What is the function of downhill assist in cars?

[Jace]

The function of downhill assist is to reduce the burden on the driver. The downhill assist control system can automatically maintain the vehicle speed at an appropriate level. Here are detailed explanations about downhill assist: 1. When using the downhill assist system, four-wheel drive must be activated. For short slopes, use the brakes; for long slopes, it is recommended to manually shift to a lower gear. The downhill assist system can be used on unpaved roads. 2. The main purpose of downhill assist is to prevent excessive speed when descending steep slopes, as it automatically matches engine braking for safer operation. 3. The DAC (Downhill Assist Control) system operates on the same principle as engine braking. The DAC system enables the vehicle to maintain a constant low speed, preventing wheel lock-up while significantly reducing vibrations when descending on rough roads, thereby ensuring driving stability and improving ride comfort.
