  • Patent number: 10878702
    Abstract: A driving support apparatus includes a rear vehicle detection section that detects an adjacent rearward vehicle that is a vehicle traveling behind the own vehicle in an adjacent lane adjacent to the own vehicle lane. The driving support apparatus includes a control unit that acquires rear vehicle information relating to a rear vehicle traveling behind the own vehicle, on the same vehicle lane as the own vehicle. The control unit acquires boundary line information that expresses the position of a boundary line that divides the own vehicle lane and the adjacent lane. The control unit causes the own vehicle to travel so as to approach the boundary line, based on the boundary line information, when a rear vehicle is detected based on the rear vehicle information.

  • Patent number: 7761236
    Abstract: In an object recognition apparatus for a vehicle which uses intensities of reflected waves from reflecting objects to make a recognition on whether a reflecting object is a vehicle or a non-vehicle, a plurality of transmission waves are emitted to receive a plurality of reflected waves from the reflecting objects, and a decision is made as to whether or not the reflecting object producing the plurality of reflected waves is a unitary reflecting object. If the decision shows a unitary reflecting object, the highest intensity of intensities of the reflected waves from the unitary reflecting object is compared with a reference intensity to makes a decision on whether the reflecting object is a vehicle or a non-vehicle. This enables univocally making a decision for each unitary reflecting object as to whether the reflecting object is more likely to be a vehicle or to be a non-vehicle, thus improving the recognition accuracy.

  • Patent number: 7292940
    Abstract: In a vehicle control system performing collision avoiding control when a collision with a preceding vehicle cannot be avoided by normal running condition control, driving safety is improved by prompting a driver to intervene in the vehicle's control in a reliable manner. When a set switch is turned on in the “cancel” state, the transition to the “in-control, inter-vehicle distance control” sub-state occurs and an inter-vehicle distance control is performed. If a collision with a preceding vehicle cannot be avoided by the inter-vehicle distance control (if the collision alarm flag XA=1), transition to the “in-control, collision alarm” sub-state occurs and a collision alarm is generated. If the acceleration required for avoiding collision is further increased (if the collision avoiding control flag XC=1), the state transits to the “in-control, collision avoiding control” sub-state, and a collision avoiding control is performed.

  • Patent number: 6941216
    Abstract: A cruise control apparatus can control a host vehicle to run with a fixed separation from a preceding vehicle when such a preceding vehicle is detected based on received radar signals and to run at a preset fixed speed when no preceding vehicle is detected. The cruise control apparatus is configured to respond to one of a set of predetermined actions by the vehicle driver, which indicate an intention to change the vehicle speed, by making it easier or more difficult for a preceding vehicle to be detected, in accordance with whether the indicated intention may signify that an actual preceding vehicle is not being detected or may signify that a non-existent preceding vehicle is being detected and that the host vehicle speed has been reduced accordingly. Improved performance is thereby achieved by utilizing the cognitive abilities of the driver to augment the detection operation of the cruise control apparatus.

  • Publication number: 20050131614
    Abstract: When a drive control operation is set, a vehicle driving system sets a travel speed of a vehicle as a target travel speed, stores it as a set travel speed and starts drive control of the vehicle. When the drive control operation is resumed, the vehicle driving system compares the set travel speed stored in a memory and a recommended speed of a road on which the vehicle is traveling. When the recommended speed is smaller than the set travel speed and a speed limit change flag is kept reset, the vehicle driving system sets the recommended speed as the target travel speed, and restarts the drive control of the vehicle. When the recommended speed is larger than the set travel speed and at the same time the speed limit change flag is kept reset, the vehicle driving system sets the set travel speed as the target travel speed, and restarts the drive control of the vehicle.

  • Patent number: 6894605
    Abstract: Recognition result of an objective recognized as a preceding vehicle is analyzed to judge whether this objective is correctly detected as a vehicle or not. A relative acceleration is calculated based on a relative speed corresponding to the objective when analysis result shows properness of this objective as a vehicle. The relative acceleration is set to 0 when analysis result shows improperness of the objective. An inter-vehicle control amount is corrected based on the obtained relative acceleration. The distance between the preceding vehicle and the controlled vehicle is controlled based on the corrected inter-vehicle control amount.

  • Patent number: 6889140
    Abstract: A collision avoidance control system for a vehicle is provided which is designed to determine a target collision avoidance deceleration required for a system vehicle equipped with this system to bring a relative speed between the system vehicle and a target object into agreement with substantially zero without a physical collision with the target object and to determine a possibility of collision with the target object as a function of the target collision avoidance deceleration. When the possibility of collision is higher than a given threshold level, the system starts to decelerate the system vehicle. This enables the avoidance of collision with the target object at a decreased operation load on the system.

  • Patent number: 6594574
    Abstract: It judges whether a decelerator, such as fuel cut, over-drive cut, down shifting, braking, is in a temporarily unusable condition and further judges that it is necessary to drive the decelerator by the inter-vehicle control. It continues control by the inter-vehicle control means when it is necessary to drive the decelerator by the inter-vehicle control and it is judged that the decelerator is in the temporarily unusable condition. It informs the driver of data in the temporary unusable condition and further inform the driver of alarm data when the actual inter-vehicle distance is shorter than a reference. The data agrees with the alarm data. The same operation may be effected regarding accelerator. The temporarily unusable condition may be caused by continuous operation of brake pressure actuator longer than the rating.

  • Publication number: 20030045991
    Abstract: A travel control system for a subject vehicle includes a radar device for detecting preceding vehicles with respect to the subject vehicle. A controlling device operates for detecting, among the detected preceding vehicles, an interested preceding vehicle which immediately precedes the subject vehicle, and for accelerating and decelerating the subject vehicle in response to a condition of the interested preceding vehicle. A relative speed calculating device operates for calculating a relative speed between the subject vehicle and a next-lane preceding vehicle among the detected preceding vehicles. The next-lane preceding vehicle is a preceding vehicle in a lane next to a lane where the subject vehicle exists. The controlling device also operates for executing one of (1) suppression of acceleration of the subject vehicle and (2) deceleration control of the subject vehicle when the relative speed calculated by the relative speed calculating device is smaller than a prescribed negative value.
