Audio-derived information is provided to a vehicle control system of a vehicle by attaching a microphone externally to a vehicle to generate an analog signal in response to sound waves external to the vehicle. An enclosure containing sound-attenuating material mechanically filters low frequency sounds from reaching the microphone transducer. An analog-to-digital converter converts the analog signal to a digital signal. A vehicle data bus transfers the digital signal to the vehicle control system.

Various embodiments include an input circuit comprising: a pull-up resistor having one end thereof connected to an input terminal; a switch unit for establishing/blocking a connection between the other end of the pull-up resistor and a battery; and a dark current reduction unit connected between the other end of the pull-up resistor and the switch unit, and enabling different current paths to be formed in a normal mode and in a low power mode. The dark current reduction unit enables a current path in the low power mode to have a higher resistance than a current path in the normal mode.

A cover for a vehicle electrical system component, such as a pre-fuse assembly, that includes an integrated hinge and locking mechanism. The integrated hinge allows a pivoting cover portion to easily be rotated out of the way in order to give access to an underlying component (e.g., a jump post), while the integrated locking mechanism allows that same cover to be securely locked onto itself when no access is needed. The cover is not limited to a pre-fuse assembly and may be used with other vehicle electrical system components, such as a power distribution device (e.g., a power distribution box, an electrical connection box, a junction box assembly, etc.), a wire harness protector, etc.

A resin structure includes a first resin body, and a second resin body. The second resin body is fit to an outer surface of the first resin body while being slid to one side in a sliding direction along the outer surface of the first resin body. The second resin body includes a pair of end edge portions. The pair of end edge portions extend in inclined directions that are inclined with respect to the sliding direction, such that a gap between the pair of end edge portions in a width direction gradually decreases toward one side of the sliding direction, the width direction being orthogonal to the sliding direction and extending along the outer surface. The first resin body includes a pair of facing surfaces spaced apart in the width direction and facing each other.

An electrical connection box can include a housing and a lower cover that closes a lower part of the housing in which the housing includes an electric wire bundle holder whose lower side open so as to be able to allow insertion of a bonder cap of an electric wire bundle in a state where the electric wire bundle is covered with the bonder cap. The lower cover includes a deep bottom part having a drainage hole. A shallow bottom part can be located above the deep bottom part below the electric wire bundle holder, with the shallow bottom part being formed to include an inclined surface inclined downward toward the deep bottom part, and a state where the bonder cap is inserted into the electric wire bundle holder is maintained on the inclined surface of the shallow bottom part on the lower cover.

A novel busbar, suitable for low-power applications, features a u-shaped extension having a male terminal that fits into and establishes electrical connection with a standard female terminal. The housing of an electrical box including the busbar is modified to receive the female terminal in such a way that Ingress Protection ratings of IP67 and IP69K are maintained within the electrical box. The busbar is not riveted to a thicker busbar terminating with a stud and lug nut, as in legacy configurations, thus being simpler and cheaper to manufacture. The female terminal, once connected to the busbar, is removable by inserting a tool into a dedicated opening within the housing.

An electrical connection box includes a housing member, a first cover member, a second cover member, a hinge structure between the first and the second cover members, and a detachment prevention structure that disables detachment of the second cover member from the first cover member. The hinge structure includes a rotation shaft of the first cover member, a bearing of the second cover member, and a through hole in the first cover member. The through hole allows the bearing to be inserted from a free end and move in a direction that intersects an insertion direction of the bearing and is perpendicular to the axial direction of the rotation shaft to be fitted to the rotation shaft. The detachment prevention structure includes a rotational retaining section of the bearing and a retainer of the housing member.

An electrical junction box has a main body provided with a circuit board, and a cover externally fitted to the main body. The electrical junction box is assembled in a state in which the main body is accommodated in the cover. The main body includes an opposing surface that opposes an inner surface of the cover. The opposing surface has a water capturing hole that is a recess that opens toward the inner surface of the cover. A first opposing distance between the inner surface of the cover and an upper opening edge of the water capturing hole is larger than a second opposing distance between the inner surface of the cover and a lower opening edge of the water capturing hole.

Devices, systems, and methods for constant and reliable power distribution, using a redundant power bridge battery architecture, in autonomous vehicles are described. An example method includes determining that each of a plurality of sensors is operating within in a nominal range for the respective sensor, and distributing, based on the determining, power from at least one alternating current (AC) power source or at least one direct current (DC) power source to at least one power distribution unit (PDU), wherein a first power bridge is coupled to the at least one AC power source and the at least one DC power source and a second power bridge is coupled to the at least one DC power source and the at least one PDU, and wherein the plurality of sensors is used to monitor a health of the vehicle and any single point failure is detectable.

The present disclosure relates to an electronic control apparatus for a vehicle, and the electronic control apparatus of the present disclosure includes: an electronic control element which includes an electronic control board which electrically controls each part of a vehicle, and a heating element which is positioned on a surface of the electronic control board; a cover and a base which accommodate the electronic control element; and a connector which is coupled to the electronic control element, in which an edge part where the cover and the base come into contact with each other is configured in a multi-step bent shape.
