How to Properly Use CVT at Red Lights?
1 Answers
When waiting at traffic lights with a CVT transmission, you can keep the brake pedal depressed continuously; however, if the waiting time is excessively long, you may choose to shift to Neutral (N) gear and engage the parking brake. Below is an introduction about CVT transmissions: 1. CVT transmissions typically incorporate a torque converter, which contains a clutch to control the engagement of the torque converter. The clutch generally operates in three states: fully disengaged, partially engaged, and fully engaged. During steady throttle and vehicle speed, the clutch remains fully engaged, ensuring smooth driving and precise throttle control. When the throttle is adjusted, the clutch enters a fluctuating state, alternating between partial and full engagement. 2. When the vehicle is stationary, even though it remains in Drive (D) gear, the engine control unit commands the clutch to fully disengage. In this state, the engine drives the torque converter's impeller via the input shaft, while the transmission output shaft connected to the turbine remains stationary under braking force. The energy is absorbed by the fluid flow between these components, preventing any impact or friction within the transmission. Consequently, there is no mechanical friction that could elevate temperatures, leading to transmission fluid degradation or component damage.
