Passenger Side Parking Brake Controller PCBA – Electronic Handbrake Control with Motor Driver, LED Indicators & Safety Interlock for Driver Training Vehicles
No.YQQX038
- Dual Control Logic – Accepts inputs from both driver’s main handbrake switch and instructor’s passenger side switch (or foot pedal). Independent override: passenger switch can engage/disengage brake even when driver’s switch is inactive.
- High‑Current Motor Driver – Drives electric parking brake actuator (DC motor, 12V/24V, up to 10A peak). Supports bi‑directional operation (apply / release). Built‑in current sensing for stall detection (motor stops automatically when end‑stop reached).
- Safety Interlock – Prevents simultaneous opposite commands (e.g., driver releasing while passenger applying). Software prioritises passenger (instructor) command for emergency braking scenarios. Manual override key switch (optional) disables passenger control when not needed.
- LED Status Indicators – Brake applied (red), brake released (green), system fault / overload (yellow flashing). Optional audible buzzer for brake application warning (e.g., beep when passenger brake activated).
- Fault Protection – Over‑current shutdown (e.g., >12A for >1s), over‑temperature cut‑off (onboard NTC, >85°C), and reverse polarity protection on power input. Auto‑retry after thermal cooldown.
- Applications – Suitable for: driving school vehicles (passenger brake for instructor), dual‑control training cars, fleet driver assessment vehicles, adaptive driving aids for disability training, and government driving test cars. Works with electronic parking brake (EPB) systems and retrofit cable‑pull electric actuators.

Product Overview
The Passenger Side Parking Brake Controller PCBA is an electronic control module designed to add a secondary handbrake control on the passenger side (instructor or evaluator) in driver training vehicles. It interfaces with the vehicle’s existing electronic parking brake (EPB) actuator or a retrofitted electric pull actuator, allowing the passenger to apply or release the brake independently of the driver.
This PCBA prioritises passenger commands for safety (emergency braking), includes LED indicators for brake status, and protects the motor and wiring with over‑current and over‑temperature shutdown. It is ideal for driving schools, fleet training programs, and government licensing tests where an instructor needs a reliable, quick‑acting emergency brake.
