<p>PROBLEM TO BE SOLVED: To provide a driving support device that can select a driving support mode according to a road environment to reduce a driver's load and has an excellent operability.SOLUTION: An LDPL mode is set to perform lane deviation prevention control with a weak ESP additional torque (Tep) for a first control zone I where a lane width W is less than a lane width threshold Ws and a vehicle speed V is less than a vehicle speed threshold V1; Either an LDPH mode to perform the lane deviation prevention control with a strong ESP additional torque (Tep) or an LKSA mode to perform lane keeping support control is set optionally for a fourth control IV where the lane width W is equal to or larger than the lane width threshold Ws and the vehicle speed V is equal to or larger than the vehicle speed threshold V1. For the other zones, a second control zone II and a third control zone III, the LDPH mode is set to perform the lane deviation prevention control with a strong ESP additional torque (Tep). Therefore, a driver's steering can be controlled relatively freely in the first control zone where the lane width W is narrow and the vehicle speed V is low, for example.</p> |
