What role does Hill Assist on the car do

Hill Assist is designed so that when the car is parked on a steep slope when the car is started, the car will not slip backwards when the brakes are released.

Hill Assist (Hill-Start

assist

Control, HAC), is a function derived from the ESP system, which allows the vehicle to start on the slope without using the handbrake without slipping, and the driver's right foot leaves the brake pedal The vehicle can still continue to brake for a few seconds, so that the driver can easily turn the foot from the brake pedal to the accelerator pedal, avoiding the trouble of using the parking brake to get up the hill and make the driver feel busy.

control。When the vehicle is starting on a steep or slippery slope, the vehicle will slide backwards when the driver switches from the brake pedal to the accelerator pedal, making it difficult to start. To prevent this from happening, Hill Start Assist temporarily (up to about 2 seconds) applies the brakes to all four wheels to prevent the vehicle from sliding.

When Hill Start Assist is not equipped, the driver must switch from the brake pedal to the accelerator pedal quickly and accurately. However, when equipped with Hill Start Assist, the driver can easily start and operate the pedals because Hill Start Assist prevents the vehicle from sliding backwards.

How to use the car hill assist.

First of all, the gear lever is not in P gear position (automatic transmission models) and do not press the accelerator pedal; At this time, the vehicle also needs to be stationary; The operator did not turn on the handbrake (foot brake or electronic brake). When these conditions are met, the driver takes their feet off the brake pedal and Hill Start Assist is activated.

How it works. When the vehicle is uphill, the moment the foot leaves the brake pedal and is stepping on the accelerator, the HAC system will automatically maintain the brake oil pressure for 2-3 seconds, at which time the vehicle will not slip back due to gravity and inertia. When you press the accelerator, the system will gradually reduce the braking force, and when the HAC control of the brakes is over, the vehicle will move steadily with you pressing the accelerator.

If you don't press the accelerator, the HAC's automatic brake control will also end after 2-3 seconds, so you can press the accelerator without hastiness.

When Hill Start Assist is not equipped, the driver must switch from the brake pedal to the accelerator pedal quickly and accurately. However, when equipped with Hill Start Assist, the driver can easily start and operate the pedals because Hill Start Assist prevents the vehicle from sliding backwards.

It won't roll backwards when starting on a half-hill, which is a good configuration.

Hill Start Assist allows the vehicle to leave the brake pedal for a few seconds without the right foot of the brake pedal, allowing the driver to easily shift their foot from the brake pedal to the accelerator pedal to prevent accidents caused by rolling, and without the driver feeling overwhelmed.

Hill Assist is a very handy hill climb feature that is very friendly to novice drivers. When the Rubber starts on a slope and the driver shifts from the brake pedal to the throttle, the Hill Start Assist function prevents the vehicle from skidding backwards and prevents the vehicle from starting hard.

Today we're going to take a look at how to turn on Hill Assist.

The way to turn on Hill Assist is to turn on the ESP button. As long as ESP is enabled, Hill Assist is enabled by default.

Usually, the manual shift operation process for a hill start is to press the clutch pedal and brake pedal at the same time as the first step. In the second step, hook the clutch to first gear and slowly lift the clutch until the car shakes. Step 3, when you feel the car shaking significantly, slowly lift the brake pedal.

At this point, the car can start smoothly.

Many novice drivers, due to nervousness or unskilled operation, may lift the clutch too fast, or put the brakes too fast, or because of road conditions and other reasons, unable to start smoothly.

This is where the benefits of Uphill Assist can help. Hill Assist will allow the driver to apply the brakes to all four wheels within 1 2 seconds after releasing the brakes, so that the car does not slip down and backwards, giving the driver enough time to step on the accelerator. With enough throttle, the car will successfully climb hills.

Let's take a look at the opening conditions of the uphill assist function in the beam cover grip:

1.When the handbrake is not pulled, the gear lever of the manual transmission model should be in neutral.

2.The shift lever of an automatic transmission model should be in a non-P position.

3.The car is parked.

4.When you don't step on the accelerator.

The above are the conditions for the opening of the hill assist.
