First Claim
Patent Images
1. A method for ensuring safe tire emergency running operation in a motor vehicle that is equipped with tires having emergency running properties when the tire pressure is greatly reduced or absent altogether, and a device which detects that the motor vehicle is in a tire emergency running mode, wherein:
- upon detection of tire emergency running operation, a speed limiting device limits driving speed of the motor vehicle such that it cannot exceed a limit value;
at least one further predeterminable condition must be satisfied in order for the driving speed of the motor vehicle to be limited when tire emergency running operation is detected;
an accelerator pedal displacement threshold value is predetermined; and
limitation of driving speed is interrupted for a predeterminable period of time if the accelerator pedal is depressed beyond the pedal displacement threshold value.
