A sensor arrangement and engine management device for a combustion engine, the engine management device including the sensor arrangement for detecting variables indicative of engine load, a mechanism for determining engine load on the basis of measured values supplied by the sensor, as well as a throttle-valve position control loop. At least two of the sensors of the sensor arrangement, which may include a mass air-flow sensor, an intake-air temperature sensor, an induction-pipe pressure sensor, and a throttle-valve position sensor, are microintegrated in a modular unit. The engine management device is made such that a sensor device with the at least two sensors, the mechanism for determining, engine load and/or the throttle-valve position controller used in the throttle-valve position control loop are microintegrated in a modular unit. The engine management device can be used, for example, for controlling a spark ignition engine in a motor vehicle.

A system for monitoring the vehicle tire inflation pressure has a device for detecting the vertical acceleration of the tire or of a vehicle component connected therewith and the longitudinal speed of the vehicle, as well as having an analyzing unit which determines the tire inflation pressure from the measured vertical acceleration data and the measured vehicle longitudinal speed data. The analyzing unit contains a trainable estimating unit, particularly a neuronal network, which is trained by predeterminable training example data with different tire inflation pressure values and vehicle longitudinal speed values. In the trained condition, the estimating unit determines the tire inflation pressure at least as a function of the measured vertical acceleration and vehicle longitudinal speed data fed directly or preprocessed on an input side thereof. The system provides continuous tire inflation pressure monitoring in the case of road vehicles.

The invention provides a process and apparatus for controlling combustion in an Otto combustion engine in which the control variables that control combustion are determined for a particular power cycle as a function of the detected combustion course of a preceding power cycle. According to the invention, a desired burn-through function value for a particular power cycle is precalculated based on values of pertaining influence factors detected in a preceding power cycle, to determine an actual burn-through function value of the particular power cycle in real time. The desired burn-through function is compared with the actual burn-through function and actualized values for the burn-through function influence factors are determined. These factors are used to determine the control variable values for a subsequent power cycle.
