Assistance Method of Obstacle Avoidance Maneuver by Steering Operation

Article of Honda R&D Technical Review Vol.17 No.2


Assistance types and control methods were studied, in regard to the system to assist driver maneuvers in avoiding obstacles through steering. From the principle that the driver is the focal point of driving operation, a “driver reactive” type of assistance was selected, wherein assistance begins after the driver initiates an avoidance maneuver. Actualization of a four-wheel brake control that equivalently reduces vehicle yaw inertia moment and derivative steering characteristics has enabled the development of a steering reaction torque control system, which reduces driver avoidance operation delay, as a new avoidance assistance control method. Vehicle test results have confirmed that yaw rate gain during an avoidance maneuver rises a maximum of 1.5 times, and that steering delay can be reduced by a maximum of 700ms; these have led to enhanced driver avoidance maneuvers.
