Hill Start Assist or HSA is one of the safety systems in a car. Driving on an uphill road on a busy road is certainly very dangerous. The risk of the car rolling back or sliding is one of the bad things that could happen. Especially for novice drivers, this will be dangerous. That’s why there are now various safety features available in cars. One of them is the HSA feature. So how does it work? Check out the full review.
Understanding the Hill Start Assist Feature
HSA is one of the active safety features in vehicles. Specially designed to prevent the car from sliding when stopping on an incline. As is known, facing an incline while driving is not easy. Even a challenge for novice drivers. Passing through steep and uphill terrain is quite scary.
That’s why the HSA feature is present, known as Hill Assist Control, which makes the driver calmer. Because with this active safety feature, the car will be locked and will not move back when the brake pedal is released. This will give the driver time to press the gas pedal and move forward. HSA also helps ensure smooth acceleration when the car is climbing.
The risk of wheel slippage will be reduced. Because this feature will keep the car stable even when on an incline. This safety feature helps drivers drive much safer and more comfortably on uphill roads.
How HSA Works
Hill Start Assist has a fairly important role. The way this safety feature works on cars helps prevent vehicles from sliding on uphill roads. So that the driver will remain focused by moving their foot from the brake pedal to the gas pedal.
HSA works using two sensors that can detect the environment around the car, whether on an incline or a decline. The first sensor is able to read the uphill conditions of the car when in front of the car is indicated as high from the rear. While the second sensor works to read the speed of wheel rotation. So the two sensors have different roles.
The sensor will provide information to the braking system to automatically release the brakes with the gas pressure given by the driver. This working system will maintain brake pressure for a certain period. For example, when the driver’s foot moves from the brake pedal to the gas. After the gas pedal is pressed, the HSA feature automatically releases the brakes to help the vehicle climb the incline to the maximum.
As reported in the Sabin Civil Engineering YouTube video when the car is on an uphill road and wants to move to switch from the brake pedal to the gas in just a few seconds, gravity will work, namely bringing the car backwards. But now there is a new technology, namely Hill Start Assist, which can hold the brakes for a few seconds after the driver releases the brake to switch to the gas pedal. It can be said that HSA keeps the brakes active when on an incline.
Performing Regular Service to Maintain Hill Start Assist Performance
The HSA feature on the car can also work optimally when the vehicle is serviced periodically. Currently, almost all automotive companies present the HSA feature on their products. This feature is to prevent the car from moving backward when on an incline. To get the feature to work optimally, do routine maintenance.
Performing routine service helps technicians ensure that the safety features on the vehicle can work optimally, including the HSA feature. Where the Hill Start Assist feature can be disrupted if its condition is never maintained./sinta
