In deceleration control apparatus and method for an automotive vehicle, a deceleration control is performed in accordance with a turning travel situation of the vehicle; and an engine throttle opening angle is controlled gradually in a closure direction at...

A deceleration control apparatus for an automotive vehicle includes a target vehicle speed calculation unit (22) that calculates a target vehicle speed (V*) and a deceleration control unit (24) that performs deceleration control on the vehicle so that the ...

The present invention provides a system (210) and method for enabling a vehicle (102, 200, 302) having adaptive cruise control to reduce its speed in a turn (106, 306) according to the vehicle's position within the turn as well as ignoring objects (103, 11...

A curve's radius of a road on which a vehicle shall run is estimated based on actual speed, yaw rate, and steering angle of the vehicle. Accordingly, during a transition state of the vehicle, the curve's radius can be estimated with the actual yaw rate tak...

When a curve exists in the direction of travel of a vehicle and information for this curve is inputted from a navigation system and the shape of the actual curve in the road changes gently with respect to the curve shape of the navigation system, the chang...

The method involves determining the transverse acceleration and actual vehicle speed, determining the yaw rate, determining the float angle from the transverse acceleration, yaw rate and actual speed, comparing the float angle with a defined threshold and ...

A vehicle speed control system comprises a lateral acceleration sensor (100, 581, 582), a vehicle speed sensor (10), a target vehicle speed setting device (20, 30, 40,520) and a controller (500) arranged to calculate a correction quantity (VSUB) on the bas...

This invention relates to a method and system, in an adaptive vehicle speed control system, for controlling vehicle speed on a curved path based on the vehicle yaw rate and yaw acceleration. The method includes sensing a yaw rate of the vehicle, determinin...
