Title:
VEHICULAR DRIVE FORCE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3509558
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the deterioration of an operability by the effect of a target engine torque calculation error when the integral control of an engine and a continuously variable transmission is a high torque.
SOLUTION: In this control device, a request axle drive torque T0* is found out from an acceleration pedal operation amount APS and car speed VSP 31 and a target speed change ratio i* for a target transmission input number of rotation Ni* for generating this T0* by the lowest fuel consumption under the car speed VSP is found out 32 in order to contribute to a speed change control. A first target engine output torque Te1 for T0* by dividing T0* by a torque converter torque ratio (t) 42 and speed change ratio (i) 43 in order is found out and a second target engine output torque Te2* corresponding to APS is searched from APS and engine number of rotation Ne 46. When Te1* is a set torque Tes or more, Te1* is made to the target engine output torque Te* and when it is less than Tes, Te2* is made to Te* 47. A target throttle opening TVO* for generating Te* is found out 49 and the engine 1 is controlled by the throttle toward TVO*.
