SYSTEMS AND METHODS FOR CONTROLLING A VEHICLE EQUIPPED WITH START-STOP LOGIC IN RESPONSE TO VEHICLE MASS AND ROUTE GRADE
20170043777 · 2017-02-16 ·

Controls for improved drivability of a vehicle equipped with start/stop logic are disclosed. A nominal control stop for the internal combustion engine of the vehicle is disabled or prevented from occurring in response to a vehicle mass and route grade indicating a roll back condition for the vehicle exists if the nominal control stop for the engine were to take place.

Hydraulic control device

A hydraulic control device includes a C1 relay valve 70 whose state is switched based on a signal pressure that is generated based on a line pressure PL, and a check valve 80 attached to a drain oil passage L7. A set pressure of the check valve 80 is adjusted to an oil pressure that is lower than the maximum oil pressure obtained by discharge capability of an electromagnetic pump 60 and higher than an SL1 pressure Psl1 remaining in a hydraulic servo of a clutch C1 when the state of the C1 relay valve 70 is switched after a mechanical oil pump 42 is stopped. Operation of the electromagnetic pump 60 is started before the state of the C1 relay valve 70 is switched after the mechanical oil pump 42 is stopped.
