [0001] The invention relates to automobile electronic technology, in particular to a vehicle fuel quantity indicating system and a method for controlling switching of indicating information. Background technique [0002] The vehicle fuel level indication is an essential element in the 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 i...

[0002] The vehicle fuel level indication is an essential element in the 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

[0004] In addition, even if some products realize the use of smart terminals to display vehicle information, it is difficult to directly use the controls on the car body to control the smart terminals during driving. The interface is relatively small, if you want to operate it yourself, it will inevitably distract the driver, and it is difficult to avoid the risk of causing traffic accidents
