What is the difference between Auto Hold and Hill Start Assist?

[BrooklynLynn]

Auto Hold and Hill Start Assist are two different functions. Although both are derived from the ESP system in terms of implementation principles, their usage scenarios differ. Here are the specific details: 1. The Hill Start Assist System is a function developed based on the ESP system. It allows the vehicle to maintain braking for a few seconds when starting on a slope without using the handbrake, even after the driver's right foot leaves the brake pedal. This enables the driver to easily transition their foot from the brake pedal to the accelerator pedal, preventing rollback accidents and avoiding any sense of panic. 2. The Auto Hold function uses a slope sensor to provide precise parking force through the controller. During startup, the parking control unit calculates information from sensors such as the clutch distance sensor, clutch engagement speed sensor, and accelerator pedal sensor. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly.
