Abstract
The design research in this paper is a case study of application of regenerative braking system to the Dzire car and improvements in regenerative braking system for the fixed output generation for the particular position of the acceleration pedal. In the regenerative system, the output of the vehicle is combined with the motoring output of the pump/motor and the engine to supply an amount of fuel corresponding to the position of the acceleration pedal, to drive the wheels at the starting. The research question addressed in this paper is the solution to the disadvantage of the existing regenerating system. i.e., sum of the outputs of the engine and the motor cannot be fixed because the output of the motor is varied due to the variation of the inner pressure of the accumulator even when the acceleration pedal position is fixed.To address the above problem we proposed a modified hydraulic layout and we did a case study on Maruti Swift Dzire Diesel engine and proposed five solutions which are used to control the fixed output for the fixed position of the accelerator pedal. The solutions are optimized using the decision matrix and the results are satisfactory.
