A platooning controller includes a processor configured to share information about a first platooning vehicle of a group of platooning vehicles with other platooning vehicles of the group of platooning vehicles when a brake of the first platooning vehicle breaks down during platooning and to perform braking control, and a storage configured to store data and an algorithm for platooning and braking control by the processor. The processor is configured to rearrange the group of platooning vehicles depending on a location where the first platooning vehicle is arranged in a platoon line, to decelerate the first platooning vehicle and a second platooning vehicle in front of the first platooning vehicle, and to center the first platooning vehicle and the second platooning vehicle to perform the braking control.

One general aspect includes a system to commence host vehicle movement upon being stopped behind a target vehicle, the system includes a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to: detect the target vehicle as being stopped along a route; cause the host vehicle to stop at a first distance from the target vehicle; detect a transition of one or more brake lights of the target vehicle from an ON state to an OFF state; and after the one or more brake lights are detected to transition from the ON state to the OFF state, cause the host vehicle to move at a slow speed in the direction of the target vehicle.

A vehicle comprising an internal combustion engine, a preceding vehicle information acquiring device for acquiring preceding vehicle information relating to a preceding vehicle, including a parameter relating to a distance between vehicles which becomes greater the wider the distance between a host vehicle and the preceding vehicle, and an electronic control unit for controlling the internal combustion engine, in which, the electronic control unit is configured to initiate an idle reduction mode where the internal combustion engine is made to automatically stop when a preset engine stop condition stands and to continue the idle reduction mode if the preceding vehicle is decelerating or has stopped and to make the internal combustion engine automatically restart if the preceding vehicle is accelerating or is running at an equal speed when the parameter becomes a first predetermined value or more during the idle reduction mode.

A vehicle controlling apparatus includes a setting unit and an acquiring unit. The setting unit is configured to set a target inter-vehicle distance. The acquiring unit is configured to acquire position information of a temporary stopping location on a traveling route on which an own vehicle travels. The setting unit is configured to, on a condition that the own vehicle travels to follow a preceding vehicle, and that the acquiring unit has acquired the position information of the temporary stopping location, make a setting change to make the target inter-vehicle distance greater than a normal setting value when a distance from the own vehicle to the temporary stopping location reaches a predetermined distance, and make a setting change to bring the target inter-vehicle distance closer to the normal setting value in accordance with the distance until the own vehicle reaches the temporary stopping location.

A method for controlling a drive unit of a motor vehicle include acquiring a speed instruction, measuring the speed of the motor vehicle, and computing a control instruction for the drive unit on the basis of the measured speed and of the speed instruction. When the motor vehicle is moving forwards and should be stopped, the speed instruction is determined so as to be strictly less than zero.

A vehicle control device comprises an operation amount sensor for measuring an operation amount of an accelerator element, an object sensor for detecting an object ahead of a vehicle, and a controller for applying a normal operation drive force which is determined depending on the operation amount to the vehicle. The controller executes an adaptive cruise control for applying a drive force required for an acceleration of the vehicle to become equal to an adaptive cruise control acceleration to the vehicle. The adaptive cruise control acceleration is an acceleration which increases as a difference between an inter-vehicle distance from the vehicle to an objective-forward-vehicle and a target inter-vehicle distance increases. When an erroneous operation start condition becomes satisfied, the controller ends the adaptive cruise control, and executes an erroneous operation related control for applying a drive force which is smaller than the normal operation drive force to the vehicle.
