Control apparatus for use with driving device of vehicle
First Claim
1. A control apparatus for use with a driving device of a vehicle, the driving device including (A) a non-step speed change portion which includes (a1) a differential device that distributes an output of an engine to a first electric motor and a transmission member, and (a2) a second electric motor that is provided in a power transmission path from the transmission member to a plurality of drive wheels, and which is operable as an electric, continuously variable transmission, and (B) an automatic speed change portion which constitutes a portion of the power transmission path and functions as an automatic transmission, the control apparatus comprising:
- a vehicle behavior stabilization controller which is for stabilizing a behavior of the vehicle when the behavior of the vehicle is unstable;
a coupling device which is selectively switchable to (a) a released state thereof in which the coupling device places the non-step speed change portion in a non-step speed change state thereof in which the non-step speed change portion is operable as the electric continuously variable transmission, and (b) an engaged state thereof in which the coupling device places the non-step speed change portion in a stepwise speed change state thereof in which the non-step speed change portion is not operable as the electric continuously variable transmission; and
a vehicle-stabilization-related switching controller which switches, when the vehicle behavior stabilization controller performs a vehicle behavior stabilization control, the coupling device to the released state thereof.

Abstract
A control apparatus for a vehicle'"'"'s driving device including (A) a non-step speed change portion including (a1) a differential device that distributes an output of an engine to a first electric motor and a transmission member, and (a2) a second electric motor provided in a power transmission path from the transmission member to drive wheels, and (B) an automatic speed change portion constituting a portion of the power transmission path, the control apparatus including a vehicle behavior stabilization controller for stabilizing a behavior of the vehicle when the behavior of the vehicle is unstable; a coupling device which is selectively switchable to (a) a released state thereof in which the coupling device places the non-step speed change portion in a non-step speed change state thereof in which the non-step speed change portion is operable as an electric CVT (continuously variable transmission), and (b) an engaged state thereof in which the coupling device places the non-step speed change portion in a stepwise speed change state thereof in which the non-step speed change portion is not operable as the electric CVT; and a vehicle-stabilization-related switching controller which switches, when the vehicle behavior stabilization controller performs a vehicle behavior stabilization control, the coupling device to the released state thereof.

2. A control apparatus for use with a driving device of a vehicle, the driving device including a power transmission device which includes (a1) a differential device that distributes an output of an engine to a first electric motor and a transmission member, and (a2) a second electric motor that is provided in a power transmission path from the transmission member to a plurality of drive wheels, and which is operable as an electric differential system, the control apparatus comprising:
-
a vehicle behavior stabilization controller which is for stabilizing a behavior of the vehicle when the behavior of the vehicle is unstable; a coupling device which is associated with the differential device and which is for selectively switching the differential device to (a) a differential state thereof in which the differential device exhibits a differential function and to (b) a locked state thereof in which the differential device does not exhibit the differential function; and a vehicle-stabilization-related switching controller which operates, when the vehicle behavior stabilization controller performs a vehicle behavior stabilization control, the coupling device to switch the differential device to the differential state thereof. - View Dependent Claims (13, 15, 16, 17, 18, 19, 20, 21, 22, 23, 26, 28)
