Brake activated torque disable in hybrid electric vehicles

摘要

An interface for interfacing an accelerator control input, a service brake control input, and a parking brake control input with a hybrid electric vehicle's electric control system that controls propulsion of the vehicle by controlling the motor torque output of an electric traction drive motor that drives driven wheels of the vehicle. The application of either the service brakes or the parking brake concurrent with the accelerator pedal being at non-idle causes the interface to override the motor torque being requested by the accelerator control input in favor of a zero motor torque request to the control system.
