[0002] With the increasing of the automobile ownership, the automobile oil consumption problem is increasingly concerned. The high and low of oil consumption not only affects the use cost of the owner, but also has important significance to energy consumption and environmental protection. At present, the automobile driver often lacks intuitive understanding and timely and effective reminding mechanism for the oil consumption influencing factors in the driving process, resulting in that some driving behaviors and vehicle working conditions continuously increase the oil consumption, but the driver is unaware. For example, the sudden acceleration, the sudden brake, the long time idling, the unreasonable gear use, the tire pressure anomaly, the engine fault and the like can all make the oil consumption greatly increase, but the driver is difficult to realize the influence of these problems on the oil consumption in real time in the driving process. The continuous high oil consumption can mean that the vehicle has some potential problems, such as the engine carbon deposit, the spark plug fault, the tire pressure deficiency and the like. The oil consumption monitoring system in the prior art only detects the remaining oil quantity, and there is a technical problem that the real time data information and the automobile driving information of the vehicle cannot be used to respectively monitor the scientific calculation of the oil consumption and the prompt.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model discloses a fuel consumption warning system for heavy-duty vehicles, such as... Figure 1 As shown, the system includes a data acquisition module, a data processing module, an early warning module, and a display module. The data acquisition module is connected to the data processing module, which in turn is connected to the early warning module and the display module. The early warning module is also connected to the display module. The data acquisition module includes an operational data acquisition unit, an environmental data acquisition unit, and a status data acquisition unit, used to collect vehicle operation data, environmental data, and vehicle status data during vehicle operation. The data processing module processes the collected data. The early warning module includes an early warning information generation unit and an early warning prompt unit, used to generate fuel consumption early warning information and prompt the driver. The display module is used to display the data and early warning prompt information.

[0018] Furthermore, the operational data acquisition unit is connected to the electronic control unit of the heavy-duty vehicle to collect information such as driving speed, engine speed, throttle opening, gear information, braking status, and mileage.

[0019] Furthermore, the environmental data acquisition unit is installed on the exterior of the heavy-duty vehicle and includes temperature sensors, humidity sensors, and air pressure sensors.

[0020] Furthermore, the status data acquisition unit includes tire pressure sensors installed inside the tires of heavy-duty vehicles, fuel consumption sensors installed in the fuel system, and temperature and vibration sensors installed in key parts of the engine.

[0021] In this embodiment of the utility model, the fuel consumption sensor is responsible for monitoring the fuel consumption data of the vehicle in real time. It is usually installed in the oil line between the fuel tank and the engine, and can be installed without damage. It measures the basic data such as the fuel consumption and working time of the engine through a high-sensitivity volumetric flow sensor. The status data acquisition unit also includes a positioning device and a load sensor. The positioning device includes a GPS device and a slope sensor, which can monitor the position, slope and speed of the heavy-duty vehicle in real time. The load sensor can use a pressure sensor or a tire pressure sensor to measure the load of the heavy-duty vehicle.

[0022] In this embodiment of the invention, the characteristic parameters of fuel consumption are as follows: Figure 2As shown, time refers to the impact of time factors on fuel consumption, specifically broken down into: seconds, minutes, hours, days, and months; location refers to the impact of geographical location on fuel consumption, specifically broken down into: longitude (east-west coordinates), latitude (north-south coordinates), and elevation (altitude); motion state refers to the state of the vehicle during driving, specifically broken down into: average speed under heavy load (average speed under load), average speed under no-load (average speed under no-load), and load (weight carried by the vehicle); inherent attributes refer to the attributes of the vehicle itself, specifically broken down into: vehicle model (model or type), vehicle age (years of use), and conversion efficiency (efficiency of power conversion); external factors refer to other influencing factors besides the vehicle itself and driving behavior, specifically broken down into: driving behavior (driver's driving habits and style), temperature (the impact of ambient temperature on fuel consumption), distance traveled (distance traveled), elevation difference (elevation difference of the driving route), and slope (gradient of the driving route).

[0023] In this embodiment of the invention, the system calculates the vehicle's real-time fuel consumption based on the fuel consumption measured by the fuel consumption sensor per unit time, combined with parameters such as vehicle speed and driving time, using the formula: Fuel Consumption = Fuel Consumption / Driving Mileage. For example, if the fuel flow sensor detects that 5 liters of fuel are consumed in 1 hour during a driving period, and the vehicle travels 50 kilometers in that hour, then the real-time fuel consumption is 5 / 50 = 0.1 liters / km.

[0024] The judgment of the warning information is based on the comparison between real-time fuel consumption and standard fuel consumption data pre-stored in the system. The standard fuel consumption data is derived from the vehicle model, engine parameters, transmission type and a large amount of actual road test data.

[0025] Furthermore, the display module includes an instrument panel display and a mobile portable terminal.

[0026] In this embodiment of the utility model, the display module is the output part of the system, which displays real-time fuel consumption data and alarm information to the driver or system administrator. The display module intuitively shows the changes in the vehicle's fuel consumption and displays them in the form of charts. At the same time, it can be compared with the driving mileage to help the manager judge whether the fuel consumption is reasonable.

[0027] In addition to displaying warning information in the form of text and icons, the display module also conveys information to the driver in a clear and easy-to-understand voice through a voice prompt system, ensuring that the driver can obtain fuel consumption warnings in a timely manner while driving.

[0028] Furthermore, it also includes a storage module, which is connected to the data processing module and the display module, and is used to store the collected historical data, alarm records and operation records.

[0029] Further, a remote monitoring center is also included, which is in remote communication connection with the data processing module.

[0030] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.

[0031] The above description of disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
