Motor vehicle traction control preventing wheel spin - adjusts output load delivered by engine with reduced adjustment rate for stationary vehicle

摘要

The traction control allows the engine load to be adjusted to control the drive torque delivered to the driven vehicle wheels so that the detected wheel slip attains the required slip value. The control device for adjusting the engine load allows the load to be increased or reduced at a slower rate when the vehicle is at a standstill. Pref., the traction control uses an auxiliary throttle plate (45) in the air intake, in series with the main throttle plate (43) controlled by the accelerator pedal. USE - Maintaining traction on muddy road surface.
