An antilock braking system (ABS) is one of the most important components in a road vehicle, which provides active protection during braking, to prevent wheels from locking-up and achieve handling stability steerability. The all-electric ABS without any hydraulic potential candidate for electric vehicles. To demonstrate examine algorithms, this article proposes single-wheel test bench, mainly in...

The year is 1967. The cars are monstrously powerful, extremely light, and the tires are so hard that a single set will often last three race weekends! Brakes are terrible. Forty gallons of volatile gasoline surround the driver— contained by nothing more than a thin skin of fragile aluminium—and there are no seatbelts. The circuits are breathtakingly beautiful, supremely challenging, and brutall...

Injuries unique to pregnant occupants involved in motor-vehicle crashes include placental abruption, uterine rupture or laceration, and direct fetal injury. The mechanisms and characteristics of these injuries are discussed using examples from a literature review and from recent investigations of crashes involving pregnant occupants. In addition, a review of the relationship between the pregnan...

An Two wheel self supporting robot is design using IOC(Internet-on-a-chip) controller. The DC motor is controlled by PWM technique. In the existing system the robot were designed using tilt sensor, IR sensor, Attitude sensor and moving robot in a straight line. We propose a new design in two wheel self support robot using the principle of curvature technique, were a force that makes the robot t...

Typical obstacle-recognition systems on mobile robots use stereo-vision or laser ranging to perform classification. The Yeti Robot, a robot designed to perform medium range autonomous traverses in Antarctica and Greenland, is not currently equipped with vision or LADAR, but has a proprioceptive sensor suite including 6-axis IMU, wheel encoders, wheel motor current, and GPS. The purpose of this ...

In this paper we present the design of a car test bed. The main characteristic of our test bed is the steering which is Non-Holonomic to resemble the normal car steering. This test bed is a rear wheel drive with frontal steering by servo motor. The control brain consists of RoBoard II and Arduino Micro controller. We used multiple sensors (Ultrasonic range finder, 6 DOF Accelerometer, Wheel enc...

A method for obtaining error-tolerant cyclic sequences similar to de Bruijn sequences is presented. These sequences have a number of potential applications, including use as absolute rotary encoders. This investigation is motivated by the desire to use a vision-based system to obtain the angular position of the wheels of mobile robots as they rotate about their axes. One benefit of this approac...

This paper describes an odometric system for autonomous microrobots based on the optical properties of a motor–wheel transmission for motion feedback. We demonstrate that infra-red light, reflected from this mechanical system, shows distinctive periodic changes of amplitude, correlated with the motion of the robot. Real-time odometric signal processing, performed on a small embedded microcontro...

In this paper, a torque distribution control for electric vehicles with an in-wheel motor installed each wheel is proposed in order to manage the traction operation of vehicle and avoid slip ratio from reach extreme values while moves into slippery surfaces. The driving force main controller system its consist two loop. PD-Fuzzy logic PI-control are applied as speed inner loop aim improving sta...

Recently, there has been significant attention given to the electrification of transportation due concerns about fossil fuel depletion and environmental pollution. Conventional drive systems typically include a clutch, reduction gear, mechanical differential, which results in power loss, noise, vibration, additional maintenance. However, in-wheel motor technology eliminates need for these compo...
