Abstract
An automotive vehicle seat adjusting system according to this invention is constructed to move a seat by a drive circuit. It is also constructed to allow a driver to change, during movement of the seat, the moving speed of the seat as he likes. In the system of this invention, when a signal indicative of the feeling of the driver to the moving speed of the seat is inputted, fuzzy inference is performed in accordance with a speed decision rule to decide an optimal moving speed. The optimal moving speed is decided by a fuzzy inference processor on the basis of the inputted feeling signal and an actual moving speed. The drive circuit is controlled in accordance with the decision at the fuzzy inference processor, whereby the seat is allowed to move at the optimal moving speed.
Claims17
An automotive vehicle seat adjusting system comprising:
- a drive circuit for moving an automotive vehicle seat;
- a detection circuit for detecting a moving speed of the seat;
- a feeling signal input means for inputting a signal indicative of the feeling of a driver to the moving speed of the seat;
- a rule memory with speed decision rules stored therein;
- a fuzzy inference processor for performing fuzzy inference in accordance with one of the rules stored in the rule memory to decide an optimal seat moving speed on the basis of the moving speed detected by the detection circuit and the signal inputted by the feeling signal input means;
- and
- a controller for controlling the drive circuit so that the seat can move at the optimal moving speed decided by the fuzzy inference processor.
An automotive vehicle seat adjusting system comprising:
- a drive circuit for moving an automotive vehicle seat;
- a detection circuit for detecting a position and moving speed of the seat;
- a feeling signal input means for inputting a signal indicative of the feeling of a driver to the moving speed of the seat;
- a data memory with seat position data stored therein;
- a rule memory with speed decision rules stored therein;
- a fuzzy inference processor for performing fuzzy inference in accordance with one of the rules stored in the rule memory to decide an optimal seat moving speed on the basis of the moving speed detected by the detection circuit and the signal inputted by the feeling signal input means;
- and
- a controller for writing the position of the seat, which has been detected by the detection circuit, as a position datum in the data memory, for reading a position datum stored in the data memory and then to control the drive circuit to move the seat to the position of the position datum, and also for controlling the drive circuit so that the seat can move at the optimal moving speed decided by the fuzzy inference processor.
A vehicle seat adjustment system comprising:
- a plurality of manually operable switches by which control signals may be entered by a user;
- a drive circuit for moving the vehicle seat;
- a controller coupled to said switches and said drive circuit;
- and
- an inference processor coupled to the controller.
