    摘要： A system for simulated shifting for a hybrid vehicle, the system includes a plurality of wheels, an engine, a sensor, a transmission, a memory for storing target engine speeds and deceleration torques for a plurality of simulated gears, and a processor. The engine provides a torque to the plurality of wheels. The sensor detects a requested deceleration torque. The transmission simulates a current simulated gear by delivering an applied torque, which corresponds to the requested deceleration torque, to the plurality of wheels and an engine speed corresponding to the simulated gear. The processor simulates a downshift by increasing an engine speed of the engine without changing the applied torque to the plurality of wheels when the requested deceleration torque exceeds a deceleration torque of a lower simulated gear.

    摘要： A method minimizes a driveline vibration and reduces stopping distances in a hybrid electric vehicle (HEV) having a plurality of drive wheels, a friction braking system having antilock braking system (ABS) capability, and an electronically variable transmission (EVT) with two EVT modes. The method automatically shifts the EVT to a predetermined high speed/low torque EVT mode when the ABS is active and when a calibrated maximum deceleration rate is not exceeded. An HEV has a friction braking system with ABS capability and an EVT including a plurality of modes. A controller automatically activates the friction braking ABS in response to a threshold level of slip between the drive wheels and the road surface when the brake pedal is actuated. An algorithm automatically shifts the EVT into one of the high speed/low torque EVT modes when the ABS is activated and the calibrated maximum deceleration rate is not exceeded.

    摘要： A brake control apparatus is provided that distributes an engine braking torque Tbe to the front and rear wheels in accordance with an ideal braking torque distribution to suppress and prevent the tendency for one of either the front or rear wheels to lock when the engine braking torque operates. When the road surface friction state is a low friction state and the engine braking torque operates, the brake control apparatus derives an engine braking torque Tbe and distributes the engine braking torque Tbe to the front and rear wheels in accordance with the ideal braking torque distribution. In addition, when the engine braking torque reduction amount is small, the engine drives a generator connected to the engine. When the friction state between the wheels and the road surface is not in the low friction state, the generator attached to the engine is operated as a motor that supplements driving of the engine to reduce the engine braking torque of the engine.
