Convenience features of Venga (Part 1) February 10th, 2010
The name Venga is derived from Spanish for ‘Let’s go’ or ‘Come’ and has a playful connotation like a cartoon character. The for-Europe-only Venga is styled according to the Kia family look and features a wide range of cutting-edge convenience items. We’ll take a look at all of the convenience features and new electronic technologies in a series of three postings. So come on, let’s go, go, Venga!
HAC (Hill-start Assist Control)
Chassis Design Team 1
When a car stops on a hill and then starts again, it tends to draw back a little. This phenomenon can even cause some drivers to get sweaty palms when the car stops on a very steep incline.
For an inexperienced driver, it takes more time to move their foot from the brake to the gas pedal, increasing the risk of the car moving backwards and causing a potentially dangerous situation.
The Venga’s Hill-start Assist Control (HAC) will free drivers from such risks and worries.
HAC maintains braking pressure for a certain amount of time while the driver moves their foot from the brake to the accelerator pedal. Along with Electronic Stability Control (ESC), the technology prevents the car from moving backwards and allows for a safer driving experience.
In vehicles without HAC, when the driver engages the brake by depressing the brake pedal and then removes their foot, the braking pressure that maintains the braking state is lessened. However, as seen in picture below, vehicles with HAC maintain braking pressure even when the driver’s foot has moved off the brake pedal until the driver pushes on the accelerator.
HAC operates with the ESP (Electronic Stability Program) on/off switch which actively controls the engine torque and braking in circumstances when it is difficult for drivers to control the vehicle, during sudden stops and turns, for example. By designing HAC to become activated when ESP is ‘on’, the driver can control the vehicle’s movement with greater safety.
The next posting in this series will introduce the Venga’s Discharge temperature controlling A/C system. Stay tuned!
