Abstract: A system and method for a host vehicle for generating distance between a host vehicle and a target object traveling in the predicted path of the host vehicle, and velocity data as to the velocity of the target object. When a target object is detected, distance data is set to correspond to a measured distance value, velocity data is set to correspond to a value based on a measured value of the relative velocity of the target object and the velocity of the host vehicle, and stored. When the target object ceases to be detectable when the host vehicle is traveling in a curve, a value of the distance between the host vehicle and the target object is repeatedly estimated based on latest distance and velocity data stored and the velocity of the host vehicle, whereupon the distance data is set to correspond to the estimated value and stored.

Abstract: An adaptive cruise control system and a method for controlling the velocity of a host motor vehicle. An object detecting device is capable of simultaneously detecting several target objects. A separate control order is generated for each detected target object for influencing engine controls and brake controls of the host vehicle to control the velocity of the host vehicle. Control orders generated for several simultaneously detected target objects are then compared and the most restrictive control order among these is selected. At least one control signal based on the selected control order is then sent to at least one of the engine controls and the brake controls of the host vehicle to control the velocity of the host vehicle in accordance with the selected control order.

Abstract: A data generating system and a method to be used in a host vehicle for generating distance data as to the distance between the host vehicle and a target object travelling in the predicted path of the host vehicle and velocity data as to the velocity of the target object. When a target object is detected, the distance data is set to correspond to a measured distance value, the velocity data is set to correspond to a value determined based on a measured value of the relative velocity of the target object and the velocity of the host vehicle, and these data are stored in a memory. When the target object ceases to be detectable at the same time as the host vehicle is travelling in a curve, a value of the distance between the host vehicle and the target object is repeatedly estimated based on the latest distance and velocity data stored in the memory and the velocity of the host vehicle, whereupon the distance data is set to correspond to the estimated value and stored in the memory.
