In-vehicle backup control apparatus and in-vehicle backup apparatus

An in-vehicle backup control apparatus includes a discharge circuit that discharges a power storage unit and a control unit that controls the discharge circuit. The control unit sets either one of a superimposable voltage or a supply completion voltage as an interruption threshold value, the superimposable voltage being set as a voltage condition of the power storage unit when electric power is supplied simultaneously to a plurality of target loads during an abnormal state, and the supply completion voltage being set in association with one of the plurality of target loads. The control unit interrupts or delays the supply of electric power to the one of the plurality of target loads to prohibit the plurality of target loads from simultaneously operating if a charge voltage of the power storage unit reaches a value less than or equal to the interruption threshold value during the abnormal state.

Vehicle operation with interchangeable drive modules

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A vehicular autonomous driving system includes a time division multiplexed (TDM) bus, an autonomous driving (AD) controller coupled to the TDM bus, and a plurality of AD sensors coupled to the TDM bus. The AD sensors are configured to collect AD data and transmit collected AD data to the AD controller on the TDM bus in an assigned time slot at a first power level. A first AD sensor of the plurality of AD sensors is configured to, based upon collected AD data, detect an AD emergency event. In response to the detection, the first AD sensor is configured to transmit an AD emergency message on the TDM bus in a non-assigned time slot and at a second power level that exceeds the first power level. The AD sensor may transmit the AD emergency message in a particular sub-slot of the non-assigned time slot.
