Problems solved by technology

Since a 100% correct mounting position of the inertial sensor can hardly be guaranteed, this calibration of the inertial sensor is necessary, but also entails corresponding costs, since generally a long period of time is required for monitoring the measurement data, and Effective measurement only in certain circumstances

Embodiment Construction

[0016] figure 1 A simplified schematic diagram shows a motor vehicle 1 with a reference coordinate system (COG), which detects accelerations in three spatial directions x, y, z, and an inertial sensor coordinate system for this purpose, as well as an inertial sensor 2 L, the inertial sensor coordinate system deviates, depending on the mounting position of the inertial sensor 2 , from a reference coordinate system R oriented parallel to the vehicle coordinate system COG. Furthermore, at least one rotational speed sensor is associated with at least one of the wheels of motor vehicle 1 , which forms reference sensor 3 . Preferably, a total of two rotational speed sensors are provided. The inertial sensor 2 is connected, for example directly or via a controller, to a safety device 4 , for example an airbag arrangement, in order to trigger the safety device 4 as required based on the measurement data detected by the inertial sensor.

Abstract

The invention discloses a method for operating an inertial sensor and for operating a vehicle having such an inertial sensor, and such a vehicle. The invention relates to a method for operating an inertial sensor (2) of a vehicle, in particular a motor vehicle, wherein measurement data of at least one measurement variable of the inertial sensor are captured during operation of the vehicle and arechecked for error values in order to calibrate the inertial sensor. According to the invention, during operation of the vehicle, measurement data of a different measurement variable, which, however, correlates with the measurement variable of the inertial sensor, are captured by means of a reference sensor and are compared with the measurement data of the inertial sensor in order to record the error values in accordance with a deviation of the measurement data of the inertial sensor from the measurement data of the reference sensor.

Description

technical field [0001] The invention relates to a method for operating an inertial sensor of a vehicle, in particular a motor vehicle, wherein measured data of measured variables of the inertial sensor are recorded during operation of the vehicle and checked for error values ​​for calibration. [0002] The invention also relates to a method for operating a vehicle, in particular a motor vehicle, which has at least one inertial sensor, wherein a function of the vehicle, in particular a safety function / safety Devices such as air bags or braking systems. [0003] The invention also relates to a vehicle, in particular a motor vehicle, having at least one inertial sensor and a device, in particular a safety device, such as an airbag or a brake, which can be triggered in particular on the basis of measured data of at least one measured variable of the inertial sensor system, braking system especially ESP. Background technique [0004] It is already known from laid-open document ...
