Method and Device for Determining the Installation Position of a Sensor Module in a Vehicle, and Vehicle Having Such a Device

摘要

A method and device are provided for determining the installation position of a sensor module in a vehicle—namely, for determining whether the sensor module has its longitudinal axis oriented longitudinally or transversely. The sensor module has a longitudinal acceleration sensor for measuring a longitudinal module acceleration in the direction of the longitudinal axis and/or a transverse acceleration sensor for measuring a transverse module acceleration transversely with respect to the longitudinal axis. To this end, while the vehicle is travelling, a measured longitudinal module acceleration and/or a measured transverse module acceleration is compared with a longitudinal vehicle acceleration and/or a transverse vehicle acceleration ascertained in another way. By the comparison, at least one degree of conformity is ascertained, which represents the conformity of a measured module acceleration with a calculated vehicle acceleration. The installation position of the sensor module is then determined by means of the degree of conformity.

1. A method for determining the installation position of a sensor module in a vehicle, the sensor module having at least one of a longitudinal acceleration sensor for measuring a module longitudinal acceleration in a direction of a longitudinal axis of the sensor module and a transverse acceleration sensor for measuring a module transverse acceleration transversely with respect to the longitudinal axis of the sensor module, the method comprising comparing at least one of a measured module longitudinal acceleration and a measured module transverse acceleration during vehicle travel against at least one of a calculated vehicle longitudinal acceleration and a calculated vehicle transverse acceleration; obtaining at least one degree of correspondence between (i) the at least one of the measured module longitudinal acceleration and the measured module transverse acceleration and (ii) the at least one of the calculated vehicle longitudinal acceleration and the calculated vehicle transverse acceleration based on comparing; and determining an installation position of the sensor module based on the at least one degree of correspondence.
