US Patent 11420627 Driving assistance device

A driving assistance device is configured to perform deceleration control in such a way that a vehicle stops at a target position determined by a deceleration target ahead of the vehicle. The driving assistance device is configured to calculate a predicted vehicle speed of the vehicle at the target position when the deceleration control is performed, based on the current vehicle speed of the vehicle, the distance to the target position, and the deceleration that varies depending on the type of the deceleration target. When the predicted vehicle speed is higher than a predetermined value, the driving assistance device is configured not to perform the deceleration control or to reduce the deceleration in the deceleration control.
