A driving evaluation device includes: an acquisition unit that acquires at least one of vehicle information related to a vehicle state and driving information related to a driving state of drivers; a determination unit that determines whether a predetermined failure operation related to driving has been performed based on at least one of the vehicle information and the driving information acquired by the acquisition unit; and a calculation unit that calculates a failure operation probability that is a probability that the failure operation was performed, based on the failure operation determined by the determination unit, and uses a Z score of the failure operation probability calculated based on the failure operation probability to calculate an evaluation value related to the driving of the drivers.

Driving evaluation device, driving evaluation method, and driving evaluation program

An information processing device includes: a decision unit that decides upper limits of respective individual evaluation values for a plurality of calculation items such that a total of the upper limits is a previously determined value, the individual evaluation values being relevant to driving of a driver, the calculation items being calculation items for which the individual evaluation values are calculated; an acquisition unit that acquires vehicle information relevant to a vehicle; a calculation unit that calculates the respective individual evaluation values for the calculation items within the upper limits decided by the decision unit, based on the vehicle information acquired by the acquisition unit; and a control unit that displays, on a display unit, the respective individual evaluation values for the calculation items that are calculated by the calculation unit and a total evaluation value that is a total of the respective individual evaluation values for the calculation items.

Information processing device, information processing method and information processing program

A display control device includes one or more processors configured to: acquire information regarding a plurality of driving evaluation items set in advance; count, as the number of times of measurement, the number of times that at least one of a vehicle state and a driving state meets each of the driving evaluation items while a driver is driving a vehicle; display the driving evaluation items in a display region in a vehicle cabin; and visually display information relating to the remaining number of times that is a difference between the permissible number of times set for each of the driving evaluation items and the number of times of measurement.

Display control device and display control method

A driving assistance system performs a driver-initiative normal driving assistance mode as a driving assistance for a vehicle. The system includes a reaction force characteristics change unit configured to change reaction force characteristics of the operation device, if it is determined that the operation amount of the driver is not included in the appropriate operation amount range in the normal driving assistance mode, an explicit risk determination unit configured to determine whether or not an explicit risk is present based on the external environment of the vehicle, and a driving assistance switching unit configured to switch a driving assistance for the vehicle from the normal driving assistance mode to a system-initiative risk avoidance assistance mode, if it is determined by the explicit risk determination unit that the explicit risk is present in the normal driving assistance mode.

Driving assistance system

A display control device includes an acquisition unit configured to acquire a browsing history including a record indicating that vehicle driving information corresponding to each of a plurality of display elements was displayed on the display unit of each of the driver of a vehicle and a manager who manages the driver, an identification unit configured to identify a specific element from among the display elements based on the difference between the number of browses by the driver and the number of browses by the manager that are recorded in the browsing history acquired by the acquisition unit, and a display control unit configured to cause the display unit of at least one of the driver and the manager to display the specific element with the display form of the specific element, identified by the identification unit, made different from the display form of the other display elements.

Display control device, display control method, and display control program

A driving assistance apparatus predicts an appropriate operation amount which is an operation amount performed by a driver in correspondence with the external environment, and sets the appropriate operation amount range including the appropriate operation amount, an appropriate operation amount range including the appropriate operation amount, and changes the reaction force characteristics of the operation device when it is determined that the operation amount of the driver corresponding to the prediction time point of the appropriate operation amount is not included in the appropriate operation amount range.

Driving assistance apparatus

To provide a walking assist device which can apply torque to a knee joint at a suitable timing. A walking assist device includes an actuator, a reaction force sensor and an angle sensor. The walking assist device is fitted to a user's leg. The actuator is able to apply torque to a knee joint of one leg of the user. The reaction force sensor detects a reaction force that the foot of the one leg receives from the floor. The angle sensor detects a hip joint angle of the one leg around a pitch axis. The walking assist device specifies a timing to start applying the torque to the knee joint in a direction that swings the lower leg backward, based on the detected reaction force and the detected hip joint angle.

Walking assist device

A walking assist device which assists walking motion of one of the legs of the human with a sensor attached only to the one leg is provided. The walking assist device having an actuator, a sensor, and a controller. The sensor detects a knee joint angle and a hip joint angle of the one leg. The controller stores a first target trajectory for the knee joint angle and a second target trajectory for the hip joint angle. The controller controls the actuator so that the detected knee joint angle follows the first target trajectory. Further, the controller compares time series data of the detected hip joint angle with the second target trajectory while the one leg is in a stance phase. The controller calculates a time difference between the time series data and the second target trajectory and modifies the first target trajectory based on the time difference.

A leg assist device having an abnormality management procedure which appropriately adapts to an abnormal situation is provided. The leg assist device is provided with a leg attachment and a controller. The leg attachment comprises upper and a lower links connected with a rotary joint, and an actuator. The upper link is to be attached to the upper leg of the user. The lower link is to be attached to the lower leg of the user. The actuator swings the lower link relative to the upper link. The controller outputs the commands so that the swing angle of the lower link follows a target trajectory. Further, the controller executes a first abnormality management process in which the controller shuts off torque transmission from the actuator to the user when the controller detects an abnormality before outputting the commands to the actuator.

Leg assist device

A leg assist device with a control law suitable for assisting standing up motion is provided. The leg assist device is provided with an upper leg link, a lower leg link, a rotary joint, and a controller. The upper leg link and the lower leg link is attached to a leg of a user. The rotary joint rotatably connects the lower leg link to the upper leg link. The rotary joint also has an actuator which rotates the lower leg link. The controller controls the actuator so that the lower leg link angle matches a target angle. The controller has a torque limiter that limits the magnitude of the command torque that is output to the actuator. The controller sets a standing position angle corresponding to a user's standing position to the target angle, and raises an upper limit of the torque limiter as a user's hip height rises.
