12V Anti-Pinch Electric Window Module (Self-Learning)

Overview

The EBX-2206 is the EBX family's dedicated 12 V anti-pinch window controller. Where a full BCM such as the EBX-2305 absorbs the window function into the wider body-control scope, the EBX-2206 is the right tier when the program wants the anti-pinch / self-learning / member-window-disable logic isolated on its own ECU — either to meet a regulator-driven anti-pinch certification scope cleanly, or to keep the door-harness pinch-detection loop close to the motor and away from the rest of the BCM I/O.

Electrically the module operates on a 9–16 VDC main feed with a 7–18 V CAN front-end (the wider bus-voltage tolerance keeps the CAN link alive through cranking sags and load-dumps). System-reset threshold sits at < 6 V, after which the controller re-initialises and the self-learnt travel-position data needs to be re-trained on the next ignition cycle. Quiescent current is ≤ 1.0 mA, in line with passenger-car parking-current targets. The build complies with GB/T 30512-2014 (Requirements for prohibited substances on automobiles) on materials, and EMC validation follows the customer's OEM EMC test-method profile (programme-specific profile reference shared on PPAP request).

Integrated functions

The EBX-2206 carries the eleven-function set typical of a passenger-vehicle anti-pinch window controller:

• Software housekeeping. Hard-real-time scheduler, self-diagnosis, fault-flag storage, CAN-bus management.
• Anti-pinch detection. Continuous torque / current monitoring on the up-direction stroke — the controller reverses the window the instant pinch is detected, in line with the typical regulator profile for anti-pinch certification.
• Step-loss suppression. Position-counter recovery logic that protects the self-learnt travel calibration when the motor skips counts under load.
• Window initialisation (self-learning). Position-end self-calibration cycle that records the upper and lower mechanical stops without an external setup tool — runs once after a battery disconnect / system reset, and per the program's housekeeping rules afterwards.
• Member-window-disable. Driver-side master switch that locks out the rear / passenger window switches (child-safety / passenger-locked operation).
• RKE remote up-down. Remote-keyless window up / down on the RKE channel, with the configurable retention window on the typical KEY-OFF profile.
• Thermal protection. Motor-driver thermal de-rating that protects the H-bridge on repeated stall-current cycles.
• Auto-up. One-touch auto-up to the upper stop, with the anti-pinch reverse-out always armed.
• Manual-up. Switch-held window up while the operator holds the switch.
• Auto-down. One-touch auto-down to the lower stop.
• Manual-down. Switch-held window down while the operator holds the switch.

Engineering details

The EBX-2206 occupies a 200 × 88.4 mm footprint (178.5 mm body width × 80 mm depth, 200 mm over the side mounting ears) with a 34.5 mm overall height. The harness interface is two mid-density sealed housings on the left and right edges of the housing — one connector typically lands the power / CAN / RKE channel and the other lands the motor drive / switch inputs / position-sense channel, so the door-loom and the body-loom are kept on opposite sides of the controller.

• Wide-range CAN front-end: 7 – 18 V bus-voltage tolerance keeps the controller talking through cranking sags and brown-outs, so the body network does not lose the window controller during start events
• System-reset threshold < 6 V: below this the controller re-initialises and RAM-resident state (including the self-learnt travel calibration) needs to be re-trained on the next ignition cycle
• Anti-pinch torque-detection with reverse-out arm, suitable for the regulator-driven anti-pinch certification scope on passenger-car programs
• Self-learning travel calibration: no external setup tool required; the controller runs the upper / lower-stop learn cycle after a battery disconnect or system reset and per the program's housekeeping rules
• Thermal protection on the motor-driver stage de-rates the H-bridge on repeated stall-current cycles — protects the controller and the motor on a stuck window
• Material compliance: GB/T 30512-2014 (restricted-substance requirements for automobiles); cosmetic surfaces free of burrs / scratches / deformation defects that would affect performance
• Dimensional discipline: free-tolerance dimensions per GB/T 1804-f, free-form geometric tolerance per GB/T 1184-H, un-marked dimensions per the 3D data set delivered with the customer release

Mechanical layout & connector field

Comparison with other Youlai window / BCM modules

The EBX family covers several patterns for the electric-window function group. The EBX-2206 is the dedicated 12 V anti-pinch + self-learning tier:

The EBX-2206 is the right choice for a 12 V passenger-vehicle program that wants anti-pinch / self-learning isolated on its own ECU (typical for regulator-driven anti-pinch certification scope). For a 24 V commercial-vehicle dedicated window + mirror + central-locking controller without anti-pinch, look at EBX-2315; for a BCM that absorbs the window function group, look at EBX-2305 or EBX-2169.

Manufacturing & testing

Built under IATF 16949 with APQP project planning and a PPAP package available for OEM programmes. Every unit is end-of-line functional-tested before packaging — CAN bus health across the 7–18 V range, quiescent current, the H-bridge motor drive, the anti-pinch torque-detect threshold, the self-learn travel-calibration cycle, the member-window-disable lock-out and the RKE up-down channel are all checked. Material compliance follows GB/T 30512-2014; EMC validation follows the OEM EMC test-method profile in our in-house lab.

How to ask
