Abstract

An electronically controlled pneumatic parking brake system (305) for a vehicle (100) is described. The system comprises a controller (300), an air supply source (230), and two electropneumatic valves (210, 220). The controller (300) is designed to generate electronic brake signals for activating or deactivating the parking brake (360). The electropneumatic valves (210, 220), connected to the controller (300) and the air supply source (230), function by releasing or applying the brake based on the received signals. If a valve malfunction is detected, the controller (300) controls a Pulse Width Modulation (PWM) signal generator (301) to generate a PWM signal, which provides heating to the malfunctioning valves (210, 220), aiming to restore their function by melting ice in the valves (210, 220).
