Hybrid Vehicles TRIZ Cases

A compact hybrid drivetrain uses shared transmission paths and selector actuators to switch thermal, electric, and hybrid torque modes.

Pre-reducing motor torque and slipping the clutch lets a hybrid start the engine with less deceleration during mode switching.

Engine-off standby and rollout modes use stored battery energy to drive accessories or axles, cutting response time and fuel use.

Route-segment power prediction and SoE reference trajectories help hybrid vehicles balance electric and combustion use with low control-unit load.

Switchable stator windings and adjustable magnetic flux keep a motor-generator efficient across wide RPM and torque changes.

Driving force is reduced when low-emission battery power is scarce, prompting greener charging while limiting excess power use.

Selective clutch engagement lets one motor switch between battery charging and pump drive, improving power distribution efficiency in electrified vehicles.

An electronically controlled positive clutch replaces bulky friction clutches to smooth hybrid launch, shifting, engine starts, and mode transitions.

A nested generator-within-flywheel layout cuts hybrid powertrain width and volume while preserving motor, engine, and transmission functions.

Topography-based path planning sets segment SOC targets and regenerative downhill modes to keep hybrid battery charge stable across a route.

Torque-limited engine start-up with surplus urea dosing heats the hybrid SCR quickly, cutting cold-start NOx without oversized hardware.

Closed-loop ISG and engine control stabilizes the DC bus after battery failure, allowing the traction motor to keep driving safely.

A compact flywheel-side differential layout shortens half-shaft length differences to reduce driveline noise, vibration, and handling imbalance.

An upstream switching dog clutch separates engine drive from the transmission path, enabling smoother EV mode changes with lower energy loss.

During gear changes, electrical torque transfer between two motors maintains wheel traction, reduces driveline load, and improves comfort.

A single housing for the motor, generator, reduction gear, and engine drive path suppresses resonance, cuts size, and reduces torsional vibration.

Coordinated motor torque control matches output shaft speed during disconnect shifts, enabling smoother low-range engagement without shift bumps.

AI converts charging, driving, and parking habits into a battery management score that predicts lifespan and flags abnormal behavior.

Different execution rates for active and inactive vehicle subsystems cut hybrid control processor overload without hurting drivability.

A parallel hybrid powertrain combines an engine, motor/generator, and transmission to enable silent drive, battery charging, and full-power operation.

An engine-integrated motor-generator layout removes the transmission and differential to cut hybrid cost, energy loss, and emissions.

Magnetic dust collection in the torsion damper fluid path keeps wear particles away from hybrid motors and transmissions, improving durability and fuel economy.

Differential torque at the two steering wheels improves three-wheel cornering stability and agility using speed, handlebar angle, and rider torque.

Positive-pressure oil fed through an axial conduit lubricates planetary pinion bearings while reducing sealing losses in hybrid transmissions.

Parallel motor-generator placement shortens the hybrid transmission, avoids clutch-driven layout limits, and reduces self-load.

Pre-stored safety torque limits let the controller handle power source failures by matching torque to driving risk and avoiding abrupt torque loss.

Using a grid box to absorb extra generator power raises exhaust temperature for purifier cleaning without added batteries, muffler resistors, or weight.

Temperature-based mode switching adjusts engine load and injection timing during hybrid cold starts to cut particulate emissions and fuel loss.

When a target gear is unavailable, the vehicle switches drive mode and selects an available gear to maintain power and prevent stalling.

When wheel slip is detected on low-adhesion roads, the vehicle shifts from series mode to idle electric four-wheel drive to improve escape performance.

Oil scraped by a rotating body is routed through a partition-wall passage to a shaft bearing, avoiding pump drive losses in vehicle transmissions.

Temperature-based battery reserve thresholds let a hybrid stay in pure electric mode longer while keeping enough energy for vehicle demand.

Lowering the engine speed target during downshift deceleration cuts first-motor power use and helps prevent battery undercharging.

Supplemental torque based on speed and performance class improves hill starts, towing launch feel, and traction without added hardware.

Placing the electric machine below the swingarm and linking it to the secondary transmission improves stability, electric drive, and regenerative control.

A coaxial shift drum and cam layout lets one drive source switch two engagement devices, cutting hybrid drive size and actuator complexity.

Actuator-guided shifter pathways add tactile feedback in EVs while combining gear selection and drive mode switching in one control assembly.

Axial rotor movement uses magnetic force to preload meshing gears, cutting backlash-driven gear rattle in vehicle drive paths.
