How to prevent rolling back when starting on a slope with an automatic transmission?
1 Answers
Different types of parking brakes require different methods to prevent rolling back. Below are specific methods for preventing rolling back when starting on a slope with an automatic transmission for different brake types: 1. Mechanical handbrake models: If the handbrake is mechanical, first engage the handbrake firmly when parking on a slope, then release the brake pedal and press the accelerator. When the vehicle body starts to vibrate forward or moves slowly forward, release the handbrake. 2. Electronic handbrake models: The electronic handbrake is relatively more complicated. To release the electronic handbrake, you must first press the brake pedal, so you cannot press the accelerator first and then release the handbrake like with a mechanical handbrake. When starting on an uphill slope, press the brake with your left foot and the accelerator with your right foot. Release the brake pedal only when the vehicle's forward driving force is sufficient, somewhat similar to a launch start. Additionally, using the left foot to press the brake pedal on the right side can indeed feel awkward. 3. AUTO-HOLD: One of the main reasons for AUTO-HOLD is to prevent rolling back on slopes. When parking on a slope, turning on AUTO-HOLD will automatically engage the handbrake. When starting, simply press the accelerator, and the handbrake will automatically release when the vehicle detects the wheels rolling forward, thus preventing rolling back. However, it is not recommended to use it on flat roads because the electronic handbrake takes about 2 seconds to engage or disengage, which can be inconvenient in urban driving. Moreover, repeated braking puts a significant burden on the brake pump.
