In a vehicle enabling automated driving, if the value of at least one jam related parameter changing in accordance with a jam degree of surroundings of the vehicle is a value showing a jam degree lower than a reference value corresponding to a reference jam degree, the vehicle is driven in a first driving mode, and if the value of the jam related parameter is a value showing a jam degree higher than the reference value, the vehicle is driven in a second driving mode with a lower degree of contribution of the driver to driving than the first driving mode. A notification device used in the vehicle has a notification control part showing on a display device of the vehicle a display relating to the value of the jam related parameter and the reference value.

Notification device to driver

A travel controller performs driving control of a vehicle at an autonomous driving level that is a first autonomous driving level in which a driver of the vehicle is not obligated to watch or a second autonomous driving level in which the driver is obligated to watch; notifies, for a predetermined period, the driver of a request for driving the vehicle or taking a driving posture allowing for the driving, when the autonomous driving level of the driving control changes from the first autonomous driving level to the second autonomous driving level; and determines an attention level of the driver, based on an output of a sensor provided for the vehicle. The attention level is a level of attention to driving. The travel controller further modifies the predetermined period so as to be shorter when the determined attention level is high than when the attention level is low.

Travel controller and method for travel control

An electrically-driven vehicle includes: a battery; an induction motor connected to the battery; a synchronous motor connected to the battery that is connected to the induction motor; and at least one electronic control unit configured to change a slip frequency command of the induction motor based on a predetermined frequency of current fluctuation when a temperature of the battery is low such that an amplitude of the current fluctuation increases, the current fluctuation being any one of current fluctuation of a battery current or current fluctuation of a battery-related current that relates to the battery current.

An electronic control unit includes calculating a slip frequency of a rotating electric machine from a torque instruction value to the rotating electric machine and a target value of output efficiency to the rotating electric machine, calculating a frequency of the instruction signal from the slip frequency and a rotational frequency of the rotating electric machine, the slip frequency being changed by changing the target value of the output efficiency with the torque instruction value maintained and changing the slip frequency so as to change the frequency of the instruction signal to out of an inverter lock frequency band when the frequency of the instruction signal is included in the inverter lock frequency band.

Control device of rotating electric machine and method for controlling the same

An electric vehicle driven by a synchronous motorand an induction motor, and braked with a first regenerative torque BTgenerated by the synchronous motor generatorand a second regenerative torque BTgenerated by the induction motor generator. The ratio of the first regenerative torque BTto the second regenerative torque BTis changed in accordance with a state of charge (SOC) of a battery. In this way, a switching frequency from a regenerative brake to a hydraulic brake is restricted to improve drivability when a state of charge (SOC) of the batteryis high.

Electric vehicle and control method of electric vehicle

An electric vehicle includes: a synchronous motor; an induction motor; and a control unit configured to adjust a torque from the synchronous motor and a torque from the induction motor, wherein the control unit includes a torque varying device configured to reduce an output torque from the synchronous motor while maintaining a total drive force of the electric vehicle, and increasing an output torque from the induction motor in the case where the electric vehicle is stopped in a state in which a torque is output from the synchronous motor. Accordingly, there is provided an electric vehicle capable of restraining deterioration of drivability and performing thermal protection of a motor and a control unit.

When a command frequency to a rotating electric machine is included in an inverter lock frequency band, a frequency switching section switches the command frequency to a frequency outside the inverter lock frequency band by changing a slip frequency command value. In response to this, a torque command change section changes a torque command to a second rotating electric machine other than a first rotating electric machine of which the slip frequency is changed such that a torque fluctuation caused by the change of the slip frequency command value is canceled out.

Control device and control method for vehicular rotating electric machine

A control device for an induction motor that drives a vehicle includes an electronic control unit. The electronic control unit i) controls torque of the induction motor when an inverter that controls supply of electric current to the induction motor is in a locked state, so as to release the inverter from the locked state, ii) determines whether the inverter is in the locked state, iii) controls a slip frequency of the induction motor when it determines that the inverter is in the locked state, and iv) superimposes a frequency that actual torque does not substantially respond, on the slip frequency, so that an electric frequency lies in a region outside a lock region in which the inverter is in the locked state.

A gripping jig for assembling whereby a force is applied to a molded body in a direction perpendicular to an assembling direction. When an assembling load is applied to the molded body, the force is adjustable with an adjustment screw such that the molded body is guided to move in the assembling direction. Since the force is applied from a direction different from the assembling direction, the molded body can move in the assembling direction, and since the force is adjustable, application of the assembling load to the molded body and the movement of the molded body can be adjusted. Since a plurality of the molded bodies are fixed and assembled respectively, when there are variations in size of the molded bodies, an excessive assembling load is is avoided with each molded body guided to move, so that a more uniform assembling load is applied to the plurality of molded bodies.

A gripping jig for assembling applies a force to a molded body in a direction perpendicular to an assembling direction. When an assembling load is applied to the molded body, the force is adjustable with an adjustment screw such that the molded body is guided to move in the assembling direction. Since the force is applied from a direction different from the assembling direction, the molded body can move in the assembling direction, and as the force is adjustable, application of the assembling load to the molded body and movement of the molded body can be adjusted. Since a plurality of molded bodies are fixed and assembled respectively, when there are variations in size of the molded bodies, if an excessive assembling load is applied, each molded body is guided to move, so that more uniform assembling load is applied to the plurality of molded bodies.
