Abstract
An arithmetic operation device for automobiles includes an arithmetic element state detection unit that detects a parameter indicating a state of an arithmetic element, an external device detection unit that detects a use state of a device that affects the parameter, and a mode selection unit that selects one of a normal mode in which both a basic traveling function unit that can execute control related to a basic traveling function and an automatic driving function unit that can execute control related to an automatic driving function and a degeneration mode in which only the basic traveling function unit is operated, and the mode selection unit selects the degeneration mode when the parameter exceeds a threshold or when it is predicted that the parameter exceeds the threshold.
Claims16
An arithmetic operation device for automobiles mounted on an automobile capable of automatic driving control, comprising:
- an arithmetic element;
- an arithmetic element state detection unit that detects a parameter indicating a state of the arithmetic element;
- an external device detection unit that detects a use state of an external device that affects the parameter from outside of the arithmetic element;
- a basic traveling function unit provided in the arithmetic element and configured to execute control related to a basic traveling function of the automobile;
- an automatic driving function unit provided in the arithmetic element and configured to execute control related to an automatic driving function of the automobile;
- and
- a mode selection unit provided in the arithmetic element and configured to select, based on a detection result of the arithmetic element state detection unit and a detection result of the external device detection unit, one of a normal mode in which both the basic traveling function unit and the automatic driving function unit are operated and a degeneration mode in which only the basic traveling function unit of the basic traveling function and the automatic driving function is operated,
- wherein
- the mode selection unit selects the degeneration mode when the parameter exceeds a threshold or when it is predicted that the parameter exceeds the threshold.

- and
- a mode selection unit provided in the arithmetic element and configured to select, based on a detection result of the arithmetic element state detection unit and a detection result of the external device detection unit, one of a normal mode in which both the basic traveling function unit and the automatic driving function unit are operated, an intermediate mode in which both the basic traveling function unit and the automatic driving function are operated while a function of the automatic driving function unit is compared to that in the normal mode to limit the function, and a degeneration mode in which only the basic traveling function unit is operated,
- wherein
- the mode selection unit selects the degeneration mode when the parameter exceeds a threshold and, on the other hand, selects the intermediate mode when it is predicted that the parameter exceeds a threshold
