Vehicle Sub-Unit Features TRIZ Cases

Precomputed lookup-table compensation and ECU fault sharing cut back-EMF torque ripple and keep steering output stable after failures.

A protection plate between the cooling pipe and electrical device enables impact protection without blocking heat dissipation in a battery pack.

A deformable, length-adjustable grommet fits different vehicle layouts with one design, cutting mold and development costs while maintaining rigidity.

Uneven piston force distribution under critical brake conditions cuts disc brake noise and vibration while preserving requested braking force.

Short-circuiting steer-by-wire motor terminals when the vehicle is off creates counter EMF that prevents sudden steering wheel rotation and driver injury.

Recognized road signs are converted to region-applicable formats so drivers can follow local rules and vehicle controls across unfamiliar borders.

Crossed ribs in an integrally molded front side body cut part count and weight while dispersing crash loads to preserve robustness.

A removable shaft fixing member locks the steering shaft at neutral during transport, cutting alignment steps and assembly cost.

Actuator output limits that vary with damper speed are built into damping-force control, enabling faster target force distribution in vehicles.

A three-stage telescoping steering column extends wheel travel to about 170 mm, enabling full retraction into the vehicle body for autonomous modes.

A riser cavity in the brake hydraulic block collects gas bubbles from brake fluid, cutting noise and pressure pulsations without extra parts.

Pump drive frequency is shifted outside resonance when cabin background noise is low, balancing faster battery heating with less vehicle noise.

Navigation gyro data is merged with wheel speed sensing to improve vehicle body state estimation and variable shock absorber control.

A priority queue ranks upcoming road situations so suspension control avoids overlapping actions, improving ride comfort and steering stability.

Feedforward brake control corrects torque factor drift from pad bushing and seasonal friction changes to keep hydraulic brake force consistent.

Correcting wheel-speed slip estimates with longitudinal acceleration and tire characteristics improves vehicle body motion estimation on varying roads.

Point-cloud checks on distance and angle verify radar-LiDAR object matches before fusion, improving detection reliability in vehicles.

A platform server brokers paid content for vehicle exterior displays, simplifying transactions while enabling user interaction and revenue sharing.

PWM shifts electric pump frequency outside resonance when background noise is low, cutting battery-heating noise while maintaining thermal management.

Blending hydraulic braking with requested drive force smooths deceleration, expanding comfortable braking beyond rigid hydraulic-only control.

A rotatable tube support keeps friction uniform between steering column tubes, reducing telescoping noise, vibration, and shake.

Multiple motion constraints, including a nonzero minimum speed, help autonomous vehicles avoid obstacles and keep moving in complex environments.

Segmented hydraulic block modules improve brake component integration, reservoir routing, and screw-drive pressure generation in power braking.

Position-aware circuit guidance links external track data with onboard control to help drivers enter circuit mode and receive real-time driving support.

Compressed air actuation and force or torque sensing detect sticky parking brake release faults early, helping avoid towing and maintenance costs.

Sensors and an integrated controller block unsafe footrest and leg-rest motions to prevent seat collisions, part damage, and passenger injury.

A unitized actuator and friction brake save mounting space while keeping wheel braking available when actuator energization stops.

Injection-molded integration of the rotary unit and detection structure cuts steering assembly complexity and blocks moisture ingress.

Sensors switch among pre-stored secondary path models to keep vehicle noise cancellation stable as temperature, humidity, and occupancy change.

A solenoid-driven plunger unlocks a doorless fuel cap only when the vehicle is stationary, removing key use during refueling.

GPS-based correction adjusts wheel-speed display by speed range to keep indicated vehicle speed accurate and within legal tolerance.

Entertainment content is adjusted to vehicle speed and congestion so occupants stay engaged without compromising driving stability.

An annular rear end module and connection member create a closed-section load path that reduces load concentration and improves rear-body rigidity.

Temperature-based stepper motor torque control keeps HUD mirrors aligned in cold starts while avoiding excess audible noise.
