Abstract

Determination on impossibility of automated driving along a predetermined travel route is performed at an early stage. A vehicle's heat dissipation performance (a value of a vehicle performance parameter correlating to a vehicle performance used to determine whether the automated driving is possible) and an amount of heat dissipation required to implement the automated driving of the vehicle along the travel route (a value of a necessary performance parameter correlating to the vehicle performance required to implement the automated driving of the vehicle along the travel route) are estimated. If the value of the vehicle performance parameter is less than the value of the necessary performance parameter, the automated driving of the vehicle along the predetermined travel route is determined non-executable, and any of the following is performed: setting of another travel route; return of the vehicle to the repair shop; or evacuation of the vehicle.

Claims5

Dependent claims

An automated driving system for controlling automated driving of a vehicle along a predetermined travel route, the automated driving system comprising:

a vehicle performance estimation section to estimate, at least either before a start of the automated driving or during the automated driving along the predetermined travel route, a value of a vehicle performance parameter correlating to a vehicle performance used to determine whether or not the automated driving is possible when the automated driving of the vehicle is performed along the predetermined travel route;
a necessary performance estimation section to estimate a value of a necessary performance parameter correlating to the vehicle performance required to implement the automated driving of the vehicle along the predetermined travel route;
and
an automated driving control section to implement the automated driving of the vehicle along the predetermined travel route on a condition that the value of the vehicle performance parameter is greater than or equal to the value of the necessary performance parameter, and also not to implement the automated driving of the vehicle along the predetermined travel route on the condition that the value of the vehicle performance parameter is less than the value of the necessary performance parameter.
