Background
With the rapid development of economy, the quantity of vehicles on roads is increasing. Different vehicle types such as cars and trucks have different load weights. If the actual load weight exceeds the factory specified maximum load weight of the vehicle, great potential safety hazards exist, mainly manifested in that the braking distance is too long, the tire shock absorption pressure is too large, the chassis bearing is limited, and the like, and permanent deformation of metal parts is easily caused. This is a great hazard to the driving safety and the vehicle itself.
However, at present, neither cars nor trucks on the market have the load weight detection function and the report notification function of the cars themselves, and only rely on an external fixation method to call a total weight, or perform visual inspection through human experience. The method has the defects of inconvenience and poor accuracy. With the intelligent development of the vehicle-mounted terminal with the vehicle-mounted navigation function, how to realize vehicle-mounted weight early warning based on the vehicle-mounted terminal becomes a topic with great prospect.

Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The vehicle-mounted weight early warning method and system, the storage medium and the vehicle-mounted terminal can acquire the vehicle-mounted weight in real time, and inform the actual load weight to the driver in real time, so that the driver can know the current vehicle condition and make reasonable judgment and driving behaviors. If the actual load weight is within the safe load range, normal driving is prompted; when the actual load weight is close to the factory maximum load weight, the driving is prompted to be slow and stable; the actual load weight exceeds the maximum load weight, warning of the need for low speed travel or reduction of the load to a safe value.
As shown in fig. 1, in an embodiment, the vehicle-mounted weight early warning method of the present invention includes the following steps:
and step S1, acquiring pressure values acquired by a preset number of pressure sensing devices positioned on the frame.
Specifically, a preset number of pressure sensing devices are arranged on a frame of the vehicle to acquire pressure values at various mounting positions. Preferably, four pressure sensing devices are employed, one above each of the four tires of the vehicle and in front of the vehicle shock absorber and the vehicle shock spring. Due to the damping difference of each car factory, the pressure sensing device needs to calibrate the acquired numerical value according to the damping calibration parameters, and finally outputs the calibrated pressure numerical value.
In an embodiment of the invention, the pressure sensing device directly transmits the pressure value to the vehicle-mounted terminal in a wired or wireless manner.
In another embodiment of the present invention, the pressure sensing device first sends the pressure value to an Electronic Control Unit (ECU) of the vehicle, and the ECU sends the pressure value to the vehicle-mounted terminal through a CAN bus.
And step S2, calculating the actual load weight of the vehicle based on the pressure value.
Specifically, for the received preset number of pressure values, the vehicle-mounted terminal obtains the actual load weight of the vehicle by summing and calculating an average value. I.e. the actual load weight is the average of a preset number of pressure values. Therefore, the more evenly the pressure sensing devices are distributed, the more accurate the resulting actual payload weight.
And step S3, when the actual load weight is larger than the preset maximum load weight, giving out an early warning.
Specifically, the vehicle-mounted terminal compares the actual load weight with a preset maximum load weight corresponding to the vehicle. If the actual load weight is less than or equal to the preset maximum load weight, the vehicle can run normally and safely; and if the actual load weight is larger than the preset maximum load weight, indicating that the vehicle is overloaded currently, and continuing to run so as to have potential safety hazards. At the moment, the vehicle-mounted terminal can give out early warning in a voice or text display mode so as to remind a driver to adopt corresponding measures in time.
Preferably, the vehicle-mounted terminal can display the pressure values at the installation positions, the actual load weight and the preset maximum load weight, which are acquired by the pressure sensing devices, through a display screen so as to be viewed by a driver in real time.
In an embodiment of the present invention, the vehicle-mounted weight warning method further includes locally counting the historical actual load weight of the vehicle. Specifically, the vehicle-mounted terminal counts the historical actual load weight within a period of time and displays the historical actual load weight to the user in a chart mode.
In another embodiment of the present invention, the vehicle-mounted weight early warning method further includes sending the historical actual load weight to a cloud server, so that the cloud server counts the historical actual load weight of the vehicle. Specifically, the vehicle-mounted terminal sends the obtained actual load weight to a cloud server, the cloud server counts historical actual load weight within a period of time, and the historical actual load weight is displayed on the vehicle-mounted terminal in a chart mode.
