A platoon driving control system of a vehicle includes a detector configured to detect an obstacle positioned in a front according to a driving direction of a vehicle included in a platoon; a processor; and a memory coupled to the processor and storing an algorithm that, when executed by the processor, causes the processor to: determine a braking strategy of the vehicle included in the platoon based on a driving speed of the platoon, and control a driving of the platoon based on the obstacle detected by the detector and the braking strategy.

A method includes obtaining information about a lead vehicle. The lead vehicle is traveling directly ahead of the host vehicle and the information includes velocity of the lead vehicle and a gap g between the host vehicle and the lead vehicle. Based on detecting a change in the velocity of the lead vehicle in the information, a corresponding desired acceleration is computed for the host vehicle using perceived acceleration of the lead vehicle to maintain the gap g within a specified range of gap values. The perceived acceleration of the lead vehicle is based on the change in the velocity indicated by the information. Based on a check of parameters involved in the computing the corresponding desired acceleration, a modified desired acceleration is computed for the host vehicle using a lag for the lead vehicle that results in an intended acceleration of the lead vehicle differing from the perceived acceleration.

A vehicle driving control system includes a road map information updating unit, a control information calculation unit, and a driving control execution unit. Upon determining that a stopped vehicle is present ahead of a target vehicle and that the target vehicle is able to pass by the stopped vehicle, the control information calculation unit calculates control information to be used to restrict a vehicle speed to a first set vehicle speed or less until the target vehicle passes by the stopped vehicle, and calculates, if a door of the stopped vehicle has been opened, the control information to be used to restrict the vehicle speed to a second set vehicle speed or less until a set time period elapses from the opening of the door or until the target vehicle passes by the stopped vehicle. The second set vehicle speed is lower than the first set vehicle speed.

A travel control method includes using the vehicle to autonomously control a travel of the vehicle. The vehicle has an autonomous speed control function for autonomously controlling a traveling speed of the vehicle and an autonomous steering control function for autonomously controlling the steering of the vehicle. The autonomous speed control function includes a curved route speed control function for controlling the traveling speed of the vehicle at a set speed corresponding to the size of a curve of a travel route. The curved route speed control function can be set to ON/OFF. Each of the autonomous speed control function and the autonomous steering control function can be set to ON/OFF. When the autonomous speed control function and the autonomous steering control function are set to ON, the curved route speed control function is operated regardless of whether the curved route speed control function is set to ON or OFF.

A method for providing driving assistance by detecting and warning against areas on one or other side of the road which are obscured by vehicles in other lanes is based on a HD map and includes acquiring location and driving speed of a vehicle which is carrying an apparatus applying the method. The system of the method includes at least one sensor, and environmental information as to surroundings is acquired with location. The speeds of other vehicles relative to the driving speed of the vehicle are calculated, and an instruction to the driver is generated the speed of the vehicle is less than a first predefined value but the speed of the vehicle relative to the driving speeds of the other vehicles is larger than a second predefined value. The apparatus applying the method is also disclosed.

A driving support apparatus according to the invention estimates the position of a moving body by controlling a position estimation unit when the tracking-target moving body leaves a first area or a second area to enter a blind spot area and detects the position of the moving body by controlling a position detection unit when the moving body leaves the blind spot area to enter the first area or the second area. In this manner, the trajectory of the tracking-target moving body is calculated so that the trajectory of the moving body detected in the first area or the second area and the trajectory of the moving body estimated in the blind spot area are continuous to each other and driving support is executed based on the calculated trajectory of the tracking-target moving body.

The movement of the vehicle is controlled so that the travel time does not become long while reducing the fuel consumption of the vehicle. A vehicle control device 1 that automatically controls a speed of a vehicle is configured to include an acceleration/deceleration pattern setting unit 22 that sets a plurality of acceleration/deceleration patterns including acceleration and deceleration in a traveling scheduled zone and sets the speed to be the same in a region between an acceleration region and a deceleration region in each acceleration/deceleration pattern based on traveling history in a traveling scheduled zone.

A driving behavior evaluation device includes a memory and a processor. In a case in which a speed of a target vehicle exceeds a regulation speed and an amount of deviation of the speed of the target vehicle with respect to an average speed of vehicles around the target vehicle is equal to or greater than a threshold value, the processor is configured to set an evaluation of driving behavior of the target vehicle to a lower value than in a case in which the speed of the target vehicle exceeds the regulation speed and the amount of deviation is less than the threshold value.

A cruise control method to control a driven vehicle includes: determining projected speeds of the driven vehicle at each of the predetermined-upcoming locations; determining a plurality of following times at each of the predetermined-upcoming locations of the driven vehicle and the projected speeds of the followed vehicle; determining whether at least one of the plurality of following times is less than the predetermined-minimum time threshold; and in response to determining that at least one plurality of following times is less than the predetermined-minimum time threshold, commanding, by the controller, the propulsion system of the driven vehicle to decrease the commanded axle torque by a torque adjustment in order to prevent each of the plurality of following times at each of the predetermined-upcoming locations from being less than the predetermined-minimum time threshold.

A speed control device sets a target speed of the own vehicle to a basic speed that is a set speed set in advance or sets the target speed of the own vehicle to a basic speed that is a speed equal to or less than the set speed in which a distance to a preceding vehicle is maintained at a predetermined distance or more when there is a preceding vehicle. The speed control device sets the target speed of the own vehicle to a correction speed instead of the basic speed when the speed control device determines that an adjacent lane is congested and a speed difference between the speed of the own vehicle and an average speed or a lowest speed of another vehicle in the adjacent lane is equal to or more than a first reference value.
