The present disclosure relates generally to measuring and testing circuits of towed vehicles. Testing circuits of towed vehicles for proper function is required for safe use of the vehicle. Instruments that currently exist are expensive, the instruments are large in size, use outdated technology to perform the test and do not provide a means to reliably and effectively test braking systems.

A testing system includes a testing device including a display screen. The testing device can display, via the display screen, a representation of a vehicle and oscillators of the vehicle. The testing device transmits a test request that identifies a selected oscillator of the plurality of oscillators for testing. A vehicle receives the test request. An electronic control unit of the vehicle instructs the selected oscillator to generate test signals. The testing calculates a performance metric of the test signals. The testing device determines whether the selected oscillator is properly placed, functioning at a predetermined threshold, or both. Improperly placed or improperly functioning oscillators can be adjusted or replaced.

An equipment inspection system receives data captured by a sensor of an autonomous vehicle (AV). The captured data describes a current state of equipment for servicing the AV. The equipment inspection system compares the captured data to a model describing an expected state of the equipment. The equipment inspection system determines, based on the comparison, that the equipment differs from the expected state. The equipment inspection system may transmit data describing the current state of the equipment to an equipment manager. The equipment manager may schedule maintenance for the equipment based on the current state of the equipment.

A method of estimating the remaining driving distance available from a current charge of a battery of an electrically powered mobility device, wherein the method comprises: a) determining a state of charge of the battery based on a measured battery-related parameter, b) determining a state of health of the battery based on the state of charge, and c) estimating the remaining driving distance that the mobility device can travel with the current charge based on the state of charge and the state of health, wherein step b) involves determining the state of health based on actual consumed ampere hours of the battery.

A method for recognizing the breakdown of an energy reserve device of at least two energy reserve devices of a device for protecting the occupants of a vehicle. The method includes: charging the at least two energy reserve devices to a test voltage level; ascertaining an ambient temperature of the at least two energy reserve devices; acquiring the (overall) capacitance of the at least two energy reserve devices; recognizing the breakdown of an energy reserve device as a function of a floating mean value, which is a function of the ascertained ambient temperature, for the (overall) capacitance and of the acquired (overall) capacitance; updating a floating mean value as a function of the ascertained ambient temperature and the acquired overall capacitance.

A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.
