FAQs Flashcards
What happens when the battery goes flat – a cable can be installed within the vehicle but what about externally?
Internal release is achieved with a mechanical cable concealed if it is not used as part of the handle feature.
External would be linked to a key barrel
What is the approx. drain on the battery, assume system is always live?
The quiescent current is about 0.1 milli-amps in sleep mode and 22 mA in idle mode
What happens in the event of a crash – i.e., getting people out of the vehicle?
Pull the mechanical release if no power is available. We have other strategies available but are not yet implemented mainly to the low interest from customers who believe that the internal mechanical release is sufficient.
Ignition – can you also supply a keyless system?
We have our own system but not in production yet. I can recommend you to try Trimark corporation
PCL / TGL latch – please can we have approx. weight of these two latches?
640 grams PCL with Clinch, 480 without. TGL about 410 grams
Key Fob – assume you can supply?
Trimark Corporation
“Also am I correct in assuming that the powered claw will jack the door slightly open when unlatching? Enough to fit fingers behind the door edge.
When unlatching the gap is determined by the back force provided by the seal and struts that may be bias in that direction and not latch dependent. Once engaged in the Open state the claw will remain in the open state until fully pass the secondary state and will not re-engage the cinching automatically until the claw has reached the fully open state and is re position to secondary.
We are looking for access to the trailing edge of door to lift slightly before the gas strut takes over and fully opens the door.”
We can add an linear actuator to force the opening door further if the force of the seal is not sufficient to provide the adequate gap.
Regular operation and power loss operation of the side door latch
The interior handle can be coupled to both the electrical and mechanical release with each being operated at different handle angles.
E-release would occur when stroking the handle and if the handle is fully pulled then the mechanical release would occur.
For the rear doors, the interior handle can be solely e-release so as to provide child lock functionality.
Anti trap
Intended to prevent objects trapped between the door and its frame from sustaining serious damage - the clinch operation will stop and return to neutral.
Anti pinch
- same as anti trap but no neutral return
Emergency Manual release
Pulling door handle during clinch will auto relase and stop actuation
Pulling the handle during the power clinch operation will release the door and interrupt the clinch operation. This arrangement has a dual action:
Due to the fact that the Control Electronics Module is integrated in the latch, the hall sensors de-tect the movement of the handle and instantly stops the electrical operation
Independently from the electrical interruption, the manual release proceeds to release the door in the conventional manner, thus, providing a safety redundancy, which is available at all times and condition.
Manual Release
The mechanism is adapted with two release levers to enable door release from the inside or the outside of the vehicle. It can also to couple to the Key barrel lock.
Integrated Release Switches
Intended to replace the switches normally fitted to the door handle
It also enables the implementation in the shortest time possible of a number of other im-portant functions
The latch is integrated with sensors that are responsive to the movement of the release lev-ers (interior or exterior)
By operating either of the release levers within the free travel segment “5mm of Pre-travel”, the door handle effectively acts as a button or a switch, which is located inside the latch.
With a “PKE” system, this arrangement is intended to enable simultaneous unlock and re-lease of the door in the shortest time possible.
This arrangement is also used to trigger the alarm when the car is locked
It enables the fasted possible drop glass in convertible cars.
More importantly, it is used to enable instantaneous interruption of the clinch operation
It makes redundant the need to use an external, standalone switch to enable electrical re-lease.
Door Status Sensing
The mechanism is adapted with position sensors to report to the driver the state of the mechanism at all times. It reports if the door is latched, open or in secondary ( i.e. Ajar). It reports if the latch is functioning as intended at all time
One pulse release
The mechanism is adapted to ensure release is completed after initiating just one release request. It is particularly intended to ensure if the door is iced up, so that the focus is shifted on efforts to push or pull the door open.
More importantly, it is necessary to ensure the door open assist mechanism (with optional Ice Breaker) does not operate against a latched door should one be used in conjunction with the latch.
It also enables timely coordination between the release request, drop glass and the door open as-sist mechanism such that the door open mechanism operation is perceived as a smooth continua-tion of the release actuation
