Abstract
Method for controlling tire pressure in a motor vehicle having a wheel including a gas-filled tire, and a tire-pressure-controlling device for controlling a filling pressure in the gas-filled tire. The filling pressure within the setpoint pressure value range which is characterized by a driving setpoint pressure value is set by means of the tire-pressure-controlling device. When a motor vehicle is parked the tire-pressure-controlling device predefines a parked setpoint pressure value which deviates from the driving setpoint pressure value which is provided for the driving mode, in order to prevent a flat tire while the vehicle is parked.
Claims20
A method for controlling tire pressure in a motor vehicle having a wheel including a gas-filled tire, and a tire-pressure controller device for controlling a filling pressure in the gas-filled tire, said method comprising the steps:
- determining a driving setpoint pressure value;
- setting the filling pressure within a setpoint pressure value range of said determined driving setpoint pressure value;
- predefining by means of said tire pressure controller device a parked setpoint pressure value when the motor vehicle is parked which deviates from the driving setpoint pressure value provided for the driving mode, whereby a flat tire is prevented while the vehicle is parked when conditions indicative of a risk of tire deflation are determined.
