Abstract

The invention concerns a motor vehicle (10) comprising a system (52) for controlling the handling thereof and a system (50) for diagnosing the condition of its tyres. Said control system (52) is adapted to control the vehicle handling based on the diagnosed state of the tyres.

Claims

1. Vehicle equipped with a system for controlling its handling and a system for diagnosing the state of its tires, wherein said control system is adapted to control the handling of the vehicle as a function of the diagnosed state of the tires.

2. Vehicle according to claim 1, wherein the diagnostic system is adapted to diagnose the inflated state of the tires, and the control system is adapted to control the handling of the vehicle in a predetermined security mode when the diagnosed inflated state is not satisfactory.

3. Vehicle according to claim 2, wherein the control system is adapted to limit the speed of the vehicle when the diagnosed inflated state is not satisfactory.

4. Vehicle according to claim 2, wherein the control system is adapted to reduce the braking power applied to a wheel when the tire of this wheel is diagnosed as being under-inflated.

5. Vehicle according to claim 4, wherein the control system is adapted to increase the braking power applied to the wheels of the vehicle whose tires are diagnosed as having satisfactory inflated states to compensate the reduction of the braking power applied to the wheel equipped with a tire diagnosed as being under-inflated.

6. Vehicle according to claim 3, wherein the control system is adapted to reduce the braking power applied to a wheel when the tire of this wheel is diagnosed as being under-inflated.

7. Vehicle according to claim 6, wherein the control system is adapted to increase the braking power applied to the wheels of the vehicle whose tires are diagnosed as having satisfactory inflated states to compensate the reduction of the braking power applied to the wheel equipped with a tire diagnosed as being under-inflated.
