At what RPM on the slope can the brake be released?
2 Answers
You can release the brake when the tachometer reaches 8 during a hill start. Methods for hill starting: Automatic transmission models: Automatic transmission models require control during uphill positioning training. When starting the car, release the handbrake, press the brake pedal with your right foot, and then start. Shift the gear to position 1 or 2. Pay attention to gear changes when starting an automatic transmission model to avoid damaging the automatic transmission. Manual transmission models: When starting on a slope, gently lift the clutch pedal. When the car body starts to shake or gear engagement is felt, completely release the brake pedal and gently press the accelerator pedal to move forward.
I've been driving for over a decade, and hill starts are really all about feel - the tachometer is just an auxiliary reference at most. For manual transmissions, when you can feel the car slightly vibrating in the semi-clutch state while the tachometer stabilizes around 1000 rpm, that's the perfect moment to release the brake. Then gently press the accelerator to about 1500 rpm, and the car will climb steadily. It's even simpler with automatics - the transmission has a creep function, so just release the brake at 700 rpm idle speed. Only on particularly steep slopes do you need to give it some gas beforehand. The key is to practice more to find the rhythm of clutch engagement. Staring at the dashboard too much can actually make you fumble, since every car's clutch play and power response are different.
