Abstract
A variable force limiter control system for a vehicle includes a variable force limiter mechanism, a relative speed sensor, an acceleration sensor and an electronic control unit. The variable force limiter mechanism is configured to change a force limiter load. The relative speed sensor is configured to detect a relative speed of the vehicle with respect to a collision object before a collision. The acceleration sensor is configured to detect an acceleration of the vehicle. The electronic control unit is configured to predict a severity of a collision on the basis of at least the relative speed. The electronic control unit is configured to control the force limiter load on the basis of both the predicted severity and the acceleration in an initial stage of the collision of the vehicle.
