Problems solved by technology

However, due to the different driving scenarios of the vehicle and the different operating conditions of the vehicle, the energy consumption of the vehicle will be different within the preset time interval, that is, the change of the cruising range of the vehicle within the preset time interval is also different. With the solution of the prior art, when the cruising range of the vehicle changes quickly / slowly, the display of the cruising range is still only performed to the user according to the preset time interval and the fixed step, so that the display of the cruising range of the vehicle instrument does not change. It cannot be adjusted according to the current operating conditions of the vehicle, and it is not convenient for users to know the actual mileage of the vehicle in a timely and accurate manner

Abstract

The invention provides a display mileage updating method and device of an electric vehicle and the vehicle, and the method comprises the steps: obtaining the current vehicle operation state and the current environment information of a vehicle when the change of the driving road condition is recognized; according to a preset reference energy consumption model, acquiring reference energy consumption of the vehicle under the current vehicle running state and the current environment information; calculating the mileage according to the reference energy consumption and the residual energy of the vehicle; and adjusting the updated display mileage according to a preset mileage change rule in the driving process of the current driving road condition according to the drivable mileage and the display mileage currently displayed by the vehicle-mounted instrument. According to the invention, the current display mileage of the vehicle is dynamically adjusted based on the actual travelable mileage of the vehicle, so that the adjusted display mileage change can accord with the current running state of the vehicle, accurate display mileage update can be provided for a user in time, and accurate endurance is realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a display mileage updating method, device and vehicle of an electric automobile. Background technique [0002] Due to the limited battery capacity of electric vehicles, how to prevent vehicles from being forced to stop due to insufficient power during driving is particularly important. Therefore, the cruising range of electric vehicles has become the most concerned issue for drivers. [0003] At present, when driving an electric vehicle, the driver usually knows the cruising range of the vehicle through the cruising range displayed on the vehicle instrument, so as to plan the driving route and the like. In the prior art, the cruising range of the vehicle meter is usually refreshed and displayed according to a preset refresh cycle and a fixed step size, so that the cruising range data of the vehicle meter can be displayed and changed according to a certain time interval and a...
