Abstract (en)
[origin: WO03098098A1] The invention relates to a method and device for determining the curvature of a vehicle lane. The inventive method involves the determination of the vehicle speed, the yaw rate and the steering angle. The method is characterized in that, according to the measured vehicle speed and the measured yaw rate, the curvature of the lane is calculated by using a single-lane model based on the vehicle speed and the measured steering-wheel angle or by using a yaw rate model based on the measured yaw rate and the vehicle speed. The inventive device comprises a vehicle speed sensor (2), a yaw rate sensor (1) and a steering angle sensor (14). Said device is characterized by having a decision unit (7), which is coupled to both the vehicle speed sensor (2) and the yaw rate sensor (1) and which receives, as input signals, the vehicle speed (vSP) and measured yaw rate (dpsi/dt), and these input signals enable a single-lane model or a yaw rate model to be selected as a calculation model on the basis of the speed (vSP) and the measured yaw rate (dpsi/dt). The inventive device is also characterized by having a calculating device (8, 9, 11) with which the curvature of the lane can be calculated by using the selected model. When using the single-lane model, the curvature is determined based on the vehicle speed and the measured steering angle. When using the yaw rate model, the curvature is calculated based on the measured yaw rate and the vehicle speed.
