Why Does the Car Stall on a Slope?
2 Answers
Failure to promptly apply the throttle. Below is a partial introduction regarding starting on a slope: 1. Rules: Timing for starting on a slope begins from the moment of starting. When driving, decisively pull the handbrake and press the foot brake, then release the clutch to feel the vibration, and release the brake. The starting process must not exceed 30 seconds. Exceeding 30 seconds results in a deduction of 100 points. 2. Precautions: After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line, and the deviation exceeds 50 centimeters, it is considered a failure; if the deviation does not exceed 50 centimeters, a deduction of 20 points is applied.
I've experienced stalling on an uphill before, and the main issues lie in throttle-clutch coordination and power delivery. When starting on a slope, releasing the clutch too quickly without matching throttle input causes the engine to lug and stall instantly. While automatic transmission cars rarely stall, releasing the hill-start assist too abruptly can also cause jerking or stalling. I remember once driving a manual transmission car fully loaded up a parking garage ramp—the engine started shuddering as soon as I lifted the clutch, and I had to floor the throttle to recover. The key technique is to gradually release the clutch to the friction point while holding the brake, then when you feel slight vehicle vibration, quickly switch your right foot to the throttle for power while continuing to slowly release the clutch. This prevents both rollback and stalling—practice a few times to develop muscle memory.
