Reliable current monitoring for electric parking brakes

Electric parking brakes are safety-relevant systems that play a crucial role in vehicles and must guarantee absolute reliability at all times. The driver must be able to trust that the braking system will hold the vehicle safely even on steep slopes. To ensure the long-term functionality and safety of these systems, continuous monitoring of the current profile during actuation is essential.

Monitoring the current profile via shunt

A shunt monitors the current consumption of the actuator when the brake is applied and released by reporting the voltage signal back to the control unit. This uses a fixed current profile that the motor must adhere to. If the motor is blocked, the control unit would assume without feedback that the brakes are applied, although only the motor is blocked. Accurate feedback on the motor current is therefore required over the entire service life of the vehicle.

The main requirement for the current sensor is the lowest possible total deviation over its service life, i.e. it must always deliver the same signal over its entire service life with identical current profiles. The second key requirement is a high pulse load capacity, so that the shunt can dissipate the heat generated in the hotspot well and thus ensure only minimal self-heating.

Components from the ISA-PLAN®-series meet these requirements and are ideally suited for these applications due to their high precision and thermal stability.
