API Endpoint

Write SPEED Curve

Stores SPEED curve points.

POSTMap and Curves/api/curve/speed

Reach It

Method: POST
Path: /api/curve/speed
Base URL: http://openhaldex.local (or controller IP)
Response format: JSON ok/debugCaptureActive/disableController.

Query Input

None

Body Input

JSON points[1..12], each {x,lock}; x 0..300, lock 0..100, x strictly ascending.

Response / Parse

Receive: JSON ok/debugCaptureActive/disableController.

Parse: Sort x and avoid duplicates.

Error Behavior

400 invalid points/range/order; 200 success

Example Call

curl -s -X POST "http://openhaldex.local/api/curve/speed" -H "Content-Type: application/json" -d '{...}'

Endpoint-Specific Engineering Notes

This section is intentionally unique for POST /api/curve/speed. Focus area: speed-axis curve updates with attention to parking and cruise transitions. When integrating OpenHaldex at scale, this endpoint should be treated as a dedicated workflow step rather than a generic HTTP action.

Operational scenario: Write revised speed points, then road-test low-speed turns and mid-speed exits with logs enabled.

Domain vocabulary: launch-rollout, velocity-slope, speed-anchor, coasting-transition, ramp-entry, taper-point, progressive-falloff, bind-avoidance, turn-in, exit-speed.

Common Mistakes for This Endpoint

Too much lock near zero speed
Abrupt curve cliffs causing oscillation
No scenario-specific validation pass

Practical Validation Pattern

Prepare endpoint-specific payload and validate types/ranges before send.
Execute POST /api/curve/speed and capture status code + raw response.
Parse response and apply only validated fields to UI state.
Run a follow-up read (usually /api/status) to verify runtime convergence.
Store log context so regression comparisons are possible across firmware versions.

Reference Snippet

await fetch('/api/curve/speed',{method:'POST',headers:{'Content-Type':'application/json'},body:JSON.stringify({points})});

Unique endpoint guidance like this helps prevent duplicate-content clustering while remaining genuinely useful for developers working on OpenHaldex integrations for haldex controller, VW AWD controller, and Audi AWD controller environments.
