Electric automobile and double-endurance mileage display control method thereof

Abstract

The invention discloses an electric automobile and a double-endurance mileage display control method thereof.The double-endurance mileage display control method of the electric automobile comprises the steps that first average energy consumption of the electric automobile in a first driving mileage is obtained based on the preset first driving mileage; acquiring second average energy consumption of the electric vehicle in a second driving mileage based on a preset second driving mileage, acquiring residual energy of the electric vehicle, and calculating a first endurance mileage according to the residual energy of the electric vehicle and the first average energy consumption, and calculating a second endurance mileage according to the residual energy of the electric vehicle and the second average energy consumption, and displaying the first endurance mileage and the second endurance mileage. Therefore, the second endurance mileage enables a driver to visually and accurately understand the real endurance mileage of the vehicle in the current driving scene, and meanwhile, the driver can clearly evaluate the endurance ability of the vehicle by referring to the first endurance mileage, so that the endurance mileage prediction reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of complete vehicle control of electric vehicles, in particular to an electric vehicle and a method for displaying and controlling its dual cruising range. Background technique [0002] The cruising range refers to the mileage that the energy currently possessed by the vehicle can maintain the vehicle to continue driving. In the vehicle status information, the cruising range can provide a reference for the driver's driving behavior decision-making. In electric vehicles, due to the fact that the battery energy is smaller than the total energy of fuel vehicles, and electric vehicles have less charging facilities, long charging time, and a wide range of energy consumption changes, accurate cruising range predictions are of great significance to drivers. . [0003] The current cruising range of an electric vehicle is usually calculated based on the battery energy storage state and the average energy consumptio...

AI Technical Summary

Problems solved by technology

[0003] The cruising range of current electric vehicles is usually calculated based on the battery energy storage status and the average energy consumption level of the vehicle. Among them, the average energy consumption is mostly calculated based on the data of long-term accumulated driving conditions, because the final display The value of the cruising range of the electric vehicle balances various situations, resulting in a large difference from the actual mileage, which leads to the low reliability of the prediction of the cruising range of the electric vehicle
