Smart Motor Technology

LIN BusCommunication

以實車匯流排訊號驗證,打造原廠相容智慧馬達。

Modern vehicles use LIN (Local Interconnect Network) to control door electronics. In a LIN-controlled window system, the smart motor acts as a network node, receiving commands and reporting status. Supported control and anti-pinch functions depend on the application. Han Yale analyzes authentic bus signals from real vehicles and builds smart motors that speak the same language as the original.

How LIN works

One wire, one master, every message on schedule.

LIN is a low-cost serial network for body electronics. A master node, such as the BCM or door module, sends each frame header. The scheduled publisher then supplies the response data. This scheduled communication gives each message a defined place in the network cycle.

Why it matters for replacement

A LIN motor has to fit the network, not just the door.

If the replacement motor answers the wrong frame, uses the wrong timing or reports unexpected status, the vehicle may log a fault, disable one-touch operation or prevent window movement. Our development and validation focus on four areas.

專為採用 LIN 架構的車輛設計

Vehicles equipped with LIN-controlled window motors require a compatible network node rather than a conventional DC motor. Han Yale's in-house motor electronics speak the vehicle's native protocol, supporting replacement applications that require matched electronics and firmware.

原廠協定匹配

Bus signals validated on real vehicles ensure correct communication with the Body Control Module (BCM). Connector, protocol, firmware and initialization requirements are checked for each application.

Application-Specific Anti-Pinch Control

On applicable configurations, Hall sensing and motor-load monitoring support obstruction detection and window reversal. Response characteristics and applicable safety requirements are defined and validated for the selected part number and vehicle system.

雙向診斷

Two-way communication reports motor thermal status, overcurrent, stall and voltage deviations back to the BCM, supporting troubleshooting through compatible diagnostic tools, subject to vehicle and tool support.

LIN smart motor vs conventional motor

Where the intelligence lives.

A conventional motor only turns when it receives power. A LIN smart motor carries its own electronics and works as part of the vehicle network.

How we validate

From real-vehicle signals to a matched smart motor.

Our process combines vehicle signal capture, firmware development, bench testing and validation on the applicable vehicle.

  4. 04Bench & rig testingCheck travel, one-touch, anti-pinch and fault reporting on the door rig.
  5. 05Real-vehicle validationVerify initialization, supported functions and diagnostic behavior on the applicable vehicle.
在進行採購之前

LIN motor questions.

How do I know if a vehicle uses a LIN window motor?

A common LIN motor configuration uses power, ground and a LIN signal connection. Connector appearance or wire count alone does not confirm the architecture. Send us the OE part number and we will confirm the architecture.

Can a conventional motor replace a LIN motor?

No. Without the correct LIN node the vehicle cannot command the motor, and it will usually log a fault. The replacement must carry matching electronics and firmware.

Is initialization required after installation?

Some vehicles require a window initialization or relearn after replacement, following the vehicle's service procedure. We confirm the procedure for each application during validation.

Can you develop a LIN motor that is not yet in your range?

Yes. With access to the vehicle or an original motor sample, our Taiwan engineering team can capture the bus signals and evaluate the program for development.
