Abstract

The present invention relates to a method for switching intelligent energy-saving driving modes for hybrid vehicles. The intelligent cockpit controller (HMI) interface is designed to input the current fuel price per liter and the current price per kilowatt-hour. The intelligent cockpit controller determines the current vehicle remaining battery power and the remaining fuel in the tank based on the input data and in combination with the CAN signal input from the vehicle controller and the fuel resistance signal input from the fuel pump. Simultaneously, the intelligent cockpit controller detects the vehicle's current driving conditions through the GPS and high-precision map integrated into the intelligent cockpit controller. Based on the current energy cost and the current driving conditions, a comprehensive calculation is performed to determine the most economical driving mode for the current driving situation. This conclusion is transmitted to the vehicle controller in the form of a CAN signal, switching to the target driving mode, and simultaneously notifying the driver of the current driving mode status. This improves the human-computer interaction experience of vehicle driving, enhances the energy-saving potential of hybrid vehicles, and improves the intelligent driving performance of hybrid vehicles.
