A processor-implemented method and/or computer program product selectively blocks a self-driving vehicle's access to a roadway. A vehicle interrogation hardware device receives an autonomous capability signal from an approaching self-driving vehicle. One or more processors compare the predefined roadway conditions to current roadway conditions of the access-controlled roadway. In response to the predefined roadway conditions matching the current roadway conditions of the access-controlled roadway within a predetermined range, the processor(s) determine whether the level of autonomous capability of the approaching self-driving vehicle is adequate to safely maneuver the approaching self-driving vehicle through the current roadway conditions of the access-controlled roadway. In response determining that the level of autonomous capability of the self-driving vehicle is not adequate to safely maneuver the approaching self-driving vehicle through the current roadway conditions of the access-controlled roadway, an automatic barricade controlling device positions an automatic barricade to block the approaching self-driving vehicle from accessing the access-controlled roadway.

Provided is an electric vehicle capable of reciprocally supplying electricity with another vehicle which includes: a power connector; a communication connector; a DC/DC converter used for charging or discharging an internal battery pack; a charging relay for preventing an inrush current during charging; and a display. While moving at the same speed as the other vehicle, the electric vehicle is capable of performing charging or discharging when a connection is maintained between a power connector of the other vehicle and the power connector of the electric vehicle.

The vehicle control system includes an engine, a battery, a motor generator that generates driving power and generates electric power to charge the battery, a power conversion device that generates driving power to the motor generator and charges the battery, and a control device that controls the engine and the power conversion device. The control device controls the engine and the power conversion device and the remaining capacity of the battery is equal to a target value when the remaining capacity of the battery is equal to or less than the lower threshold. The control device reduces the target value of the remaining value of the battery as compared with a case where temperature of the battery is equal to or more than a threshold value when the temperature of the battery is less than the threshold value.

A control system for a hybrid vehicle to start an engine without causing a torque drop is provided. A combined planetary gear unit is configured in such a manner that an input element connected to the engine and an output element are situated between a reaction element connected to a first motor and a fixed element connected to a brake in a nomographic diagram. The first motor is selectively connected to the engine by a clutch. A controller is configured to start the engine by the first motor while engaging the brake to restrict rotation of the fixed element and engaging the clutch.

A control device for a vehicle has a compressor for an air-conditioning device that is driven by a vehicle drive source, and a condenser for the air-conditioning device that is disposed at a front side of the vehicle. A request torque to the vehicle drive source is determined as a sum of an air-conditioning load which is spent for driving the compressor and a running torque necessary to drive the vehicle by a drive wheel. The running torque is calculated based on an accelerator manipulation of a driver. A range-position signal indicating a selected range position is read. A value of the air-conditioning load when the air-conditioning device is in operation and the range position is in a Reverse-range is larger than a value of the air-conditioning load when the range position is in a Drive-range with respect to an identical refrigerant pressure of the air-conditioning device.

In a vehicle including a generator and a drive motor for traveling that operates with generated electric power of the generator, setting a control mode of a carrier frequency used for PWM control for adjusting the electric power of the generator to either of a basic mode or a diffusion mode; acquiring a noise recognition degree suggestion amount suggesting a vehicle situation correlated with a level of a recognition degree of a vehicle user with respect to noise generated by an operation of the generator; executing the diffusion mode in a case where the recognition degree is estimated to be high based on the noise recognition degree suggestion amount; and executing the basic mode in a case where the recognition degree is estimated to be low.

A work vehicle includes a pump brake control determining unit determines that a pump brake control is to be executed for causing a braking force to be generated by using a load on a hydraulic pump during braking. A pump brake torque control unit increases a pump brake torque to correspond to the load on the hydraulic pump during the pump brake control.
