Systems and methods for managing speed thresholds for a fleet of vehicles are disclosed. Input is used to provide associations between particular weather-relation conditions (such as rain) and arithmetic operations, that may be used to determine a current speed threshold as a function of a local posted speed limit at the current location of a vehicle. The current speed threshold is subsequently used to detect whether vehicles are exceeding the current speed threshold.

A travel assistance method and a travel assistance device for a vehicle is capable of avoiding any risk that may arise. The method includes obtaining a risk potential of an object detected by the vehicle, associating the risk potential of the object with an encounter location at which the object is encountered, accumulating the risk potential at the encounter location, and using the accumulated risk potential to obtain a primary estimated risk potential of the object predicted to be encountered at the encounter location. The primary estimated risk potential is lower than the risk potential obtained when detecting the object. The method further includes obtaining a secondary estimated risk potential using a predicted travel movement of another vehicle that avoids a risk due to the primary estimated risk potential, and when traveling at the encounter location again, autonomously controlling travel of the vehicle using the secondary estimated risk potential.

Provided are methods for controlling vehicle performance based on data associated with an environmental condition.

A vehicle traveling control device is capable of implementing an automatic driving mode that can cause an own vehicle to travel following a preceding vehicle within a predetermined speed range. The vehicle traveling control device includes an acquiring unit that acquires traffic congestion information relating to a traffic congestion nearby the own vehicle, and a control unit that suppresses acceleration of the own vehicle in a first case in which presence of a traffic congestion is detected based on the traffic congestion information, and the own vehicle can be accelerated, during implementation of the automatic driving mode.

A driving support device includes: a front camera configured to acquire image data; and a controller configured to execute driving support control for supporting driving by a driver of a vehicle when the controller determines that a specific display object exists in front of the vehicle based on the image data. The driving support control is control executed depending on the specific display object. The controller is configured to determine whether a conforming operation is being executed by the driver. The controller is also configured to execute, as the driving support control, control having a higher support level indicating a degree of influence on the driver when the controller determines that the conforming operation is not being executed, as compared with a case where the controller determines that the conforming operation is executed.

A method and system for validating the calculated localization (15) of a vehicle are devised. The vehicle (1) is equipped with P independent localization data sources (2-8), with P higher than or equal to 2. The method and system involve the step of comparing data provided by each one of a subset of M, with M lower than or equal to P, of the independent localization data sources with the calculated localization, by correlating an independent localization data source among the subset M if it is above a predetermined Reliability Threshold, and the distance between the data it provides and the calculated localization is lower than a predetermined Compatibility Threshold, and disregarding an independent localization data source among the subset M if either it is below the predetermined Reliability Threshold, or the distance between the data it provides and the calculated localization is higher than the predetermined Compatibility Threshold, and the step of modifying the speed of the vehicle (1) depending on the number of correlated independent localization data sources among the subset M relative to a predetermined Voting Threshold.

A proximity-detection and speed-control system for a materials-handling vehicle, such as a lift truck, is provided with a recommended direction of travel for the vehicle. A proximity sensor is provided to determine the vehicle's proximity to a restricted member, such as another vehicle, a high-value object, a dangerous location, or a pedestrian. If the vehicle is traveling in the recommended direction of travel, the speed control function is disabled. If, however, the vehicle is not travelling in the recommended direction and the proximity sensor indicates the vehicle is within a restricted distance of the restricted member, the speed control function is triggered to restrict the maximum speed of travel of the vehicle and to slow the vehicle if needed.

A vehicular driver assist system includes a forward-viewing camera disposed at and viewing through a windshield of a vehicle. The vehicular driver assist system sets an initial vehicle soft lock speed when speed of the vehicle reaches an initial threshold speed of travel. With the initial vehicle soft lock speed set and with the vehicle speed exceeding the initial vehicle soft lock speed, the system maintains the vehicle speed at the initial vehicle soft lock speed when the vehicle speed reduces to the initial vehicle soft lock speed by coasting. When speed of the vehicle increases by a multiple of a vehicle speed increment above the initial vehicle soft lock speed, the system sets an increased vehicle soft lock speed and maintains the vehicle speed at the increased vehicle soft lock speed when the vehicle speed reduces to the increased vehicle soft lock speed by coasting.

A notification system includes at least one memory in which a program is stored and at least one processor combined with the at least one memory. The at least one processor is configured to execute, by executing the program, an acquisition process of acquiring at least one physical quantity from among acceleration, lateral acceleration, jerk, and vibration amplitude of a truck bed, and a notification process of sending a notification to a remote driving operator in response to a fact that the physical quantity exceeds a first threshold value set for each type of physical quantity.

A driving assistance apparatus assists a driver of a vehicle by performing a deceleration control to decelerate the vehicle when the vehicle makes a right turn or a left turn at an intersection. The driving assistance apparatus is configured to make a magnitude of a deceleration of a vehicle while performing a deceleration control of when a left-or-right-turn-condition is not satisfied smaller than a magnitude of a deceleration of the vehicle while performing the deceleration control of when the left-or-right-turn-condition is satisfied, in a case where a distance between the vehicle and the intersection is equal to or shorter than a distance threshold and the vehicle is predicted to change a moving direction to a particular direction, the left-or-right-turn-condition being a condition that is satisfied when the vehicle is permitted to change the moving direction to the particular direction in/from a traveling lane in which the vehicle is running.
