Document Type and Number:
Japanese Patent JP2620310
Kind Code:
B2
Abstract:
A traction control system or the anti-lock brake system comprises a wheel behaviour detecting system which comprises a coefficient calculating circuit (5) for calculating, on the basis of output values from wheel speed detectors (1-4), a coefficient A of bad road representative of the surface irregularity of the road on which the vehicle is moving, and a control variable filtering circuit (7) operable to a filtered value Lm which exhibits a waveform similar to the original waveform of the control variable F when the bad road coefficient A is small, but a waveform in which a component of abrupt change of the control variable F is removed when the bad road coefficient is great. With the wheel behaviour detecting system used in the traction control system or the anti-lock brake system, a control command determining circuit (8) is operable in response to the output from the filtering circuit (7), that is, the control variable which has been modified, to determine the command necessary to control braking forces to be applied to the wheels.
