Vehicle driving assist apparatus

A vehicle driving assist apparatus of the invention starts a collision avoidance steering assist control to automatically steer the vehicle to avoid a collision of the vehicle with the obstacle in response to a driver performing a collision avoidance steering operation for avoiding the collision when there is a possibility that the vehicle collides with the obstacle. The vehicle driving assist apparatus cancels the collision avoidance steering assist control in response to the driver performing a counter collision avoidance steering operation against automatically steering the vehicle intended to be achieved by the collision avoidance steering assist control after a first predetermined time elapses from starting the collision avoidance steering assist control. The vehicle driving assist apparatus continues the collision avoidance steering assist control until the first predetermined time elapses from starting the collision avoidance steering assist control even when the driver performs the counter collision avoidance steering operation.
