What does 9-speed manual-automatic transmission mean?

[McIvan]

9-speed manual-automatic transmission refers to a gearbox that combines 9-speed manual and automatic shifting. As the name suggests, "manual-automatic" combines manual and automatic gear shifting methods in cars. Literally, it means a car has both manual and automatic gear functions. The automatic transmission includes a manual-automatic transmission, which is an automatic transmission that allows self-shifting. The manual mode in a manual-automatic transmission differs from a purely manual car. Although it has a clutch mechanism, the driver does not need to operate it, meaning it has an automatic clutch. A regular automatic transmission has neutral, drive, hill-climb first gear, hill-climb second gear, and reverse. In addition to these, a manual-automatic transmission also allows the driver to manually shift gears, usually marked as "+" and "-". A regular automatic transmission has neutral, drive, hill-climb first gear, hill-climb second gear, and reverse. In addition to these, a manual-automatic transmission also allows the driver to manually shift gears. The manual-automatic transmission does not have a clutch pedal because it is also an automatic transmission, and the clutch is not controlled by the driver. When using the manual mode in a manual-automatic car, simply switch to manual mode and adjust the gears up or down based on speed changes. If the speed does not match the current gear, the gear will automatically downshift; if the speed exceeds the current gear, the driver must manually upshift. The manual-automatic transmission combines manual and automatic shifting in cars. This transmission combines the advantages of automatic and manual transmissions, minimizing power loss in the shifting system. The manual mode allows the driver to freely adjust gears and RPM based on their preference. The manual mode in a manual-automatic transmission differs from a purely manual car. Although it has a clutch mechanism, the driver does not need to operate it, meaning it has an automatic clutch. When using the manual mode in a manual-automatic car, simply switch to manual mode and adjust the gears up or down based on speed changes. If the speed does not match the current gear, the gear will automatically downshift; if the speed exceeds the current gear, the driver must manually upshift. Working Principle: Structurally, the manual-automatic transmission mainly consists of a regular gearbox (similar to a manual transmission), an electronically controlled clutch, an automatic shifting mechanism, and an electronic control unit. The electronically controlled clutch automatically engages or disengages the clutch as needed, controlled by the transmission ECU, which operates a stepper motor to move the clutch fork. The automatic shifting mechanism automatically selects the appropriate gear, usually controlled by two stepper motors managed by the transmission ECU. The gear lever setup is similar to a regular automatic transmission, with no clutch pedal. This transmission essentially uses automatic control to simulate manual shifting. During normal driving, it operates similarly to a hydraulic automatic transmission, except when stopped, the clutch is disengaged. Therefore, when parked on a slope, the brake must be applied to prevent rolling. In manual mode, it feels like driving a manual car with direct power delivery, eliminating the need to operate the clutch and allowing skip-shifting (jumping gears).
