Abstract

A system for and a method of controlling the stability of a vehicle includes an electronic control system controlling a vehicle stability control subsystem based at least in part on static tire data received by the electronic control unit.

Claims

1. A system for controlling the stability of a vehicle comprising:

a vehicle stability control subsystem including components of the vehicle that affect stability of the vehicle during operation;

a tire having an ID tag containing cornering stiffness data of said tire; and

an electronic control unit coupled in communication with said ID tag to receive the data contained in said ID tag, said electronic control unit being programmed to calculate at least one of a wheel speed, a vehicle speed, a yaw rate and a sideslip based at least in part as a function of said cornering stiffness data from said ID tag, said electronic control unit being programmed to control said vehicle stability control subsystem based at least in part upon the calculation(s) made by said electronic control unit based upon the data received by said electronic control unit from said ID tag, said vehicle stability control subsystem selected from the group consisting of the torque of a powertrain of the vehicle, the apply force of a braking component of the vehicle, a steering angle controlled by steering actuators, and a condition of a component of the vehicle suspension system.

2. The system of claim 1 wherein the electronic control unit is programmed to utilize at least one of the equations:

WS=rev/th×

th/lp×

lp/ms=rev/ms;

WS₁=rev/ms×

1000 ms/s×

2π

R=m/s;

3. The system of claim 1 further comprising at least one sensor configured to detect at least one vehicle condition, wherein said electronic control unit is coupled in communication with said sensor to receive data representative of the vehicle condition detected by said sensor, said electronic control unit being programmed to control said vehicle stability control subsystem based at least in part upon the data received by said electronic control unit from said sensor.

4. The system of claim 3 wherein the vehicle condition is one of a steering wheel angle, a vehicle yaw rate, a longitudinal vehicle acceleration, a lateral vehicle acceleration, a wheel speed, and a vehicle speed.

5. The system of claim 1 further comprising a mechanism to transmit the sensor data to said electronic control unit controller.

6. The system of claim 1 wherein said electronic control unit controls said vehicle stability control subsystem by generating an output signal, said vehicle stability control subsystem responsive to the output signal.

7. The system of claim 1 wherein said ID tag is an RFID tag.

8. The system of claim 7 wherein said RFID tag is a passive RFID tag.

9. A system for controlling the stability of a vehicle comprising:

a vehicle stability control subsystem including components of the vehicle that affect stability of the vehicle during operation;

a tire having an ID tag containing static rolling radius and cornering stiffness data of said tire; and

an electronic control unit coupled in communication with said ID tag to receive the data contained in said ID tag, said electronic control unit being programmed to calculate at least one of a wheel speed, a vehicle speed, a yaw rate and a sideslip based at least in part as a function of said static rolling radius and said cornering stiffness data from said ID tag, said electronic control unit being programmed to control said vehicle stability control subsystem based at least in part upon the calculation(s) made by said electronic control unit based upon the data received by said electronic control unit from said ID tag, said vehicle stability control subsystem selected from the group consisting of the torque of a powertrain of the vehicle, the apply force of a braking component of the vehicle, a steering angle controlled by steering actuators, and a condition of a component of the vehicle suspension system.
