Abstract: A driving assistance apparatus includes an estimator and a controller. The estimator estimates a first estimated vehicle speed and a second estimated vehicle speed when there are a first deceleration target and a second deceleration target in a course ahead of a vehicle, and when a driver of the vehicle releases an accelerator pedal. Wherein the first estimated vehicle speed is an estimated vehicle speed of the vehicle at a first target position corresponding to the first deceleration target, and the second estimated vehicle speed is an estimated vehicle speed of the vehicle at a second target position corresponding to the second deceleration target. The controller controls the vehicle to automatically decelerate toward the second target position when the first estimated vehicle speed is greater than a first predetermined value, and when the second estimated vehicle speed is less than a second predetermined value.

Abstract: The driving support apparatus performs deceleration control of the vehicle. The driving support apparatus includes: a sensitivity setting unit configured to set an actuation sensitivity of a deceleration control; a deceleration execution unit configured to execute the deceleration control based on the actuation sensitivity; and a brake operation detection unit configured to detect a brake operation by a driver. The sensitivity setting unit changes the actuation sensitivity based on a control execution count which is the number of executions of the deceleration control and a driver operation count which is the number of operations of the brake operation.

Abstract: Provided is a driving support device (1) including: an operation sensor configured to acquire operation information that is information on an operation on a driving operation device included in an own vehicle; a periphery sensor configured to acquire peripheral information that is information on a target object existing in a periphery of the own vehicle; and a control device configured to execute deceleration support control of supporting a driving operation executed by a driver to decelerate the own vehicle when existence of a target object in front of the own vehicle is detected based on the peripheral information and a predetermined precondition relating to the target object and the own vehicle is satisfied.

Abstract: An elimination work simulator has not only a difference operation processor to attain a difference between work object space data and work space data but also a product operation processor to execute a product operation therebetween. Elimination work space data outputted from the product operation processor is sequentially stored; and at least the latent data of the work object space data outputted from the difference operation processor is stored so as to minimize the amount of data to be preserved. When displaying the work object space data, an animation displaying thereof can be conducted in the same or opposite direction of the order of the work operations by appropriately using elimination work space data and work object space data.
