Title: Controller for vehicle lockup clutch
Inventor: URAGAMI YOSHIO
IPC: B60W10/10
Filed: 1988-02-09
Abstract: PURPOSE:To engage a lockup clutch a little earlier and secure a yet more powerful accelerating characteristic by changing a car speed, where the lockup clutch is made to come into a state of being engaged, to be somewhat lowish when accelerator opening and its increase rate are more than the specified value. CONSTITUTION:An accelerator opening detecting means and an accelerator opening increase ratio detecting means are installed in a controller for a lockup clutch of a vehicle, whose engine torque characteristic at engine speed corresponding to a car speed, where the lockup clutch is made to come into a state of being engaged, is a right-handed decline. When accelerator opening is more than the specified value, and its increase ratio is more than the specified value, that is, an driver intends to secure high power capacity, the car speed, where the lockup clutch is made to come into a state of being engaged, is changed to be somewhat low by a lockup clutch engaging point changing means, whereby the lockup clutch is engaged a little earlier correspondingly. Thus, using such a range that is high in engine torque, a yet more powerful accelerating characteristic is securable.
