Abstract

A server apparatus capable of communicating with a plurality of vehicles each of which carries a vibration control apparatus for attenuating vibration by adjusting a parameter that affects a predetermined acceleration so that the predetermined acceleration approaches a target acceleration is disclosed. The server apparatus acquires traveling data including a magnitude of the predetermined acceleration generated in each of the vehicles and the target acceleration set for the vehicle every time when each of the vehicles travels on each of sections of a previously divided road, and accumulates the acquired traveling data while being correlated with section identification information. Then, the server apparatus sets the target acceleration which is adequate for each of the vehicles to travel on a scheduled traveling section on the basis of the accumulated traveling data, and transmits the set target acceleration to the vehicle scheduled to travel on the scheduled traveling section.

First claim

What is claimed is:

1. A server apparatus capable of communicating with a plurality of vehicles each of which carries a vibration control apparatus for attenuating vibration of the vehicle by adjusting a parameter that affects a predetermined acceleration so that the predetermined acceleration, which includes at least one of an acceleration in an upward-downward direction, an acceleration in a lateral direction, and an acceleration in a front-back direction, approaches a target acceleration, the server apparatus comprising:
a controller comprising at least one processor,
the controller configured to:
acquire traveling data including a magnitude of the predetermined acceleration generated in each of the vehicles and the target acceleration set for each of the vehicles every time when each of the vehicles, which carries the vibration control apparatus, travels on each of sections of a previously divided road;
accumulate the traveling data while being correlated with section identification information as identification information of the section on which each of the vehicles travels;
acquire a scheduled traveling section of each of the vehicles;
set the target acceleration which is adequate for each of the vehicles to travel on the scheduled traveling section on the basis of the traveling data accumulated while being correlated with the section identification information of the scheduled traveling section; and
transmit the target acceleration to each of the vehicles scheduled to travel on the scheduled traveling section.

2. The server apparatus according to claim 1 , wherein the controller:
acquires traveling environment information including at least one of weather information and traffic status provided when each of the vehicles travels on each of the sections, in addition to the traveling data including the magnitude of the predetermined acceleration generated in each of the vehicles and the target acceleration set for each of the vehicles, every time when the vehicle, which carries the vibration control apparatus, travels on each of the sections;
accumulates the traveling data and the traveling environment information while being correlated with the section identification information of the section on which each of the vehicles travels; and
extracts the traveling data corresponding to a traveling environment approximate to a traveling environment provided when each of the vehicles travels on the scheduled traveling section, from the traveling data accumulated while being correlated with the section identification information of the scheduled traveling section so that the target acceleration, which is adequate for each of the vehicles to travel on the scheduled traveling section, is set on the basis of the extracted traveling data.

3. The server apparatus according to claim 1 , wherein:
when the vehicle is provided with an operation control apparatus for allowing a subject vehicle to perform autonomous traveling in accordance with a predetermined operation command;
the controller is further configured to generate the operation command adequate for the vehicle and transmit the generated operation command to the operation control apparatus.

4. The server apparatus according to claim 2 , wherein:
when the vehicle is provided with an operation control apparatus for allowing a subject vehicle to perform autonomous traveling in accordance with a predetermined operation command;
the controller is further configured to generate the operation command adequate for the vehicle and transmit the generated operation command to the operation control apparatus.
