Patent number: 11932241Abstract: A driving assist system executes driving assist control for avoiding a collision with a target ahead of a vehicle. The driving assist control operates when the target exists within an assist area. A crossing target is the target crossing a roadway area ahead of the vehicle from a first side toward a second side. The assist area for the crossing target is divided into a plurality of divided assist areas including a first assist area located on the first side as viewed from the vehicle and a second assist area located on the second side as viewed from the vehicle. When the crossing target exists in the second assist area, the driving assist system decreases a control strength of the driving assist control as compared with a case where the crossing target exists in the first assist area.Type: GrantFiled: January 8, 2021Date of Patent: March 19, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoshi Nakamura, Kazuyuki Fujita, Minami Sato, Takahisa Awata

Patent number: 11787398Abstract: A driving assist system executes driving assist control for avoiding a collision with a target ahead of a vehicle. The driving assist control operates when the target exists within an assist area. First and second roadway boundaries of a roadway area are located on first and second sides as viewed from the vehicle, respectively. A crossing target is the target crossing the roadway area ahead of the vehicle from the first side toward the second side. The assist area for the crossing target is an area between an assist start boundary located on the first side as viewed from the vehicle and an assist end boundary located on the second side as viewed from the vehicle. The driving assist system sets the assist end boundary at a position between the vehicle and the second roadway boundary of the roadway area.Type: GrantFiled: January 13, 2021Date of Patent: October 17, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoshi Nakamura, Kazuyuki Fujita, Minami Sato, Takahisa Awata

Patent number: 11505185Abstract: A driving assist device for a vehicle sets a a roadway area ahead of the vehicle, detects an avoidance target existing ahead of the vehicle, and executes collision avoidance control that avoids a collision between the vehicle and the avoidance target. The collision avoidance control is more likely to be executed when the avoidance target is within the roadway area than when the avoidance target is outside the roadway area. The driving assist device detects a roadway end object and a first lane marking of a first lane in which the vehicle exists. An imaginary position is a position apart from the detected position of the roadway end object toward the first lane by a constant distance. The driving assist device sets the imaginary position or the detected position of the the first lane marking as a boundary position of the roadway area based on a predetermined condition.Type: GrantFiled: July 8, 2020Date of Patent: November 22, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoshi Nakamura, Minami Sato, Kazuyuki Fujita, Takahisa Awata

Patent number: 11305759Abstract: A vehicle control apparatus is provided with: a distance acquirer configured to obtain a distance between a first avoidance target and a second avoidance target in a longitudinal direction of a host vehicle when the first avoidance target is on one of left and right sides of the host vehicle and when the second avoidance target is on a far side of the first avoidance target and on another side of the host vehicle; and a controller configured or programmed to reduce a displacement amount in a lateral direction of the host vehicle, of a displacement in a direction of the host vehicle going away from the first avoidance target, which is to avoid the first avoidance target by the avoidance control, when the obtained distance is less than a predetermined distance, in comparison with when the obtained distance is greater than the predetermined distance.Type: GrantFiled: October 22, 2019Date of Patent: April 19, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Wataru Sasagawa, Kazuyuki Fujita, Minami Sato, Miyuki Kamatani, Takahisa Awata

Publication number: 20200231146Abstract: A driving assistance apparatus includes: an executor configured to perform at least one of a deceleration control and a steering control of a host vehicle, as an avoidance assistance control; a first determinator configured to determine whether or not the target is a vehicle; a second determinator configured to determine whether the target is a stopped vehicle, which has a possibility to move before the host vehicle passes it, or parked vehicle, which does not have a possibility to move before the host vehicle passes it, if it is determined by the first determinator that the target is a vehicle; and a controller programmed to control the executor to change a control aspect of the avoidance assistance control between if it is determined by the second determinator that the target is the stopped vehicle and if it is determined by the second determinator that the target is the parked vehicle.Type: ApplicationFiled: January 15, 2020Publication date: July 23, 2020Applicant: Toyota Jidosha Kabushiki KaishaInventors: Kumiko Miyano, Miyuki Kamatani, Wataru Sasagawa, Takahisa Awata
