Vehicle energy management method and device

Abstract

The invention provides a vehicle energy management method and device. The method comprises the following steps: screening at least one current possible travel route of a user from historical driving data of a vehicle based on current time information and position information; comparing the current driving route of the user with the route characteristics of the current possible travel route, and selecting a target route according to the matching degree; and constructing a vehicle speed model of the vehicle based on the target route, and optimizing the energy distribution of the vehicle on the target route according to the strong correlation between the vehicle speed model and the power consumption.

Description

technical field [0001] The present invention relates to the field of vehicle management, and in particular, to a method and device for energy management of a vehicle. Background technique [0002] With the vigorous development of the country's green travel and intelligent network technology, the deep integration of electric vehicle technology and intelligent network technology has gradually strengthened. From the perspective of green economic travel, vehicle energy optimization control technology has become particularly important. In the prior art, the related technical solutions have been upgraded from the rule-based optimization control method to the global predictive planning control of energy, mostly through effective energy prediction methods and advanced algorithm design, so as to achieve better global energy prediction. and optimal allocation. [0003] However, a common problem in the prior art is that the current vehicle energy management control method requires the...

Problems solved by technology

[0003] However, a common problem in the existing technology is that the current vehicle energy management control method requires the driver to turn on the route setting of the navigation, which is equivalent to knowing the planned and determined route in advance, such as setting the destination A to the starting point in advance The route of B, so as to perform energy prediction and optimal control based on the determined route, plan the optimal driving mode of the future route, and perform global optimal distribution control

However, some users habitually do not turn on the navigation function for familiar roads, or cannot use the route setting and positioning function of the navigation for other objective reasons. They can only turn off the energy predictive control function, which cannot play a role in the energy consumption of the vehicle during driving. optimal management
