  • Publication number: 20220258617
    Abstract: Provided is an electric vehicle control method. The electric vehicle control method includes: a disturbance torque estimation process of calculating a disturbance torque estimation value including an influence of a road surface gradient; a speed parameter acquisition process of acquiring a speed parameter relating to a vehicle speed; a stop process of calculating a stopping basis torque target value so as to converge a torque command value to the disturbance torque estimation value in accordance with a decrease of a speed parameter; and a vibration damping process of calculating a stopping correction torque target value by performing filterring on the stopping basis torque target value.

  • Patent number: 10998682
    Abstract: A connector (1) forms an internal space (13) for accommodating a circuit board (12) and a case (11). The connector (1) includes first terminals (2), a first core (5), second terminals, a second core, a housing (8) and a ventilation path (14). The first core (5) holds the first terminals (2) while exposing both ends. The second core faces and overlaps the first core (5). The second core holds the second terminals while exposing both ends. The housing (8) covers at least parts of the first and second cores. The ventilation path (14) allows the internal space (13) to communicate with outside air. At least a part of the ventilation path (14) is constituted by a groove portion (512) in at least one of overlapping surfaces of the first and second cores (5) overlapping each other. The groove portion (512) has a bent shape in the overlapping surface.

  • Patent number: 10971848
    Abstract: A connector (1) is mounted on a case (12) including an internal space (120) accommodating an electronic board (11). The connector (1) includes first terminals (3), a first core (4), second terminals (5), a second core (6), a housing (7) and a ventilation passage (8). The ventilation passage (8) allows the internal space (120) of the case (12) to communicate with outside air. At least a part of the ventilation passage (8) is constituted by a groove (40) formed in at least one of mutually overlapping surfaces (411, 611) of the first core (4) and the second core (6). An outer vent (81) of the ventilation passage (8) is formed at a position closer to the case (12) than the receptacle (71) in a Z direction.
