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: A clutch is controlled to increase torque capacity of the clutch when fluctuations in torsional torque generated in a power transmission route between the clutch and a drive wheel are larger than a specified value during deceleration traveling. Accordingly, engine brake whose magnitude corresponds to an increased amount of the torque capacity of the clutch is actuated. Therefore, the fluctuations in the torsional torque can be suppressed by the engine brake.

Abstract: A tire and a drum are relatively moved so that a pressing load is increased, and stopped when the pressing load becomes a predetermined value lower than a target value. A value of the pressing load and a relative distance between the tire and the drum are measured at timings when a circumferential position of the tire is the same. A dynamic longitudinal spring constant of the tire is calculated by using change amounts of the pressing load and the relative distance. An adjustment amount serving as a distance by which the tire and the drum are relatively moved so that a value of the pressing load when relative movement is stopped becomes the target value is calculated by using the dynamic longitudinal spring constant and a difference between the arrival value and the target value. The tire and the drum are relatively moved by the adjustment amount.
