Problems solved by technology

This procedure is firstly complex, since there must be a corresponding test section with sufficient curves
Furthermore, there is the inherent risk that, in the event of an accident, an ESP intervention may be required during the first bend, although this ESP has not yet been checked
Finally, the driver is distracted from the driving task by possibly necessary false warnings during or after the first bend due to a possibly incorrect mounting position

Embodiment Construction

[0043] Figure 1A , B shows a flow chart of a method for determining the orientation of a sensor unit according to an embodiment of the present invention.

[0044] Figure 1A A first method for determining the orientation of a sensor unit is shown. The sensor unit has at least one acceleration sensor and is installed in the vehicle. The method comprises the steps of: detecting S110 a first sensor signal of the acceleration sensor in a state of no acceleration of the vehicle; detecting S120 a second sensor signal of the acceleration sensor in response to a linear acceleration of the vehicle; and based on the first sensor signal and the second sensor signal Ascertain S130 the orientation of the sensor unit relative to the vehicle.

[0045] Figure 1B A second method for determining the orientation of a sensor unit of a vehicle is shown, wherein the vehicle defines a longitudinal axis, a transverse axis and a vertical axis. The vertical axis is parallel to the gravitational ac...

Abstract

The invention relates to a method (100) for ascertaining an orientation of a sensor unit (50), which has at least one acceleration sensor and is assembled into a vehicle (70). The method has the following steps: detecting (S110) a first sensor signal from the acceleration sensor in an acceleration-free state of the vehicle (70); detecting (S120) a second sensor signal from the acceleration sensorin response to a linear acceleration of the vehicle (70); and ascertaining (S130) the orientation of the sensor unit relative to the vehicle (70) on the basis of the first sensor signal and the secondsensor signal.

Description

technical field [0001] The invention relates to a method and a device for determining the orientation of a sensor unit and in particular to a method and a device for quickly identifying the installation orientation of an ESP unit. Background technique [0002] The Electronic Stability Program (ESP) unit is a driver assistance system that detects unusual vehicle positions and triggers corresponding countermeasures accordingly. To fulfill its function, an ESP unit typically has at least one yaw rate sensor and a lateral acceleration sensor. These sensors constitute a sensor unit. In ESP units commonly used today, the sensor unit has to be installed in a defined orientation in the vehicle. Only in this way can the sensor unit function properly and clearly distinguish possible abnormal lateral accelerations from normal vehicle longitudinal accelerations or braking processes. [0003] Due to the importance of the ESP, its installation needs to be checked in order to ensure rel...
