CRUISE CONTROL Presentation Transcript:
1. Predictive Cruise Control: Utilizing Upcoming Traffic Signal Information for Improving Fuel Economy and Reducing Trip Time
2.NEED OF CRUISE CONTROL
A big portion of our time is spent behind traffic lights.
Fuel Consumption during this time is very high.
Lack of information about future state of traffic signal increases trip time & engine wear & tear.
Increases the CO2 emission.
3.CRUISE CONTROL
Utilizes the adaptive cruise control function in a predictive manner.
Improve fuel economy and reduce signal wait time.
The predictive speed control mode maintains a safe gap between vehicles.
4.Decreases use of brakes, thus reducing brake wear and kinetic energy loss.
Is applicable in stop and go traffic.
Receives a timing signal from an upcoming traffic light in advance to safely and smoothly speed up or down to a timely arrival at green light whenever possible, therefore reducing idling at red.
5.CO-OPERATIVE INFRASTRUCTURE
6.CVIS enables flexible, harmonized and open communication between vehicles, roadside equipment and management centers to improve existing services.
TLC create Green Window according to Priority of vehicle.
Loop detector on road is used to detect the vehicle and transponder is used to transmit the information to TLC.
7.MODEL PREDICTIVE CONTROL
The objective is to find the optimal vehicle velocity that reduces idling at red lights giving the future state of traffic lights.
8.REFERENCE VELOCITY PLANNING
9.OPTIMAL TRACKING OF REFERENCE VELOCITY
A simple model of the vehicle is used at the supervisory level for calculating the vehicle acceleration based on effective traction force of the engine fengine or fbraking braking force and the road forces .
10.Evaluation of Fuel Savings Potential With a Detailed Power train Model
