Method for controlling speed of motor vehicle prior to vehicle traveling around bend involves controlling speed in dependence of target speed determined by iterative process

摘要

The method involves determining a target speed (Vsoll) before the vehicle reaches the curve by an iterative process in dependence on the vehicle actual speed (VFZ), the maximum transverse acceleration (aymax) and curve radius (R) of the bend determined using a navigation system and GPS receiver. The target speed approaches a limit speed at which the curve can be travelled through safely. The speed of the vehicle is controlled in dependence on the target speed and the actual speed, with the speed being reduced by a reduction in drive torque or an increase in braking torque.
