A device and a method for activating a personal protection device are provided, in which a feature vector with at least two features is formed by an evaluation circuit from at least one signal of an accident sensor system. The evaluation circuit classifies the feature vector in the corresponding dimension using at least one class boundary. The activation circuit generates an activation signal which activates the personal protection device.

A method for crash type identification for a vehicle in which sensor data from the left vehicle side and from the right vehicle side are recorded and analyzed via at least two sensor units, as well as an associated device for crash type identification for a vehicle. The sensor data, recorded after an impact, are gated, at least one first gating of the recorded sensor data being checked for fulfillment of a stability criterion and, after meeting the stability criterion, at least one second gating of the recorded sensor data is compared with a predefined threshold value, a first criterion for an asymmetrical impact flag signal being recognized when the second gating of the recorded sensor data exceeds the predefined threshold value and/or falls short of the predefined threshold value.

A method for determining cylinder-specific combustion features of an internal combustion engine, the cylinder-specific combustion features being ascertained from a variable which represents the crankshaft speed, especially being ascertained from a signal of a crankshaft sensor or camshaft sensor. The cylinder-specific combustion features include a combustion position of at least one cylinder and/or a torque of the crankshaft.

The present invention relates to a method for detecting an angular position signal representing the rotary motion of a rotating part of an internal-combustion engine. The internal-combustion engine includes at least one combustion chamber. In addition, a speed sensor of the type mentioned initially is provided, the speed sensor outputting a rotation-measurement signal representing the rotary motion of a sensing wheel connected with the rotating part. At least one pressure sensor is also provided that outputs a pressure signal representing the pressure in a combustion chamber. The method according to the present invention has the following steps: Detect the pressure signal, detect the rotation-measurement signal, calculate a correction quantity that is a function, at the least, of the detected pressure signal and rotation-measurement signal, and determine the angular position signal by linking the detected rotation-measurement signal with the correction quantity. The core of the present invention is the identification and very good compensation of the sensing wheel error by performing a joint evaluation of the rotational-speed signal and the compression chamber pressure of one or more indicated cylinders.
