Driveline Vibration Reduction of FR(front engine rear wheel drive) Vehicle at Rapid Acceleration

Integrated control of active rear differential and front wheel steering in rear wheel drive vehicles

Many vehicle control systems were designed and implemented in the last years to enhance performances and stability acting on front and/or rear steering actuators [1,2,3] and/or individual wheel braking [8]; the development of electroactuated differentials allows to transfer torque between wheels from the faster to the slower one in semiactive differentials [11,12,13,14] and in both directions i...

Wheel Speed Control Algorithm for Rear Wheel Motor Driven Vehicle

The conventional vehicles in the past had consisted of mechanical differential which converts the engine torque in to two directions. Due to the introduction of electric vehicle the vehicle propulsion system has changed from combustion engine to electric motor. Since the concept of differential is a must have component to drive a vehicle, it is still used in electric vehicles as well. Common me...

Optimizing Vehicle NVH Characteristics for Driveline Integration

The automotive marketplace has seen a steady increase in customer demands for quiet and more comfortable vehicles. A customer’s expectations for NVH refinement often contradicts the constraints for lightweight vehicle designs and the need for a powertrain with increased fuel efficiency. The driveline of a vehicle can be a substantial cause of NVH issues. Variants in the driveline architecture (...

Robust Shared-Control for Rear-Wheel Drive Cars

Nowadays vehicles are one of the major means of transportation. The driving safety depends highly on the driver’s attention, experience and skills. According to the report given by the World Health Organization, more than one million fatalities are caused by traffic-related accidents per year all over the world. To keep the human beings out of the vehicle control loop and to relieve them from t...
