Abstract:
A controller for a vehicle drive system wherein an engine and a motor are connected to a drive wheel via a continuously variable transmission which increases a drive ratio according to a decrease of a rotation speed of said drive wheel, said vehicle comprising an accelerator pedal for increasing an output torque of said engine according to a depression thereof, while said engine exerts an engine brake on said drive wheel when said accelerator pedal has been released, a brake device for applying a braking pressure to said drive wheel, and an antilock brake system which decreases said braking pressure so as to prevent said drive wheel from locking, said vehicle drive system controller comprising:a first microprocessor programmed to:determine if said antilock brake system is decreasing said braking pressure, andcontrol said drive system so that the rotation torque of said motor is applied to said drive wheel when said antilock brake system is decreasing said braking pressure.
