20190391259 | INTER-VEHICLE DISTANCE CONTROL DEVICE - An inter-vehicle distance control device that achieves inter-vehicle distance control satisfying the driver includes a preceding vehicle velocity computation part that computes a preceding vehicle velocity on the basis of a host vehicle velocity and a relative velocity of the preceding vehicle, a target inter-vehicle setting art that sets a target inter-vehicle distance from the preceding vehicle on the basis of the preceding vehicle velocity, a target track generator that generates a target track and a target track differential, the target track defining a time history lasting until the initial value of the inter-vehicle distance reaches the target inter-vehicle distance, and a feedback controller that computes a feedback acceleration command by multiplying a deviation of the inter-vehicle distance from the target track and a deviation of the relative velocity from the target track differential value by a gain. The feedback acceleration command is output as an acceleration command. | 2019-12-26 |
20190391260 | METHOD FOR MONITORING THE SURROUNDINGS OF A VEHICLE - A method for monitoring the surroundings of a vehicle, the surroundings behind the vehicle being detected with the aid of ultrasonic sensors and with the aid of at least one imaging sensor, a warning signal being output when an object that has a distance to the vehicle smaller than a predefined minimum distance is detected with the aid of ultrasonic sensors, a trailer of the vehicle being recognized with the aid of the imaging sensor, and the warning signal not being output when the object is the trailer recognized by the imaging sensor. | 2019-12-26 |
20190391261 | SYSTEM AND METHOD FOR ESTIMATING TRAJECTORY OF OBJECT IN 3 DIMENSIONS - The present invention relates to an object trajectory estimation technology.
