LANE KEEPING ASSIST APPARATUS

摘要

In a state where steering required torque is outputted (S1: YES), the steering required torque is canceled (S12) based on the fact that a state of driver torque being inputted has continued (S11: YES). A cancellation delay time, which represents the length of time from when the driver torque is inputted until the steering required torque is canceled, is set to be shorter when the driver torque is higher than or equal to a timer-ON threshold 2 than when the driver torque is between a timer-ON threshold 1 and the timer-ON threshold 2. Consequently, in the case where a steering wheel is quickly turned by a driver and thus high torque is inputted to the steering wheel, control torque will be canceled in a short time and thus steering will be performed in quick response to the steering wheel operation of the driver. As a result, an uncomfortable feeling caused to the driver will be suppressed.

1. A lane keeping assist apparatus (10, 10A) installed on a vehicle, the lane keeping assist apparatus comprising:
a control torque outputting unit (12, 12A) that outputs control torque for keeping the vehicle in a traveling lane; and a driver torque detection unit (11) that detects driver torque, the driver torque being torque inputted by a driver of the vehicle to a steering wheel of the vehicle, characterized in that in a state of outputting the control torque, the control torque outputting unit stops the output of the control torque based on the detection of the driver torque, and the control torque outputting unit varies, according to the driver torque detected by the driver torque detection unit, a time from when the driver torque is inputted until the output of the control torque is stopped.
