Brake Control Systems TRIZ Cases

A generic brake calibration enables immediate braking after operating element replacement, then switches to verified element-specific data.

Pressure and temperature sensing across the brake caliper enables early fault diagnosis in railway vehicles, including driverless operation.

Multiple speed checks and rate-of-change criteria prevent false brake activation from transient sensor events, reducing delays and wasted operator time.

Alarm and brake thresholds shift with traction mode, improving collision warning timing on low-friction roads without excessive early alerts.

Multiple roof-mounted microphones analyze brake sound spectrum and vibration to estimate pad wear and issue timely safety warnings.

Wheel speed feedback adjusts shaft slip in open differential heavy-duty vehicles to curb uneven wheel spin and preserve traction.

Wheel speed changes at crawl speed reveal brake rotor wear, enabling onboard health checks and timely maintenance alerts.

Tyre tread deflection sensing updates the inverse tyre model in real time, improving heavy-duty wheel slip control on changing road surfaces.

An independent supplemental brake subsystem monitors primary brake status and adds wheel braking to maintain autonomous vehicle stability.

Cross-output control lets one output component drive both actuators after a failure, avoiding sudden power loss and improving stability.

Measures car-following safety by tracking distance, acceleration, and response timing across the full braking sequence, not just final spacing.

Measures actual brake effect during driving by applying a test current and comparing sensor feedback with expected response.

A switchable dual energy path lets one aircraft brake supply support both brakes after a failure, improving redundancy without extra backup hardware.

A particle filter estimates the tire friction curve from low-cost vehicle sensors, adapting in real time to changing road conditions.

Distributes driver braking demand between powertrain drag and wheel brakes to preserve familiar deceleration feel despite lower natural slowdown.

A switch-over controller adapts to y-connected or direct-cabled brake peripherals to suppress signal interference and reduce controller variants.

Adds speed-dependent friction and cornering stiffness to predict wet-road tire grip more accurately in real-time simulation.

By estimating brake temperature from absorbed energy during taxiing, selective brake actuation cuts carbon disc wear while preserving RTO capability.

Dual brake controllers use wheel speed signals from main and additional axles to improve fault detection without extra control units.

Using multiple tire models and tire-related sensor signals, this case quantifies road friction uncertainty for more reliable vehicle control.

Friction data lets ACC estimate secondary brake capacity and trigger braking earlier on low-grip roads, improving stability and reducing wear.

A physical model captures leading-wheel liquid removal to predict trailing-wheel adhesion and simulate rail braking approval tests more realistically.

Unique actuator IDs are checked against location-specific records to catch vehicle misinstallation before unsafe control signals occur.

Sensors verify coupling element positions and lock or release the tractor parking brake to prevent unsafe semi-trailer movement.

When steering fails during hands-free driving, a controlled brake jerk prompts two-handed takeover and helps prevent lane deviation.
