INTRODUCTION

Super Handling-All Wheel Drive or SH-AWD is afull-time, fully automatic all-wheel drive tractionand handling system designed and engineered byHonda Motor Company.

SH-AWD as a system " that provides corneringperformance that responds faithfully to driverinput, and outstanding vehicle stability.

In a hard turn, of percentage of power distributedto the rear wheels, up to 100% of the rear wheel

power can be distributed to the single, outer rearwheel. This action will push the rear around thecorner, and helping with steering, reducingundersteer and keeping the car balanced and

controlled.

Yaw rate sensor

A yaw rate sensor is a gyroscopic device that

measures a vehicles angular velocity around itsvertical axis. The output is usually in degrees persecond or radians per second.Speed sensorA wheel speed sensor or vehicle speed sensor

(VSS) is a type of tachometer. It is a senderdevice used for reading the speed of avehicle's wheel rotation. It usually consists of atoothed ring and pickup.

Steering Angle sensor

The steering angle sensor is mounted on

the steering shaft.Lateral G-Force sensor or Accelerometer

An accelerometer is a device that

measures proper acceleration. This is notnecessarily the same as the coordinateacceleration (change of velocity of thedevice in space), but is rather the type of

acceleration associated with the

RACK AND PINION

A rack and pinion is a type oflinear actuatorthat comprises a pair ofgears which convert

rotational motion into linear motion. The circularpinionengages teeth on a linear "gear" barthe rack. Rotational motion applied to the pinion

will cause the rack to move to the side, up to thelimit of its travel.

Motors-In this we have replaced the axle or differentialarrangement which is used In actual cars bymounting motors on each wheel.All the motors used for wheels are 12v dc supply

150 r.p.m.Wheels-rubber tyres of diameter 7cm.the tyres are chosenso that they provide sufficient friction or grip toget requisite handling of the model. Their sizeprovide proper ground clearance to the model.

RF MODULE

The RF module, as the name suggests, operates atRadio Frequency. The corresponding frequency

range varies between 30 kHz & 300 GHz. In this RFsystem, the digital data is represented asvariations in the amplitude of carrier wave.

HT12DThis is decoder series of CMOS for remote control

application HT12D capable of decoding 12bit ofinformation which consist of 8 address bits and 4data bits.HT12D provide 4 latch type data pins

whose data remain unchanged until new datacomes.

INTEGRATIONS FOR THE SYSTEM

Anti-lock Braking System (ABS)An anti-lock braking system (ABS, from German:Antiblockiersystem) is a safety system that allows

the wheels on a motor vehicle to continueinteracting tractively with the road surface asdirected by driver steering inputs while braking,preventing the wheels from locking up (that is,ceasing rotation) and therefore avoiding skidding.

channel Vehicle Stability Assist (VSA)Sensors are placed around the vehicle to help

detect when a side slip is occurring. These sensorsinclude wheel speed sensors, steering anglesensor, yaw rate sensor and lateral accelerationsensor. The intelligent unit that detects andcontrols the VSA system to correct a side slip is

the VSA-ECU component. This component detectsundersteers or oversteers by comparing the targetyaw rate by the driver with the actual yaw rate ofthe vehicle.

Electronic Brake Force Distribution (EBD)

Electronic brakeforce distribution (EBD or EBFD),Electronic brakeforce limitation (EBL) is anautomobile brake technology that automaticallyvaries the amount of force applied to each of avehicle's brakes, based on road conditions, speed,

loading, etc. Always coupled with anti-lock brakingsystems, EBD can apply more or less brakingpressure to each wheel in order to maximizestopping power whilst maintaining vehicular

control.
