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.
DISTRIBUTED PROCESSING OF VEHICLE SENSOR DATA
In some examples, a first electronic control unit (ECU) receives zone sensor data of a plurality of zones associated with a vehicle. For instance, a respective second ECU and a respective set of zone sensors is associated with each respective zone of the plurality of zones. Based on an indicated driving mode of the vehicle, the first ECU may perform recognition on the zone sensor data from a first zone of the plurality of zones to determine first recognition information. The first ECU receives second recognition information from the respective second ECUs of the respective zones. For instance, the respective second ECUs are configured to perform recognition processing on respective zone sensor data from the set of zone sensors of the respective zones. Based on the first recognition information and the second recognition information, the first ECU sends at least one control signal to at least one vehicle actuator.
