Continuously variable transmission ratio control: BYDRecent Research Landscape

Mechanical power loss and packaging constraints increase vehicle energy consumption. This architecture integrates the drive unit and transmission to optimize torque transfer efficiency.

What technical problems is BYD addressing in Continuously variable transmission ratio control?

Inefficient power flow management

(39)evidences

Disruptions in power flow during ratio transitions or mode switching in hybrid systems. Eliminating these fluctuations ensures smooth acceleration and prevents mechanical shock.

Unintended vehicle movement during standstill

(38)evidences

Mechanical instability during stationary periods in electric drivetrains. Preventing uncontrolled movement ensures safety and regulatory compliance.

Inefficient torque distribution across axles

(34)evidences

Mechanical losses and power imbalances between axles in multi-wheel drive configurations. Optimizing this prevents energy waste and improves traction stability across varying terrain.

Inefficient power flow distribution

(32)evidences

Suboptimal coordination between multiple power sources leads to excessive fuel consumption and energy loss. Resolving this improves overall system efficiency and extends vehicle range.

Chassis integration space constraints

(28)evidences

Mechanical stress and vibration transfer between the powertrain and vehicle chassis. Improving structural cohesion reduces noise, vibration, and harshness while increasing vehicle durability.
