    摘要: A vehicle includes an engine, a transmission, and a controller. The transmission includes a pressure control solenoid (PCS) valve device having a PCS and a regulating valve, a friction clutch, and a clutch piston in fluid communication with the regulating valve. The piston is operable to apply a clutch pressure to the friction clutch during a shift of the transmission. The controller is programmed to receive an acceleration value describing a lateral and/or longitudinal acceleration force of the vehicle, calculate the clutch pressure using the received acceleration value, and control an operation of the regulating valve via the PCS using the calculated clutch pressure. The acceleration value may be determined via one or more accelerometers or calculated. A method is also disclosed for compensating for acceleration in control of the regulating valve in a vehicle having a transmission that includes a friction clutch, PCS, and regulating valve.
