Abstract

A dynamic vehicular system for controlling pressure in tires of a vehicle. The system has sensors for detecting dynamic conditions of the vehicle and for detecting stutter. An air-supply includes a compressor and at least one storage tank for supplying pressurized air to the tires of the vehicle. An electronic controller processes outputs of the sensor and is connected to valves between the air supply and at least one of the tires for varying pressure in the one tire on detection of stutter.

Claims

1. A dynamic vehicular system for controlling pressure in tires of a vehicle, the system comprising:

sensors for detecting dynamic conditions of the vehicle and for detecting stutter;

air-supply means including a compressor and at least one storage tank for supplying pressurized air to the tires of the vehicle; and

electronic control means for processing outputs of the sensor and for varying pressure in at least one of the tires on detection of stutter.

2. The tire-pressure control system defined in claim 1 further comprising:

a pneumatic suspension system including a respective pneumatic spring associated with each of the tires;

pneumatic lines connected between the suspension system and the air-supply means; and

valve means in the pneumatic line between the suspension system and at least one of the pneumatic springs and connected to the electronic control means for varying the pressure in at least one of the pneumatic springs on detection of stutter.

3. The tire-pressure control system defined in claim 2 wherein the control means varies the pressures in the one tire and the one spring differently.

4. The tire-pressure control system defined in claim 1, further comprising

a pneumatic engine mount;

a pneumatic line connected between the engine mount and the air-supply means; and

valve means in the pneumatic line between the engine mount and the air-supply means anc connected to the electronic control means for varying the pressure in the engine mount on detection of stutter.

5. The tire-pressure control system defined in claim 1 wherein, a predetermined time after stutter is detected, the electronic control means reestablishes an original pressure condition in the one tire.

6. The tire-pressure control system defined in claim 1 further comprising:

a pneumatic suspension system including a respective pneumatic spring associated with each of the tires;

pneumatic lines connected between the suspension system and the air-supply means;

valve means in the pneumatic line between the suspension system and at least one of the pneumatic springs and connected to the electronic control means for varying the pressure in at least one of the pneumatic springs on detection of stutter;

a pneumatic engine mount;

a pneumatic line connected between the engine mount and the air-supply means; and

valve means in the pneumatic line between the engine mount and the air-supply means anc connected to the electronic control means for varying the pressure in the engine mount on detection of stutter, the electronic control means reestablishing an original pressure in the one tire, engine mount, and pneumatic spring in a predetermined priority order.
