Abstract: An information processing apparatus mounted on a first vehicle receives vehicle information including information about a travel state of a second vehicle, from the second vehicle by vehicle-to-vehicle communication. Furthermore, when the vehicle information is received from the second vehicle, the information processing apparatus receives, from a server apparatus, target information that is acquired by the second vehicle and that is transmitted by the second vehicle to the server apparatus.

Abstract: An information processing apparatus mounted on a vehicle includes a controller configured to be capable of performing driving assist control and notification control. In a case where the vehicle receives another-vehicle information including information about a travel state of another vehicle from another vehicle by vehicle-to-vehicle communication, the controller performs the driving assist control based on the another-vehicle information. Furthermore, in a case where the vehicle receives the another-vehicle information not by vehicle-to-vehicle communication but from a server apparatus that performs communication with another vehicle, the controller performs the notification control based on the another-vehicle information without performing the driving assist control based on the another-vehicle information.

Abstract: When an own vehicle is highly likely to collide with an obstacle, a notification of prompting a driver to carry out a collision avoidance operation is appropriately given. When an output request for collision avoidance support information exists, a notification ECU notifies of the collision avoidance support information irrespective of absence/presence of an output request for vehicle-infrastructure cooperation support information. When the output request for the collision avoidance support information does not exist and the output request for the vehicle-infrastructure cooperation support information exists, the notification ECU notifies of the vehicle-infrastructure cooperation support information.

Abstract: A vehicle control apparatus of the invention determines whether or not an informing condition is satisfied. The informing condition becomes satisfied when a particular situation regarding an own vehicle traveling that a driver of the own vehicle should be alerted occurs. The apparatus executes an informing control for alerting the driver when the informing condition is satisfied and executes a cruise control for causing the own vehicle to travel when a cruise condition is satisfied. The apparatus executes an adjustment process for forbidding the informing control and permitting the cruise control when both the informing and cruise conditions are satisfied and the own vehicle is accelerated or decelerated by the cruise control and for permitting both the informing and cruise controls when both the informing and cruise conditions are satisfied and the own vehicle is not accelerated nor decelerated by the cruise control.

Abstract: The invention relates to a vehicle control apparatus configured to perform a first particular situation informing for providing information depending on a first particular situation regarding a vehicle traveling where a driver of a vehicle should be alerted and the vehicle should continue to be stopped when determining that a first particular situation occurs and perform a simultaneous operation informing for providing information depending on a simultaneous operation situation where both of an acceleration operator and a brake operator of the vehicle are operated when determining that the simultaneous operation situation occurs. The vehicle control apparatus is configured to perform the first particular situation informing without performing the simultaneous operation informing when determining that both of the first particular situation and the simultaneous operation situation occur.

Abstract: A vehicle control apparatus of the invention is applied to a vehicle having at least one device configured to acquire a road situation information from an outside of the vehicle. The apparatus determines whether or not a particular situation regarding a vehicle traveling occurs on the basis of the road situation information. The particular situation being a situation that a driver of the vehicle should be alerted. The apparatus can perform an informing for alerting the driver and execute a cruise control for causing the vehicle to travel automatically without an operation of an acceleration operator of the vehicle. The apparatus performs the informing when the particular situation occurs, the cruise control is not executed and the acceleration operator is operated. The apparatus performs the informing when the particular situation occurs and the cruise control is executed, independently of whether or not the acceleration operator is operated.

Abstract: A limited display space provided in a vehicle is used to effectively provide driving support information to a driver. When a notification condition for driving support information is satisfied, an information processing unit generates the driving support information, and determines whether the driving support information is prioritized driving support information or non-prioritized driving support information. When the driving support information is the prioritized driving support information, the information processing unit transmits an output request for the driving support information to an HUD ECU. As a result, the driving support information is displayed on a head-up display. On the other hand, when the driving support information is the non-prioritized driving support information, the information processing unit transmits an output request for the driving support information to a meter ECU. As a result, the driving support information is displayed on a meter display.

Abstract: An intersection information acquisition unit acquires detection information by an object detection sensor including at least one of a vehicle detection sensor and a human detection sensor. A support processor performs driving support processing for outputting an alarm when the support processor determines that an own vehicle intends to cross the opposite lane and determines based on the acquired detection information that an object exists or the object is approaching in a direction in which the own vehicle travels to cross the opposite lane at the intersection. The support processor performs the driving support processing when the intersection information acquisition unit acquires detection information by the vehicle detection sensor. On the other hand, the support processor does not perform the driving support processing when the intersection information acquisition unit acquires detection information by the human detection sensor and does not acquire detection information by the vehicle detection sensor.

Abstract: An alarm controller generates an alarm output instruction when an own vehicle state determination unit determines that an own vehicle intends to cross the opposite lane at an intersection, and the object state determination unit determines that an oncoming vehicle or a person exists or moves in a direction in which the own vehicle crosses the opposite lane at into the intersection. A shift position detector detects a shift lever position. When the shift position detector detects that a shift lever is in a parking position or a reverse position, the alarm controller does not generate the alarm output instruction.
