Can Hill Start Assist Be Installed Aftermarket?

[LeNolan]

Automatic transmission vehicles can have hill start assist installed aftermarket, but whether it's possible depends on the specific model. The hill start assist system is a function derived from the ESP system, allowing the vehicle to start on an incline without using the handbrake and preventing it from rolling backward. The driver can release the brake pedal with their right foot, and the vehicle will maintain braking for a few seconds. The principle of hill start assist: When the vehicle is on an incline, the moment the driver moves their foot from the brake pedal to the accelerator, the hill start assist system automatically maintains brake fluid pressure for 2 to 3 seconds, preventing the vehicle from rolling back due to gravity and inertia. When the accelerator is pressed, the system gradually reduces braking force, and once the hill start assist's brake control ends, the vehicle moves forward smoothly with the accelerator. If the accelerator is not pressed, the automatic brake control of the hill start assist will also end after 2 to 3 seconds, allowing the driver to press the accelerator at a relaxed pace.
