Abstract
A vehicle speed control system includes a first electronic control unit for transmitting a difference between actual and target vehicle speeds and control constants that vary depending on the vehicle speed difference when it determines fulfillment of vehicle speed control conditions, and a second electronic control unit for performing the vehicle speed control based on the vehicle speed difference and control constants received through a communication line. Change of the control constants for adjustment of a vehicle speed control function of the system can be easily carried out by changing the control constants stored in the first electronic control unit.
Claims11
A vehicle speed control system which includes first control means for transmitting a fulfillment signal when it determines that conditions for vehicle speed control are fulfilled, vehicle speed detecting means for detecting an actual vehicle speed, target vehicle speed setting means for setting a target vehicle speed, second control means for performing vehicle speed control to make the actual vehicle speed coincide with the target vehicle speed, and communication line means for connecting the first control means and the second control means to permit information transfer therebetween, comprising:
- said first control means storing control constants for the vehicle speed control, and
- said second control means performing the vehicle speed control when it receives the fulfillment signal and required control constants from said first control means through said communication line means.
A vehicle speed control system which includes vehicle speed detecting means for detecting an actual vehicle speed, vehicle speed limit setting means for setting a vehicle speed limit, first control means for transmitting a fulfillment signal when it determines based on the actual vehicle speed and the vehicle speed limit that conditions for vehicle speed restriction are fulfilled, second control means for performing vehicle speed control to restrict the actual vehicle speed up to the vehicle speed limit, and communication line means for connecting the first control means and the second control means to permit information transfer therebetween, comprising:
- said first control means storing control constants for the vehicle speed control, and
- said second control means performing the vehicle speed control when it receives the fulfillment signal and required control constants from said first control means through said communication line means.
