Several embodiments are provided.

A controller that controls behavior of a vehicle, and includes a control section that controls deceleration of the vehicle. In a situation where the vehicle is being decelerated, when a shift position of the vehicle is switched from a first position, at which power can be transmitted between a drive source (for example, an engine and a travel motor) of the vehicle and a drive wheel of the vehicle, to a second position, at which the power cannot be transmitted between the drive source and the drive wheel in an unlocked state of the drive wheel, the control section executes automatic deceleration control for automatically increasing the deceleration of the vehicle with respect to deceleration depending on a brake operation by the driver of the vehicle.

A system for dynamically calculating collision avoidance metric thresholds for a vehicle includes a vehicle sensor, a passenger position tracking device, and a controller. The controller is in electrical communication with the vehicle sensor and the passenger position tracking device. The controller is programmed to determine a collision avoidance metric using the vehicle sensor, determine an offset to a collision avoidance metric threshold using the passenger position tracking device, and adjust the collision avoidance metric threshold based on the offset. The controller is also programed to compare the collision avoidance metric to the collision avoidance metric threshold and perform an action in response to determining that the collision avoidance metric is less than or equal to the collision avoidance metric threshold.

Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle of a brake pedal 43 increases, and under the condition where a pedal angle is equal to or less than a predetermined pedal angle , an increase rate of the brake valve control pressure Pi with respect to the pedal angle varies.

An apparatus for operating a pedestrian detection and collision mitigation system (PDCMS) of a vehicle is provided. The apparatus includes a front detection sensor that detects a pedestrian in a driving lane of the vehicle and a distance and a relative speed between the pedestrian and the vehicle. A vehicle sensor detects a vehicle speed and a controller executes the PDCMS function based on information detected by the front detection sensor and the vehicle sensor. A warning unit then outputs a notification to a driver regarding a collision of the pedestrian with the vehicle.
