A vehicle system, including: an on-board device mounted on a vehicle; and a control device configured to control the on-board device such that the vehicle travels in a target traveling state, wherein the control device includes: a predicting portion that predicts a state of the on-board device when the vehicle travels in the target traveling state; and a modifying portion that modifies the target traveling state when the control device determines based on the state of the on-board device predicted by the predicting portion that an operation of the on-board device needs to be limited.

Vehicle system

An information processing device includes a control unit configured to determine whether to include a regenerative brake in specifications of a proposed vehicle based on regenerative brake operation data acquired while a first vehicle including the regenerative brake is traveling in a predetermined area. The proposed vehicle is a vehicle proposed as a vehicle for a customer to drive in the predetermined area.

Information processing device, information processing method, and information processing program

An information processing apparatus includes a controller. The controller decides whether or not specifications of a proposed vehicle to be proposed to a customer are determined such that the specifications are for an electrified vehicle based on traveling data of a vehicle driven by the customer and outputs the decided specifications.

In a situation where it is predicted that a symbol of target torque reverses by turns to be positive and negative alternately, the hybrid ECU carries out an increasing correction of the target torque, in which the target torque is corrected by increasing the target torque by a set amount &#x394;T in a negative direction when a specific condition, in which it is judged that the degree of the vertical vibration of a vehicle body is larger than a standard value and it is judged there is no acceleration demand, is satisfied, and makes the vibration suppression control torque not to be contained in the target torque when the specific condition is not satisfied. Thereby, even when carrying out free run, the sprung vibration suppression control can be carried out during bad road running, and braking force can be suppressed and fuel consumption can be improved during good road running.

Driving-force control device for vehicle

A vibration suppression torque calculation means calculates a vibration suppression torque for suppressing a sprung vibration. An upper/lower limit value setting means is configured to set, based on a gear ratio of a transmission, upper and lower limit values whose absolute values are increased as the gear ratio is increased. An upper/lower limit restriction means calculates a final vibration suppression torque acquired by using the upper and lower limit values to impose upper/lower limit restriction on the vibration suppression torque. An addition unit sets a value acquired by adding the final vibration suppression torque to a driver required torque to a target torque.

Driving force control device for a vehicle

A steering angle zero point detection unitdetects a zero point of a steering angle of a steering wheel. A zero point history holding unitrecords a detection history of zero points. A characteristic change determination unitdetermines whether or not a characteristic change occurs in the steering transmission system based on a width in the detection history of the zero points.

Characteristic change detection device for steering transmission system

The vehicle control system controls a vehicle based on an estimated gradient value of a travel road. Further, the vehicle control system includes a front/rear acceleration sensor and wheel speed sensors, and a control device for calculating the estimated gradient value. Further, when the vehicle travels, the control device determines whether or not the vehicle is traveling rearward. Then, when the vehicle is traveling forward, the control device calculates the estimated gradient value based on an output signal of the acceleration sensor and output signals of the wheel speed sensors. In contrast, when the vehicle is traveling rearward, the control device calculates the estimated gradient value based on an output signal of the acceleration sensor.
