Embodiment Construction

[0050] exist figure 1 In is shown a vehicle 10 comprising a schematically represented device according to an embodiment of the invention, wherein the device implements figure 2 in the method according to the invention. The device is implemented as a controller 12 and includes an assay device 14 , not shown in greater detail, which is implemented as a software component of the controller. In addition, a lateral acceleration sensor 16 and a yaw rate sensor 18 are shown. These sensor types are commercially available and are installed, for example, in commonly used ESP and ASR systems. Steering angle sensor 20 is likewise shown. This can be a sensor in the steering gear which, for example, detects the current deflection of the gear rack of the steering gear. All of the mentioned sensors 16 , 18 , 20 provide their measurement results via a communication bus not shown in particular (for example a CAN bus) to the controller 12 and / or correspondingly determined signals can be pas...

Abstract

The invention relates to a determination of the steering direction of a vehicle (10). The method used to determine the steering direction of the vehicle includes: determining a lateral acceleration value (Q) of the vehicle (10); determining at least one of a yaw rate value (G) of the vehicle (10) and the steering angle value (L) of the vehicle (10); determining a friction value (R); determining the steering direction based on the measured value. Furthermore, the present invention relates to a device, in particular a controller (12) for a vehicle (10), with a measuring device (14) for performing the aforementioned steps. The invention further discloses a method in which not all measured values (L, G, R, Q) contribute to the measured steering direction, provided that they are in a predetermined range.

Description

technical field [0001] The invention relates to a method and a device for determining the direction of a turn for a vehicle. The vehicle can be a motor vehicle and in particular a passenger car or a truck. Background technique [0002] Knowledge about the direction of the curve the vehicle is currently driving is important for a wide variety of driver assistance systems and especially driving dynamics control systems such as electronic stability programs (ESP). More precisely, it is important whether a right-hand or a left-hand curve is currently being driven, for example in order to stabilize the driver autonomously braking the wheels on the inside of the curve. Driver-initiated steering interventions can also be carried out depending on the direction of the turn. [0003] The direction of turning is currently determined from the steering angle, which can be obtained, for example, from the steering gear with a steering wheel angle sensor or generally from a steering servo...
