Boarding/deboarding controller

A boarding/deboarding control circuit for a vehicle, the vehicle including a seat, an occupant compartment, and a canopy, the occupant compartment including (i) an opening at least at a top of the occupant compartment, (ii) the seat inside the occupant compartment and (iii) a steering column inside the occupant compartment, the canopy being configured to move between a closed position and an opened position, the closed position being a position where the canopy closes the opening of the occupant compartment, the opened position being upper than the closed position,

• wherein the seat includes:
• a seat body including a seat cushion and a seatback;
• a pin and a locking member;
• a seat lifter actuator configured to move a rear of the seat cushion along an up-down axis by moving the locking member to be engaged with and released from the pin;
• and
• a reclining actuator configured to pivot the seatback in a direction of a seat front-rear axis relative to the seat cushion,
• wherein the boarding/deboarding control circuit is configured to start raising the steering column when the canopy reaches a first opening degree during an opened movement of the canopy from the closed position to the opened position,
• wherein, after the steering column started being raised during the opened movement of the canopy from the closed position to the opened position, the boarding/deboarding control circuit is configured (i) to drive the seat lifter actuator to raise the rear of the seat cushion such that the rear of the seat cushion becomes higher than a front of the seat cushion and (ii) to simultaneously drive the reclining actuator to pivot the seatback in a rearward direction,
• wherein the boarding/deboarding control circuit is configured to drive the seat lifter actuator to start moving the locking member to be released from the pin when the canopy reaches a second opening degree during the opened movement of the canopy, and
• wherein, when a release of the locking member is detected after the canopy reaches the second opening degree, the boarding/deboarding control circuit is configured to drive the seat lifter actuator to start raising the seat cushion and simultaneously drive the reclining actuator to start pivoting the seatback in the rearward direction.
