Problems solved by technology

[0002] Vehicle quality is an important parameter for vehicle operation. If the vehicle quality cannot be determined during vehicle driving, it will lead to poor control accuracy of the driving force or braking force of the vehicle, which may easily cause vehicle safety problems.
However, the current vehicle mass estimation method has relatively large errors.

Embodiment Construction

[0068] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0069] The vehicle quality estimation method provided by this application can be applied to such as figure 1 shown in the application environment. The application environment involves the whole vehicle controller of the vehicle. The current driving parameters of the vehicle, such as engine torque, slope, vehicle speed, gear position, etc., are input to the vehicle controller through CAN bus or hard wire. The vehicle controller determines the current estimated value of the vehicle mass through the current driving parameters of the vehicle.

Abstract

The invention relates to a whole vehicle mass estimation method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining current driving state information ofa vehicle, wherein the current driving state information of the vehicle includes a current vehicle speed, a current accelerator pedal opening degree, a current brake pedal opening degree and a currentslope; when a preset triggering condition of whole vehicle mass estimation is met based on the current driving state information of the vehicle, acquiring current driving parameters of the vehicle; and determining a current vehicle mass estimated value according to the current driving parameters of the vehicle. By adopting the method, an error of whole vehicle mass estimation can be reduced.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a method, device, electronic equipment and storage medium for estimating the mass of a vehicle. Background technique [0002] Vehicle quality is an important parameter for vehicle operation. If the vehicle quality cannot be determined during vehicle driving, it will lead to poor control accuracy of the driving force or braking force of the vehicle, which will easily cause vehicle safety problems. However, the current vehicle quality estimation method has relatively large errors. Contents of the invention [0003] Based on this, it is necessary to provide a vehicle mass estimation method, device, electronic equipment and storage medium for the above technical problems. [0004] A method for estimating the mass of a vehicle, comprising: [0005] Obtain the current driving state information of the vehicle, the current driving state information of the vehicle includes:...
