What Are the Throttle Control Techniques for Dual-Clutch Transmissions?
1 Answers
The throttle control techniques for dual-clutch transmissions are as follows: Always Shift to Neutral When Stopped: Drivers accustomed to AT or CVT transmissions often make the mistake of holding down the brake pedal at a red light and only releasing it when ready to move. This habit is detrimental to dual-clutch transmissions. The working principle of a dual-clutch transmission is similar to that of a manual transmission. When stopped, the clutch is not fully disengaged. Due to the purely mechanical connection, energy has nowhere to go when the brake is held down for extended periods while in gear. Some of this energy wears the clutch discs, while the excess converts into heat. Once the dual-clutch's overheating protection kicks in, the transmission must rest... This explains why dual-clutch transmissions often fail in heavy traffic. The solution is simple: treat the dual-clutch like a manual transmission—shift to Neutral (N) when stopped to disengage power output and give the transmission a break. Use Light Throttle When Starting: Light acceleration is recommended because, in the original design, the dual-clutch's maximum torque output is in 2nd gear. You'll notice that 1st gear is fleeting. Wait until a gentle throttle smoothly transitions to 2nd gear before applying heavier acceleration—this ensures no issues. Frequently Use Manual Mode: Dual-clutch transmissions have adaptive programming. Regular use of manual mode allows the transmission to develop a memory effect and operate based on this memorized pattern. This personalizes the driving experience and helps reduce shift frequency, lowering the probability of malfunctions.
