Abstract
A method and apparatus is provided for controlling the handling dynamics of a vehicle, in particular a commercial vehicle, fitted with an ABS system. The method requires varying the brake pressure of the vehicle in the event of an impending wheel lock up to prevent excessive wheel slippage. The method and apparatus are configured such that any decrease in the roll-over stability of the vehicle while negotiating a curve is detected with an ABS system.
Claims12
A method for controlling handling dynamics of a motor vehicle equipped with an ABS system which varies a braking pressure when a wheel shows a tendency to lock up, in order to prevent excessive wheel slip, the method comprising the acts of:
- determining a potential situation for a roll over stability problem of the vehicle;
- detecting a decrease in roll over stability of the vehicle when negotiating a curve using ABS control intervention;
- wherein the detecting act comprises:
- (a) triggering a braking intervention that is small relative to a maximum possible braking force if there is a potential situation for the roll over stability problem;
- (b) monitoring the ABS system;
- and
- (c) triggering one of an alarm signal or a control intervention if the ABS system responds when the braking intervention is triggered.
An apparatus for controlling the handling dynamics of a motor vehicle equipped with an ABS system, in which the braking pressure can be varied when the wheels exhibit a tendency to lock up, in order to prevent excessive wheel slip, comprising:
- means for determining a potential situation for a roll-over stability problem of the vehicle;
- and
- means for detecting a decrease in the roll over stability of the vehicle as it negotiates a curve by monitoring an ABS system in the potential situation while triggering a braking intervention that is small relative to the maximum possible braking force.
