Multicraft technology is revolutionizing keyless vehicle entry, making it more accurate, secure and reliable. Known as “Passive Door Entry,” the method works when a key fob is within a certain distance of the vehicle, but the owner need merely touch or press a button or access point to unlock the car, rather than using a traditional key and lock. This technology has been in use in vehicles produced in the last five years to a decade, but has seen issues in reliability and even false openings.
In technical terms, our PE door handle utilizes the Multicraft Capacitive Touch Technology (MCTT) that detects when a person touches the door handle and sends an output signal to the car Body Control Module.
The door handle with MCTT can be activated by hand or hand with gloves. MCTT has an adaptive baseline features which makes it immune to environmental variables such as water, snow, dust, oil, etc.—a problem in some other companies’ iterations of Passive Door Entry that undermines the reliability of the lock.
This graph illustrates the adaptive baselines feature. Once a hand or hand with gloves touches copper pad at Finger Touch A (Figure 2), the MCTT adapts to the environment and provides necessary output to BCM (Body Control Module) which securely lock the car door. This technology will also prevent false reading that will avoid unnecessary power consumption. The same technology applies when a hand or hand with glove touches copper pad at Finger Touch B (Figure 2), which unlocks the car door.
