Steering assist device
First Claim
1. A steering assist device for assisting a steering operation of a driver who drives a vehicle, the device comprising:
- a controller that controls an auxiliary torque that assists a steering of the driver, the auxiliary torque including a first auxiliary torque based on a curvature of a travel lane and a second auxiliary torque based on a position of the vehicle in the travel lane in which the vehicle travels; and
a lane change detector that detects a lane change of the vehicle, whereinwhen a lane change of the vehicle is not detected, the controller controls the auxiliary torque such that both the first auxiliary torque based on the curvature of the travel lane and the second auxiliary torque based on the position of the vehicle are provided, andupon detection of a lane change of the vehicle, the controller controls the auxiliary torque such that the first auxiliary torque based on the curvature of the travel lane is continuously provided and the second auxiliary torque based on the position of the vehicle is stopped from being provided.
