摘要： This vehicle control device 10 is provided with: a current gear stage selection unit 13 which selects a current gear stage, which is the gear stage of the vehicle in the present travel state; a travel segment determination unit 15 which determines the next travel segment forwards in the direction of travel of the vehicle V; and a shift control unit 17 which, in the case that the current gear stage selection unit 13 has newly selected a target gear stage lower than the current gear stage during travel of the vehicle V in the current gear stage in the current travel segment, if the next travel segment can be traveled in the current gear stage and the amount the vehicle V will lose speed after traveling the current travel segment is less than or equal to a prescribed threshold value, controls shifting of the gear stage such that downshifting from the current gear stage to the target gear stage is suppressed and the current gear stage is maintained. Even in a state in which downshifting is suppressed, if the state of the vehicle the satisfies a prescribed condition, then the shift control unit 17 controls shifting of the gear stage so as to downshift to the target gear stage without suppression of downshifting.

摘要： A vehicle speed control device 1 includes a lane detection unit 120 configured to detect a road outside line of a lane on which a host vehicle V is traveling, a target detection unit 121 configured to detect a target that is present outside the road outside line, and a speed control unit 123 configured to control a speed of the host vehicle V such that the host vehicle V passes a lateral side of the target at a speed lower than a speed of the host vehicle V when the target has been detected. After the host vehicle V has passed the lateral side of the target, the speed control unit 123 accelerates the host vehicle V up to the speed when the target has been detected.

摘要： A vehicle control device controls operation of a vehicle provided with a transmission having a direct gear and normal gears including an overdrive gear having a lower gear ratio than the direct gear. The device includes a travel segment determination unit which determines a forward travel segment having a different road slope from a current travel segment, a current gear position selection unit that selects a current gear position in accordance with a shift pattern, a forward gear position selection unit that selects a forward gear position based on a travel resistance of the vehicle in the forward travel segment, and a shift control unit that maintains a gear position as the direct gear while the vehicle travels in the forward travel segment, when a gear position of the transmission in the current travel segment is the overdrive gear and the forward gear position is the direct gear.

摘要： A control device includes an engine starting unit that starts an engine on a condition that a first voltage is supplied, an engine control unit that controls an operation of the engine starting unit, and a transmission control unit that drives a transmission on a condition that a second voltage, which is higher than the first voltage, is supplied. The transmission control unit sends an engine start permission signal to the engine control unit in a case where a voltage of power supplied from a battery is the second voltage or higher, and the engine control unit permits the engine starting unit to start the engine on a condition that the engine control unit receives the engine start permission signal.

摘要： This control device can suppress decreases in communication speed. The control device is provided with: a determination unit which determines whether or not a peripheral vehicle positioned in the periphery of a first vehicle is traveling on the same travel road as the first vehicle; a relay vehicle selection unit which, in inter-vehicle communication for communicating between vehicles, selects, as a second vehicle for relaying data from the first vehicle, one of the peripheral vehicles determined by the determination unit to be traveling on the same travel road as the first vehicle; and an inter-vehicle communication control execution unit which executes control for the inter-vehicle communication unit of the first vehicle to allow inter-vehicle communication with the second vehicle.

摘要： Provided is a steering assistance device, and a demarcation line detection unit 100 detects left and right lane demarcation lines for a lane in which a vehicle is travels. A horizontal velocity measurement unit 101 calculates the horizontal velocity, which is a velocity component of the vehicle in a direction perpendicular to the lane. An assistance unit 11 performs steering assistance for the vehicle so that the vehicle travels parallel to the left and right lane demarcation lines. In a case where the horizontal velocity equal to or greater than a prescribed velocity and the center of the vehicle is separated from the center between the left and right lane demarcation lines by equal to or greater than a prescribed distance, a steering control unit 102 starts the steering assistance of the vehicle by the assistance unit 11.
