Description

Intelligent vehicle energy consumption management method and system Technical Field The invention relates to the technical field of intelligent vehicle energy management, in particular to an intelligent vehicle energy consumption management method and system. Background When the battery power or the fuel oil is low, the driver cannot accurately judge whether the residual energy reaches a destination (such as a home, a charging station and a gas station) or not, and if the vehicle breaks down due to energy consumption, the vehicle is prone to bringing about safety risks. In the prior art, the vehicle-mounted endurance-related function generally only carries out rough estimation on the remaining endurance mileage based on historical average energy consumption data, dynamic influence factors in the running process are not fully considered, such as actual road conditions, environmental factors, dynamically adjusted running paths and the like, the estimation result has larger deviation from the actual endurance, and the reference value is limited. And when the endurance mileage is close to or lower than the distance to the destination, only a low-energy warning is sent, the driver can only passively try to reduce the speed of the vehicle or close the air conditioner through subjective experience, so that the energy consumption is saved, the scientific energy consumption calculation support is lacked, the energy saving effect is difficult to ensure, the driving comfort is reduced, and the driving experience of the user is influenced.
