HYBRID VEHICLE AUTOMATIC SIMULATED SHIFTING

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.

1. A system for simulated shifting for a hybrid vehicle comprising:
a plurality of wheels; an engine for providing a torque to the plurality of wheels; a sensor configured to detect braking applied by a driver; a transmission coupled to the engine and the plurality of wheels and configured to simulate a current simulated gear and deliver an applied torque to the plurality of wheels, the applied torque being based on a requested deceleration torque that corresponds to the applied braking detected by the sensor; a memory for storing a deceleration torque for each of a plurality of simulated gears; and a processor coupled to the engine, the sensor, the transmission, and the memory, the processor configured to increase an engine speed of the engine when the requested deceleration torque exceeds a deceleration torque of a lower simulated gear, and blend the applied torque with the deceleration torque for a simulated gear of the plurality of simulated gears when or after the applied braking is decreased or no longer applied, for smoothly completing a shifting of the transmission when the hybrid vehicle transitions from deceleration to acceleration.
