A braking control apparatus to be installed an electric vehicle includes an acceleration and deceleration operation member, a controller, and a recognizer. The acceleration and deceleration operation member receives an acceleration request in accordance with an operation amount in a first direction from a neutral position, and receive a deceleration request in accordance with an operation amount in a second direction from the neutral position. The controller controls an amount of power regenerated by a rotary electric machine driven by wheels in accordance with the operation amount in the second direction. The recognizer recognizes a preceding vehicle traveling ahead of the electric vehicle. Upon detection of the preceding vehicle at a relative distance from the electric vehicle that is equal to or less than a threshold, the controller performs braking suppression control to decrease the amount of power regenerated in accordance with the operation amount in the second direction.

A method of controlling an electrified vehicle to prevent a collision thereof includes: determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in a traveling path; and when it is determined that the accelerator pedal is erroneously operated, performing braking control such that at least one of hydraulic braking or regenerative braking is selectively performed in a plurality of braking sections determined based on a current vehicle speed and a distance to the obstacle.

The present power conversion device includes an inverter, a step-up/down converter, a first capacitor, a second capacitor, a voltage sensor, a control device, and a backup power supply. The auxiliary device is connected between the first DC power supply and the step-up/down converter, and the control device includes an abnormality determination unit configured to determine that an abnormality has occurred when a control voltage is equal to or lower than a first threshold value, and a control unit configured to execute discharge control when the abnormality determination unit determines that the abnormality has occurred and an inter-terminal voltage measured by the voltage sensor is equal to or lower than a second threshold value.

A railway vehicle is provided with a pantograph movable under the action of a moving device between a raised position, in which it is able to cooperate in contact, in use, with a catenary conductor cable for drawing electrical energy, and a lowered position, in which it is lower than the height where, in use, such catenary is provided; the vehicle is provided with a battery pack and a control system for controlling the moving device and therefore lowering/raising the pantograph; the control system has a microprocessor control unit configured to control the moving device in response to signals containing information indicative of the actual position of the vehicle, and/or indicative of the presence or absence of the conductor cable in the vicinity of the vehicle.

Leading and trailing electrified vehicles are coupled together in a towing arrangement for in-flight transfer of an electrical charge between their battery systems. With the vehicles connected by a towing device, a parking maneuver is initiated in which the trailing vehicle leads the leading vehicle. For the parking maneuver, one of the vehicles is designated (e.g., automatically or by driver agreement) to be an active steering vehicle and the other vehicle to be a passive steering vehicle. At least the passive steering vehicle comprises an electrically-controlled steering actuator. During movement, a turning (e.g., steering angle) of the active steering vehicle is monitored. Based on the turning of the active steering vehicle, an assistive steering angle is determined for the passive steering vehicle. The electrically-controlled steering actuator is commanded according to the assistive steering angle. The parking maneuver may be reverse or forward.

A method for preventing a robot from colliding with a charging base, including: step 1, during a process of moving in a current working area of the robot, detecting, in real time, a reception condition of a base avoidance signal of the robot within a received signal coverage range thereof; and step 2, establishing a safety area in the current working area according to a direction feature relationship between the base avoidance signal and a preset working path of the robot, and before establishing the safety area, according to an orientation relationship between the base avoidance signal and a direction of a current moving path of the robot, marking and establishing a danger area at a position that satisfies a collision avoidance relationship with a current position of the robot, so that the robot avoids the charging base during the process of moving in the current working area.

Various systems and methods associated with protecting a rider of an electric bicycle from hazards while riding their bicycle are described. In some embodiments, the systems and methods enhance the safety of the rider in response current detected conditions surrounding the rider, such as conditions associated with the route or path traveled by the rider, other vehicles within the route or path traveled by the rider, potential hazards within the route or path traveled by the rider, environmental conditions through which the rider is traveling, and so on.

A method according to an exemplary aspect of the present disclosure includes, among other things, controlling an electrified vehicle by adjusting a deceleration rate based on a closing rate of the electrified vehicle to an oncoming object.

In an in-vehicle structure described in the present specification, an electric-power converter is fixed onto a transaxle and positioned in front of a cowl top. The electric-power converter includes a capacitor configured to restrain a high-frequency fluctuation in a voltage of electric power supplied from a battery, and a discharge circuit configured to discharge the capacitor. A connector (a signal connector) to which a wiring harness for communication of a discharge instruction signal to operate the discharge circuit at a time of a collision is connected is provided on a side face of the electric-power converter, the side face of the electric-power converter being facing in a vehicle width direction.

A method controls a movement of a train to a stop at a stopping position between a first position and a second position. The method determines constraints of a velocity of the train with respect to a position of the train forming a feasible area for a state of the train during the movement, such that an upper curve bounding the feasible area has a zero velocity only at the second position, and a lower curve bounding the feasible region has a zero velocity only at the first position. Next, the method controls the movement of the train subject to the constraints.
