  • Publication number: 20180174461
    Abstract: A vehicle control device generates a fusion target by fusion of a radar target of an object ahead of the own vehicle acquired as a reflected wave of a carrier wave and an image target of the object acquired by image processing of an acquired image of a region ahead of the own vehicle and performs vehicle control of the own vehicle for the object detected as the fusion target. The vehicle control device determines whether a state where the object is detected with the fusion target has transitioned to a state where the object is detected with only the radar target; determines whether a distance to the object is a predetermined short distance when the state is determined to have transitioned to the state where the object is detected with only the radar target; and performs the vehicle control for to the object when the distance to the object is determined to be the predetermined short distance.

  • Publication number: 20180154892
    Abstract: A vehicle control apparatus accumulates a history of timings of avoidance operations performed by a driver of with respect to objects that are at prescribed distances ahead of a host vehicle, and calculates a distribution of the timings of the avoidance operations. Based on the distribution of the timings of the avoidance operations, the vehicle control apparatus sets the output timing of a warning to the driver such that interference does not occur between the avoidance operation and an avoidance operation that is actually performed by the driver, and furthermore the vehicle control apparatus judges the risk of a collision with the host vehicle, with the judgement based on the position of an object that is ahead of the host vehicle, and changes the output timing of the warning based on results of the judgement of risk.

  • Publication number: 20180118202
    Abstract: A vehicle control apparatus acquires a relative position of an object to an own vehicle, the object being located ahead of the own vehicle in a traveling direction. The vehicle control apparatus acquires yaw rate information including at least one value of a yaw rate and a yaw rate differential value of the own vehicle. The vehicle control apparatus acquires steering information including at least one value of a steering angle and a steering angle speed of the own vehicle. The vehicle control apparatus activates, on a basis of the relative position, a safety unit for avoiding a collision with the object. In the case where an absolute value of the yaw rate information is greater than a first threshold and an absolute value of the steering information is greater than a second threshold, the vehicle control apparatus causes the safety unit to be less likely to be activated.

  • Publication number: 20180122242
    Abstract: A vehicle control apparatus activates a safety device for avoiding a collision of an own vehicle with a target or reducing damage caused by the collision. The vehicle control apparatus sets an activation condition for the safety device. The vehicle control apparatus determines whether each of a plurality of correction conditions for the activation condition is satisfied. The vehicle control apparatus determines whether to activate the safety device on the basis of the activation condition. The vehicle control apparatus sets the activation condition by correcting a reference condition on the basis of a correction value for a satisfied correction condition, and correcting the corrected reference condition on the basis of a correction value (destination correction value) for each destination.

  • Publication number: 20180118204
    Abstract: A vehicle control apparatus is provided which includes position detecting means for detecting a position of a detected target using reflection information derived from a radar device 21, first determining means for determining whether the detected target is expected to be an obstacle not based on an intensity of a received reflected wave contained in the reflection information, and second determining means for determining whether an obstacle exists at the position, as detected by the position detecting means, or not using the image information. When the second determining means determines that the obstacle exists, and when a distance between an own vehicle and the detected target is smaller than a given threshold value, the detected target is determined as a target with which collision should be avoided regardless of a result of determination made by the first determining means.

  • Publication number: 20180096088
    Abstract: In a capacitor equivalent circuit model for when a DC voltage is superimposed on a signal, using an equivalent circuit for when the DC voltage is not applied as a baseline, a voltage-controlled current source or voltage source that adjusts the signal in accordance with the superimposed DC voltage is substituted with a portion that represents the capacitance of the equivalent circuit. The voltage-controlled current source or voltage source is then modeled using a current or voltage approximation formula that describes the change in the signal resulting from the changes in the characteristics of the capacitor due to superimposition of the DC voltage, and a device that represents the capacitance of the equivalent circuit behaves similar to a variable device due to superimposition of the DC voltage. This approximation formula reduces computational load on a simulator and prevents issues such as divergence.

  • Publication number: 20180079408
    Abstract: An object detection apparatus acquires a lateral position which is a relative position of a target to the own vehicle, and determines that a first target is present, as the target, ahead of the own vehicle and that a second target is present between the first target and the own vehicle. The object detection apparatus determines, based on the lateral position of the first target and a limiting value which indicates a width in the lateral direction, whether the first target is present on a traveling course of the own vehicle. The object detection apparatus sets the limiting value such that when the second target is not present, sets as the limiting value, a predetermined reference value, and when the second target is present, sets as the limiting value, a value different from the reference value.
