Detecting vehicle lane change involves detecting lane change if time derivative of vehicle's transverse acceleration parameter and/or yaw rate parameter exceeds predefined threshold

摘要

The method involves determining a vehicle's transverse acceleration parameter and/or yaw rate parameter, deriving its (their) time derivative(s) and detecting a lane change if the time derivative(s) exceeds a predefined threshold. A bend or lane change can be detected when a certain difference between the revolution rate of the fastest rear wheel and the vehicle speed exists for a defined period. Independent claims are also included for the following: a method of detecting a bend and/or lane change and an arrangement for detecting a bend and/or a lane change by a vehicle.
