What do D+ and D- gears mean?
1 Answers
Automatic transmission D+ and D- are manual modes. When driving in D gear, you can push the gear lever to the right into the D+/D- position. At this time, the gear lever is between D+ and D-, then push forward (D+) once or pull backward (D-) once, which means increasing or decreasing one gear (the dashboard displays the gear number digitally), and can be continuously increased or decreased. The following is an introduction to automatic transmission cars: 1. No clutch pedal: Automatic transmission cars usually use hydraulic transmission devices to replace the mechanical clutch of manual transmission cars, so there is no clutch pedal. 2. Starting principle: When the engine speed is low, the torque transmitted by the liquid is limited and insufficient to push the car forward. When the control handle is placed in the forward gear and the brake pedal is released, as the accelerator is pressed and the engine speed increases, the transmitted torque increases to push the car forward. 3. Convenient operation: When driving a modern automatic transmission car, the driver only needs to control the accelerator pedal. The computer analyzes the signals of engine throttle opening and vehicle speed collected by some sensors and automatically controls the gear shift or makes the transmission shift into different gears.
