摘要:
Power is supplied to an ECU (20) from an on-vehicle battery (41). When an ignition switch (42) is switched from the OFF state to the ON state upon vehicle engine start, the ECU (20) is switched from the power saving mode to the normal mode and a CPU (31) executes initial processing. Moreover, when a user puts on a seat belt and a seat belt switch (44) is switched from the ON state to the OFF state, the ECU (20) is switched from the power saving mode to the normal mode and the CPU (31) executes the initial processing. Thus, the initial processing is executed at a comparatively short interval and it is possible to improve the reliability of the CPU (31).

An information request portion receives an information request signal transmitted to an information response portion at its own receiving port. The information request portion comprises at least either of a power supply system anomaly determination portion or a ground anomaly determination portion. The power supply system anomaly determination portion determines a short-circuit between a signal line and a power supply system in a case where the information request signal received at the receiving port is always fixed to a H (high) level. The ground anomaly determination portion determines a short-circuit between a signal line and a ground in a case where the information request signal received at the receiving port is always fixed to a L (Low) level. Consequently, the anomaly region of the signal line connecting the information request portion and the information response portion in such a manner that bidirectional digital communications are possible or the cause of the anomaly is specified.

A headrest control apparatus for a vehicle includes: a headrest rear portion; a headrest front portion movable relative to the headrest rear portion between a first position and a second position; driving means for moving the headrest front portion relative to the headrest rear portion and controlling means controlling the driving means to move the headrest front portion towards the second position when a proximity of an object from a rear of the vehicle is detected and stop a movement of the headrest front portion towards the second position when the head detecting circuit detects the one of a proximity of the head towards, and a contact of the head with, the headrest front portion. The controlling means operates the head detecting circuit when the headrest front portion moves towards the second position.

A vehicle occupant discrimination apparatus is provided, which is capable of precisely discriminating a vehicle occupant using load data detected by a small number of load sensors for detecting a load applied to a vehicle seat. In a vehicle occupant discrimination apparatus for discriminating the kind of an occupant on a vehicle seat on the basis of the load applied to the vehicle seat, the apparatus includes state detecting means for detecting the occupant state on the vehicle seat, load measuring means for measuring the load applied to the vehicle seat, and discriminating means for discriminating the kind of the occupant on the basis of a discrimination condition differing in accordance with the result detected by the state detecting means and the result measured by the load measuring means.

An occupant judging device for a vehicle seat includes a load sensor provided in the vehicle seat and a controller for calculating a detected load value based on an output load value from the load sensor and determining an occupant on the vehicle seat by comparing the detected load value and a predetermined threshold value. The controller judges by a decrease state of the detected load value detected after the seatbelt is fastened being maintained for a first predetermined time that a child restraint device is installed, when a state in which the seatbelt is fastened and the door is opened is detected. Further, the controller judges by a decrease state of the detected load value detected after the seatbelt is fastened being maintained for a second predetermined time that the child restraint device is installed, when a state in which the seatbelt is fastened and the door is closed is detected.
摘要:
An occupant determining device includes a load detecting sensor provided on a seat body and a controller. The controller calculates a detected load value based on an output value of the load detecting sensor and performs occupant determination based on the detected load value. The occupant determination state is switched to an adult determination state when a certain delaying time elapses after the detected load value exceeds a first determination threshold. The controller sets the delaying time shorter when the detected load value exceeds the first determination threshold within a predetermined time after the detected load value exceeds a second determination threshold.
