Description:
CRUISE CONTROL MANAGEMENT SYSTEM

Technical Field

The present invention relates to a system which enables to control and manage a cruise control upon the driver applies pressure to the pressure sensor located on the steering wheel instead of the brake pedal while the cruise control in the vehicle is on.

Background of the Invention

Today, use of cruise control provides benefit for drivers in terms of both comfort and fuel consumption in vehicles travelling particularly on highways and divided multi-lane roads. The cruise control keeps the vehicle speed fixed at a predetermined speed value. Currently used cruise controls require driver intervention in cases where the vehicle changes lane in traffic or goes between other vehicles. The cruise control is deactivated when the driver brakes and it is activated by the user again upon request. If the driver has lifted up his/her feet to rest them, s/he has to put his/her foot on the brake pedal at first and then adjusts the speed of the vehicle by braking. Efficiency of use of cruise control decreases in heavy traffic areas and this reduces driving comfort in long distances. In today’s advanced cruise control applications, adaptive cruise control (ACC) systems which operate with a radar and camera duo added to the vehicle and enable to adjust the vehicle speed automatically in the event that the vehicle in front slows down, have been developed. However, installation of these systems require expensive devices such as radar and camera. In addition, ACC systems may be inadequate in case of sudden speed change needs although they enhance the driver comfort and they don’t enable speed change according to the driver’s comfort preference. Considering the studies in the state of the art, it is understood that that there is need for a system which enables to take action in relation to the driver’s decision about decelerating/accelerating the vehicle in cases where the cruise control is inadequate by means of pressure sensors placed onto the steering wheel.

The Chinese patent document no. CN201646713, an application in the state of the art, discloses a“cruise control” and a system for controlling this system. The system is connected with an analog/digital converter and controlled by SET/deceleration key and RES/acceleration keys that are pressure sensors. A vehicle can be accelerated and decelerated while cruising. The longer the key pressing time is, the larger the automobile speed change is and the larger the key pressing force is, the higher efficiency is observed. This system which is located in the electronic control unit placed inside the steering wheel, prevents mixing accelerator and brake pedals and stepping on them accidentally by panic.

Summary of the Invention

An objective of the present invention is to realize a system which enables to control and manage a cruise control upon the driver applies pressure to the pressure sensor located on the steering wheel instead of the brake pedal while the cruise control in the vehicle is on.

Another objective of the present invention is to realize a system which enables to reduce the reaction time in cases where it is required to brake suddenly while the cruise control in the vehicle is on.
