  • Patent number: 12280804
    Abstract: A driving takeover control apparatus is equipped in a vehicle capable of travelling by automated driving and controls a driving takeover operation at a transition from high automated driving to low automated driving. The apparatus includes a driver operation device, a vehicle driving device, an alertness detecting device, a computation control device, and an output limiting device. A driver operates the driver operation device to steer the vehicle and adjust a vehicle speed.
