Driving assistance apparatus
First Claim
1. A driving assistance apparatus comprising:
- a plurality of sensor devices mounted in a host vehicle;
an attention calling device configured to call attention of a driver of the host vehicle; and
at least one electronic control unit configured toacquire, based on detection outputs of the sensor devices, host vehicle information including parameters related to a vehicle speed of the host vehicle and a yaw rate of the host vehicle,acquire, based on the detection outputs of the sensor devices, object information including a relative position of an object present around the host vehicle with respect to the host vehicle, a traveling direction of the object, and a speed of the object,estimate, based on the host vehicle information, an expected path through which the host vehicle is expected to pass,determine, based on the object information, whether or not a target object that is an object likely to cross the expected path within a threshold time period is present,determine, based on at least the object information, whether or not there is a front space in front of the host vehicle, front space being a space allowing the target object to pass in front of the host vehicle,generate a request signal so as to call attention of the driver of the host vehicle, when the electronic control unit determines that the target object is present, and that there is the front space,forbid generation of the request signal when the electronic control unit determines that the target object is present, and that there is no front space, andcontrol the attention calling device to call attention of the driver in response to generation of the request signal.

Abstract
A driving assistance apparatus includes a plurality of sensor devices mounted in a host vehicle, an attention calling device configured to call attention of a driver of the host vehicle, and at least one electronic control unit. The at least one electronic control unit acquires host vehicle information, acquires object information, estimates an expected path through which the host vehicle passes, determines whether or not a target object is present, determines whether or not there is a front space in front of the host vehicle based on the object information, generates a request signal so as to call attention of the driver of the host vehicle, forbids generation of the request signal when the electronic control unit determines that the target object is present, and that there is no front space, and controls the attention calling device to call attention of the driver.
