  • Patent number: 11360212
    Abstract: An ultrasonic type object detection apparatus sequentially detects a distance between an ultrasonic sensor and an object in a coverage of a transmission wave at a predetermined detection cycle based on a time taken for the ultrasonic sensor to transmit the transmission wave and then to receive a reflection wave. The apparatus includes: a storage storing the distance to the object; a vehicle information acquisition device acquiring vehicle information for calculating a movement distance; a detection distance predictor predicting a next detected distance to the object based on a past detection result and the vehicle information; and a short range determinator determining whether the object is present in a short range area in which the distance between the object and the ultrasonic sensor is equal to or shorter than a short range threshold.

  • Patent number: 10106157
    Abstract: A vehicle control apparatus detects an object in a travel direction of a vehicle. The vehicle control apparatus restrains a drive force of the vehicle when an object is detected. The vehicle control apparatus acquires a jerk in a travel direction on the basis of a behavior of the vehicle. When an accelerator of the vehicle is actuated while the vehicle is in a state in which the drive force of the vehicle is restrained, and a speed of the vehicle is lower than a predetermined value. The vehicle control apparatus increases the drive force, and decreases a post-increase drive force on the basis of the acquired jerk.
