摘要:
A vehicle control device includes: an abnormality detecting portion that detects an abnormality in at least part of a shift position detection portion detecting a shift position; a shift-operatoin determining portion that determines, based on a detection signal from the shift position detection portion, whether a shift operating device is shift-operated or not by a driver, and a vehicle movement prevention control portion that, in a case where a movement of a vehicle is prevented by an actuator and in a case where the abnormality in part of the shift position detection portion is detected by the abnormality detecting portion, permits the actuator to release the prevention of the movement of the vehicle if it is determined by the shift-operation determining portion that the shift operating device is shift-operated by the driver.

When there is no malfunction in either drive shaft rotational speed detection portion (36) or rotating shaft rotational speed detection portion (44), control of internal combustion engine (22), the power split device (30, MG1), the electric motor (MG2), and the shifting portion (60) is performed while speed ratio in shifting portion (60) is changed and an intermittent operation of internal combustion engine (22) is performed so that a drive power required for drive shaft (32a) is output to shaft (32a). When a malfunction occurs in drive shaft rotational speed detection portion (36) or/and rotating shaft rotational speed detection portion (44), the control is performed while at least one of change in speed ratio, intermittent operation, and output of drive power required for shaft (32a) to shaft (32a) is limited so that a drive power that approximates required drive power as closely as possible is output to drive shaft (32a).

A D/A converter circuit which converts a digital signal of n bits into an analog signal and outputs the analog signal comprises: a plurality of D/A conversion processors, each of which converting a digital signal into an analog signal, the digital signal being made by dividing the n-bit digital signal at least into two; a plurality of output resistance regulators coupled to outputs of the plurality of respective D/A conversion processors; and an output signal generator generating the analog signal that forms an output of the D/A converter circuit based on outputs of the plurality of output resistance regulators. At least one of the D/A conversion processors is configured as a resistor string type D/A converter circuit including: a resistor string circuit which has a plurality of serially-coupled resistors and a plurality of switches, one end of each of the plurality of switches being coupled to one of coupling points of the plurality of resistors, and other ends of the plurality of switches being coupled together to form an output end; and a decode circuit which decodes the digital signal and generates a control signal that controls ON/OFF of the plurality of switches included in the resistor string circuit. Each of the plurality of output resistance regulators includes a variable resistance circuit which changes a resistance value to be substantially equal to an output resistance value of the D/A conversion processor, in accordance with a change in the output resistance value of the D/A conversion processor that is coupled to another output resistance regulator and configured as the resistor string type D/A converter circuit.
摘要:
An abnormality determination device and an abnormality determination method of a vehicle that includes a stepped type automatic transmission capable of forming a plurality of speed change steps are provided. The presence/absence of an abnormality of an element related to formation of a predetermined speed change step is determined in a state of the vehicle where the predetermined speed change step is formed. Information about the abnormality determined to be present is then stored. If the information about the abnormality is stored when the vehicle is to newly start to run, the predetermined speed change step where the abnormality stored occurred is established, and the presence/absence of the abnormality of the element related to the formation of the predetermined speed change step is re-determined.
摘要:
A control device of a hybrid vehicle including a motive power distribution mechanism that distributes output of an engine to a first motor-generator and to an output shaft, a second motor-generator that outputs power to the output shaft via a stepped type transmission, and an electricity storage device, and a control method. In an activating operation of the vehicle, a friction engagement device is engaged, and a ready-to-run state is et based on the engagement oil pressure of the friction engagement device detected. It is determined whether the vehicle is in a motor or a non-motor run region. If the vehicle is in the non-motor run region, the original pressure of the friction engagement device is set at a non-working pressure at which a hydraulic switch does not operate, as the engine is started up. After complete explosion of the engine, the original pressure is set at a working pressure at which the switch operates.

A shift control system rotates an actuator to allow a wall of a detent plate and a roller of a detent spring to contact each other and then detects the position of contact so as to detect the position of the wall of the detent plate. After the wall position is determined, the actuator is driven in the direction opposite to the wall until the actuator reaches a position located before the wall position and distant therefrom by a predetermined amount, in order to cancel flexure or extension of the detent spring that is caused when the detent spring is pushed against the wall of the detent plate. Accordingly, such a situation where the shift position is moved by the recovery force of the detent spring can be avoided.
摘要:
A pen core for a writing instrument, particularly, for use in a recorder in which writing must be continuously carried out over long periods using a relatively small ink supply. The instrument has an ink conducting core for conducting ink to a writing member, and a barrel with an ink reservoir, the barrel being fitted on the outer wall of the pen core body. An annular groove in the form of a single continuous passageway is formed in the outer wall of the pen core body, the annular groove having a front end connected to an ink sucking groove, which is in turn communicated with the ink conducting core. An air passageway having a front end communicated with an air hole and a rear end communicated with the rear end of the annular groove is formed in the outer wall of the pen core body in such a manner that the air passageway does not cross the annular groove.

摘要:
A shift control system rotates an actuator to cause a wall of a detent plate to contact a roller of a detent spring, and detects the position of contact so as to detect the position of the wall of the detent plate. This wall position is set as a reference position of the actuator. Accordingly, the rotation of the actuator can appropriately be controlled even if an encoder which can only detect relative positional information is employed, and thus the shift range can appropriately be switched.
