Power distribution control principles for a two-axle hybrid passenger car

Distribution of torques on the driving wheels of a car is the basis of its energy efficiency, determines its tractiondynamic and economic characteristics. Compared with a single-flow mechanical transmission, multi-flow hybrid transmissions allow more flexible control of power distribution. Modern hybrids of the P0 + P3 + P4 architecture have this capability in full. In this regard, their example is used to compare possible alternative control strategies for thermal and electric engines.
