摘要： A turning control device (50) includes a precursor detection circuit (73) configured to detect a precursor of an abnormality by which a smooth operation of a turning device (30) is impaired. The precursor detection circuit (73) is configured to start measurement of a total running time of a vehicle when the precursor is detected, and is configured to execute a process of reporting the precursor, based on the measured total running time. The precursor detection circuit (73) is configured to perform the measurement of the total running time regardless of whether the precursor is detected again, when a vehicle electric power source is switched off and then is switched on again after the precursor is detected once.

摘要： A steering control device is applied to a steer-by-wire system (901) in which a steering mechanism and a turning mechanism are mechanically separated, or an electric power steering system (902) in which the steering mechanism and the turning mechanism are mechanically coupled. A steering control device (201) applied to the steer-by-wire system (901) controls a drive of a steering motor (78) that functions as a reaction motor that applies reaction torque to a steering wheel (91). A steering wheel lock calculating unit (75) of the steering control device (201) performs a steering wheel lock drive control for calculating a drive command so as to output a lock torque for maintaining a rotation stop state of the steering wheel by energizing the steering motor (78) when a predetermined condition is satisfied while a vehicle is parked or stopped. A power converter (77) converts power supply electric power according to the drive command calculated by the steering wheel lock calculating unit (75) and supplies the electric power to the steering motor.

摘要： A vehicle power supply system includes a power source control device (88) that executes a process of switching a connection state of a driving circuit (61a) to the main power source (45) and an auxiliary power source (81) including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source (45) occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source (45) is resolved. After a voltage decrease of the main power source (45) occurs, a turning-side control device (60) of a steering control unit (1) sets an output-limited state for a turning-side motor (32). The output-limited state is canceled upon the power source control device (88) completing switching of the connection state so as to transition.

摘要： A vehicle control device includes: dual-system control circuits that control power supply to dual-system winding sets (N21, N22; N31, N32) of a motor; and dual-system rotation detection circuits. The control circuits calculate an absolute rotation angle of the motor, and, when a power source is turned off, store an absolute rotation angle of the motor at that time. The control circuits start when the power source is turned on and the absolute value of a difference between an absolute rotation angle that was stored when the power source was turned off last time and an absolute rotation angle that is calculated when the power source is turned on this time is equal to or smaller than a given threshold value, regardless of whether an abnormality has occurred in one of the dual-system rotation detection circuits or an abnormality of the dual-system rotation detection circuits is not determinable.

摘要： The present invention relates to a steering control device (50) including a controller configured to control driving of a motor (41) that generates a torque. The torque is a torque applied to a steering mechanism (12, 14) of a vehicle using electric power from at least any one of an in-vehicle main power source (71) and an auxiliary power source (70A) that backs up the main power source (71). The controller is configured to wait (S302) for the auxiliary power source (70A) to be charged to an extent that the main power source (71) is able to be backed up and to permit (S103) the vehicle to travel when the controller is activated with an activation operation for the vehicle as a trigger and transitions to a state where control of the motor is executable. The invention further relates to a corresponding power source system and vehicle.

摘要： A steering control system that controls a steering device (2) of a vehicle includes a storage unit, and a control unit configured to make a state transition to a normal control state via a start-up state after a power source system of the vehicle is started. In the start-up state, the control unit executes a correction information storing process of acquiring correction element information using a state variable obtained from the steering device (2) and writing correction information obtained based on the correction element information into the storage unit. In the start-up state, the control unit is configured to execute an abnormal condition determination process of determining whether an abnormal condition indicating that the correction information is abnormal is met. The correction information storing process is re-executed when the abnormal condition is met. The abnormal condition determination process is executed at least either before or after the correction information storing process.
