AI Technical Summary
Technical Problem
Existing servo drives for vehicle locks struggle to achieve precise and low-noise adjustments in dual-purpose applications, especially during the transition between the starting and ending positions of the adjustment element.
Method used
By introducing a stop element into the vehicle lock, the control unit adjusts the starting position of the element as needed to change the drive power of the servo driver. Combined with pulse width modulation (PWM) technology, this ensures precise and smooth movement of the adjustment element between different positions.
Benefits of technology
It achieves precise, low-noise switching of the adjustment element between the starting and ending positions, reduces the adjustment stroke, and lowers the overall noise level.
