Patent ID: 8165775

Claim:
A vehicle driving control system comprising: a curve state detecting device is configured to detect a curve state in a road ahead based on acquired navigation information; a target vehicle speed computing device is configured to compute a target vehicle speed for the vehicle at an upcoming curve based on the upcoming curve state, detected by said curve state detecting device, and a preset lateral acceleration set value; a target deceleration computing device is configured to compute a target deceleration at a current travel position of the vehicle based on the target vehicle speed computed by said target vehicle speed computing device; a target vehicle speed command value computing device is configured to compute a target vehicle speed command value based on the target deceleration computed by said target deceleration computing device; a road classification detecting device is configured to detect road classification of the road ahead of the vehicle; a deceleration control setting changing device is configured to change a deceleration control quantity or a deceleration control set value according to the road classification detected by said road detecting device, wherein the target vehicle speed is changed to be lower when the road classification indicates that the road ahead of the vehicle is a road for which map information has lower accuracy than when the road classification indicates that the road ahead of the vehicle is a road for which map information has a higher accuracy; and a preceding vehicle following device based on which the vehicle follows a preceding vehicle traveling ahead of the vehicle, wherein according to the classification of the road ahead of the vehicle detected by the road classification detecting device, the deceleration control setting changing device is arranged to make use of the preceding vehicle following device to control the running of the vehicle.
