The presence of an incline is detected by sensors inside the car. As you transition from the brakes to the gas pedal, the hill start assist maintains the brake pressure for a predetermined amount of time. The brake is released as soon as the accelerator is pressed. When a car with a manual transmission has this feature, the hill start assist will additionally keep the brakes applied until the clutch is released.

Hyundai Accent: Control for hill-start assistance (HAC)
A hill starts Assist Control is a useful feature. The primary goal is to prevent
the vehicle when starting uphill from a halt and preventing it from sliding backwards. HAC is held
The driver has adequate time to depress the accelerator during the pressure-hold phase.
As soon as the system recognizes the driver’s intention, the brake pressure is decreased.
if the car cannot be held by hold pressure alone, the driver must immediately engage
stomping on the brake pedal to stop the car from rolling backward. unanticipated rolling
- When the transaxle shift lever is in the P position, the HAC is not activated (Park)
- Even when the ESP is off, the HAC nevertheless activates but the ESP does not.
The stability and steering reactions of the vehicle are further improved by this system.
You can set the cruise control system to keep the car traveling at a set speed.
Recent upgrades to the Hyundai Venue include the clutchless manual transmission (iMT) gearbox. Here is a demonstration of the hill hold control that is included.
Whether the Hyundai Venue will roll backwards on an uphill slope is one of the frequently asked questions by customers about the Hyundai Venue and its iMT transmission. To stop a manual car from going backwards, you must either apply more force to the clutch or increase your rate of acceleration. However, how can the iMT gearbox function without a clutch?
The Hyundai Venue iMT is tested on an uphill and a downhill in the following video. The motorist releases the brake pedal after shifting into first gear but does not use the accelerator. The vehicle moves a few steps backward before automatically starting to go forward again. There is the hill assist control in action.
To test the Venue’s hill descent control, the owner then tries to reverse the vehicle down a hill. Even at this point, the automobile begins to reverse again as soon as he lifts his foot off the brake pedal and drives forward a few feet. In both of these scenarios, an automobile can only travel at a maximum speed of 7 to 10 km/hr.
As you can see, the Hyundai Venue iMT does include descent control and hill assist. Actually, it is a useful tool for individuals who are students. They don’t need to worry that the car would reverse on a slope and hit another vehicles. In contrast to many manual cars, all automatic and semi-automatic vehicles typically have this feature.
The owner also makes an effort to contrast the iMT with AMT. Both of them have the same mechanism for the hill assist control. They run very differently, though. Automated Manual Transmission, or AMT, is essentially a quick way to turn a manual gear into an automatic. As a result, the gear shifts jerk just as in a manual, but the fuel efficiency is higher.
What’s the process of a Hill Start Assist?
When making a steep start, Hill Start Assist briefly prevents you from rolling forward or backward. By keeping pressure on the braking system for an additional 2.5 seconds, the system gives you more time and control as you shift your foot from the brake pedal to the accelerator.
What parts are used in Hill Start Assist?
The electronic control unit (ECU), a brake actuator that is under its direction, and a variety of different sensors are all components of the hill-start control system. The specific sensors included may vary depending on the implementation. We’ll examine each of these safety and regulating devices separately; keep in mind that certain hill-start control systems do not necessarily need all of the components listed below:
The angle of the car on an incline, which corresponds to the slope of the hill the car is on, is detected by angle sensors.
Pressure sensors: These are a component of the vehicle’s suspension system and are capable of detecting the weight of the entire vehicle, including both passengers and luggage. Strain gauges or piezoelectric sensors can also accomplish this. These sensors generate an electrical signal whose amplitude is proportional to the vehicle’s weight.
Torque is the engine’s rotating force, which finally causes the vehicle to accelerate from a full stop. The drivetrain’s ability to transmit torque to the wheels can be measured by the torque sensor.
Wheel-speed sensors: These devices, which are typically mounted on the axles, may measure the speed and rotational direction of the wheels.
The embedded computer system in the car, known as the electronic control unit (ECU), is what receives data from the numerous sensors. Based on such input, the ECU determines when the brakes must be applied. The weight of the vehicle (as determined by the pressure sensors) and the incline of the hill it is moving up can both be taken into account by the ECU to compute the traveling resistance (determined by the angle sensors). To determine how much engine torque will be required to propel the car uphill, traveling resistance is used.
Actuator for the brakes: An actuator is a machine that transforms an electrical signal into a physical motion. The ECU sends a signal to the brake actuator instructing it to apply the brakes. The vehicle is then held in place by the brakes, which prevent it from rolling back down the slope, when the brake valves have been opened. A hybrid car’s electric motor can be utilized in place of the brake to impart enough forward motion to prevent the car from sliding backward.
The torque sensors assist the ECU in determining if the engine’s torque is sufficient to overcome the moving resistance once the driver begins to accelerate (already calculated by the ECU). If so, the ECU instructs the brake actuator to release the brakes and permit the vehicle to move.
The driver ought to be completely unaware of all of this. The driver should not be aware that braking force was still being applied after the brakes have been released since the brake release should be extremely smooth. The driver won’t know until much later that he or she never once had to be concerned that the automobile would slide back down the hill and hit the car behind it. Rarely is driving safety this simple.
Is the added cost to purchase a car with hill-start control worth the added sense of security it provides? That query will be addressed on the following page.

What Hyundai model offers hill assist?
Hyundai Venue models including the S 1.0 AT Petrol, S 1.0 Turbo DCT, S (O) 1.0 Turbo DCT, and SX 1.0 all come with the hill assist technology (O) SX 1.4 (O) CRDi, SX 1.0, and petrol (O) Turbo Dual Tone, 1.0 AT SX Plus Petrol, SX (O) 1.5 CRDi Executive, SX (O) 1.0 Turbo, and SX (O) 1.5
What is the hill start assist manual used for?
Press the brake pedal to bring the car to a complete stop before using the HLA in manual mode. Hold the brake pedal down. As soon as you hear a chime and see Hill Launch Assist enabled in the information display, quickly press the brake pedal a little bit more.
Do you need a hill start assist?
Few drivers actually need this feature, but because it lowers the chance of an accident, it makes hill starts safer.
Inevitably, more new cars will be equipped with hill-start assist due to the relatively low cost of the technology.
Models with electronic parking brakes make it so that all the driver needs to do to start driving down a hill is locate the clutch’s bite point and start moving. At the same moment, the brake and hill start assist immediately disengage.
Some cars include an additional Auto Hold system for the brakes; VW Group vehicles in particular have a particularly good system. When the driver comes to a stop, they only need to lightly press down on the brake pedal to engage the hill-start assist and electronic parking brake, respectively.
Does hill assist operate on its own?
When you press and release the brakes on a slope, a technology called “Hill Start Assist” immediately engages to prevent your car from rolling back while holding the brake pressure.
Does the reverse hill start assist function?
When you press and release the brakes on a slope, a technology called “Hill Start Assist” immediately engages to prevent your car from rolling back while holding the brake pressure.
The Hill Start Assist feature automatically maintains the pressure in the braking system when you let off of the brake pedal for a brief period of time to prevent your car from rolling back unintentionally. The brakes will then release when you press the accelerator. When using this feature to navigate both uphill and downhill roads, the driver is protected. However, if the car detects an uphill while in “reverse” or a downhill while in “drive,” Hill Start Assist won’t engage.
My hill start assist light is on—why is that?
WARNING Have the car inspected at a licensed Subaru dealer when the Hill Start Assist Warning Light comes on. The Hill Start Assist OFF indication light glows constantly while the Hill Start Assist system is disengaged to let the driver know it is not in use.
Do all modern automobiles have hill assist?
A form of auto technology called hill start assist helps you move the car forward safely when it is inclining. Many new automobiles are equipped with it, and many secondhand models from the last ten years or so also include the technology.
It is not a particularly innovative piece of technology. It essentially holds the car’s brakes on for you when you move your right foot from the brake to the accelerator, allowing you to relax and avoid rushing up hills or fiddling with the handbrake.
When your car is on a slope, a sensor detects it. Typically, the system only works when the car is facing up the incline, but some vehicles can also use the system when the car is looking down.
You don’t need to do anything because it will operate on its own. The automobile won’t roll back if you simply raise your foot off the brake. When the road is level, you can start to lift the clutch and depress the accelerator. It replaces the traditional method of holding the car on the handbrake while you pull away and is especially helpful in vehicles without a manual handbrake.
On a vehicle with an automatic transmission, the function only keeps the vehicle from rolling back as you press the pedal. The auto releases the brake when you begin to go forward. For individuals who live in a mountainous area, hill start assist is a very practical and easy-to-use piece of technology that is available on all types of cars.
However, if you aren’t moving forward, don’t rely on hill-start assist to keep the car still on an incline. It won’t necessarily keep the car stationary forever, so use the handbrake if you need to stop for longer than a few seconds. Some versions release the brake after a short period to allow you to roll the car back. As you move away, many vehicles equipped with an electric handbrake system will also automatically release it.
