Vehicle seat control device
This vehicle seat control device is provided with a storage unit, a position detection unit, a control unit, and an operation order setting unit. The space on a seat occupied by a passenger sitting in the seat is a sitting passenger-occupied space, and during the execution of an automatic operation, the operation order setting unit is configured to set the operation order such that position adjustments of seat elements operated in the direction of advancing into the sitting passenger-occupied space are started at the same time as, or are started after, the starting of the position adjustments of the seat elements operated in the direction moving away from the sitting passenger-occupied space.
1. A vehicle seat controller comprising:
circuitry configured to:
store a predetermined seat position that is a position of a seat set in advance;
detect positions of a plurality of seat elements of which positions are adjusted by a driving force from a driving source;
perform an automatic operation to automatically adjust the position of each of the plurality of seat elements so that each of the plurality of seat elements is moved to a position corresponding to the predetermined seat position when predetermined conditions are satisfied; and
set an operation order for the plurality of seat elements in a case where the circuitry adjusts the positions of the plurality of seat elements in the automatic operation,
wherein a region on the seat occupied by a vehicle occupant seated on the seat is referred to as a seated vehicle occupant occupying region, and
wherein the circuitry is configured to set the operation order based on whether the plurality of seat elements are respectively configured to move in a direction extending into the seated vehicle occupant occupying region or in a direction extending away from the seated vehicle occupant occupying region so that position adjustment of one of the plurality of seat elements moved in a direction extending into the seated vehicle occupant occupying region always starts simultaneously with or after position adjustment of one of the plurality of seat elements moved in a direction extending away from the seated vehicle occupant occupying region when the automatic operation is performed.
2. The vehicle seat controller according to claim 1 , wherein:
the plurality of seat elements include a seat cushion, of which position is adjusted through a tilting operation including movement in a vehicle vertical direction, and a seat back, of which position is adjusted through a reclining operation including movement in a vehicle front-rear direction;
the circuitry is configured to set the operation order when the circuitry adjusts the position of the seat back in a frontward direction and the position of the seat cushion in a downward direction so that position adjustment of the seat back in the frontward direction starts simultaneously with or after starting position adjustment of the seat cushion in the downward direction; and
the circuitry is configured to set the operation order when the circuitry adjusts the position of the seat back in a rearward direction and the position of the seat cushion in an upward direction so that position adjustment of the seat cushion in the upward direction starts simultaneously with or after starting position adjustment of the seat back in the rearward direction.
3. The vehicle seat controller according to claim 2 , wherein:
when adjusting the position of the seat back in the frontward direction and the position of the seat cushion in the downward direction, the circuitry is configured to start position adjustment of the seat back in the frontward direction after completing position adjustment of the seat cushion in the downward direction; and
when adjusting the position of the seat back in the rearward direction and the position of the seat cushion in the upward direction, the circuitry is configured to start position adjustment of the seat cushion in the upward direction after completing position adjustment of the seat back in the rearward direction.
4. The vehicle seat controller according to claim 1 , wherein:
the plurality of seat elements include a seat back, of which position is adjusted through a reclining operation including movement in a vehicle front-rear direction, and a headrest, of which position is adjusted through a front-rear operation including movement in the vehicle front-rear direction;
when the circuitry adjusts the position of the seat back in a frontward direction and the position of the headrest in a rearward direction, the circuitry is configured to set the operation order so that position adjustment of the seat back in the frontward direction starts simultaneously with or after starting position adjustment of the headrest in the rearward direction; and
when the circuitry adjusts the position of the seat back in the rearward direction and the position of the headrest in the frontward direction, the circuitry is configured to set the operation order so that position adjustment of the headrest in the frontward direction starts simultaneously with or after starting position adjustment of the seat back in the rearward direction.
5. The vehicle seat controller according to claim 4 , wherein:
when adjusting the position of the seat back in the frontward direction and the position of the headrest in the rearward direction, the circuitry is configured to start position adjustment of the seat back in the frontward direction after completing position adjustment of the headrest in the rearward direction; and
when adjusting the position of the seat back in the rearward direction and the position of the headrest in the frontward direction, the circuitry is configured to start position adjustment of the headrest in the frontward direction after completing position adjustment of the seat back in the rearward direction.
6. The vehicle seat controller according to claim 1 , wherein:
the plurality of seat elements include a shoulder support, which is arranged at a shoulder portion of a seat back and of which position is adjusted through a front-rear operation including movement in a vehicle front-rear direction, and a headrest, of which position is adjusted through a front-rear operation including movement in the vehicle front-rear direction;
when the circuitry adjusts the position of the shoulder support in a frontward direction and the position of the headrest in the frontward direction, the circuitry is configured to set the operation order so that position adjustment of the headrest in the frontward direction starts simultaneously with or after starting position adjustment of the shoulder support in the frontward direction; and
when the circuitry adjusts the position of the shoulder support in a rearward direction and the position of the headrest in the rearward direction, the circuitry is configured to set the operation order so that position adjustment of the shoulder support in the rearward direction starts simultaneously with or after starting position adjustment of the headrest in the rearward direction.
7. The vehicle seat controller according to claim 6 , wherein:
when adjusting the position of the shoulder support in the frontward direction and the position of the headrest in the frontward direction, the circuitry is configured to simultaneously start position adjustment of the shoulder support and the headrest in the frontward direction; and
when adjusting the position of the shoulder support in the rearward direction and the position of the headrest in the rearward direction, the circuitry is configured to simultaneously start position adjustment of the shoulder support and the headrest in the rearward direction.
