A driving assistance system for a vehicle that includes a target sensor, an operation amount sensor, a speed sensor, and an electronic control unit configured to perform pre-collision control when a predetermined control start condition is satisfied. Also, the pre-collision control is not performed, even when the predetermined control start condition is satisfied, when a permission condition has not been established by a point in time at which the predetermined control start condition is satisfied.

Driving assistance system

A driving assist apparatus executes an autonomous braking control when a predetermined autonomous stop condition becomes satisfied, executes a stopped state keeping control to keep the own vehicle stopped after stopping the own vehicle by the autonomous braking control, and terminates executing the stopped state keeping control when a predetermined stopped state keeping termination condition becomes satisfied while executing the stopped state keeping control. The driving assist apparatus executes a driving force limitation control to limit a driving force generated to move the own vehicle to a value smaller than the driving force which depends on an amount of operating the acceleration pedal when determining that the predetermined stopped state keeping termination condition is satisfied, and a mistaken pressing operation occurs. The mistaken pressing operation is an operation performed by a driver to mistakenly press an acceleration pedal with an intention to press a brake pedal.

Driving assist apparatus with autonomous braking control

When a collision avoidance target is a pedestrian or a bicycle, a driving assistance ECU performs automatic braking control. In this case, accelerator override cannot be performed. When the collision avoidance target is an automobile and when an accelerator operation amount is equal to or larger than a first operation amount threshold, the driving assistance ECU prohibits the automatic braking control. In this case, the accelerator override can be performed. When the accelerator operation amount is smaller than the first operation amount threshold, the driving assistance ECU performs the automatic braking control.

Collision avoidance assistance apparatus

Provided is a collision avoidance control apparatus including a first sensor; a second sensor; a controller configured to execute collision avoidance control; and a memory configured to, when a specific object has been detected, record information on the detected specific object, the specific object being an object which has been detected by both of the first sensor and the second sensor, in which the controller is configured to execute the collision avoidance control when determining that there is an object based on any one of the first sensor and the second sensor, and determining that the object has been already recorded as the specific object in the memory.

Collision avoidance control apparatus

When a driving assist ECU determines that a mistaken pedal operation has occurred, it starts an automatic brake control, and thereafter, ends the automatic brake control when a steering operation rate &#x3c9; is greater than a threshold &#x3c9;f (&#x3c9;&#x3e;&#x3c9;f). Whereas, when the ECU determines that the mistaken pedal operation has not occurred, it performs a steering override control and does not perform the automatic brake control, when a steering operation amount &#x3b8; is greater than a threshold &#x3b8;e or when the steering operation rate &#x3c9; is greater than the threshold.

Collision avoidance assist control apparatus

A vehicle control device comprises an operation amount sensor for measuring an operation amount of an accelerator element, an object sensor for detecting an object ahead of a vehicle, and a controller for applying a normal operation drive force which is determined depending on the operation amount to the vehicle. The controller executes an adaptive cruise control for applying a drive force required for an acceleration of the vehicle to become equal to an adaptive cruise control acceleration to the vehicle. The adaptive cruise control acceleration is an acceleration which increases as a difference between an inter-vehicle distance from the vehicle to an objective-forward-vehicle and a target inter-vehicle distance increases. When an erroneous operation start condition becomes satisfied, the controller ends the adaptive cruise control, and executes an erroneous operation related control for applying a drive force which is smaller than the normal operation drive force to the vehicle.

Vehicle control device

A driving assistance apparatus comprising a first object detecting sensor device, a second object detecting sensor device, and a control unit. The first object detecting sensor device detects an object and obtains the position and a certainty value of the object. The second object detecting sensor device detects an object and obtains the position and an object type for the object. The control unit executes collision avoidance control to avoid collision between a vehicle and a monitoring target object which is detected by the first object detecting sensor device when the certainty value of the monitoring target object is higher than a certainty threshold. If the monitoring target object is also detected by the second object detecting sensor device and its object type is a specific type, the certainty threshold is made larger.

Driving assistance apparatus

The vehicle moving control apparatus executes a following moving control to execute a target acceleration setting process and a following acceleration/deceleration process. The vehicle moving control apparatus corrects a target acceleration set by the target acceleration setting process to increase when the following moving control is executed, the target acceleration larger than zero is set by the target acceleration setting process, and an acceleration of an own vehicle is smaller than a predetermined threshold. The vehicle moving control apparatus stops the following acceleration/deceleration process and starts the steering avoidance control when a steering avoidance condition becomes satisfied as the following moving control is executed. The vehicle moving control apparatus limits the target acceleration to a value smaller than or equal to a predetermined acceleration when the steering avoidance control is stopped, and the following acceleration/deceleration process is restarted.

Vehicle moving control apparatus

A driving assistance system includes a target sensor; an operation amount sensor; a speed sensor; and an electronic control unit. The electronic control unit is configured to perform pre-collision control when a predetermined control start condition is satisfied, and not to perform, even when the predetermined control start condition is satisfied, the pre-collision control when a permission condition has not been established by a point in time at which the predetermined control start condition is satisfied. The permission condition is that the accelerating operation amount is equal to or larger than a first operation amount threshold value and the vehicle speed is equal to or less than a speed threshold value.

A pre-collision control ECU performs a pre-collision control in order to preventing a collision between the own vehicle and the object when a control start condition is satisfied. The ECU acquires a velocity threshold Vsth corresponding to a region in which the own vehicle travels based on information to specify the region. When an allowance condition has been satisfied before a timing at which the control start condition is satisfied, the ECU performs the pre-collision control. When the allowance condition has not been satisfied before the timing, the ECU does not perform the pre-collision control. The allowance condition is a condition that an accelerator operation amount is equal to or greater than an operation amount threshold and a vehicle velocity is equal to or lower than the acquired velocity threshold.

Driving support device

A driving assist apparatus includes at least one electronic control unit. The at least one electronic control unit is configured to: detect a first object and assist a collision avoidance between a vehicle and the first object existing in a traveling direction of the vehicle; determine whether a first condition that a predetermined number or more of physical objects are detected is satisfied; determine whether a second condition that the vehicle travels at a predetermined speed or lower is satisfied; determine whether a third condition that a predetermined number or more of turning operations of a steering wheel of the vehicle are performed in a predetermined time is satisfied; and determine that a road on which the vehicle is traveling is a crowded environment road, based on a determination that all of the first to third conditions are satisfied.
