Abstract

Each of a plurality of ECUs 1 has a common key (Ky). Each ECU 1 generates a block at certain time intervals, for example. The block includes a signature value obtained by encrypting, with the common key, original data including a previous signature value, which is the signature value of a last block, and a transaction. Thus, previous and subsequent blocks are associated with each other. Each ECU 1 delivers the generated block to each other ECU 1 and requests verification. ECU 1, upon receiving the block generated by another ECU 1, verifies authenticity using the common key, and transmits a result. Each ECU 1 links the block of which authenticity has been confirmed by a majority of the ECUs 1 with a blockchain. If a block is generated simultaneously by a plurality of ECUs 1, each issues a verification request after waiting for a random period of time.

Abstract

A fuel pressure control system (91, 92) that controls the fuel pressure of a fuel supply system (90f) that supplies fuel to an injector (35) of an engine (90). The fuel pressure control system has a pressure-raising pump (29) that raises the fuel pressure (P) of a high-pressure system (30) that is a part of the fuel supply system, a pressure-reducing mechanism (37) that reduces the pressure of the high-pressure system, and a control device (50). When a discharge abnormality (A) occurs at the pressure-raising pump and the fuel pressure of the high-pressure system begins to rise, the pressure-reducing mechanism performs an abnormality countermeasure (Ac) to stop the rise in the fuel pressure of the high-pressure system. When it has been determined that the fuel pressure control system is in a caution-required state (Wq) in which, were a discharge abnormality to occur, the fuel pressure of the high-pressure system could exceed a threshold pressure (Px) that is at or below the pressure resistance of the high-pressure system by the time the rise in the fuel pressure is stopped by the abnormality countermeasure, the control device puts the fuel pressure control system into an alert state (W) in which, even if a discharge abnormality occurs, the fuel pressure of the high-pressure system will not exceed the threshold pressure by the time the rise in the fuel pressure is stopped by the abnormality countermeasure.

Abstract

On the basis of a change in a magnetic field that is constantly received by a detecting element (107) from a detection body (200) consisting of a magnetic body, in conjunction with the movement of the detection body, a detecting unit (101) generates a detection signal corresponding to a plurality of ranges arranged in one direction in the direction of movement of the detection body. A signal processing unit (102) acquires the detection signal from the detecting unit, compares the detection signal with a threshold, and identifies the position of the detection body as the position of any one of the plurality of ranges, on the basis of a combination of magnitude relationships between the detection signal and the threshold. The detection body has a plurality of region portions (201 to 203) corresponding to the plurality of ranges. The plurality of region portions are configured by being connected in a stepwise manner in the direction of movement of the detection body, within the plane of a detecting surface (205) of the detection body that faces the detecting unit. If the detection body is missing, the signal processing unit determines that the detection body is missing by acquiring the detection signal that is completely unaffected by the magnetic field from the detection body.

Abstract

This sleep control apparatus is for controlling sleep of a subject (12), and comprises a sleep onset control unit (S107) and a sleep maintenance control unit (S108). The sleep onset control unit sends the subject into sleep and causes the sleep depth of the subject to transition to stage 1 or stage 2, by applying prescribed stimuli capable of inducing the subject to sleep by a stimulation device (31). The sleep maintenance control unit enables the subject to maintain sleep while keeping the subject's sleep depth within a range between stage 1 and stage 2, by applying prescribed stimuli for allowing the subject to maintain sleep through the stimulation device after the subject has been brought into sleep by the sleep onset control unit. In addition, while the subject is asleep, the sleep maintenance control unit causes the stage-2 sleep depth to emerge in such a manner as to make a first cumulative time, which is calculated by summing up the durations in which the sleep depth of the subject was maintained in stage 1, longer than a second cumulative time, which is calculated by summing up the durations in which the sleep depth of the subject was maintained in stage 2.

Abstract

A HUD (100) is a display device for virtual image which displays a virtual image (Vi) visible to a driver of a vehicle (A). The HUD (100) uses an actuator to switch the position of a viewing angle (VA) at which the virtual image (Vi) is displayed among a plurality of positions including a normal position (VP1) and an overlapping position (VP2). The HUD (100) displays the virtual images (Vi) linked to the normal position (VP1) and the overlapping position (VP2), respectively, in response to the switching of the position of the viewing angle (VA) by the actuator. Moreover, when a specific content (CTis) is to be displayed within the viewing angle at the overlapping position (VP2) after the viewing angle (VA) is moved from the normal position (VP1) to the overlapping position (VP2), the HUD (100) starts the display of an associated content (CTr) associated, in advance, with the specific content (CTis) before completion of the movement of the viewing angle (VA) to the overlapping position (VP2).

Abstract

This motor control device drives a first motor (71) and a second motor (72) that output torque in a braking direction or a non-braking direction, depending on a conducting direction. A power converter (45) has a first leg (51), a second leg (52), and a third leg (53), which are connected in parallel. The first motor (71) and the second motor (72) are configured to output torque in the same direction, either the braking direction or the non-braking direction, when a control unit (40) passes current from a positive-side switch element (S1H) of the first leg to a negative-side switch element (S2L) of the second leg and passes current from a positive-side switch element (S3H) of the third leg to the negative-side switch element (S2L) of the second leg. When current that is flowing or is predicted to flow to the first motor and/or the second motor has an absolute value that exceeds a current threshold value, the control unit (40) drives switching of a positive-side switch element (S2H) and the negative-side switch element (S2L) of the second leg.

Abstract

This steering control device is applied to a steer-by-wire system (901) in which a steering mechanism and a turning mechanism are mechanically separate, or to an electric power steering system (902) in which a steering mechanism and a turning mechanism are mechanically coupled. A steering control device (201) applied to the steer-by-wire system (901) controls the driving of a steering motor (78) that functions as a reaction force motor that imparts a reaction torque to a steering wheel (91). When a prescribed condition is met while a vehicle is stopped or parked, a steering wheel lock calculation unit (75) of the steering control device (201) performs a "steering wheel lock driving control" that calculates a driving instruction to output a locking torque for keeping the rotation of the steering wheel locked by supplying electrical power to the steering motor (78). A power converter (77) converts power from a power supply according to the driving instruction calculated by the steering wheel lock calculation unit (75), and supplies the converted power to the steering motor.

Abstract

When a predetermined stop condition is satisfied in a case where a mode determination unit (112) has determined that a mode is a steady mode, a feedback control adjustment unit (126) can shift the mode to a control stop mode for stopping feedback control of an actuator (2) by a feedback control unit (121). When the mode is to be shifted to the control stop mode, the feedback control adjustment unit (126) stores an integration operation value obtained in the feedback control immediately before the feedback control of the actuator (2) by the feedback control unit (121) is stopped. After that, when a predetermined restart condition is satisfied, the feedback control adjustment unit (126) can restart the feedback control of the actuator (2) by the feedback control unit (121) through the use of the stored integration operation value.
