Provided is An apparatus for assisting driving of a host vehicle, the apparatus comprising: a camera mounted to the host vehicle and having a field of view in front of the host vehicle, the camera configured to acquire image data; and a controller including a processor configured to process the image data, and configured to receive a map on which the host vehicle travels from a server, compare a speed limit included in the map with a speed limit included in the image data, and control a display of the host vehicle so as to display the speed limit based on the image data.

A method for determining a risk boundary in response to the plurality of indications of hard braking events wherein the risk boundary is indicative of a plurality of speed flow pairs at which a risk of a hard braking event is below a threshold value, determining, at a road segment level, a set of speed flow pairs of average speed and vehicle count and a plurality of indications of hard braking events , determining a host vehicle speed, and performing at least one of reducing the host vehicle speed and increasing a host vehicle following distance in response to the host vehicle speed exceeding the risk boundary for the vehicle flow density.

Constant-speed-travel-apparatus controlling prime-mover so that mobile-body mounted with the prime-mover travels at constant-speed, includes: function-operation-member being instructed activation of speed-maintaining-function of the mobile-body in response to operation by operator; first-speed-operation-member being instructed the travel-speed of the mobile-body in accordance with operation-amount by the operator; second-speed-operation-member being instructed change of the travel-speed by predetermined amount in response to operation by the operator in state where activation of the speed-maintaining-function has been instructed through the function-operation-member; and electronic-control-unit controlling output of the prime-mover based on the operation-amount of the first-speed-operation-member and number of times of operation of the second-speed-operation-member so that the mobile-body travels at constant-speed in the state. The electronic-control-unit deactivates the speed-maintaining-function and controls the output of the prime-mover based on the travel-speed instructed through the first-speed-operation-member when the operation-amount of the first-speed-operation-member exceeds predetermined operation-amount in the state.

A braking control apparatus to be installed an electric vehicle includes an acceleration and deceleration operation member, a controller, and a recognizer. The acceleration and deceleration operation member receives an acceleration request in accordance with an operation amount in a first direction from a neutral position, and receive a deceleration request in accordance with an operation amount in a second direction from the neutral position. The controller controls an amount of power regenerated by a rotary electric machine driven by wheels in accordance with the operation amount in the second direction. The recognizer recognizes a preceding vehicle traveling ahead of the electric vehicle. Upon detection of the preceding vehicle at a relative distance from the electric vehicle that is equal to or less than a threshold, the controller performs braking suppression control to decrease the amount of power regenerated in accordance with the operation amount in the second direction.

Arrangements described herein can display a set speed deviation for a vehicle using spatiotemporal patterns. A set speed and an actual speed for a vehicle can be acquired. A deviation between the set speed and the actual speed of the vehicle can be determined. Responsive to determining the deviation between the predetermined set speed and the actual speed, a spatiotemporal pattern can be displayed within the vehicle. The spatiotemporal pattern can indicate to a user the deviation between the set speed and the actual speed via the spatiotemporal pattern. In one or more arrangements, the spatiotemporal pattern can be a repeating wave pattern.

A device, system and method for controlling speed of a vehicle are provided. The device includes a locational information module for determining location information and speed; a storage module for storing at least one geographic map including at least one route and a speed limit for the at least one route; a processing module configured to receive the location information, retrieve at least one geographic map based on the location information, determine a speed limit based on the location information and compare the speed of the device to the determined speed limit; and a display module for alerting a user if the speed of the device exceeds the determined speed limit. The system and method can be for communicating a subject vehicle's speed to a central server where it can be utilized to analyze traffic congestion patterns or notify selected companies or individuals.
