Electrical Steering TRIZ Cases

A torque differential compensation value adjusts assist current based on steering speed to maintain steering feel.

Torque estimating apparatus calculates self-aligning torque using vehicle speed and yaw rate data to correct steering assist force.

Filtering motor rotation speed signals reduces steering wheel vibrations and noise while maintaining system responsiveness.

A sensor detects acoustic vibrations during steering angle changes to identify excessive friction in the steering gear.

A steering controller adjusts compensation values during mode switching to stabilize motor current commands.

A disk rotor and stator arrangement provides direct electromagnetic force transmission for vehicle steering.

A vehicular self-diagnosis device calculates maximum divergence amounts from multiple sensor offset components to detect inconsistencies.

A motor inertia compensation module generates commands to counteract rotational mass effects in electric power steering systems.

A rotary force diagnostic tool measures applied handle force and angular position simultaneously using integrated sensors.

A steering system shifts its neutral position to match the lane curvature.

Non-conductive separating sections on the printed circuit board electrically isolate independent subsystems, preventing failures from conductive particles.

Segments electronic arrangements around the motor housing to reduce installation space and eliminate separate ECUs.

Auxiliary control unit actuates safety unit to disconnect electric motor, preventing steering resistance torques during main control failure.
