Abstract

A method of stabilizing a vehicle in the event of a loss of tire pressure is provided. A driving-stability-related system, which can be manually activated and/or deactivated, is automatically activated when a loss of tire pressure is determined or when the tire pressure is below a defined threshold. The driving-stability-related system preferably remains deactivated when it was manually deactivated again after an automatic activation, at least for a given ignition-cycle.

Claims

1. A method of stabilizing a vehicle in an event of a loss of tire pressure, the method comprising the acts of:

determining an activation state of a driving-stability-related system, which system is manually deactivatable; and

automatically activating the driving-stability-related system that is in a manually deactivated state upon determining a loss of tire pressure or a tire pressure below a defined threshold.

2. The method according to claim 1, wherein the driving-stability-related system remains deactivated following a manual deactivation again after the automatically activating act.

3. A system for stabilizing a vehicle in an event of a loss of tire pressure, the system comprising:

a driving-stability-related system;

a tire pressure sensing system; and

a control system receiving inputs from the tire pressure sensing system and the driving-stability-related system, wherein the control system operates to automatically activate the driving-stability-related system upon sensing a loss of tire pressure or a tire pressure below a defined threshold when the driving-stability-related system is in a manually deactivated state.
