What are the techniques for coordinating the clutch and accelerator in Driving Test Subject 3?
1 Answers
Driving Test Subject 3 clutch and accelerator coordination techniques are as follows: when shifting from a high gear to a low gear, perform the following actions swiftly—first, press the clutch pedal while simultaneously releasing the accelerator pedal, move the gear lever to the neutral position, quickly lift the clutch pedal while rapidly pressing the accelerator pedal once and then immediately releasing it (this 'empty throttle' action is to increase the engine speed to drive the transmission input gear speed), then swiftly press the clutch pedal again and shift the gear lever to the lower gear position. Poor coordination between the clutch and accelerator when starting the car can cause the engine to stall or the car to jerk during takeoff. The engine power is transmitted to the wheels via the clutch, with only a 1cm travel distance reflected on the clutch pedal. Therefore, after pressing the clutch pedal and engaging the gear, when lifting the clutch pedal to the point where the clutch friction plates begin to make contact, pause briefly at this position while simultaneously pressing the accelerator. Wait until the clutch plates are fully engaged before completely releasing the clutch pedal. This technique is called 'two fast, one slow'—the initial and final stages of lifting the pedal should be slightly faster, while the middle stage should be slower. During normal driving, do not rest your foot on the clutch pedal. Avoid using the clutch in a semi-engaged state while driving. If semi-engagement is necessary under special circumstances, minimize the duration to prevent burning out the clutch friction plates. The speed of releasing the clutch should not be too fast—generally slowest in first gear and slightly faster in other forward gears. When starting in first gear, the clutch pedal must be fully depressed. For subsequent upshifts, the clutch pedal only needs to be pressed enough to disengage the clutch friction plates before shifting, without requiring full depression.
