1. A driving assistance apparatus that assists in driving a vehicle, comprising:
- a collision avoidance assisting section configured to perform collision avoidance assistance for avoiding a collision between a vehicle that is an assistance target and an object by prompting turning of the vehicle; and
an assistance arbitration section configured to perform arbitration between the collision avoidance assistance and driving assistance different in type from the collision avoidance assistance, whereinwhen a request for activating the driving assistance different in type from the collision avoidance assistance is detected after termination of performance of the collision avoidance assistance, and the driving assistance different in type from the collision avoidance assistance prompts turning of the vehicle in a direction conflicting with a turning direction previously prompted by the collision avoidance assistance, the assistance arbitration section performs, as the arbitration, a reduction process for reducing an assistance amount of the driving assistance different in type from the collision avoidance assistance,wherein the driving assistance different in type from the collision avoidance assistance comprises steering control of the vehicle,wherein the assistance arbitration section is further configured to suppress repeated performance of the driving assistance different in type from the collision avoidance assistance within a period of time after termination of performance of the collision avoidance assistance by performing the reduction process.

Abstract
A driving assisting section includes a collision avoidance assisting section, which performs collision avoidance assistance for avoiding collision between a vehicle to be assisted and an object by prompting turning of the vehicle. The driving assisting section further includes a lane-keeping assisting section, which performs lane keeping assistance. An assist arbitrating section arbitrates between the collision avoidance assistance by the collision avoidance assisting section and the lane keeping assistance by the lane-keeping assisting section.

1. A driving assistance apparatus that assists in driving a vehicle, comprising:
-
a collision avoidance assisting section configured to perform collision avoidance assistance for avoiding a collision between a vehicle that is an assistance target and an object by prompting turning of the vehicle; and an assistance arbitration section configured to perform arbitration between the collision avoidance assistance and driving assistance different in type from the collision avoidance assistance, wherein when a request for activating the driving assistance different in type from the collision avoidance assistance is detected after termination of performance of the collision avoidance assistance, and the driving assistance different in type from the collision avoidance assistance prompts turning of the vehicle in a direction conflicting with a turning direction previously prompted by the collision avoidance assistance, the assistance arbitration section performs, as the arbitration, a reduction process for reducing an assistance amount of the driving assistance different in type from the collision avoidance assistance, wherein the driving assistance different in type from the collision avoidance assistance comprises steering control of the vehicle, wherein the assistance arbitration section is further configured to suppress repeated performance of the driving assistance different in type from the collision avoidance assistance within a period of time after termination of performance of the collision avoidance assistance by performing the reduction process. - View Dependent Claims (2, 3, 4, 5, 6)

10. A driving assistance method for assisting in driving a vehicle, performed by a driving assistance apparatus, comprising:
-
by a collision avoidance assisting section of the driving assistance apparatus, performing collision avoidance assistance for avoiding a collision between a vehicle that is an assistance target and an object; and by an assistance arbitration section of the driving assistance apparatus, performing arbitration between the collision avoidance assistance and driving assistance different in type from the collision avoidance assistance, wherein the driving assistance different in type from the collision avoidance assistance includes driving assistance for prompting turning of the vehicle, and detecting a request for activating the driving assistance different from the collision avoidance assistance after termination of performance of the collision avoidance assistance, in a case where the driving assistance different in type from the collision avoidance assistance prompts turning of the vehicle in a direction conflicting with a turning direction previously prompted by the collision avoidance assistance, by the assistance arbitration section, performing, as the arbitration, a reduction process for reducing an assistance amount of the driving assistance different in type from the collision avoidance assistance, wherein the driving assistance different in type from the collision avoidance assistance comprises steering control of the vehicle, wherein the reduction process also suppresses repeated performance of the driving assistance different in type from the collision avoidance assistance within a period of time after termination of performance of the collision avoidance assistance.
