Due to complex and nonlinear dynamics of a braking process and complexity in the tire–road interaction, the control of automotive braking systems performance simultaneously with the wheel slip represents a challenging problem. The non-optimal wheel slip level during braking, causing inability to achieve the desired tire–road friction force strongly influences the braking distance. In addition, ...

In recent years, two-wheeled inverted pendulum vehicles realizing high mobility have been developed. In such vehicles, an inverted pendulum control system maintains the vehicle’s stability by only using the two driving parallel wheels. Therefore, the gravity center of the vehicle body with a passenger is higher than the wheel axis, and the vehicle is moved by leaning the vehicle body forward or...

The series Hybrid-Electric Drive (HED) architecture brings a significant range of potential benefits to military ground platforms. Electric-drive wheeled vehicles can feature electric traction motors in a conventional driveline, but also offer potential for motor incorporation into the axle or the wheel hub. The implementation of in-wheel hub drives presents challenges both in their design and ...

This paper presents an experimental study of the electronic differential system with four-wheel, dual-rear in wheel motor independently driven an electric vehicle. It is worth bearing in mind that the electronic differential is a new technology used in electric vehicle technology and provides better balancing in curved paths. In addition, it is more lightweight than the mechanical differential ...

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...

nonlinear hunting speeds of railway vehicles running on a tangent track are analytically obtained using hopf bifurcation theory in this paper. the railway vehicle model consists of nonlinear primary yaw dampers, nonlinear flange contact stiffness as well as the clearance between the wheel flange and rail tread. linear and nonlinear critical speeds are obtained using bogoliubov method. a compreh...

Antilock braking system (ABS) stops a vehicle wheel without locking while decreasing the stopping distance. Here we use fuzzy logic to detect the road conditions. Vehicle dynamics and braking systems is complex and proposed controller in different road detected states. They behave strongly non-linear which causes difficulties in developing a classical controller for ABS. Fuzzy logic, however fa...

A question of major importance in the auto industry concerns the modeling and improved design of vehicle tires. Tire performance affects the handling performance of the automobile. Many of the variables on which tire performance depends can be calculated from the load and deflection of the spindle in the suspension system for each wheel. The question of tire performance thus becomes a question ...

1,2,3 B.E. Scholar BVCOE&RI Nashik(India) ABSTARCT Antiknock braking systems are used in modern cars to prevent the wheels from locking after brakes are applied. The dynamics of the controller needed for antiknock braking system depends on various factors. The vehicle model often is in nonlinear form. Controller demand to provide a controlled torque necessary to maintain optimum value of the wh...

The distance between the driver and the steeringwheel airbag module at the time of deployment has been identified as an important factor affecting the frequency and severity of airbag-induced injuries. Pre-crash positioning may influence the clearance at the time of deployment. Data from in-vehicle studies of driving posture were analyzed to determine the clearance between the steering wheel an...
