The invention relates to an inertial sensor arrangement (), in particular for installation in a motor vehicle, having a sensor module () which is fitted to a carrier () and comprises a micromechanically produced inertial sensor and an evaluation circuit. The invention provides for the sensor module () to be connected to the carrier () by means of an elastic coupling element ().

Inertial sensor arrangement

Disclosed is a gas measuring device which comprises compensation of disturbances and offers high accuracy of measurement immediately after being activated. Said gas measuring device is provided with a gas sensor () for generating a measuring signal (S) that depends on the gas concentration and can have a spurious component while a high-pass filter () having an adjustable limiting frequency is mounted downstream of said gas sensor (). The limiting frequency can be predefined according to the spurious component by means of a selection unit.

Gas measuring device and method with compensation of disturbances

A method of operating a resistance heating element and a device for carrying out the method are described. During a first step, the resistance of a resistor of the resistance heating element is determined at a known base temperature. In a second step, the resistance setpoint value is determined as a function of resistance of the resistor at the known base temperature and known temperature coefficients. The resistance heating element is activated by approximately setting the resistance setpoint value in order to heat the resistance heating element to the given setpoint temperature.

In order to determine the fuel quantity to be fed into an internal combustion engine during each stroke of the engine, the air mass sucked into each cylinder for combustion during each intake stroke is determined based on an intake-pipe pressure. A current air mass is determined using a measured value for the intake-pipe pressure. Subsequently, during a period in which there is no change in an air intake cross-section for each cylinder, the air mass is determined using a projected intake-pipe pressure, and the fuel quantity to be fed to each cylinder during the current and subsequent intake strokes is determined based on the air mass determinations and a wall film model.
