Claim 0:
1. A driving assistance apparatus comprising:
a brake device including a brake actuator that causes a friction brake mechanism to apply a brake force to a host vehicle;
a drive force generating device that generates a drive force applied to said host vehicle; and
a control unit storing executable program instructions that when executed cause the control unit to:
perform a lane departure suppression control so as to prevent said host vehicle from departing from a traveling lane, by giving an alert to a driver of said host vehicle or executing a steering control, when said host vehicle is determined to be about to depart from said traveling lane;
obtain a collision indicative value indicative of an impact caused by a collision of said host vehicle with an object;
determine that a low impact collision has occurred if the collision does not cause an air bag of said vehicle to be inflated and if said collision indicative value exceeds a threshold;
determine whether or not a low impact collision time point at which said low impact collision is determined to have occurred is in a first period that contains a duration in which said alert to said driver of said host vehicle is being given by said lane departure suppression control or said steering control is being executed by said lane departure suppression control; and
perform a secondary collision damage mitigation control to let said brake device apply said brake force to said host vehicle or impose a limitation on said drive force generated by said drive force generating device, when it is determined that said low impact collision time point is in said first period; wherein said control unit is configured not to perform said secondary collision damage mitigation control, when it is determined that said low impact collision time point is not in said first period.
