    摘要: A traction control system for a four-wheel steerable vehicle includes a reference value generating circuit for generating a reference value for detecting a slippage of a drive wheel in a driving state, an output torque control device for controlling the torque of the drive wheel on the basis of an output from said reference value generating circuit so as to bring said drive wheel into a predetermined slipping state, and a reference value correcting circuit for correcting the reference value on the basis of a rear wheel steering angle. This makes it possible to insure a steering stability in a critical condition when a misalignment has been produced in phases of the front and rear wheels.

    摘要: A vehicle traction control device includes an engine output controller for deactivating the combustion stroke of an engine in order to control the vehicle traction, a vehicle speed judgment circuit for judging whether or not a speed detected by a vehicle speed detector is lower than a preset speed, and an engine revolution-number judgment circuit for judging whether or not a value detected by an engine revolution-number detector exceeds a preset value, wherein the vehicle speed judgment circuit and the engine revolution-number judgment circuit are connected to the engine output controller so as to deactivate the engine combustion stroke when the vehicle speed is lower than the preset speed and the number of revolution of the engine exceeds the preset value. The vehicle traction control device further includes an excessive slip detector for detecting an excessive slip in a driving wheel which is driven by the engine, a vehicle speed index output circuit for outputting an index representative of the vehicle speed, and a combustion stroke deactivating period setting circuit for reducing the rate of a period of deactivating the engine combusion stroke per revolution of the engine, caused by the engine output controller, in accordance with the index, wherein the engine output controller operates also in response to detection of an excessive slip by the excessive slip detector. Thereby excessive slip in the vehicle driving wheels is controlled so that the traction for the vehicle is prevented from deteriorating.

    摘要: A slip control method controls slip of the driving wheels of a vehicle. The method includes detecting excess slip of the driving wheels of the vehicle during acceleration, and reducing a driving force to said driving wheels upon detection of said excess slip in order to limit the slip of the driving wheels. The slip control of said driving wheels is inhibited upon detection of the application of a parking brake of the vehicle, or upon the detection of the transmission of the vehicle as being in the reverse gear position.
