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.

Driving assist system

A first vehicle includes a communication device configured to send and receive V2V information, a memory configured to store the V2V information, and a processor configured to perform abnormal traveling determination processing. A second vehicle includes a communication device configured to send and receive the V2V information, a memory configured to store the V2V information and driving environment information on the second vehicle, and a processor configured to perform objective determination processing. In the objective determination processing, whether the first vehicle is traveling abnormally is objectively determined based on the driving environment information on the second vehicle. The determination result of the objective determination processing is sent to the first vehicle. In the abnormal traveling determination processing, whether the first vehicle is traveling abnormally is determined based on this determination result. When the first vehicle is determined to be traveling abnormally, emergency vehicle control is performed for the first vehicle.

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.

A traffic light management system that manages display of traffic lights includes a communication device, a control device, and a map database. The control device performs emergency control of the display when abnormal traveling information indicating the information on an abnormally traveling vehicle is included in the information received from a communication vehicle. In the emergency control, the control device predicts a future trajectory of the abnormally traveling vehicle based on the abnormal traveling information. Next, the control device generates the emergency control signal for temporarily prohibiting passage at an intersection and a crosswalk on a road along the future trajectory based on the map information and the future trajectory. After that, the control device sends the emergency control signal to controlled traffic lights. The controlled traffic lights are each a traffic light at the intersection and the crosswalk on a road along the future trajectory.

A deterioration determination apparatus is usable with an ammonia sensor that includes an ammonia element portion that includes, a solid electrolyte, an ammonia electrode, and a reference electrode. The deterioration determining apparatus compares a first evaluation value and a second evaluation value, and determines whether deterioration has occurred in the ammonia element portion of the ammonia sensor at an evaluation time or subsequent to the evaluation time. The first evaluation value is based on a first sensor current obtained when a DC voltage is applied between the ammonia electrode and the reference electrode of the ammonia element portion at an initial time that is during an initial use period of the ammonia sensor. The second evaluation value is based on a second sensor current obtained when the DC voltage is applied between the ammonia electrode and the reference electrode subsequent to the initial period of use of the ammonia sensor.

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.
