Kind Code:
A8
Abstract:
If it is determined that a malfunction has occurred in an electrical hydraulic pump (16) and the hydraulic fluid is not supplied to a high hydraulic pressure supplied portion (3) from the electrical hydraulic pump (16), the hydraulic fluid is supplied to the high hydraulic pressure supplied portion (3) from a mechanical hydraulic pump (14) that usually supplies the hydraulic fluid to a low hydraulic pressure supplied portion (2). In this case, the hydraulic pressure that is generated by the mechanical hydraulic pump (14) is increased by increasing the output from the engine (13) that drives the mechanical hydraulic pump (14).
