  • Publication number: 20170357861
    Abstract: A vehicle driving assist apparatus executes a vehicle collision prevention control when a target object distance from a vehicle to a target object is equal to or smaller than a predetermined distance. The apparatus acquires the target object distance on the basis of a position of the target object in a camera image taken by a camera and a height of the camera in a situation that a movable load of the vehicle is a maximum load capacity.

  • Publication number: 20170349170
    Abstract: A vehicle control apparatus 10 is provided with an object detecting means detecting an object in a travel direction of a vehicle 30, a restraining means restraining a drive force of the vehicle when the object detecting means detects an object, and a jerk acquiring means acquiring a jerk in a travel direction on the basis of a behavior of the vehicle. When the accelerator of the vehicle is actuated while the vehicle is in a state in which the drive force of the vehicle is restrained, and the speed of the vehicle is lower than a predetermined value, the restraining means increases the drive force, and decreases a post-increase drive force on the basis of the jerk acquired by the jerk acquiring means.

  • Patent number: 9834210
    Abstract: A frequency of an unnecessary operation of automatic braking due to a reflected wave from a guard rail is decreased. When a collision avoidance control unit determines that an obstacle detected by a radar sensor and an own vehicle are highly likely to collide with each other, the collision avoidance control unit reads a state signal output by a parking support control unit, and determines whether or not the state signal indicates a specific state, which is a state where parallel parking support is being carried out or a state where exit support is being carried out. When the state signal indicates the specific state, the collision avoidance control unit inhibits the automatic braking.

  • Patent number: 9828028
    Abstract: When starting automatic pulling-in control, an electronic control unit calculates a temperature increase amount ?Ti of a motor caused by the execution of the automatic pulling-in control and a temperature increase amount ?To of the motor caused by the execution of automatic pulling-out control. Based on the current temperature of the motor, the temperature increase amount ?Ti, and the temperature increase amount ?To, the electronic control unit obtains a predicted temperature of the motor of a case in which the automatic pulling-out control is executed subsequent to the automatic pulling-in control. When the predicted temperature is lower than an allowable upper limit, starting of the automatic pulling-in control is permitted. When the predicted temperature is higher than or equal to the allowable upper limit, starting of the automatic pulling-in control is prohibited.
