Abstract
A clamping mechanism for an adjustable steering column for a vehicle has an actuator coupled to a clamp for clamping the steering column in a desired position. The actuator is controlled to adjust clamping force of the clamp in the event of vehicle crash to thereby control energy absorption, and the actuator can be electrically controlled. Sensors are used to calculate weight, posture, position, etc. of the driver and thereby predetermine the settings required for energy absorption to protect the driver. The actuator depends on the sensed settings to control the clamping absorption energy.
