A charging system for generating power for an electrical vehicle in motion is provided. The charging system embodies a parallel arrangement of alternators equipped with electromagnetic clutch drives disposed between a starter power source/drive assembly and electric storage device of the electrical vehicle. A charge controller controls the downstream balanced charge to the electric storage device through de-activating or activating the alternators' electromagnetic clutch drives to operate at a set RPM range. The systemic and selective control of the electromagnetic clutches addresses resistance of the alternators at higher RPMs.

The disclosed vehicle braking device controls a hydraulic brake system (2) and a regeneration brake system (3) mounted on a vehicle (1) in accordance with an acceleration value and a brake value, and includes a first divider (11), a second divider (12), and a controller (13). The first divider (11) divides a driver demand torque set according to the accelerator value into a target coast torque and a remaining torque. The second divider (12) divides a sum of a deceleration torque set according to the brake value and the target coast torque divided by the first divider (11) into a hydraulic-brake demand torque and a regeneration-brake demand torque. The controller (13) controls the hydraulic brake system (2), using the hydraulic-brake demand torque, and controls the regeneration brake system (3), using a total regeneration brake torque calculated from the remaining torque and the regeneration-brake demand torque. This configuration can improve the feeling of operating the brake, resolving the feeling of the shortage of deceleration.

A vehicle running control device that is provided with an accelerating-decelerating operation element with an operation range inclusive of a driving range and a braking range includes the following. An input-output section that receives various information including information on a direction in which the vehicle is currently running, a determining section that determines whether the vehicle is in a switch-back state, and an acceleration-deceleration control section that controls the vehicle running. When a braking-driving request value for an operation of the accelerating-decelerating operation element is in the braking range and the determining section determines that the vehicle is in the switch-back state, the acceleration-deceleration control section keeps the braking-driving force at a braking-driving force that is applied to the vehicle when a shift range switch request is accepted.
