Will a manual transmission car with hill-start assist roll back?
1 Answers
Manual transmission cars with hill-start assist can still roll back. Function of hill-start assist: Hill-start assist, also known as Hill-start Assist Control. When starting on a steep or slippery slope, if the driver switches from the brake pedal to the accelerator pedal, the vehicle may roll backward, making it difficult to start. To prevent this, the hill-start assist control temporarily applies braking force to all four wheels to prevent the vehicle from rolling back. When equipped with hill-start assist control, since it prevents the vehicle from rolling backward, the driver can start the car more easily and operate the pedals more comfortably. Conditions for automatic activation of hill-start assist: The vehicle must be on an uphill slope, not in P gear, not pressing the accelerator, the car must be stationary, and the handbrake must not be engaged. This function mainly assists the vehicle when going uphill. If the vehicle encounters an uphill section, the hill-start assist will help the vehicle climb, facilitating smoother driving, as if automatically hiring a pusher to save effort. When encountering an uphill slope, with auto-hold activated, the vehicle will not roll back, and unlike hill-start assist, there is no time limit—it will continue to provide braking force as long as the accelerator is not pressed.
