Abstract
A control device in a motor vehicle for detecting an impact and for detecting a rotational movement includes a transversal acceleration pick-up in each half of the vehicle, as defined by the longitudinal axis of the vehicle, and a longitudinal acceleration pick-up. An evaluation device evaluates longitudinal acceleration and transversal acceleration variables and derives a rotational movement variable from the transversal acceleration variables.
Claims8
In combination with a vehicle having a longitudinal axis defining halves of the vehicle, a protection device for head-on impact protection, protection devices for side impact protection each disposed in a respective half of the vehicle, and a protection device for roll-over protection, a control device for controlling various protection devices, comprising:
- one longitudinal acceleration pick-up;
- two transversal acceleration pick-ups each disposed in one respective half of a vehicle, and
- an evaluation device for evaluating longitudinal acceleration and transversal acceleration variables and for deriving a rotational movement variable from the transversal acceleration variables;
- said evaluation device outputting a first control signal dependent at least on the longitudinal acceleration, to said protection device for head-on impact protection;
- said evaluation device outputting a second control signal dependent at least on the transversal acceleration, to said protection devices for side impact protection, with the transversal acceleration received by said protection devices for side impact protection in the halves of the vehicle being determinative;
- and
- said evaluation device outputting a third control signal dependent on the rotational movement variable, to said protection device for roll-over protection.
