Another one in our explainer series – we tell you about the functions of Hill Assist Control to you. We explain the concepts and show you the working as well.

Let us learn how Hill Assist Control works.

Hill-Assist is a mechanism in vehicles that holds the brake until the clutch reaches its friction point, making it easier to drive uphill from a standstill. This mechanism works in both manual and automatic gearboxes.

This driver assistance system is also called Hill-Hold Control or Hill Start Assist.

To simplify the mechanism, this function works using two sensors. The first sensor measures the degree of incline of the vehicle and the second sensor is used for disengaging the mechanism.  

In a manual transmission vehicle, once an incline is approached and the front end of the car is pointing higher than the rear end, the hill-assist control system engages as soon as the brakes are depressed. The system then disengages as soon as the clutch is fully depressed and the vehicle moves forward using the first gear.  

Similarly, in an automatic transmission, tilt-angle sensors are installed in vehicles that trigger the system as soon as a vehicle reaches a certain angle. Once engaged, the braking system holds the brake for a few seconds after releasing the brake pedal, leaving the driver with a window of a few seconds to press the accelerator and move forward.
