AI Technical Summary

Technical Problem

The energy management and control strategies of existing new energy vehicles are solidified during actual driving and are inconsistent with the user's driving road conditions, especially in long downhill areas in mountainous areas and plateaus, resulting in energy waste.

Method used

By obtaining the current operating status and road spectrum data of the vehicle, predict whether the road ahead is downhill and introduces a downhill mode. When the user selects to enter the downhill mode, the vehicle's acceleration torque request value is adjusted according to the preset downhill mode energy management control method to achieve dynamic compensation for energy management.

Benefits of technology

It effectively improves the vehicle's cruising range and reduces fuel consumption, makes energy management and control suitable for the current road, and reduces energy waste.

Abstract

The invention provides a vehicle energy management control method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a current operation state of a vehicle; determining corresponding road spectrum data according to the current running state of the vehicle; determining whether to enter a downhill mode according to the current running state of the vehicle and the corresponding road spectrum data; when the downhill mode is met, a user is prompted to perform mode selection; and when the user selects to enter the downhill mode, an acceleration torque request value of the vehicle is adjusted according to a preset energy management control method of the downhill mode. Whether the front road is downhill or not is predicted according to the current running state and the road spectrum data of the vehicle, the downhill mode is introduced, when the user selects to enter the downhill mode, energy management dynamic compensation is conducted on the vehicle through the preset energy management control method of the downhill mode, energy management control is made to be matched with the current road, and the user experience is improved. The endurance of the whole vehicle is effectively improved; and the oil consumption is reduced.
