Abstract
In a method for controlling an occupant protection device in a vehicle and a control device therefor, a crash sensor supplies a crash signal. A crash variable derived from the crash signal is compared with a threshold, the occupant protection device is controlled as a function of the overshooting of the threshold by the crash variable. The threshold includes at least one term which, depending on the configuration of the crash signal, supplies a contribution which raises the threshold or a contribution which lowers the threshold.
Claims9
A method for controlling an occupant protection device in a vehicle, which comprises the steps of:
- using a crash sensor for supplying a crash signal;
- deriving a crash variable from the crash signal;
- comparing the crash variable with a threshold, the threshold includes at least one term determined by one of the crash signal and a derived signal derived from the crash signal, the term is configured such that, depending on a configuration of the crash signal, it supplies one of a first contribution which raises the threshold and a second contribution which lowers the threshold, and the term is determined by positive and negative components summed separately from one another of one of the crash signal and the derived signal;
- and
- controlling the occupant protection device in dependence on an overshooting of the threshold by the crash variable.
A control device for an occupant protection device, comprising:
- a microprocessor programmed to:
- receive a crash signal from a crash sensor;
- derive a crash variable from the crash signal;
- compare the crash variable with a threshold, the threshold includes at least one term determined by one of the crash signal and a derived signal derived from the crash signal, the term is configured such that, depending on a configuration of the crash signal, it supplies one of a first contribution which raises the threshold and a second contribution which lowers the threshold, and the term is determined by positive and negative components summed separately from one another of one of the crash signal and the derived signal;
- and
- control the occupant protection device in dependence on an overshooting of the threshold by the crash variable.
