That is, the example has been described in which the support device 12 starts support that places importance on the safety of driving or traveling after the timing at which the function of supporting to reduce the driving load is turned off. It is not limited. For example, the support device 12 may start support that places importance on the safety of driving or traveling at the same time when the function of supporting to reduce the driving load is turned off.
- the support device 12 may start support that places importance on the safety of driving or traveling before the timing at which the function of supporting to reduce the driving load is turned off. As a result, it is possible to quickly provide support that places importance on driving or traveling safety. Further, the support device 12 determines the timing of turning off the function for assisting to reduce the driving load based on the driver's arousal level, the driving state of the vehicle, etc., and the safety of driving or driving. You may change the relationship with the timing which starts emphasis support so that a driver
- the support device 12 may be configured such that the content of driving support is changed when the arousal level is included in a predetermined range.
- the example in which the control mode is changed after the changed control mode is notified has been described.
- the control mode may be changed after the changed control mode is notified.
- the support device 12 only needs to have a function of changing the control mode in accordance with the driver's arousal level.
