助装置。[Claims for Utility Model Registration] (1) An accelerator switch that operates when it detects that the accelerator operating member is not operated, a stop sensor that operates when it detects that the wheels have stopped, and a parking brake mechanism that detects that the parking brake mechanism is not operated. When the parking switch operates by detecting the opening of the door, the door switch operates by detecting the door opening operation, the accelerator switch, the stop sensor, and the parking switch operate as described above, the brake mechanism is controlled to maintain the brake pressure, and the brake mechanism is controlled to maintain the brake pressure. and a brake control means for controlling the brake mechanism to release the sustained state when the brake pressure holding state is maintained by the operation of the door switch and at least one of the accelerator switch or the parking switch is deactivated. A slope starting assist device characterized by: (2) The slope starting assist device according to claim 1, further comprising an alarm means that is activated when the brake pressure holding state of the brake mechanism is maintained.
