Abstract:In my research This Will Provide the Acceleration SlipRegulation. On electric cars with an independent front-wheel drive.What is the regulation of acceleration slip (ASR)? If the vehicle isgoing on slippery roads and the engine gives more power thannecessary, the regulation of the acceleration slip controls thetorque or prevents the over rotation that leads to sliding of thevehicle, which is similar to the ABS system, as the ABS systemequals the speed of the wheels in case of slipping or in high speedturns which is control the traction [1]. And the process of slidingstrategy simulations using the MATLAB[2].Keyword: acceleration slip regulation, yaw rate.pg.2

1.0 Introduction:Why were electric cars made in first place? Electric cars helped todevelop technically and environmentally in terms of environmentalconservation, and were a good embrace of the economy. It is agood technical transition in the automotive world[2]. To achievesafety when driving, especially for sports vehicles that can go atgreat speed, the vehicles have been equipped with an accelerationslip strategy. It depends on controlling the yaw rate and takingadvantage of the grip of the road.What's the yaw rate? It is a sensor that can measure the angularvelocity of the vehicles in rad/s or degrees/s to determine thedirection of the vehicle's slippage in hard turns[3].(Figure.1) formula of front and rear sides [4].There are other methods other than relying on the speed of the carsuch as the speed and acceleration applied to the wheel. Theacceleration slip system works by data sent from the yaw sensorresponsible for calculating the angular degree of the tilt of thewheels, when the vehicle glides the system takes the speed of thelarger wheel and inserts it as a reference wheel and then reducesthe speed of the other wheel and this process is done by the yawmeter as it controls the rate of slippage.The Yao equipment determines the amount of tilt of the vehicleusing the gyroscope to determine the angle of the slip in otherwords calculating the difference between the direction of thevehicle and the actual direction of movement and then sending it inthe form of data to equal the speed of the wheels and apply theappropriate amount of braking power automatically.Corrective actions may include reducing engine power as well asapplying brakes to one or more wheels to reorganize thevehicle[7].pg.4
