摘要： An electrical regeneration and vehicle deceleration control method includes operating an electrified powertrain in normal or maximum regeneration modes associated with lesser and greater electrical regeneration and vehicle deceleration rates, respectively, receiving an input from a driver of the vehicle indicative of a request to enable the maximum regeneration mode, detecting a status indicative of an availability of the maximum regeneration mode, and in response to receiving the request and based on the status of the maximum regeneration mode and a current vehicle deceleration rate: (i) operating the electrified powertrain in either the maximum regeneration mode or a normal regeneration mode, (ii) selectively outputting a message to the driver indicative of the status of the maximum regeneration mode, and (iii) selectively commanding a hydraulic brake system of the vehicle to generate brake force based on a driver-expected vehicle deceleration rate associated with the operative regeneration mode.

摘要： A hybrid powertrain includes a torque provider, an automatic transmission without a torque converter, and a transfer case configured for providing four wheel drive low range. A controller receives a signal indicative of the transfer case being in low range and determines if brake pedal torque is indicative of a brake pedal being released and, if so, commands engagement of a launch clutch of the transmission up to maximum creep torque capacity at a predetermined maximum gradient. The controller determines when torque provider speed is synchronized with vehicle creep speed, and upon such determination, controls the launch clutch to fully engage to a lock up state to mimic behavior of engagement of a manual transmission gear when the hybrid powertrain is in low range to thereby substantially eliminate a time lag associated with automatic transmissions having a torque converter or a constantly slipping launch clutch.

摘要： Hybrid-electric powertrain control systems and methods include a set of sensors configured to measure a set of operating parameters of a set of components of the hybrid-electric powertrain that are each a constraint on minimum/maximum motor torque limits for the electric motors thereby collectively forming a set of constraints and a controller configured to perform a linear optimization to find the best engine torque values that are attainable subject to a set of constraint inequalities as defined by current vehicle state and as monitored by the set of sensors, and control the hybrid-electric powertrain based on the best engine torque values to avoid excessive torque commands that could damage physical components of the hybrid-electric powertrain and/or could cause undesirable noise/vibration/harshness (NVH) characteristics.
