  • Publication number: 20240140411
    Abstract: A vehicle control apparatus executes a collision avoidance control when a collision condition becomes satisfied. The collision condition includes a condition that a lap rate of the own vehicle and the object is equal to or greater than a lap rate threshold. The threshold set when the own vehicle turns, is greater than the threshold set when the own vehicle does not turn. The threshold set when a condition satisfaction period of time is equal to or greater than a predetermined period of time, is smaller than the threshold set when the condition satisfaction period of time is smaller than the predetermined period of time. The condition satisfaction period of time is a period of time that a collision probability condition continues being satisfied while the own vehicle is turning. The collision probability condition is a condition that the own vehicle has a probability of colliding with the object.
