Abstract
The present paper presents a proposal to improve the longitudinal performance of a land vehicle by adopting an unusual system of traction control. The system is able to improve the transfer of power from the motor to the ground and reduces the complexity of the task being executed by the driver. High-performance vehicles are able to achieve high levels of longitudinal acceleration and sometimes over-power leads to spinoff of the driving wheels, which reduces the ability of the tires to generate force and consequently acceleration of the vehicle. The proposed system acts beyond the control of the engine, through the derivation of the engine speed signal and its control in comparison with a predefined value. The control may delay or even suppress the ignition of the engine. Thus, the rate at which the engine generates speed and, consequently, the speed at which the vehicle accelerates, is limited. The benefits of the system are low cost and ease of application in a modern vehicle.
