Abstract

The invention discloses a 5G technology-based electric vehicle ramp driving speed optimization method. The method comprises the following steps of S1, obtaining ramp data and driving data in a vehicle driving process; s2, calculating the energy consumption of the vehicle according to the ramp data and the driving data; and S3, calculating the optimal driving force and the vehicle speed of the vehicle passing through the ramp, so that the energy consumption accumulated value of the vehicle passing through the ramp within the preset time period is the lowest. The ramp data is acquired in real time based on the 5G Internet of Things technology, and the real-time speed and driving force of the vehicle are optimized by taking the lowest energy consumption of the vehicle passing through the ramp within the predetermined time period as the target function, so that the energy consumption of the vehicle passing through the ramp is reduced; and meanwhile, the phenomena of start-stop, idling, rapid deceleration, rapid acceleration and the like of the electric vehicle on a crossing ramp are reduced, so that the vehicle passing efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of electric vehicle energy consumption optimization, and in particular relates to a 5G technology-based method for optimizing the driving speed of electric vehicles on slopes. Background technique

[0002] Since environmental and energy issues have been concerned, the economy of automobiles has always been a research focus at home and abroad. The economy of a car is not only related to the performance of the vehicle itself, but also affected by the driving road and working conditions. Therefore, in recent years, some scholars have studied predictive cruise control considering road slope information. For heavy-duty trucks on roads with large slope changes and frequent road sections, the economical improvement effect is very obvious. Daimler Chrysler is based on the traditional adaptive cruise system, according to GPS navigation, combined with 3D digital maps, obtains the information of the slope of the road ...
