Abstract:
A method for preventing a rollover of a vehicle or a tractor-trailer combination in curves, by counteracting a rollover risk of the vehicle by independent regulating interventions, performed without action by a vehicle driver, in a regulation system that actuates the drive and/or the brakes of the vehicle, the method including: capturing the current driving situation and the current load of the vehicle or the tractor-trailer combination as to the current driving position of the vehicle or the tractor-trailer combination, ascertaining a maximum admissible transverse acceleration at the current driving position, at which maximum admissible transverse acceleration the vehicle or the tractor-trailer combination just does not roll over, as to the current driving situation and the current load of the vehicle or the tractor-trailer combination. Also described is a related apparatus for preventing a rollover of a vehicle or a tractor-trailer combination in curves.

Claim (Index 28):
A vehicle, comprising:\n an apparatus for preventing a rollover of a vehicle or a tractor-trailer combination in curves, including at least one regulation system to actuate the drive and/or the brakes of the vehicle, wherein the regulation system counteracts a rollover risk of the vehicle by independent regulating interventions, carried out without action by a vehicle driver; wherein the at least one regulation system is configured to perform the following:\n a) capturing the current driving situation and the current load of the vehicle or the tractor-trailer combination in relation to the current driving position of the vehicle or the tractor-trailer combination; \n b) ascertaining a maximum admissible transverse acceleration at the current driving position, at which maximum admissible transverse acceleration the vehicle or the tractor-trailer combination just does not roll over, in relation to the current driving situation and the current load of the vehicle or the tractor-trailer combination; \n c) obtaining information items about the course of a route, proceeding from the current driving position of the vehicle or the tractor-trailer combination, comprising information items about the curvature profile of the route ahead; \n d) calculating maximum limit speeds that ensure a rollover-safe passage along the route ahead, in relation to the respective driving position along the route ahead, based on the curvature profile of the route ahead and based on the maximum admissible transverse acceleration according to the following calculation rule: \n v max \ue8a0 ( x ) = a y \ue89e \ue89e maxROP \u03ba \ue8a0 ( x ) ; e) calculating longitudinal decelerations that are required to prevent rollover, in relation to the respective driving position along the route ahead, based on the maximum limit speeds and based on the vehicle speed present at the current driving position of the vehicle or the tractor-trailer combination according to the following calculation rule: a xneed \ue8a0 ( x ) = v \ue8a0 ( x ) max 2 - v act 2 2 \u00b7 x ; f) determining a maximum required deceleration from the longitudinal decelerations that are required to prevent rollover, which are related to the respective driving position along the route ahead:\n a x max need =max( a x need ( x )); and \n g) regulating, based on the maximum required deceleration, the actual speed of the vehicle or the tractor-trailer combination, depending on the driving position along the route, to the maximum limit speed that was calculated for the relevant driving position so that there only is a regulation of the actual speed for the driving positions along the route at which there is a need for a longitudinal deceleration but no longitudinal acceleration.
