ABSTRACT:
A control system for controlling a throttle of a vehicle during a virtual bumper event is provided. The system includes: an enable module that selectively enables torque reduction based on at least one of a torque reduction request and an object detection signal; a throttle override module that overrides a pedal request by commanding a throttle position to reduce torque when the torque reduction is enabled; and a throttle learn module that commands the throttle position to gradually increase torque based on a position indicated by the pedal request when torque reduction is no longer enabled.
