A traveling control system for a motor vehicle includes a detector for detecting an object which exists in front of the motor vehicle to follow a vehicle traveling ahead. The system further includes a first course determination device for estimating a first course on which the motor vehicle will travel hereafter, an identification device for identifying an first target vehicle among the objects existing on the first course, and a second course estimation device for estimating, based on the first target vehicle, a second course on which the motor vehicle will travel hereafter at least while the first target vehicle is outside of the first course. The identification device identifies a second target vehicle among vehicles which travel on the first or second courses while the first target vehicle is outside of the first course.

Traveling control system for motor vehicle

In a vehicle which sets a target vehicle-interval distance, and can execute auto-cruise control for controlling the vehicle speed so as to maintain the target vehicle-interval distance, when the auto-cruise control is not executed, a vehicle-interval distance to be set by a driver is detected together with the vehicle speed at that time. A plurality of sets of the vehicle speed and vehicle-interval distance data are accumulated, and the relationship between the vehicle speed and the vehicle-interval distance is calculated. Upon execution of the auto-cruise control, a vehicle-interval distance corresponding to the vehicle speed at that time is obtained from the calculated relationship, and the obtained vehicle-interval distance is set to be the target vehicle-interval distance.

Cruise controller for vehicles

An automatic speed control system for a vehicle includes a throttle control for controlling a throttle valve opening based on a deviation between a target speed and an actual speed of the vehicle so as to accomplish the target speed. A down-shift device for making a down-shift operation in an automatic transmission, a steady judging device for judging a steady condition of the actual speed after the down-shift operation, and an up-shift device for making an up-shift operation in the automatic transmission, when a reduction of the throttle valve opening more than a predetermined value is detected, after the actual speed is judged to be in the steady condition, are provided. A proper speed control can be provided when the vehicle runs uphill, regardless of the length and/or gradient of the uphill path.
