Driving assist device
First Claim
1. A driving assist device mounted in a vehicle to assist a driver in driving the vehicle through detecting a state of the driver, the vehicle being switchable between a manual driving state in which driving operations for acceleration, braking and steering are manually performed by the driver and an automated driving state in which at least one of the driving operations is performed automatically,the driving assist device comprising:
- a processor comprising circuitry,a memory storing a computer program;
a driver state detection unit by having the processor executes the computer program is configured to detect whether the state of the driver is an inattentive state;
an alerting unit by having the processor executes the computer program, when the inattentive state of the driver or the excited state of the driver is detected, alerts the driver;
a driving operation unit comprising a steering wheel that is operated by the driver to perform the driving operations; and
a driving state switching unit by having the processor executes the computer program, when the driver'"'"'s operation of the driving operation unit is detected during the automated driving state of the vehicle, switches at least one of the driving operations in the automated driving state to the manual driving state,wherein;
when at least one of the driving operations in the automated driving state is switched to the manual driving state by the driving state switching unit, the driver state detection unit detects whether the state of the driver is an excited state; and
when the excited state of the driver is detected, the alerting unit alerts the driver.

Abstract
A driving assist device includes a driver state detection unit for detecting an inattentive state as a driver state, an alerting unit for altering the driver upon detection of the inattentive state of the driver, a driving operation unit for being operated by the driver for driving operations; and a driving state switching unit that switches at least one of the driving operations in an automated driving state to a manual driving state when the driver'"'"'s operation of the driving operation unit is detected during the automated driving state of the vehicle. When at least one of the driving operations in the automated driving state is switched to the manual driving state by the driving state switching unit, the driver state detection unit detects whether the state of the driver is an excited state. When the excited state of the driver is detected, the alerting unit alerts the driver.

5. A driving assist method to be applied to a vehicle to assist a driver in driving the vehicle through detecting a state of the driver, the vehicle being switchable between a manual driving state in which driving operations for acceleration, braking and steering are manually performed by the driver and an automated driving state in which at least one of the driving operations is performed automatically,
the driving assist method performed by a processor executing a computer program stored in a memory comprising: -
a driver state detection process performed by the processor that detects whether the state of the driver is an inattentive state; an alerting process that alerts the driver when the inattentive state of the driver is detected; and a driving state switching process that, when the driver'"'"'s operation of the driving operation unit is detected during the automated driving state of the vehicle, switches at least one of the driving operations in the automated driving state to the manual driving state, wherein; when at least one of the driving operations in the automated driving state is switched to the manual driving state in the driving state switching process, it is detected in the driver state detection process whether the state of the driver is an excited state; and in the alert process, the driver is alerted when the excited state of the driver is detected.

6. A driving assist device mounted in a vehicle to assist a driver in driving the vehicle through detecting a state of the driver, the vehicle being switchable between a manual driving state in which driving operations for acceleration, braking and steering are manually performed by the driver and an automated driving state in which at least one of the driving operations is performed automatically,
the driving assist device comprising: -
a processor comprising circuitry, a memory storing a computer program; a driver state detection unit by having the processor executes the computer program is configured to detect whether the state of the driver is an inattentive state or an excited state; an alerting unit by having the processor executes the computer program, when the inattentive state of the driver or the excited state of the driver is detected, alerts the driver; a driving operation unit comprising a steering wheel that is operated by the driver to perform the driving operations; and a driving state switching unit by having the processor executes the computer program, when the driver'"'"'s operation of the driving operation unit is detected during the automated driving state of the vehicle, switches at least one of the driving operations in the automated driving state to the manual driving state, wherein; the driving state detection unit by having the processor executes the computer program detects the inattentive state of the driver both in the manual driving state and in the automated driving state, and when at least one of the driving operations in the automated driving state is switched to the manual driving state by the driving state switching unit, the driver state detection unit detects that the state of the driver is the excited state and not the inattentive state; and when the excited state of the driver is detected, the alerting unit alerts the driver.
