# Industrial Specification: Steering Wheel/Joystick

## 1. Technical Definition
Primary manual control interface for vehicle directional guidance

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 Nm torque, 0-360° continuous rotation, 0-100 mm linear displacement (joystick variant)**. Failure boundary: **Torque &gt; 7.5 Nm causes plastic deformation in steering column splines; angular displacement &gt; 450° shears clock spring ribbon cable; linear force &gt; 150 N fractures joystick gimbal mechanism**, Mechanism: **Yield strength exceedance in AISI 1045 steel splines (σ_y = 530 MPa); fatigue failure in copper alloy ribbon cables (N_f &lt; 10^5 cycles at ε_a = 0.3%); stress concentration at gimbal pivot points (K_t = 3.2)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrostatic discharge (ESD) &gt; 15 kV to Hall effect sensor ICs | 8 | Sensor IC latch-up causing permanent 0° position signal output | TVS diodes (SMBJ15CA) on all sensor power rails with 1.5 pF parasitic capacitance limit |
| Polyurethane foam degradation under 85°C/85% RH for &gt;1000 hours | 8 | Foam compression set &gt;40% causing hand position detection failure | Closed-cell EPDM foam with carbon black filler (ASTM D1056 Grade 2C1) |
