Systems, apparatus and methods to implement sectional design (e.g., in quadrants) of an autonomous vehicle may include modular construction techniques to assemble an autonomous vehicle from multiple structural sections. The multiple structural sections may be configured to implement radial and bilateral symmetry. A structural section based configuration may include a power supply configuration (e.g., using rechargeable batteries) including a double-backed power supply system. The power supply system may include a kill switch disposed on a power supply (e.g., at an end of a rechargeable battery). The kill switch may be configured to disable the power supply system in the event of an emergency or after a collision, for example. The radial and bilateral symmetry may provide for bi-directional driving operations of the autonomous vehicle as the vehicle may not have a designated front end or a back end.

A battery mounting structure in which a battery pack is used as a reinforcement member is provided. An inner sidewall and an outer sidewall of a frame member are connected through a first transmission member. An outer side end of the first transmission member is situated at a level out of the height range of the battery. An inner side end of the first transmission member is attached to the inner sidewall at a level within the height range of the battery, or at a level predetermined distance away from the height range of the battery. A distance between the inner side end and the battery is shorter than that between the outer side end and the battery.

A battery system of a vehicle includes: a housing which is provided between both side members of a vehicle body and arranged in a front portion or a rear portion of the vehicle; and forms an inner space; a battery and a relay provided in the inner space of the housing; and a power connector and a communication connector electrically connected to the battery and the relay and provided in a front surface portion or a rear surface portion of side surfaces of the housing.

A handling unit is in communication with the plurality of location determination devices. The handling unit is configured to receive the position data from the plurality of location determination devices and control separation distances between the plurality of vehicles based on the position data.

An interruption device is provided in a motor vehicle to interrupt a signal line in an emergency operating state. The interruption device includes a fuse and a resistor in the signal line and first and second switches. The fuse is arranged upstream of the resistor in a signal line direction extending from a low-voltage on-board electrical system to a high-voltage on-board electrical system. The first switch is provided in a first electric line connecting the signal line to ground at a connection point downstream of the resistor, and the second switch is provided in a second electric line which connects the signal line to ground at a connection point between the fuse and the resistor. The first and second switches are open during the normal operation of the motor vehicle and are closed in response to the control signal to interrupt the signal line by separating the fuse.

This disclosure details reinforcement assemblies and associated methods for reinforcing a battery pack of an electrified vehicle. An exemplary battery pack may include a battery internal component (e.g., a battery array), an enclosure assembly for housing the battery internal component, and a reinforcement assembly secured to the enclosure assembly. The reinforcement assembly may include a beam and a bracket secured to the beam. The reinforcement assembly may be positioned at expected high impact load locations of the enclosure assembly and is configured for absorbing and transferring energy during vehicle impact loading events, thereby minimizing transfer of the impact loads inside the battery pack where relatively sensitive battery internal components are housed.

A high voltage shut down system and method for an electric vehicle are provided, which perform a high voltage shut down function in connection with a collision detection signal (airbag expansion signal) generated from an airbag controller even when a vehicle is being charged. The high voltage shut down system a third power supply controller which is in an operable state for transmitting power when the vehicle starts and is charged. An airbag control unit is operated by receiving power through the third power supply controller, and is configured to generate an airbag expansion signal when detecting an occurrence of a collision of the vehicle. A high voltage controller is configured to perform a high voltage shut down function in response to receiving the airbag expansion signal.
