Power development for rapid start in full-hybrid drives with optimized traction control

摘要

A launch control system for a hybrid vehicle is described. The system includes overcharging an electrical energy storage unit of the hybrid vehicle, operating an internal combustion engine at an increased power level, and operating an electric motor at an increased power level with the overcharged electrical energy storage unit. The transmission during the launch is configured to connect the electric motor and the internal combustion engine to a drivetrain of the hybrid vehicle, and to selectively slip friction clutches to store energy and release it for the launch.
