Problems solved by technology

[0003] At present, the main method for estimating the remaining driving range of electric vehicles is to construct a simple linear relationship between the battery SOC and the remaining driving range. In fact, the energy consumption of electric vehicles is greatly affected by factors such as driving style, driving road and road conditions, so only The remaining mileage converted by electricity is often quite different from the actual mileage
Moreover, inaccurate estimation of the remaining mileage often misleads the user's itinerary planning, so that car owners often worry that the existing power is not enough to reach the destination, resulting in "mileage anxiety"

Embodiment 1

[0091] The implementation of the present invention provides an electric vehicle residual renewal mileage estimation method, such as figure 1 As shown, the method includes:

[0092] S100: Get the remaining available electricity capacity of the battery in real time.

[0093] During the driving of electric vehicles, the vehicle terminal collects the remaining battery SOC information in real time, and reads the battery management system charged state through the CAN bus.

[0094] STATE CHARGE, SOC, refers to the ratio of the storage battery for a period of time or long-term resting capacity and its fully charged state, with a percentage of 0 ~ 1, when SOC = 0 When the battery discharge is complete, when SOC = 1 indicates that the battery is fully full. According to SOC information, the remaining electricity consumption of the battery can be calculated, using E remain Express.

[0095] S200: Depending on the road level, congestion degree of congestion and the driver's style of the driv...

Embodiment 2

[0152] Example embodiments provide an electric vehicle according to the present invention, the remaining range estimating means, such as image 3 As shown, the apparatus includes:

[0153] Available power acquisition module 10, a remaining available capacity of the battery acquired in real time.

[0154] Per mile power consumption acquisition module 20, according to the travel route of the road grade, the degree of congestion and driving style of the driver, to get the power consumption per mile.

[0155] Remaining range calculation module 30, according to the remaining available capacity of the battery and the power consumption per mile, the residual range is calculated.

[0156] The present invention integrated the driving style, the road level of the planning itinerary, and the situation of real-time congestion of the road conditions on the impact law of the trip energy consumption, quantitatively predicting the unit mileage in the driving process of electric vehicles. The prese...

Embodiment 3

[0193] The method according to embodiment 1 of the present specification, the above-described embodiment provides the business logic may be implemented by a computer program and recorded on a storage medium, the storage medium may be read and executed by a computer to achieve the effect according to an embodiment described in the present embodiment description. Accordingly, the present invention also provides for the electric vehicle remaining range estimated computer-readable storage medium comprising processor-executable instructions for storing a memory, to realize an electric vehicle including embodiments Example 1 while remaining continuously executed by the processor step mileage estimation method of driving.

[0194]The present invention integrated the driving style, the road level of the planning itinerary, and the situation of real-time congestion of the road conditions on the impact law of the trip energy consumption, quantitatively predicting the unit mileage in the dri...

Abstract

The invention discloses a method, device, storage medium and equipment for estimating the remaining mileage of an electric vehicle, belonging to the field of electric vehicles. The method includes: obtaining the remaining available power of the battery in real time; obtaining the power consumption per unit mile according to the road grade of the travel route, the degree of congestion, and the driving style of the driver; remaining mileage. The invention comprehensively analyzes the influence law of the driving style of the driver, the road grade of the planned itinerary and the real-time congestion degree of the road condition on the energy consumption of the itinerary, and quantitatively predicts the power consumption per unit mileage during the driving process of the electric vehicle. The present invention adopts the method for estimating the remaining mileage by integrating the information of people, vehicles and roads, and considers more comprehensive factors, so that the remaining mileage of the electric vehicle can be calculated more accurately, which helps to alleviate the user's mileage anxiety.

Description

Technical field [0001] The present invention relates to the field of electric vehicles, electric vehicles, and particularly to a remaining range estimation method, apparatus, and computer-readable storage media devices. Background technique [0002] The face of the energy crisis and environmental pollution problems have become more serious, with its low-power electric vehicles, the advantages of zero emissions are being widely used. The electric vehicle battery energy density is low, high cost, difficult to increase the lead to driving range, which is the main reason for restricting the promotion of electric vehicles. The remaining driving range of electric vehicles refers to the actual process of moving power is less than 100% of the driving range, accurate forecasts the remaining range of the vehicle to guide the user to travel premise. [0003] The larger the current the remaining range estimation method is mainly used in electric vehicle battery SOC construct and the remainin...
