Thesis (Ph.D.) - University of Warwick, 1992.
The emphasis in this thesis is on the analysis of traction control systems. The analysis is performed on simulation models and is supported by implementations on the real vehicle. The level of modelling appropriate for the analysis is justified and models developed in a modular manner. The individual modules are developed on the basis of published material and previous work within Ford Motor Company. Based on the analysis, two traction control strategies Author: Paul Richard Crossley. Part of the Communications in Computer and Information Science book series (CCIS, volume ) Abstract A dynamic model of four-wheel-drive vehicle was established and the Traction Control System (TCS) algorithm based on fuzzy-PID control was realized through rectifying the output torque of engine in real time and then switching parameter of fuzzy-PID controller was Cited by: 5.

Analysis of Traction Control Systems Augmented by Limited Slip Differentials Traction Control Systems (TCS's) are becoming increasingly present in today's automobiles. These systems strive to improve the traction and stability characteristics of the vehicle by actively controlling wheel by: In order to perform studies under traction, the model contains a subroutine in Gensys with a simplified traction system based on the bogie traction control strategy of one inverter . The forces and moments/torque that influence vehicle motion along the longitudinal axis include those due to the power train (including, in selected models and traction control), the brakes, the aerodynamic drag, and the tire-rolling resistance, as well as the influence of gravity when the car is moving on a road with a nonzero inclination (or grade). In a traditional cruise control system. In turbocharged vehicles, a boost control solenoid is actuated to reduce boost and therefore engine power. Typically, traction control systems share the electrohydraulic brake actuator (which does not use the conventional master cylinder and servo) and .
Traction control helps limit tire slip in acceleration on slippery surfaces. In the past, drivers had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver. Modelling and Simulation of Electrical Drive using SimPowerSystem 67 traction drives. The motor loads systems are stable when the motor torque was equal to the load torques. The most of the motors will operated in a steady state at a fixed speed. III. IMPLEMENTATION Figure 2: Vector Control AC Motor Drives. Information about the actual speed is fed back to the controller by sensors, and the control deci- sions are implemented via a device, the actuator, that changes the position of the gas pedal. The knowledge of the car’s response to fuel increases and decreases is most often captured in a mathematical model. The vehicle dynamics control of the distributed driving electric vehicle is one of the research focuses currently, which attracts lots of scholars’ attention [8–10].
