Multi-ratio transmission gearset architecture: BYDRecent Research Landscape

Mechanical power losses and torque interruptions during gear shifts reduce energy efficiency and driveability. Engineering specific gear ratios and transmission coupling mechanisms optimizes energy transfer between the motor and wheels.

What technical problems is BYD addressing in Multi-ratio transmission gearset architecture?

Inadequate powertrain energy distribution

(59)evidences

Suboptimal energy management between multiple power sources leads to excessive fuel consumption and parasitic losses. Resolving this improves overall system efficiency and extends driving range.

Inefficient torque distribution control

(51)evidences

Suboptimal power allocation between front and rear wheels leads to energy loss and reduced traction. Resolving this improves vehicle range and dynamic stability.

Excessive powertrain spatial footprint

(20)evidences

Spatial constraints and integration conflicts between the drive unit and vehicle chassis. Reducing the physical footprint allows for better weight distribution and increased passenger cabin space.

Excessive powertrain footprint

(18)evidences

Suboptimal power flow between the engine and wheels leads to excessive energy loss. Improving this distribution increases overall vehicle range and fuel economy.
