Experimental Study on Semi-Automatic Parking Brake System for Cost-Effective Passenger Vehicles

Abstract

The Semi-Automatic Parking Brake (SAPB) has been developed to enhance safety, reliability and convenience by replacing the conventional manual handbrake with an electronically controlled system. It integrates a microcontroller, actuator motor, sensors, and a control unit to function in a coordinated manner. When the vehicle ignition is switched on, the brake is released automatically and when the ignition is turned off, the brake engages and locks securely. The system was evaluated under various operating conditions, including level roads, uphill and downhill gradients, as well as emergency scenarios such as power loss or sensor malfunction. Test results demonstrated rapid operation, sufficient braking force and consistent performance across all conditions. Even under challenging circumstances, the SAPB maintained stability and ensured vehicle safety. Compared with traditional handbrakes, the system provides greater automation, improved precision, and higher dependability, making it a suitable solution for cost-effective passenger vehicles.
