Abstract
A process to prevent a vehicle, such as a tractor-trailer, from overturning while negotiating a curve recognizes the potential for overturning, and automatically activates a preventive braking process. In addition, the automatic braking process is terminated in a timely fashion to avoid overbraking the vehicle. This is accomplished by subjecting at least one wheel on the inside of the curve to a relatively weak braking force during the automatic braking process, and by adjusting the braking parameters in accordance with the vehicle's response characteristics.
Claims9
A process to prevent overturning of a vehicle around a longitudinal axis of said vehicle when rounding a curve, in which danger of overturning is evaluated, and braking is automatically applied as required, comprising the following steps:
- a) applying a first braking force to at least one first wheel of said vehicle, wherein said at least one first wheel is on the inside of said curve,
- b) wherein an indication of a potential overturning of said vehicle requires a characteristic reduction of a rotational speed of said at least one first wheel on the inside of said curve,
- c) applying a second braking force to at least one second wheel of said vehicle, wherein said at least one second wheel is on the outside of said curve, to prevent said vehicle from overturning,
- d) wherein said first braking force is weaker than said second braking force,
- e) terminating said first and second braking forces when a rotational speed of said at least one first wheel on the inside of said curve accelerates in a predetermined characteristic manner.
