TRACTION CONTROL DEVICE FOR VEHICLE

摘要

PURPOSE:To reduce the size of a control system to a comparatively lower value and to improve responsiveness of control and hysteresis characteristics, in a traction control device for a vehicle which is provided with a control unit to actuate a wheel brake for right and left drive wheels, connected to a power source through a differentiating device, when an excessive slip tendency occurs during acceleration of a vehicle. CONSTITUTION:Input torque from a power source to a differentiating device is detected by an input detecting means 41. Limit drive torque is determined based on the detecting value of an input detecting means 41 when it is detected by a slip detecting means 40 that only one of two drive wheels is brought into an excessive slip tendency. Brake torque exerted on one drive wheel is determined based on a value obtained by subtracting the limit drive torque from a present detecting value of an input torque detecting means 41.
