Abstract

A vehicle control system includes: a communication device provided in a vehicle to receive information relating to another vehicle from outside the vehicle; and a control device that performs travel control on the vehicle on the basis of information pertaining to a transfer function for a control target value used during travel control of the other vehicle and the control target value of the other vehicle, which is obtained via the communication device of the vehicle. Further, a vehicle control system includes: a communication device provided in a vehicle; and a control device that performs travel control using information relating to another vehicle, which is received from outside the vehicle via the communication device, wherein the communication device transmits information pertaining to a transfer function for a control target value used during the travel control.

Claims

1. A vehicle control system comprising:

a communication device provided in a vehicle to receive information relating to another vehicle from outside the vehicle; and

a control device that performs travel control of the vehicle on the basis of information pertaining to a transfer function for a control target value used during travel control of the other vehicle, wherein the information pertaining to the transfer function indicates a control response characteristic relative to the control target value of the other vehicle, and the control target value of the other vehicle, the control response characteristic is used during travel control of the other vehicle and the control target value of the other vehicle is obtained via the communication device of the vehicle.

2. The vehicle control system according to claim 1, wherein the control device performs the travel control on the vehicle on the basis of specification information relating to the other vehicle, which is obtained via the communication device.

3. The vehicle control system according to claim 1, wherein the information pertaining to the transfer function of the other vehicle is obtained via the communication device of the vehicle.

4. The vehicle control system according to claim 1, wherein the control device calculates the information pertaining to the transfer function of the other vehicle on the basis of the control target value of the other vehicle and a measured value of an actual output for the control target value.

5. The vehicle control system according to claim 4, wherein the measured value of the actual output of the other vehicle is measured by the other vehicle, and

the vehicle obtains the measured value of the actual output of the other vehicle via the communication device of the vehicle.

6. The vehicle control system according to claim 4, further comprising a measurement device that measures the actual output for the control target value of the other vehicle.

7. The vehicle control system according to claim 1, wherein the control device performs the travel control on the basis of information pertaining to the transfer function of the vehicle.

8. The vehicle control system according to claim 1, wherein the control device calculates an actual output value for the control target value of the other vehicle using the information pertaining to the transfer function of the other vehicle and the control target value of the other vehicle, and obtains a control target value used during the travel control of the vehicle on the basis of the actual output value of the other vehicle.

9. The vehicle control system according to claim 8, wherein the control device compares specification information relating to the other vehicle, which is obtained via the communication device, and the specification information relating to the vehicle to determine a characteristic difference in output characteristics or deceleration characteristics between the vehicle and the other vehicle, and obtains the control target value of the vehicle on the basis of the characteristic difference.

10. The vehicle control system according to claim 9, wherein the control device corrects the control target value of the vehicle on the basis of the characteristic difference.

11. The vehicle control system according to claim 8, wherein the control device calculates the control target value of the vehicle using the actual output of the other vehicle and information pertaining to the transfer function of the vehicle.

12. The vehicle control system according to claim 11, further comprising a measurement device that measures an actual output for the control target value of the vehicle,

wherein the control device calculates the information pertaining to the transfer function of the vehicle using the actual output of the vehicle and the control target value of the vehicle.

13. The vehicle control system according to claim 1, wherein the information pertaining to the transfer function is a time constant.

14. A vehicle control system comprising:

a communication device provided in a vehicle; and

a control device that performs travel control using information relating to another vehicle, which is received from outside the vehicle via the communication device,

wherein the communication device transmits information pertaining to a transfer function for a control target value used during the travel control, and wherein the information pertaining to the transfer function indicates a control response characteristic relative to the control target value of the vehicle, the control response characteristic is used during travel control of the vehicle and the control device performs travel control of the vehicle on the basis of the control response characteristic used during travel control of the other vehicle.

15. The vehicle control system according to claim 14, wherein the information pertaining to the transfer function is a time constant.
