An information processing device configured to calculate a feature related to driving of a vehicle includes a first processor configured to receive input information including information on a speed of the vehicle and a second processor configured to calculate the feature by using the input information received during a first period in which predetermined conditions are satisfied. The first period being included in a second period in which the input information is received. The predetermined conditions include a condition that a driving operation is performed before a brief stop of the vehicle.

Information processing device, vehicle, information processing system, information processing method, and non-temporary storage medium

A brake ECU executes a process including the steps of: acquiring input information; determining whether predetermined conditions are met; when the predetermined conditions are met, acquiring vehicle speed data; updating a vehicle speed frequency distribution using the acquired vehicle speed data; and sending the updated vehicle speed frequency distribution to a data center.

Information processing device, vehicle, and information processing system

An information processing device includes a processor. The processor acquires an operation amount for acceleration/deceleration of a first vehicle by a driver of the first vehicle. The processor acquires an inter-vehicle distance from the first vehicle to a second vehicle traveling ahead of the first vehicle. The processor determines whether the operation amount meets a first specific condition determined in advance. The processor determines whether the inter-vehicle distance meets a second specific condition determined in advance. The processor calculates a diagnosis result about the inter-vehicle distance based on the inter-vehicle distance acquired when the processor determines that both the first specific condition and the second specific condition are met. The processor outputs the diagnosis result.

Information processing device

An information processing method includes determining whether at least one condition is satisfied, and calculating a feature quantity on flexibility of a tire when all of the at least one condition is satisfied. The at least one condition includes at least one of a first condition that an absolute value of an angular velocity of a steering wheel is smaller than a first reference value, and a second condition that an absolute value of a vector sum of vehicle accelerations of the vehicle including the steering wheel and wheels each provided with the tire is smaller than a second reference value.

Information processing device, vehicle, information processing method, and non-transitory storage medium

The vehicle control device includes an arbitration unit configured to arbitrate between a plurality of control commands acquired from a plurality of driving support applications that respectively implements driving support functions, configured to output instructions based on a control command after arbitration to a first control unit that is able to control a steering actuator and a second control unit that is able to control at least one of a brake actuator or a drive actuator, and configured to acquire a steering angle and a yaw rate as the control commands from the driving support applications.

Vehicle control device

A vehicle information processing method for calculating a feature related to an operation of a vehicle includes: receiving input information including at least one of information on a driving operation performed on the vehicle, information on an operating state of driver assistance of the vehicle, and information on a behavior of the vehicle; and calculating the feature by using the input information received during a predetermined period in which a predetermined condition is satisfied out of a period in which the input information is received. The predetermined condition includes a condition that a driving situation of the vehicle is a predetermined driving situation corresponding to the feature.

System, method, and program for vehicle deterioration detection

A wheel state obtaining system configured to obtain a wheel state that is a state of at least one of a plurality of wheels of a vehicle includes: a wheel speed detection device configured to detect a wheel speed of each of the plurality of wheels; a traveling state detection device configured to detect a traveling state of the vehicle; and a controller. When the traveling state of the vehicle detected by the traveling state detection device is a predetermined set state, the controller obtains a wheel speed difference of two of the plurality of wheels based on the wheel speeds of the plurality of wheels detected by the wheel speed detection device. The controller determines whether at least one of the two wheels is in an abnormal state based on the wheel speed difference.

Wheel state obtaining system and wheel state obtaining method

A motion manager configured to request motion of a vehicle according to a kinematic plan on driver assistance of the vehicle to at least one of a plurality of actuators provided in the vehicle includes one or more processors. The one or more processors are configured to receive information indicating a plurality of kinematic plans and classify the information into predetermined items such that a realization method of achieving a purpose of each of the kinematic plans is selectable without specifying or distinguishing a setting source of each of the kinematic plans, arbitrate the kinematic plans, calculate a motion request to the vehicle based on a result of arbitrating the kinematic plans, and distribute the motion request to at least one of the actuators.

Motion manager, vehicle, vehicle control method, and non-transitory storage medium

A vehicle comprises a plurality of drive assist devices configured to implement a plurality of drive assist functions, respectively. The plurality of drive assist devices includes a first drive assist device, which includes an update information generation device configured to generate update information to update a middle point in steering control performed by at least one of the drive assist devices, and a second drive assist device which does not include the update information generation device. The update information generation device in the first drive assist device generates the update information when the first drive assist device receives a notification that permits updating the middle point. The second drive assist device receives the update information from the first drive assist device when the second drive assist device receives the notification.

Control device, method, non-transitory storage medium, and vehicle

A control device for controlling a brake of a vehicle includes an arbitrating unit configured to receive motion requests for a plurality of actuators, which are used for controlling a motion of the vehicle, from a plurality of application requesting units related to driving support functions and to arbitrate the received motion requests, a command distributing unit configured to distribute commands to controllers for controlling the actuators based on an arbitration result obtained by the arbitrating unit, and a feedback controller configured to feed back a control record value indicating the motion of the vehicle, which is measured by using sensor units, to the application requesting units and to realize the motion of the vehicle requested by the application requesting units.

Control device

An information processing apparatus includes a receiver configured to receive a data set including a requested acceleration as information representing movement of a vehicle in a front-rear direction and any one of a steering angle, a yaw rate, and a rotation radius as information representing movement of the vehicle in a lateral direction from each of a plurality of applications, an arbitration unit configured to perform arbitration of information representing the movement of the vehicle in the front-rear direction and arbitration of information representing the movement of the vehicle in the lateral direction based on a plurality of the data sets received by the receiver, and a first output unit configured to output instruction information for driving an actuator based on an arbitration result of the arbitration unit.
