Clutch control device for car drive system

Abstract

Abstract PURPOSE:To prevent trend of understeering by performing control of clutch engagement force on the basis of the car speed in the low range of transverse acceleration, and performing control on the basis of the transverse acceleration in high range. CONSTITUTION:A clutch control means 4 performs control on the basis of car speed 301 with no differential limiting torque given, when the transverse acceleration 302 is under a set value, i.e. when the transverse acceleration is low due to low car speed, large radius of swinging, etc. even though it is under straight running or swinging. When on the other hand the transverse acceleration 302 exceeds the set value, i.e. a transverse acceleration is generated by any external factor such as side wind, slope, etc., the differential limiting torque is increased in accordance with the degree of generation of transverse acceleration. This can provide high-speed straight running stability, prevent intense trend of understeering in the initial period of swinging, and enhance the acceleration characteristic in later period of swinging.
