Front and rear drive power distribution control device for vehicle

摘要

With a drive power distribution control section (30), limited differential torque correction value (TLSDS) is estimated and calculated by a limited differential torque correction value calculating section (30h) based on input torque (TCD). Also, a transfer torque calculating section (30i) calculates transfer torque (TLSD2) by multiplying input torque sensing transfer torque (TLSD1) by vehicle slip angular velocity correction coefficient (K(d²/dt)). A transfer torque correction/output section (30j) then subtracts limited differential torque correction value (TLSDS) from the transfer torque (TLSD2) to calculate and output transfer torque (TLSD). In this way, clutch engaging torque for carrying out front and rear drive power distribution is set with good accuracy, and it is possible to have both high cornering performance and high traction performance.
