Operation of the ramp start assistance system

Página 27

The ramp-start assist system is a technology present in many modern automobiles. It helps the driver pull away on a steep hill without the vehicle rolling backwards.

The operation of this system is very simple. When the driver is on a ramp and takes his foot off the brake to accelerate, the system detects the slope and automatically applies the brakes for a few seconds. This prevents the car from rolling backwards as the driver accelerates.

To better understand how this works, you need to know a little about the car's braking system. Brakes are made up of a disc or drum that is driven by pads or shoes. When the driver steps on the brake pedal, the pads or shoes press against the disc or drum, creating friction and bringing the car to a stop.

In the case of the ramp start assist system, the system uses a technology called "hold". This technology keeps the brakes on for a few seconds after the driver takes their foot off the brake pedal. This prevents the car from rolling backwards as the driver accelerates.

The ramp start assist system is especially useful in heavy traffic situations where the driver may be stuck on a ramp for an extended period of time. It is also useful for novice drivers or those who drive cars with less powerful engines.

In summary, the ramp start assist system is a simple but very useful technology for drivers who need to start off on steep grades. It uses the car's braking system to hold the vehicle stationary for a few seconds after the driver takes their foot off the brake pedal, preventing the car from rolling backwards as the driver accelerates.
