anti-lock braking system, or ABS is a safety system which prevents the wheels on a motor vehicle from locking up (or ceasing to rotate) while braking.A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to continue interacting tractively with the road surface as directed by driver steering inputs. While ABS offers improved vehicle control, and may decrease stopping distances on dry and especially slippery surfaces, it can also increase braking distance on loose sur ....etc

Abstract:
Anti-lock braking systems (ABS) take a lot of the challenge out of this sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can't stop as quickly without ABS as an average driver can with ABS.anti-lock braking system, or ABS is a safety system which prevents the wheels on a motor vehicle from locking up (or ceasing to rotate) while braking.A rotating road wheel allows the driver to maintain steering control under heavy braking by preventing a skid and allowing the wheel to cont ....etc

SKID RESISTANCE ON PAVEMENTS


INTRODUCTION
Road engineers & users are concerned with the safe passage of vehicles that operate over them.
Safety on road is assessed by its skid resistance.
Slippery pavements are known to be the cause of many road accidents and fatalities.
Skid resistance involves the complex interaction of pavement , vehicle and environment factors.


SKID RESISTANCE
Skidding is the jerking of the wheels of the vehicles when it locked due to the sudden breaking , if the frictional ....etc

Most wheeled mobile robot (WMR) controllers have been developed based on nonskidding and nonslipping assumptions. Unfortunately, wheel skidding and slipping are inevitable due to wheel tire-deformation; consequently, the stability and performance of these controllers are not guaranteed. This brief aims to develop a global positioning system (GPS)-based path following a controller for a car-like wheeled mobile robot in the presence of wheel skidding and slipping. The proposed control scheme uses real-time kinematic (RTK)-GPS and other aiding sen ....etc

Abstract-- A car that controls its self is a marvel. Naturally, one of the best ways to control the car is with a control system. The car is driven by differential steering meaning that there is a motor on each of the two driving wheels. The first step to analyze what the system needs to control the car; research was done on sensors, cameras, and power systems. Then research was done to determine how various sensors, cameras, and motor controllers worked and which combination would work best for the requirements of the ....etc

Abstract:
ABS system includes wheel-speed sensors, a hydraulic control unit, and an electronic control unit. When apply the brake pedal, the electronic control unit monitors and compares the signals from the wheel-speed sensors. If the electronic control unit senses rapid deceleration (impending lock-up) at a given wheel, the electronic control unit commands the hydraulic control unit to reduce hydraulic pressure to that wheel. ABS system preventing a skid and allowing the wheel to continue interacting tractively with the road surface as dire ....etc

VEHICLE SKID CONTROL
1. INTRODUCTION
Vehicle skid can be defined as the loss of traction between a vehicleâ„¢s tyres and the road surface due to the forces acting on the vehicle. Most skids are caused by driver error, although only about 15% of accidents are the direct result of a vehicle skidding. Skids occurring in other accidents are usually the result of last minute action, by the driver, when faced with a crisis ahead rather than actually causing an accident. Skids can occur both in the dry and wet as well as ....etc

ABSTRACT
Anti-Lock Braking Systems (ABS) are designed to maintain driver control and stability of the car during emergency braking. Locked wheels will slow a car down but will not provide steering ability. ABS allows maximum braking to be applied while retaining the ability to 'steer out of trouble'
The theory behind anti-lock brakes is simple. A skidding wheel (where the tire contact patch is sliding relative to the road) has less traction than a non-skidding wheel. By keeping the ....etc

AN INVESTIGATION OF ANTI-LOCK BRAKING SYSTEMS FOR HEAVY GOODS VEHICLES

ABSTRACT
An articulated lorry was instrumented in order to measure its performance in straight-line
braking. The trailer was fitted with two interchangeable tandem axle sub–chassis, one with
an air suspension and the other with a steel monoleaf 4–spring suspension. The brakes were
only applied to the trailer axles, which were fitted with anti–lock braking systems (ABS),
with the brake torque controlled in response to anticpated locking of the lea ....etc
