  • Publication number: 20180201259
    Abstract: A vehicle control apparatus is mounted in a vehicle and includes: an object detecting unit that detects an object in a travelling direction of the vehicle; and a suppressing unit that suppresses driving force of the vehicle when the object detecting unit detects the object. The suppressing unit performs a first process to gradually increase the driving force when a command to move in the travelling direction is issued and the vehicle is stopped in a state in which the driving force of the vehicle is suppressed, and after the vehicle starts to move from the stopped state, performs a second process to gradually increase the driving force with an amount of increase per time in the driving force that is less than that in the first process.

  • Publication number: 20180170368
    Abstract: A driving assistance apparatus operates a collision avoidance apparatus that is mounted in a vehicle based on a distance to an object that is positioned ahead of the vehicle in a travelling direction. The driving assistance apparatus includes: a resistance determining unit that determines whether or not running resistance that suppresses rolling of wheels forward in the travelling direction of the vehicle is present; an operation determining unit that determines whether or not an accelerator operation by a driver of the vehicle is being performed; and a distance setting unit that sets an operation distance that is a distance at which the collision avoidance apparatus is operated. When the resistance determining unit determines that the running resistance is present and when the operation determining unit determines that the accelerator operation is being performed, the distance setting unit sets the operation distance to a value that is less than that when the running resistance is not present.

  • Publication number: 20180156916
    Abstract: A driving assistance device that detects an object around the own vehicle by using an ultrasonic sensor mounted on the own vehicle and performs driving assistance control of the own vehicle. The driving assistance device drives an oscillator of the ultrasonic sensor so that ultrasonic waves are transmitted from the oscillator. The driving assistance device acquires a duration and a frequency of reverberation occurring in association with driving of the oscillator. The driving assistance device determines, on a basis of the acquired duration and frequency of the reverberation, whether an oscillation characteristic of the reverberation has changed. The driving assistance device changes, on a basis of a result of determination of the oscillation characteristic of the reverberation, at least one execution mode of the driving assistance control and determination of abnormality in the driving assistance control.

  • Publication number: 20180154890
    Abstract: A vehicle control ECU is configured to determine the presence or absence of an object ahead of a vehicle in its traveling direction. The vehicle control ECU is configured to, if an object has been detected, raise a driving force command value in the vehicle in a stepwise manner such that the driving force command value does not exceed a request value determined based on an accelerator position designated by a driver until the speed of the vehicle reaches a predetermined speed, and lower the driving force command value after the speed of the vehicle reaches the predetermined speed. The vehicle control ECU is configured to calculate the slope of a road on which the vehicle runs. The vehicle control ECU is configured to change the increase rate per time for raising the driving force command value based on the slope.

  • Patent number: 9953532
    Abstract: An obstacle warning apparatus in a vehicle specifies a position of an obstacle relative to the vehicle based on a detection result by an obstacle sensor. A warning determination section determines whether a warning about the obstacle needs to be executed, based on the specified position of the obstacle. The warning determination section determines that the warning about the obstacle does not need to be executed when an overlap determination section determines that a vehicle range overlaps with a range where the obstacle exists.

  • 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.

  • Publication number: 20170322299
    Abstract: An in-vehicle object determining apparatus cooperates with an obstacle sensor unit, which detects an obstacle at a first time. An estimated detected state is calculated as a detected state of the obstacle estimated to be detected by the obstacle sensor unit at a second time after a lapse of a predetermined time period from the first time, on condition that the obstacle is assumed to be under stationary state, based on (i) a vehicle-relative position of the obstacle detected at the first time, (ii) a sensor position of the obstacle sensor unit, and (iii) a vehicle position change during a period from the first time to the second time. It is determined that the obstacle is a moving object based on a discrepancy between the estimated detected state of the obstacle and a real detected state of the obstacle actually detected by the obstacle sensor unit at the second time.

  • Publication number: 20170242121
    Abstract: A lateral distance sensor diagnosis apparatus cooperating with a lateral distance sensor in a vehicle includes a travel enabled distance acquisition section and a diagnosis test section. The travel enabled distance acquisition section determines whether the vehicle is estimated to have contact with an object detected by the lateral distance sensor, based on a distance detected by the lateral distance sensor and a present steering angle. When determining that the vehicle is estimated to have contact with the detected object, the travel enabled distance acquisition section acquires a travel enabled distance based on a distance detected by the lateral distance sensor. The diagnosis test section determines that the lateral distance sensor fails to operate normally when a movement distance becomes greater than the travel enabled distance under state where the steering angle is an angle causing the vehicle to have contact with an object detected by the lateral distance sensor.
