Abstract

There is provided a device responding to improper drive for providing drive support based on a driver'"'"'s alertness, the device including a support unit that changes the control mode from a drive support mode to a sleepiness responding mode depending on the driver'"'"'s alertness during an execution of a first control mode, wherein the support unit changes the control mode after the notification unit notifies the driver. The device can provide optimal response to a driver.

Claims

1. A device responding to improper drive for providing drive support based on a driver'"'"'s alertness, the device comprising:

a support processing unit that changes from a first control mode to a second control mode depending on the driver'"'"'s alertness during an execution of the first control mode; and

a notification unit that notifies a driver of a fact that the support processing unit changes the control mode to the second control mode,

wherein the support processing unit changes the control mode after the notification unit notifies the driver.

2. The device according to claim 1, wherein the support processing unit changes the control mode at a time interval after the notification unit notifies the driver.

3. The device according to claim 2, further comprising an input unit that receives an instruction for aborting the change of the control mode to the second control mode from the driver after the notification unit notifies the driver before the support processing unit changes the control mode,

wherein the support processing unit aborts the change of the control mode when the input unit receives the instruction.

4. A device responding to improper drive for providing drive support based on a driver'"'"'s alertness, the device comprising a support processing unit that aborts a first support function for alleviating a drive burden depending on the driver'"'"'s alertness during the first support function and initiates a second support function focusing on drive safety or travel safety.
